  • The sonographic “coffee bean” sign helps distinguish an axillary neurofibroma from a lymphadenopathy

    Journal of Clinical Ultrasound
    Sung Eun Song, Bo Kyoung Seo, Jung-Woo Choi, Gil-Soo Son, Kyu Ran Cho, Baek Hyun Kim
    21 Apr 2013 | 11:57 pm
    ABSTRACT Axillary masses may represent various soft tissue tumors or lymphadenopathy. Neurofibromas are benign peripheral nerve sheath tumors and, while they are very uncommon, it is important to remember that neurogenic tumors arising from brachial plexus can develop in the axilla. We describe an axillary neurofibroma arising from the brachial plexus that presented with a “coffee bean sign” on sonography that distinguished it from axillary lymphadenopathy. © 2013 Wiley Periodicals, Inc.

  • Radiographic Alternative for Opening Joint Spaces

    Topics in Radiography
    Jeremy Enfinger
    21 Apr 2013 | 9:29 pm
    We all know the basics of opening joint spaces on our radiographs.  Keep the joint space opening perpendicular to the image receptor while aligning the central ray directly to the joint.  No problem... x-ray 101 right?  But what about those joint spaces like wrists and ankles?  You know, the ones where some of the radiologists say "you should have gotten more of the tibia (or forearm)!"  Sometimes it's good to include a little extra - especially if your radiologists prefer it when there is obvious deformity. The problem lies within x-ray beam geometry.  I was…

  • Can YouTube be effective in radiology education?

    Andrew Dixon
    30 Mar 2013 | 6:00 pm
    We've all heard of YouTube and chances are you have watched more than a few videos on the site over the years. But what is relatively unknown is whether YouTube is an effective and desirable location for online radiology education. Six months ago, and with the collaborative backing of Radiopaedia.org, I launched ‘Radiology Channel’ as an experimental project to try and answer this question. With 18 video tutorials under our belt, more than 26,000 video views and 1,300 subscribers, the early results seem positive. But it’s now time to dig a little deeper. As part of our planned…

  • Clinical and imaging features of male breast disease, with pathological correlation: A pictorial essay

    Angeline Mei Lian Ng, Deepthi Dissanayake, Cecily Metcalf, Elizabeth Wylie
    16 May 2013 | 4:04 am
    Summary The majority of male breast diseases are benign. The most common is gynaecomastia. Although it is rare, the most critical diagnosis is a malignancy. Radiologists are generally less familiar with breast disease in males compared with females. This pictorial review will highlight the ultrasonographic, mammographic and pathological features of a spectrum of benign and malignant male breast diseases. This includes gynaecomastia, fat necrosis, lipoma, epidermoid cyst, subareolar abscess, chronic inflammation, melanoma and ductal carcinoma.

    Maurícia Vinhas
    30 Apr 2013 | 5:00 pm
    Background: In the recent years, the use of Doppler-echocardiography has become a standard non-invasive technique in the analysis of cardiac malformations in genetically modified mice. Therefore, normal values have to be established for the most commonly used inbred strains in whose genetic background those mutations are generated. Here we provide reference values for transthoracic echocardiography measurements in juvenile (3 weeks) and adult (8 weeks) 129/Sv mice. Methods: Echocardiographic measurements were performed using B-mode, M-mode and Doppler-mode in 15 juvenile (3 weeks) and 15…

  • Gene therapy for cardiovascular disease mediated by ultrasound and microbubbles

    Zhi-Yi Chen
    16 Apr 2013 | 5:00 pm
    Gene therapy provides an efficient approach for treatment of cardiovascular disease. To realize the therapeutic effect, both efficient delivery to the target cells and sustained expression of transgenes are required. Ultrasound targeted microbubble destruction (UTMD) technique has become a potential strategy for target-specific gene and drug delivery. When gene-loaded microbubble is injected, the ultrasound-mediated microbubble destruction may spew the transported gene to the targeted cells or organ. Meanwhile, high amplitude oscillations of microbubbles increase the permeability of capillary…

  • The true cost of cardiovascular imaging: focusing on downstream, indirect, and environmental costs

    To develop a more realistic assessment of costs, herein named “true” costs, the extra-cancer from medical radiation, environmental damage from imaging paraphernalia and radioactive wastes must be included as long-term costs from imaging examinations. It is urgent to define the “true” costs across imaging modalities as it interferes on physicians’ decision to request an exam and on research projects such as cost-effectiveness analysis. Cardiology is the specialty that most will benefit from the outcome as cardiovascular exams represent almost 30% of the total exams acquired annually…

  • The functional neuroanatomy of male psychosexual and physiosexual arousal: A quantitative meta-analysis

    Timm B. Poeppl, Berthold Langguth, Angela R. Laird, Simon B. Eickhoff
    14 May 2013 | 4:50 am
    Abstract Reproductive behavior is mandatory for conservation of species and mediated by a state of sexual arousal (SA), involving both complex mental processes and bodily reactions. An early neurobehavioral model of SA proposes cognitive, emotional, motivational, and autonomic components. In a comprehensive quantitative meta-analysis on previous neuroimaging findings, we provide here evidence for distinct brain networks underlying psychosexual and physiosexual arousal. Psychosexual (i.e., mental sexual) arousal recruits brain areas crucial for cognitive evaluation, top-down modulation of…

  • Functional MRI of cerebellar activity during eyeblink classical conditioning in children and adults

    Abstract This study characterized human cerebellar activity during eyeblink classical conditioning (EBC) in children and adults using functional magnetic resonance imaging (fMRI). During fMRI, participants were administered delay conditioning trials, in which the conditioned stimulus (a tone) precedes, overlaps, and coterminates with the unconditioned stimulus (a corneal airpuff). Behavioral eyeblink responses and brain activation were measured concurrently during two phases: pseudoconditioning, involving presentations of tone alone and airpuff alone, and conditioning, during which the tone…

  • Top-down and bottom-up influences on the left ventral occipito-temporal cortex during visual word recognition: An analysis of effective connectivity

    Matthias Schurz, Martin Kronbichler, Julia Crone, Fabio Richlan, Johannes Klackl, Heinz Wimmer
    14 May 2013 | 4:34 am
    Abstract The functional role of the left ventral occipito-temporal cortex (vOT) in visual word processing has been studied extensively. A prominent observation is higher activation for unfamiliar but pronounceable letter strings compared to regular words in this region. Some functional accounts have interpreted this finding as driven by top-down influences (e.g., Dehaene and Cohen [ 2011]: Trends Cogn Sci 15:254–262; Price and Devlin [ 2011]: Trends Cogn Sci 15:246–253), while others have suggested a difference in bottom-up processing (e.g., Glezer et al. [ 2009]: Neuron 62:199–204;…

  • Surprisingly correct: Unexpectedness of observed actions activates the medial prefrontal cortex

    Anne-Marike Schiffer, Kim H. Krause, Ricarda I. Schubotz
    14 May 2013 | 4:34 am
    Abstract Not only committing errors, but also observing errors has been shown to activate the dorsal medial prefrontal cortex, particularly BA 8 and adjacent rostral cingulate zone (RCZ). Currently, there is a debate on whether this activity reflects a response to the incorrectness of the committed action or to its unexpectedness. This article reports two studies investigating whether activity in BA 8/RCZ is due to the unexpectedness of observed errors or the incorrectness of the specific observed action.

    Federica Giambattistelli, Leo Tomasevic, Giovanni Pellegrino, Camillo Porcaro, Jean Marc Melgari, Paolo Maria Rossini, Franca Tecchio
    14 May 2013 | 4:34 am
    Abstract Brain effective connectivity can be tracked by cerebral recruitments evoked by transcranial magnetic stimulation (TMS), as measured by simultaneous electroencephalography (TMS-EEG). When TMS is targeting the primary motor area, motor evoked potentials (MEPs) can be collected from the “target” muscles. The aim of this study was to measure whether or not effective brain connectivity changes with the excitability level of the corticospinal motor pathway (CSMP) as parameterized by MEP amplitude. After averaging two subgroups of EEG-evoked responses corresponding to high and low MEP…

    M. Venturini, G. Querques, S. Margari, G. Agostini, M. Colombo, R. Caldara, C. Socci, F. De Cobelli, A. Del Maschio
    9 May 2013 | 3:36 am
    ABSTRACT Atherosclerotic renal artery stenosis is a frequent cause of arterial hypertension and/or allograft dysfunction after kidney transplantation and is usually located at the iliac artery anastomosis. Fibromuscular dysplasia is a less frequent, nonatherosclerotic, vascular disease, inducing stenosis at the proximal/mid-distal part of the renal artery. We report the case of a 44-year-old woman, in whom serum creatinine concentration increased and arterial hypertension developed 3 months after renal transplantation. Color Doppler ultrasonography showed a low arterial resistance index and…

  • The sonographic “coffee bean” sign helps distinguish an axillary neurofibroma from a lymphadenopathy

    Sung Eun Song, Bo Kyoung Seo, Jung-Woo Choi, Gil-Soo Son, Kyu Ran Cho, Baek Hyun Kim
    21 Apr 2013 | 11:57 pm
    ABSTRACT Axillary masses may represent various soft tissue tumors or lymphadenopathy. Neurofibromas are benign peripheral nerve sheath tumors and, while they are very uncommon, it is important to remember that neurogenic tumors arising from brachial plexus can develop in the axilla. We describe an axillary neurofibroma arising from the brachial plexus that presented with a “coffee bean sign” on sonography that distinguished it from axillary lymphadenopathy. © 2013 Wiley Periodicals, Inc.

  • SNPs in genes implicated in radiation response are associated with radiotoxicity and evoke roles as predictive and prognostic biomarkers

    Ghazi Alsbeih
    21 May 2013 | 5:00 pm
    Background: Biomarkers are needed to individualize cancer radiation treatment. Therefore, we have investigated the association between various risk factors, including single nucleotide polymorphisms (SNPs) in candidate genes and late complications to radiotherapy in our nasopharyngeal cancer patients. Methods: A cohort of 155 patients was included. Normal tissue fibrosis was scored using RTOG/EORTC grading system. A total of 45 SNPs in 11 candidate genes (ATM, XRCC1, XRCC3, XRCC4, XRCC5, PRKDC, LIG4, TP53, HDM2, CDKN1A, TGFB1) were genotyped by direct genomic DNA sequencing. Patients with…

  • Breast Screening: hardly a pleasure trip but the consequences of not having it could be far more unpleasant

    Sophia Moseley
    29 Apr 2013 | 5:46 am
    When I received a letter from the Somerset Breast Screening Centre, the alarm bells started to ring. Why had they contacted me? What did they know that I didn’t? Having had the X-ray, would I go through days of mentally debilitating torture whilst I waited to hear the worst? I cannot deny I do have a tendency for the dramatics – it goes with the territory of being a writer – and when I calmed down I realised it was probably part of the Government’s drive toward preventative health care as the letter said they are now ’inviting’ women under the usual…

  • Control freak

    27 Apr 2013 | 4:53 pm
    All the events in my life led to me wanting to control the outcome of every action I ever do or is being done around me. Though I have to say I’m kind of a hectic, last minute control freak, because I like doing everything myself and the workload is for at least 4 people, even if I work for two and three, I never get things done till the deadline. So I set earlier deadlines. Crazy right? The true wrong part is that life gave me traumas, so I ended up defending myself against it more and more, but my many sides let me miss the important parts. Every time I’ve let my guard down I…

    I don’t know what is wrong with me. Right now I have two sides living inside myself, at the same time, thinking at the same time. I have two sets of thoughts on every subject and two set of actions that i can do and they are always at the opposite sides. So today I wanted to go out with people, but I hated people and I wanted to be alone, but resented my loneliness  I wanted someone to pick me up, but I told him not to because I wanted, but also didn’t wanted to go out. I thought it would be too hard to leave my house and that it would be comfortable to stay in, but it…

    It may take ages to reach to this point in India, but if i was ever made an examiner in a Radiology exam, i would rather look to pass a candidate with more day to day skills than the one who has mugged up all the data.  The kind of exam i would to conduct would be an Open Book, Open Web format, which would be more in line with our actual day to practise. Candidate i believe should have fair search skills and should know where to look for. Of course time limits should be strict so that the radiologists understand the value of turn around times and more marks would on the reporting…

Pay-package wise there is hardly any difference in the private sector.  Usually, in the first go, people prefer: Delhi, Mumbai and Hyderabad for DNB and also, Bangalore & Pune. Usual places preferred in Delhi are Saftardjung, Gangaram,…

  • CR Quality Control Summary

    Jeremy Enfinger
    11 May 2013 | 10:11 am
    A consistent quality control program goes a long way toward maintaining a high standard of image quality within your radiology department.  The tests posted within this series are not all-inclusive for every CR system, but may provide as a good start for the beginning stages of any QC program.  Variations may occur if your department utilizes a hard-copy laser printer and/or measurement tools at the QC station (or to include the radiologists' work station). As a general rule of thumb, most CR vendors recommend designating one person as the quality control technologist.  Other…

    This test evaluates the CR reader’s erasure function and should be performed semi-annually.  Each exposed image plate should be adequately erased during the processing cycle to prevent a residual image on the next image. Procedure: Erase your dedicated test IP Place a lead apron on the floor of your x-ray room (use same room that baseline image was performed in) Place test IP on lead apron Place phantom on cassette (same orientation as baseline image) Raise the x-ray tube to maximum height, center, and open collimation about 1" past edges of test IP Expose the phantom at using twice…

  • Shape Distortion

    One of the most fun courses I have taken and taught is exposure principles.  This course typically introduces students to different types of distortion that can occur on the radiograph.  Size distortion, otherwise known as simple distortion or magnification, occurs when OID is increased.  The other type of distortion, shape distortion, can be broken down into two main categories; foreshortening and elongation. Foreshortening is when the radiographic image measures shorter in one dimension than the actual object being radiographed.  The only way this can happen is if the…

    We all know the basics of opening joint spaces on our radiographs.  Keep the joint space opening perpendicular to the image receptor while aligning the central ray directly to the joint.  No problem... x-ray 101 right?  But what about those joint spaces like wrists and ankles?  You know, the ones where some of the radiologists say "you should have gotten more of the tibia (or forearm)!"  Sometimes it's good to include a little extra - especially if your radiologists prefer it when there is obvious deformity. The problem lies within x-ray beam geometry.  I was…
