  • 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…

  • 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…

  • 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…
  • Statistical mapping of metabolites in the medial wall of the brain: A proton echo planar spectroscopic imaging study

    David M. Niddam, Shang-Yueh Tsai, Yi-Ru Lin
    22 Oct 2014 | 10:12 pm
    Abstract With magnetic resonance spectroscopic imaging (MRSI), it is possible to simultaneously map distributions of several brain metabolites with relatively good spatial resolution in a short time. Although other functional imaging modalities have taken advantage of population-based inferences using spatially extended statistics, this approach remains little utilized for MRSI. In this study, statistical nonparametric mapping (SnPM) was applied to two-dimensional MRSI data from the medial walls of the human brain to assess the effect of normal aging on metabolite concentrations. The effects…
  • The DTI connectivity of the human claustrum

    Carinna M. Torgerson, Andrei Irimia, S. Y. Matthew Goh, John Darrell Van Horn
    22 Oct 2014 | 10:12 pm
    Abstract The origin, structure, and function of the claustrum, as well as its role in neural computation, have remained a mystery since its discovery in the 17th century. Assessing the in vivo connectivity of the claustrum may bring forth useful insights with relevance to model the overall functionality of the claustrum itself. Using structural and diffusion tensor neuroimaging in N = 100 healthy subjects, we found that the claustrum has the highest connectivity in the brain by regional volume. Network theoretical analyses revealed that (a) the claustrum is a primary contributor to global…

  • GTV-based prescription in SBRT for lung lesions using advanced dose calculation algorithms

    Thomas Lacornerie
    15 Oct 2014 | 5:00 pm
    Background: The aim of current study was to investigate the way dose is prescribed to lung lesions during SBRT using advanced dose calculation algorithms that take into account electron transport (type B algorithms). As type A algorithms do not take into account secondary electron transport, they overestimate the dose to lung lesions. Type B algorithms are more accurate but still no consensus is reached regarding dose prescription. The positive clinical results obtained using type A algorithms should be used as a starting point. Methods: In current work a dose-calculation experiment is…

  • Too much to do, too little time-problem or paradox

    Sumer Sethi
    24 Oct 2014 | 8:54 am
    People keep complaining about lack of time and they keep saying they are busy. At times I have seen people who say they are too busy even to talk on phone.Well my dear friends it is never about time, it is always about priorities.If you really want to do something you will somehow manage time. We all have ‘less and more time’ with us all the time, and we keep swinging between the two sides depending on our priorities. Why is this so important to know, because you might be spending your precious “time” on valueless things and if you don’t prioritize, you end up being busy with very…
