  • Noise-compensated Homotopic Non-local Regularized Reconstruction for Rapid Retinal Optical Coherence Tomography Image Acquisitions

    Chenyi Liu
    14 Oct 2014 | 5:00 pm
    Background: Optical coherence tomography (OCT) is a minimally invasive imaging technique, which utilizes thespatial and temporal coherence properties of optical waves backscattered from biological material.Recent advances in tunable lasers and infrared camera technologies have enabled an increase in theOCT imaging speed by a factor of more than 100, which is important for retinal imaging where wewish to study fast physiological processes in the biological tissue. However, the high scanning ratecauses proportional decrease of the detector exposure time, resulting in a reduction of the…
  • Automatic diagnosis of melanoma using machine learning methods on a spectroscopic system

    Lin Li
    12 Oct 2014 | 5:00 pm
    Background: Early and accurate diagnosis of melanoma, the deadliest type of skin cancer, has the potential to reduce morbidity and mortality rate. However, early diagnosis of melanoma is not trivial even for experienced dermatologists, as it needs sampling and laboratory tests which can be extremely complex and subjective. The accuracy of clinical diagnosis of melanoma is also an issue especially in distinguishing between melanoma and mole. To solve these problems, this paper presents an approach that makes non-subjective judgements based on quantitative measures for automatic diagnosis of…
  • 3D facial landmarks: Inter-operator variability of manual annotation

    Jens Fagertun
    10 Oct 2014 | 5:00 pm
    Background: Manual annotation of landmarks is a known source of variance, which exist in all fields of medical imaging, influencing the accuracy and interpretation of the results. However, the variability of human facial landmarks is only sparsely addressed in the current literature as opposed to e.g. the research fields of orthodontics and cephalometrics. We present a full facial 3D annotation procedure and a sparse set of manually annotated landmarks, in effort to reduce operator time and minimize the variance.MethodFacial scans from 36 voluntary unrelated blood donors from the Danish Blood…

  • Determinants of clinical improvement after surgical replacement or transcatheter aortic valve implantation for isolated aortic stenosis

    Cristina Gavina
    5 Oct 2014 | 5:00 pm
    Background: Transcatheter aortic valve implantation (TAVI) is an alternative to surgical aortic valve replacement (SAVR) in patients with aortic stenosis (AS) and high surgical risk. Hemodynamic performance after TAVI is superior, but the impact of reverse remodeling on clinical improvement is controversial. We aim to address the differences in hemodynamic changes between SAVR and TAVI, and its correlation with LV remodeling and clinical improvement at 6 months follow-up. Methods: Forty-two patients treated by TAVI were compared with 45 SAVR patients with a stented bioprosthesis. Clinical, 2D…
  • Diastolic wall strain: a simple marker of abnormal cardiac mechanics

    Senthil Selvaraj
    2 Oct 2014 | 5:00 pm
    Background: Diastolic wall strain (DWS), defined using posterior wall thickness (PWT) measurements from standard echocardiographic images (DWS = [PWT(systole)-PWT(diastole)]/PWT(systole)), has been proposed as a marker of left ventricular (LV) diastolic stiffness. However, the equation for DWS is closely related to systolic radial strain, and whether DWS is associated with abnormal cardiac mechanics (reduced systolic strains and diastolic tissue velocities) is unknown. We sought to determine the relationship between DWS and systolic and diastolic cardiac mechanics. Methods: We calculated…
  • Carotid artery intima-media thickness is closely related to impaired left ventricular function in patients with coronary artery disease: a single-centre, blinded, non-randomized study

    Kristin Evensen
    28 Sep 2014 | 5:00 pm
    Background: Atherosclerosis is the underlying cause of the majority of myocardial infarctions and ischemic strokes. Carotid intima-media thickness (IMT) is a surrogate measure of atherosclerotic cardiovascular disease. Left ventricular (LV) function can be accurately assessed by 2D speckle-tracking strain echocardiography (2D-STE). The aim of this study was to assess the relationship between carotid IMT and LV dysfunction assessed by strain echocardiography in patients with coronary artery disease (CAD). Methods: Thirty-one patients with symptoms of CAD were examined with coronary…
  • Tissue Doppler, Strain and Strain Rate in ischemic heart disease ¿How I do it¿

    Razvan Mada
    17 Sep 2014 | 5:00 pm
    Echocardiography is the standard method for assessing myocardial function in patients with ischemic heart disease. The acquisition and interpretation of echocardiographic images, however, remains a highly specialized task which often relies entirely on the subjective visual assessment of the reader and requires therefore, particular training and expertise. Myocardial deformation imaging allows quantifying myocardial function far beyond what can be done with sole visual assessment. It can improve the interpretation of regional dysfunction and offers sensitive markers of induced ischemia which…
  • In vivo assessment of arterial stiffness in the isoflurane anesthetized spontaneously hypertensive rat

    Eric Morgan
    16 Sep 2014 | 5:00 pm
    Background: Rodent models are increasingly used to study the development and progression of arterial stiffness. Both the non-invasive Doppler derived Pulse Wave Velocity (PWV) and the invasively determined arterial elastance index (EaI) have been used to assess arterial stiffness in rats and mice, but the need for anesthetic agents to make these in vivo estimates may limit their utility. Thus, we sought to determine: 1) if known differences in arterial stiffness in spontaneously hypertensive rats (SHR) are detectable by PWV and EaI measurements when made under isoflurane anesthesia, and 2) if…

  • The effects of antidepressant treatment on resting-state functional brain networks in patients with major depressive disorder

    Li Wang, Mingrui Xia, Ke Li, Yawei Zeng, Yunai Su, Wenji Dai, Qinge Zhang, Zhen Jin, Philip B. Mitchell, Xin Yu, Yong He, Tianmei Si
    20 Oct 2014 | 10:11 pm
    Abstract Although most knowledge regarding antidepressant effects is at the receptor level, the neurophysiological correlates of these neurochemical changes remain poorly understood. Such an understanding could benefit from elucidation of antidepressant effects at the level of neural circuits, which would be crucial in identifying biomarkers for monitoring treatment efficacy of antidepressants. In this study, we recruited 20 first-episode drug-naive major depressive disorder (MDD) patients and performed resting-state functional magnetic resonance imaging (MRI) scans before and after 8 weeks…
  • Development of brain systems for nonsymbolic numerosity and the relationship to formal math academic achievement

    Frank Haist, Jarnet H. Wazny, Elizabeth Toomarian, Maha Adamo
    18 Oct 2014 | 3:16 am
    Abstract A central question in cognitive and educational neuroscience is whether brain operations supporting nonlinguistic intuitive number sense (numerosity) predict individual acquisition and academic achievement for symbolic or “formal” math knowledge. Here, we conducted a developmental functional magnetic resonance imaging (MRI) study of nonsymbolic numerosity task performance in 44 participants including 14 school age children (6–12 years old), 14 adolescents (13–17 years old), and 16 adults and compared a brain activity measure of numerosity precision to scores from the…
  • Neural signatures of fairness-related normative decision making in the ultimate game: A coordinate-based meta-analysis

    Chunliang Feng, Yue-Jia Luo, Frank Krueger
    18 Oct 2014 | 3:16 am
    Abstract The willingness to incur personal costs to enforce prosocial norms represents a hallmark of human civilization. Although recent neuroscience studies have used the ultimatum game to understand the neuropsychological mechanisms that underlie the enforcement of fairness norms; however, a precise characterization of the neural systems underlying fairness-related norm enforcement remains elusive. In this study, we used a coordinate-based meta-analysis on functional magnetic resonance imaging (fMRI) studies using the ultimatum game with the goal to provide an additional level of evidence…
  • The Mona Lisa effect: Neural correlates of centered and off-centered gaze

    Evgenia Boyarskaya, Alexandra Sebastian, Thomas Bauermann, Heiko Hecht, Oliver Tüscher
    18 Oct 2014 | 3:16 am
    Abstract The Mona Lisa effect describes the phenomenon when the eyes of a portrait appear to look at the observer regardless of the observer's position. Recently, the metaphor of a cone of gaze has been proposed to describe the range of gaze directions within which a person feels looked at. The width of the gaze cone is about five degrees of visual angle to either side of a given gaze direction. We used functional magnetic resonance imaging to investigate how the brain regions involved in gaze direction discrimination would differ between centered and decentered presentation positions of a…

    16 Oct 2014 | 10:10 am
    Abstract Resting-state studies conducted with stroke patients are scarce. The study of brain activity and connectivity at rest provides a unique opportunity for the investigation of brain rewiring after stroke and plasticity changes. This study sought to identify dynamic changes in the functional organization of the default mode network (DMN) of stroke patients at three months after stroke. Eleven patients (eight male and three female; age range: 48–72) with right cortical and subcortical ischemic infarctions and 17 controls (eleven males and six females; age range: 57–69) were assessed…

  • Can combined intracavitary/interstitial approach be an alternative to interstitial brachytherapy with the Martinez Universal Perineal Interstitial Template (MUPIT) in computed tomography-guided adaptive brachytherapy for bulky and/or irregularly shaped gynecological tumors?

    Takahiro Oike
    15 Oct 2014 | 5:00 pm
    Background: Interstitial brachytherapy (ISBT) is an optional treatment for locally advanced gynecological tumours for which conventional intracavitary brachytherapy (ICBT) would result in suboptimal dose coverage. However, ISBT with Martinez Universal Perineal Interstitial Template (MUPIT), in which ~10-20 needles are usually applied, is more time-consuming and labor-intensive than ICBT alone, making it a burden on both practitioners and patients. Therefore, here we investigated the applicability of a combined intracavitary/interstitial (IC/IS) approach in image-guided adaptive brachytherapy…

  • Why is Tc99m prefered for nuclear scan?

    Sumer Sethi
    16 Oct 2014 | 7:50 am
    Technetium- 99m  (metastable isomer) is the most frequently used radionuclide in nuclear medicine today. Its parent nuclide, molybdenum-99 (99Mo), can be produced in either a reactor or a cyclotron. 99Mo has a half-life of 66 h and therefore 99Mo/99mTc generators can conveniently be supplied weekly to nuclear medicine departments, providing a fresh daily supply of the radionuclide. The 6-h half-life of 99mTc is sufficiently long for most imaging applications and its 140-keV gamma radiation has reasonable tissue penetration but can still be easily collimatedFrom Sumer's Radiology Site…
