  • Performance of two neutral oral contrast agents in CT enterography

    Jessica Wong, Mark Roger, Helen Moore
    27 Oct 2014 | 1:11 am
    Abstract IntroductionThis study compares the performance of two neutral oral contrast agents in CT enterography (CTE). Mannitol 2.5%, an oral osmotic agent, is compared with psyllium fibre (Metamucil). Both these agents are commonly used, but to our knowledge, they have not been compared in CTE. MethodsCTE data were collected from 25 consecutive studies for both mannitol and psyllium fibre between 2011 and 2013. All images were reviewed by two radiologists and one registrar blinded to the oral contrast used. Each quadrant was assessed for maximum distension, proportion of bowel loops…

  • Quality indicators for prostate radiotherapy: Are patients disadvantaged by receiving treatment in a ‘generalist’ centre?

    Amanda R Freeman, Daniel E Roos, Laurence Kim
    27 Oct 2014 | 1:11 am
    Abstract IntroductionThe purpose of this retrospective review was to evaluate concordance with evidence-based quality indicator guidelines for prostate cancer patients treated radically in a ‘generalist’ (as distinct from ‘sub-specialist’) centre. We were concerned that the quality of treatment may be lower in a generalist centre. If so, the findings could have relevance for many radiotherapy departments that treat prostate cancer. MethodsTwo hundred fifteen consecutive patients received external beam radiotherapy (EBRT) and/or brachytherapy between 1.10.11 and 30.9.12. Treatment was…
  • Percutaneous microwave ablation for early-stage non-small cell lung cancer (NSCLC) in the elderly: A promising outlook

    Christian Acksteiner, Karin Steinke

  • Myofibre segmentation in H&E stained adult skeletal muscle images using coherence-enhancing diffusion filtering

    Harry Strange
    28 Oct 2014 | 5:00 pm
    Background: The correct segmentation of myofibres in histological muscle biopsy images is a critical step in the automatic analysis process. Errors occurring as a result of incorrect segmentations have a compounding effect on latter morphometric analysis and as such it is vital that the fibres are correctly segmented. This paper presents a new automatic approach to myofibre segmentation in H&E stained adult skeletal muscle images that is based on Coherence-Enhancing Diffusion filtering. Methods: The procedure can be broadly divided into four steps: 1) pre-processing of the images to extract…
  • 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 the spatial 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 the OCT imaging speed by a factor of more than 100, which is important for retinal imaging where we wish to study fast physiological processes in the biological tissue. However, the high scanning rate causes 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…
  • Breakthrough reactions of iodinated and gadolinium contrast media after oral steroid premedication protocol

    Akiko Jingu
    5 Oct 2014 | 5:00 pm
    Background: Adverse reactions to iodinated and gadolinium contrast media are an important clinical issue. Although some guidelines have proposed oral steroid premedication protocols to prevent adverse reactions, some patients may have reactions to contrast media in spite of premedication (breakthrough reaction; BTR).The purpose of this study was to assess the frequency, type and severity of BTR when following an oral steroid premedication protocol. Methods: All iodinated and gadolinium contrast-enhanced radiologic examinations between August 2011 and February 2013 for which the premedication…

  • Cardiac calcium score on 2D echo: correlations with cardiac and coronary calcium at multi-detector computed tomography

    Nicola Gaibazzi
    27 Oct 2014 | 5:00 pm
    Background: To test the hypothesis that a semi-quantitative echocardiographic calcium score (eCS) significantly correlates with cardiac calcium measured by coronary computed tomography angiography (CCTA) and, secondarily, severe coronary artery calcifications and stenosis. Methods: This is a retrospective, observational study, conducted in a tertiary centre. eCS was compared with CCTA scores of non-coronary cardiac calcium (nCACS), coronary cardiac calcium (CACS) and number of diseased coronary vessels, in 141 subjects without known coronary artery disease (CAD), who underwent both…
  • Two and three dimensional echocardiography for pre-operative assessment of mitral valve regurgitation

    Nishath Quader
    24 Oct 2014 | 5:00 pm
    Mitral regurgitation may develop when the leaflets or any other portion of the apparatus becomes abnormal. As the repair techniques for mitral valve disease evolved, so has the need for detailed and accurate imaging of the mitral valve prior to surgery in order to better define the mechanism of valve dysfunction and the severity of regurgitation. In patients with significant mitral valve disease who require surgical intervention, multiplane transesophageal echocardiogram (TEE) is invaluable for surgical planning. However, a comprehensive TEE in a patient with complex mitral valve disease…
  • 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…

  • Transvenous Biopsy of Retroperitoneal Tumoral Masses: Value of Cone-Beam CT Guidance

    Geert Maleux, Gert De Hertogh, Matthias Lavens, Raymond Oyen
    31 Oct 2014 | 5:00 pm
    Solid retroperitoneal masses with indeterminate tissue characteristics are usually investigated by biopsy percutaneously under ultrasound (US) or computed tomography (CT) guidance. However, in cases of infrarenal, pericaval masses, safe access avoiding intervening structures such as colon, kidney, or major vessels may be difficult or even impossible. In these cases, a transvenous approach might be a reasonable alternative. To improve control of the transvenous approach and to avoid inadvertent passage of intervening organs, cone-beam CT guidance can be used.
  • Endovascular Treatment of Symptomatic Vestibular Aqueduct Dehiscence as a Result of Jugular Bulb Abnormalities

    Marie-Aude Thénint, Charlotte Barbier, Martin Hitier, Vincent Patron, Suzana Saleme, Patrick Courthéoux
    31 Oct 2014 | 5:00 pm
    A new endovascular treatment consisting of stent-assisted coil implantation is described for jugular bulb abnormalities causing symptomatic vestibular aqueduct dehiscence. Three patients presenting with vertigo associated with pulsatile tinnitus or hearing loss were treated. This technique cured the vertigo and pulsatile tinnitus in all patients and preserved normal cerebral venous drainage with no side effects.
  • Extraluminal Left Brachiocephalic Vein Superior Vena Cava (SVC) Confluence Reconstruction Using a Radiofrequency Wire to Treat SVC Syndrome

    Gajan Sivananthan, David W. Allen, Neil J. Halin
    31 Oct 2014 | 5:00 pm
    The technique of intraluminal crossing of a chronic central venous occlusion by using a radiofrequency (RF) wire has been previously described (1,2). In the present report, we describe a variation of this technique that uses an RF wire (Baylis, Montreal, Quebec, Canada) and a VIABAHN stent (W.L. Gore and Associates, Flagstaff, Arizona) to create a channel outside of an existing right brachiocephalic vein (BCV)/superior vena cava (SVC) stent crossing an occluded left BCV. This report met the criteria for institutional review board exemption.
  • Re: Double Coaxial Microcatheter Technique for Transarterial Aneurysm Sac Embolization of Type II Endoleaks after Endovascular Abdominal Aortic Repair

    Daniel M. Conroy, Anton J. Collins, Peter T. Kennedy
    31 Oct 2014 | 5:00 pm
    We read with interest the recent article by Hongo et al (1) describing their experience managing type II endoleaks using a double microcatheter technique to perform embolization. In their series, the authors found that 2 of 20 patients experienced transient lumbar pain. We wish to share our experience of a patient who sustained a more permanent complication from a similar technique.

  • Distributed neural representations of logical arguments in school-age children

    Romain Mathieu, James R. Booth, Jérôme Prado
    29 Oct 2014 | 11:54 pm
    Abstract Children's understanding of linear-order (e.g., Dan is taller than Lisa, Lisa is taller than Jess) and set-inclusion (i.e., All tulips are flowers, All flowers are plants) relationships is critical for the acquisition of deductive reasoning, that is, the ability to reach logically valid conclusions from given premises. Behavioral and neuroimaging studies in adults suggest processing differences between these relations: While arguments that involve linear-orders may be preferentially associated with spatial processing, arguments that involve set-inclusions may be preferentially…
  • Predictive distractor context facilitates attentional selection of high, but not intermediate and low, salience targets

    Thomas Töllner, Markus Conci, Hermann J. Müller
    28 Oct 2014 | 9:46 pm
    Abstract It is well established that we can focally attend to a specific region in visual space without shifting our eyes, so as to extract action-relevant sensory information from covertly attended locations. The underlying mechanisms that determine how fast we engage our attentional spotlight in visual-search scenarios, however, remain controversial. One dominant view advocated by perceptual decision-making models holds that the times taken for focal-attentional selection are mediated by an internal template that biases perceptual coding and selection decisions exclusively through…
  • Stimulus dependence of contralateral dominance in human auditory cortex

    Alexander Gutschalk, Iris Steinmann
    23 Oct 2014 | 10:24 pm
    Abstract The auditory system is often considered to show little contralateral dominance but physiological reports on the contralateral dominance of activity evoked by monaural sound vary widely. Here, we show that part of this variation is stimulus-dependent: blood oxygen level dependent (BOLD) responses to 32 s of monaurally presented unmodulated noise (UN) showed activation in contralateral auditory cortex (AC) and deactivation in ipsilateral AC compared to nonstimulus baseline. Slow amplitude-modulated (AM) noise evoked strong contralateral activation and minimal ipsilateral activation.
  • Increased functional connectivity between superior colliculus and brain regions implicated in bodily self-consciousness during the rubber hand illusion

    Isadora Olivé, Claus Tempelmann, Alain Berthoz, Hans-Joachim Heinze
    23 Oct 2014 | 10:23 pm
    Abstract Bodily self-consciousness refers to bodily processes operating at personal, peripersonal, and extrapersonal spatial dimensions. Although the neural underpinnings of representations of personal and peripersonal space associated with bodily self-consciousness were thoroughly investigated, relatively few is known about the neural underpinnings of representations of extrapersonal space relevant for bodily self-consciousness. In the search to unravel brain structures generating a representation of the extrapersonal space relevant for bodily self-consciousness, we developed a functional…
  • Reduced executive and default network functional connectivity in cigarette smokers

    Barbara J. Weiland, Amithrupa Sabbineni, Vince D. Calhoun, Robert C. Welsh, Kent E. Hutchison
    23 Oct 2014 | 10:22 pm
    Abstract Altered functional connectivity has been associated with acute and chronic nicotine use. Connectivity alterations, specifically in the right and left executive control networks (RECN/LECN) and the default mode network (DMN), may contribute to the addiction cycle. The objective of this study was to determine if executive control network (ECN) and DMN connectivity is different between non-smokers and smokers and whether reductions in connectivity are related to chronic cigarette use. The RECN, LECN, and DMN were identified in resting state functional magnetic resonance imaging data in…

  • Higher caseload improves cervical cancer survival in patients treated with brachytherapy

    Moon-Sing Lee
    25 Oct 2014 | 5:00 am
    ObjectivesIncreased caseload has been associated with better patient outcomes in many areas of health care, including high-risk surgery and cancer treatment.

    Known as the “Nanoparticle Platform,” the project is part of a wider effort inside Google to develop new technologies capable of improving healthcare.According to a report, Google is fashioning nanoparticles that combine a magnetic material with antibodies or proteins that can attach to and detect other molecules inside the body. The idea is that patients will swallow a pill that contains these particles, and after they enter the bloodstream—attempting to identify molecules that would indicate certain health problems—a wearable device could use their magnetic cores to gather them back…
  • The Test of “Time”

    As a kid I used to wonder why organizations and stores across the world write on their boards, tag lines like “Since 1831” or “since 1920”.  But, with running my own organizations both DAMS and TeleRad Providers I have  realized that  we actually improved, and added processes every year. We are actually not the same organization anymore, we have changed with time and we have evolved with evolving technologies and consumer needs. Now I have understood the value of organizations which have survived more than 100 years with changing customer base and mindset, have actually…
  • Organized Chaos

    25 Oct 2014 | 9:50 am
    Most people try very hard to make processes and workflow, hoping for a perfect organization with everything in place and no chaos. Most start ups feel that larger corporations are fully organized. What I have learnt is the fact that it is always a chaos in every organization, every effort to achieve a goal but the only ones who are able to direct the chaos towards a common goal, are able to do well. Hence my term for successful people and great organizations is organized chaos. At the ‘micro’ level you will observe chaos but at a ‘macro’ level you will find the ‘organized chaos’…
