  • Assessment of the impact of the scanner-related factors on brain morphometry analysis with Brainvisa

    Mahsa Shokouhi
    20 Dec 2011 | 6:00 pm
    Background: Brain morphometry is extensively used in cross-sectional studies. However, the difference in the estimated values of the morphometric measures between patients and healthy subjects may be small and hence overshadowed by the scanner-related variability, especially with multicentre and longitudinal studies. It is important therefore to investigate the variability and reliability of morphometric measurements between different scanners and different sessions of the same scanner. Methods: We assessed the variability and reliability for the grey matter, white matter, cerebrospinal fluid…

    26 Jan 2012 | 6:00 pm
    Background: Mitral valve thickness is used as a criterion to distinguish the classical from the non-classical form of mitral valve prolapse (MVP). Classical form of MVP has been associated with higher risk of mitral regurgitation (MR) and concomitant complications. We sought to determine the relation of mitral valve morphology and motion to mitral regurgitation severity in patients with MVP. Methods: We prospectively analyzed transthoracic echocardiograms of 38 consecutive patients with MVP and various degrees of MR. In the parasternal long-axis view, leaflets length, diastolic leaflet…

  • Shortening of Atrioventricular Delay at Increased Atrial Paced Heart Rates Improves Diastolic Filling and Functional Class in Patients with Biventricular Pacing

    Reza Rafie
    23 Jan 2012 | 6:00 pm
    Background: Use of rate adaptive atrioventricular (AV) delay remains controversial in patients with biventricular (Biv) pacing. We hypothesized that a shortened AV delay would provide optimal diastolic filling by allowing separation of early and late diastolic filling at increased heart rate (HR) in these patients. Methods: 34 patients (75+/-11 yrs, 24M, LVEF 34+/-12%) with Biv and atrial pacing had optimal AV delay determined at baseline HR by Doppler echocardiography. Atrial pacing rate was then increased in 10 bpm increments to a maximum of 90 bpm. At each atrial pacing HR, optimal AV…

  • Fixation based event-related fmri analysis: Using eye fixations as events in functional magnetic resonance imaging to reveal cortical processing during the free exploration of visual images

    Jan Bernard C. Marsman
    31 Jan 2012 | 11:00 pm
    AbstractEye movements, comprising predominantly fixations and saccades, are known to reveal information about perception and cognition, and they provide an explicit measure of attention. Nevertheless, fixations have not been considered as events in the analyses of data obtained during functional magnetic resonance imaging (fMRI) experiments. Most likely, this is due to their brevity and statistical properties. Despite these limitations, we used fixations as events to model brain activation in a free viewing experiment with standard fMRI scanning parameters. First, we found that fixations on…

  • Enhancing the utility of complex-valued functional magnetic resonance imaging detection of neurobiological processes through postacquisition estimation and correction of dynamic B0 errors and motion

    Andrew D. Hahn
    31 Jan 2012 | 11:00 pm
    AbstractFunctional magnetic resonance imaging (fMRI) time series analysis is typically performed using only the magnitude portion of the data. The phase information remains unused largely due to its sensitivity to temporal variations in the magnetic field unrelated to the functional response of interest. These phase changes are commonly the result of physiologic processes such as breathing or motion either inside or outside the imaging field of view. As a result, although the functional phase response carries pertinent physiological information concerning the vasculature, one aspect of which…

  • Nonlinear estimation of neural processing time from BOLD signal with application to decision-making

    Claudinei Eduardo Biazoli
    31 Jan 2012 | 11:00 pm
    AbstractThe extraction of information about neural activity timing from BOLD signal is a challenging task as the shape of the BOLD curve does not directly reflect the temporal characteristics of electrical activity of neurons. In this work, we introduce the concept of neural processing time (NPT) as a parameter of the biophysical model of the hemodynamic response function (HRF). Through this new concept we aim to infer more accurately the duration of neuronal response from the highly nonlinear BOLD effect. The face validity and applicability of the concept of NPT are evaluated through…

  • Brain regions involved in human movement perception: A quantitative voxel-based meta-analysis

    Marie-Hélène Grosbras
    31 Jan 2012 | 11:00 pm
    AbstractFace, hands, and body movements are powerful signals essential for social interactions. In the last 2 decades, a large number of brain imaging studies have explored the neural correlates of the perception of these signals. Formal synthesis is crucially needed, however, to extract the key circuits involved in human motion perception across the variety of paradigms and stimuli that have been used. Here, we used the activation likelihood estimation (ALE) meta-analysis approach with random effect analysis. We performed meta-analyses on three classes of biological motion: movement of the…

  • Staying responsive to the world: Modality-specific and -nonspecific contributions to speeded auditory, tactile, and visual stimulus detection

    Robert Langner
    31 Jan 2012 | 11:00 pm
    AbstractSustained responsiveness to external stimulation is fundamental to many time-critical interactions with the outside world. We used functional magnetic resonance imaging during speeded stimulus detection to identify convergent and divergent neural correlates of maintaining the readiness to respond to auditory, tactile, and visual stimuli. In addition, using a multimodal condition, we investigated the effect of making stimulus modality unpredictable. Relative to sensorimotor control tasks, all three unimodal detection tasks elicited stronger activity in the right temporo-parietal…

    Hidekatsu Kuroda
    31 Jan 2012 | 11:00 pm
    AbstractAcoustic radiation force impulse (ARFI) imaging is a new technology used to determine liver elasticity. We report the case of a patient that survived hyperacute-type acute liver failure (ALF) and who showed a dramatic change in the value of shear wave velocity (SWV) measured by ARFI, which corresponded with the severity of her liver damage. The value of SWV increased significantly up to 3.6 ± 0.3 m/s during the encephalopathy phase and then decreased along with the recovery of liver function, the blood flow of the right portal vein, and the liver volume. These findings suggest the…

  • Transplacental fetal therapy for junctional ectopic tachycardia

    Kaori Ishikawa
    31 Jan 2012 | 11:00 pm
    AbstractJunctional ectopic tachycardia (JET) is a rare type of tachyarrhythmia. A 39-year-old woman was transferred to our hospital for fetal tachyarrhythmia at 32 weeks' gestation. Fetal cardiac sonography revealed atrial and ventricular rates of 120–130 and 175–230 bpm, respectively, without 1:1 atrioventricular relationship. As ventricular tachycardia was considered to be the most probable diagnosis, transplacental therapy with digoxin and sotalol was done with partial response. Diagnosis of JET was made after birth. Although fetal JET is rare and prenatal diagnosis and treatment of…

    Purpose: We hypothesized that quantitative PET parameters may have predictive value beyond that of traditional clinical factors such as the International Prognostic Score (IPS) among Hodgkin's disease (HD) patients. Methods: Thirty HD patients treated at presentation or relapse had staging and interim-treatment PET-CT scans. The majority of patients (53%) had stage III-IV disease and 67% had IPS >2. Interim-treatment scans were performed at a median of 55 days from the staging PET-CT. Chemotherapy regimens used: Stanford V (67%), ABVD (17%), VAMP (10%), or BEACOPP (7%). Hypermetabolic…

      One moment I was mohawk skating around a corner of the track. I had just cleared the stretch that had been giving me difficulty on my previous few go-arounds, and was mentally giving myself a little cheer for having made it. The next moment is captured in my head in slow motion, with brief flashes of blurry nonsense. My front foot hit one of the little orange cones that was defining the edge of the obstacle course. Then it hit the next cone, and a third, and I went down. My back foot, already facing backwards, decided to stay that way as I flew and fell. There was a distinct POP that…

  • Iodinated Contrast Media Associated with High Risk of Thyroid Abnormality, Study

    26 Jan 2012 | 12:59 am
    In a recent study, researchers said that iodinated contrast media, used in certain imaging procedures, may cause disturbance in thyroid function. It can increase the risk of hyperthyroidism. The study was carried out by a team from Brigham and Women's Hospital and Massachusetts General Hospital, Harvard Medical School, Boston. More details are highlighted in Archives of Internal Medicine. Researchers reported "Iodinated contrast media (ICM) are commonly administered pharmaceutical agents.

  • Thomas Jefferson University Hospital Offers New Lung Cancer Screening Program

    25 Jan 2012 | 2:05 am
    A team of experts at Thomas Jefferson University Hospital has recently designed a new program for screening, earlier detection, and treatment of lung cancer. The latter is a common form of cancer that is characterized by high mortality rates. A recent trial, the National Lung Cancer Screening Trial, involved 53,000 ongoing and ex-heavy smokers, between 55 and 74 years. It indicated that 20% less mortality cases were reported among those screened with low-dose spiral or helical CT rather than those screened with conventional X-ray. Mani Kavuru, MD, director of the Division of Pulmonary and…

  • Benign Versus Atypical/Malignant Meningiomas on DWI

    Sumer Sethi
    26 Jan 2012 | 3:48 am
    Benign meningiomas have a variable appearance on diffusion-weighted images, they tend to have higher Dav values compared with normal brain, with the exception of densely calcified or psammomatous meningiomas, which may have a low Dav.  Furthermore, the average Dav values of malignant and atypical meningiomas are significantly lower compared with benign meningiomas.  It seems that the quantification of the diffusion constant may reliably predict the histopathologic features of meningiomas before resection, useful because atypical and malignant meningiomas are more prone to recurrence…

  • Term of the day: "Mini Brain Sign"

    Sumer Sethi
    26 Jan 2012 | 12:27 am
    Many tumors involving the axial skeleton can be expansile, have low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, and involve the entire vertebral body. These imaging characteristics are nonspecific. Minibrain appearance has been found characteristic of Plasmacytoma. The characteristic appearance of thickened cortical struts is probably a result of a stress phenomenon from the lytic process of the plasmacytoma forcing the remainder of the bone to increase thickness as a compensatory response to weakening bone. Requesting readers for any characteristic…

  • Follow up on US FDA withdrawal of CardioGen-82

    Sumer Sethi
    25 Jan 2012 | 11:45 am
    FDA told physicians to stop using the CardioGen-82 some time back after identifying an increased risk of radiation exposure, Following which it was withdrawn. Now US FDA says that "improper usage" of the generator at certain sites is the likely cause of radiation exposure to patients and not faulty devices.  According to them increased radiation exposure seen at specific sites was likely was due to the administration of CardioGen-82 generator eluates that contained excessive concentrations of strontium-82 (Sr-82) and strontium-85 (Sr-85).

  • Could Therapeutic Ultrasound Replace Chemical Medications?

    blogger
    26 Jan 2012 | 5:32 pm
    Some medical and scientific communities are advocating therapeutic ultrasound machine technology as a more effective treatment for certain patients that suffer from chronic pain, than prescription chemical medications. The primary basis for this endorsement is that research has shown that the body will actually heal more quickly when pain medications are not used as a crutch to mask the pain. Chiropractors often treat patients with arthritis and sports injuries with neuromuscular stimulators. The neuromuscular stimulators used in therapeutic ultrasound are extremely effective at stimulating…

  • Obstetrics and 4-D Ultrasounds

    blogger
    14 Dec 2011 | 6:40 pm
    Ultrasound technology was first introduced in obstetrics about thirty years ago. In obstetrics, standard ultrasound machines produce a two-dimensional image of a developing fetus. It is used to obtain measurements, detect any abnormalities, and to determine gestational age. However, with a 2-D ultrasound machine, the image is usually grainy and it requires a qualified physician or sonographer to identify different parts of the body or problems. One of the undeniable advantages to 3-D and 4-D ultrasound imaging is that it provides patients and doctors with multi-planar images. While 3-D…

  • Relieve Pain with Ultrasound Therapy in the Privacy of Your Home

    blogger
    1 Dec 2011 | 6:47 pm
    People tend to think about ultrasound machines in terms of obstetrics, but not everyone is aware of their use in regard to physical therapy treatment. Today, ultrasound machines are more portable than ever, and they are now available to be used at home for therapy and pain relief. Home ultrasound machine units can be as effective at relieving pain as professional ultrasound machines. Professional ultrasound machines use a continuous wave and the home units use pulsed waves, which makes them safer for the general public to use. Since they are safer to use, patients that use a home ultrasound…

    Medical innovation and technology is always evolving. For example, in 2005, a doctor by the name of Scott Dulchavsky conducted a reach project on the International Space Station (ISS) that involved teaching astronauts how to use a portable ultrasound machine, while they were on a space mission. With the help of doctors at the base, the astronauts were able to diagnose some of their own medical issues. This research project benefited and inspired more improved medical equipment technology, in the following years, both on the ground and in space. In fact, the original ultrasound machine that…

    In 2005, a Detroit-based trauma surgeon by the name of Dr. Scott Dulchavsky, began to study the use and effectiveness of ultrasound machine technology in outer space Since astronauts in space had no access to doctors or other medical professionals during a space mission, Dr. Dulchavsky’s ultimate goal in the study was to provide a way for the astronauts to assist in diagnosing their own medical problems. Based on his research, he concluded that ultrasound machine technology would be effective in diagnosing approximately five hundred various health problems that could occur while astronauts…

    14 Jan 2012 | 9:47 am
    There is a lot of misinformation going around the internet about what we do... and unfortunately, there are a lot of people looking to make money off of individuals who would like to become Radiologic Technologists, but may not know the difference between that and a "x-ray technician" or simply an "x-ray tech." I subscribe to google alerts for "radiography", and this morning I received this link:  http://www.stridemagazine.com/what-is-the-yearly-salary-of-the-radiologist#comment-3346 It's not the first link that I have come across with loads of inaccurate information.  Its title…

  • Tech Tips: Patient Identification

    Jeremy
    11 Jan 2012 | 12:36 pm
    The number one patient safety goal in the country is proper identification of patients.  There have been many unnecessary procedures and/or surgeries performed on patients over the years that should have been prevented because one or more members of the health care team either neglected to, or were afraid to check the patient’s ID. About 8 years ago, I performed an x-ray series on the wrong patient, and I will never do it again.  I was at an outpatient imaging center (where no wrist bands were worn).  I called the patient’s name, and an elderly woman stood up and followed…

I have begun work on my own radiography book that has taken up quite a bit of my time.  I have this problem where I get really excited about a particular activity or project and I tend to spend all of my time and energy on that one thing.  This can be a great attribute when you are being paid to perform that task for an employer, but it can also make regular activities (like eating, sleeping, blogging, etc.) take a back seat, and for that, I apologize. I definitely have some great posts coming up soon as I have gathered some…

    There is quite the controversial discussion going on around town.  I have heard complaints from several students across the country, some of my own students, technologists in the hospitals and imaging centers, and even online in Radiology forums about how many new grads there are in the Radiologic Sciences Programs when there are "so few jobs" out there.  I have heard comments like, "the schools are saturating the job market" and "it all comes down to greed with college administrators."  I have even heard allegations that the hospitals pay off the schools to have students…

    I've been tossing around the idea of creating continuing education courses to place on this blog, but before I get carried away, I'd like your opinion... In the side-bar, I have placed a poll asking if my readers would like to see CEU's offered on my blog.  I would appreciate it if my readers would take the poll to give me an idea of whether or not the courses would be well-received here. Any time I have seen CE credits offered on a website, it seems to be in one format only.  If you answer "yes" in the poll, and if you could spare a minute, please let me know what kinds of formats…
