    Mugikura, S., Kikuchi, H., Fujii, T., Murata, T., Takase, K., Mori, E., Marinkovic, S., Takahashi, S.
    15 Dec 2014 | 8:01 am
    BACKGROUND AND PURPOSE: During surgery to treat an aneurysm in the anterior communicating artery, injury to the subcallosal artery, a perforator of the anterior communicating artery, may lead to infarction that produces basal forebrain amnesia after surgery. Our purpose was to examine whether 3D MR imaging can detect subcallosal artery infarction in patients with amnesia after surgery for an anterior communicating artery aneurysm. MATERIALS AND METHODS: We evaluated 3D–T2-weighted MR images obtained a median of 4 months after treatment of anterior communicating artery aneurysm for the…
  • Susceptibility-Weighted MR Imaging: A Better Technique in the Detection of Capillary Telangiectasia Compared with T2* Gradient-Echo [BRAIN]

    Chaudhry, U. S., De Bruin, D. E., Policeni, B. A.
    15 Dec 2014 | 8:01 am
    BACKGROUND AND PURPOSE: Enhancing lesions on brain MR imaging can present a diagnostic quandary as both benign lesions such as brain capillary telangiectasia and pathologic lesions such as demyelination may appear similar. Stagnation of blood in low-flow venous channels of brain capillary telangiectasias results in susceptibility effect secondary to the increased local deoxyhemoglobin. Both T2* gradient-echo imaging and SWI were demonstrated as valuable in the diagnosis of brain capillary telangiectasia. Because SWI is more sensitive to susceptibility changes than gradient-echo, we aim to…

  • 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…

    Kumar Ramnarine
    7 Dec 2014 | 4:00 pm
    Background: Shear Wave Elastography (SWE) imaging is a novel ultrasound technique for quantifying tissue elasticity. Studies have demonstrated that SWE is able to differentiate between diseased and normal tissue in a wide range clinical applications. However its applicability to atherosclerotic carotid disease has not been established. The aim of this study was to assess the feasibility and potential clinical benefit of using SWE imaging for the assessment of carotid plaques. Methods: Eighty-one patients (mean age 76 years, 51 male) underwent greyscale and SWE imaging. Elasticity was…
  • Utility of carotid duplex ultrasonography in a general inner-city hospital

    Mihir Barvalia
    24 Nov 2014 | 4:00 pm
    Background: Carotid Duplex Ultrasonography (CDUS) is one of the non-invasive imaging modalities used to evaluate for carotid artery stenosis. However, it is often used in patients with coronary artery disease (CAD), peripheral artery disease (PAD), before heart surgery, syncope and non-specific neurological symptoms although its value is unclear. Our study aimed to further investigate the yield of CDUS in these conditions. Methods: A retrospective analysis was conducted on 827 consecutive carotid ultrasounds ordered between March 2013 and August 2013 at Newark Beth Israel Medical Center.

  • Echocardiographic assessment of ischemic mitral regurgitation

    David Dudzinski
    20 Nov 2014 | 4:00 pm
    Ischemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. Echocardiographic diagnosis and assessment of ischemic mitral regurgitation are critical to gauge its adverse effects on prognosis and to attempt to tailor rational treatment strategy. There is no single approach to the echocardiographic assessment of ischemic mitral regurgitation: standard echocardiographic measures of mitral regurgitation severity and of LV dysfunction are complemented by assessments of displacement of the papillary muscles and quantitative indices of mitral valve…

  • Sex differences in normal age trajectories of functional brain networks

    Dustin Scheinost, Emily S. Finn, Fuyuze Tokoglu, Xilin Shen, Xenophon Papademetris, Michelle Hampson, R. Todd Constable
    18 Dec 2014 | 8:30 pm
    Abstract Resting-state functional magnetic resonance image (rs-fMRI) is increasingly used to study functional brain networks. Nevertheless, variability in these networks due to factors such as sex and aging is not fully understood. This study explored sex differences in normal age trajectories of resting-state networks (RSNs) using a novel voxel-wise measure of functional connectivity, the intrinsic connectivity distribution (ICD). Males and females showed differential patterns of changing connectivity in large-scale RSNs during normal aging from early adulthood to late middle-age. In some…
  • Early integration of bilateral touch in the primary somatosensory cortex

    Luigi Tamè, Francesco Pavani, Christos Papadelis, Alessandro Farnè, Christoph Braun
    16 Dec 2014 | 8:44 pm
    Abstract Animal, as well as behavioural and neuroimaging studies in humans have documented integration of bilateral tactile information at the level of primary somatosensory cortex (SI). However, it is still debated whether integration in SI occurs early or late during tactile processing, and whether it is somatotopically organized. To address both the spatial and temporal aspects of bilateral tactile processing we used magnetoencephalography in a tactile repetition-suppression paradigm. We examined somatosensory evoked-responses produced by probe stimuli preceded by an adaptor, as a function…
  • Accessing orthographic representations from speech: The role of left ventral occipitotemporal cortex in spelling

    Philipp Ludersdorfer, Martin Kronbichler, Heinz Wimmer
    12 Dec 2014 | 4:20 pm
    Abstract The present fMRI study used a spelling task to investigate the hypothesis that the left ventral occipitotemporal cortex (vOT) hosts neuronal representations of whole written words. Such an orthographic word lexicon is posited by cognitive dual-route theories of reading and spelling. In the scanner, participants performed a spelling task in which they had to indicate if a visually presented letter is present in the written form of an auditorily presented word. The main experimental manipulation distinguished between an orthographic word spelling condition in which correct spelling…
  • Cerebellar white matter pathways are associated with reading skills in children and adolescents

    Katherine E. Travis, Yael Leitner, Heidi M. Feldman, Michal Ben-Shachar
    12 Dec 2014 | 4:20 pm
    Abstract Reading is a critical life skill in the modern world. The neural basis of reading incorporates a distributed network of cortical areas and their white matter connections. The cerebellum has also been implicated in reading and reading disabilities. However, little is known about the contribution of cerebellar white matter pathways to major component skills of reading. We used diffusion magnetic resonance imaging (dMRI) with tractography to identify the cerebellar peduncles in a group of 9- to 17-year-old children and adolescents born full term (FT, n = 19) or preterm (PT,…
  • Imaging distributed and massed repetitions of natural scenes: Spontaneous retrieval and maintenance

    Margaret M. Bradley, Vincent D. Costa, Vera Ferrari, Maurizio Codispoti, Jeffrey R. Fitzsimmons, Peter J. Lang
    12 Dec 2014 | 4:17 pm
    Abstract Repetitions that are distributed (spaced) across time prompt enhancement of a memory-related event-related potential, compared to when repetitions are massed (contiguous). Here, we used fMRI to investigate neural enhancement and suppression effects during free viewing of natural scenes that were either novel or repeated four times with massed or distributed repetitions. Distributed repetition was uniquely associated with a repetition enhancement effect in a bilateral posterior parietal cluster that included the precuneus and posterior cingulate and which has previously been…

    Neeharika Sinha, Gizem Cifter, Erno Sajo, Rajiv Kumar, Srinivas Sridhar, Paul L. Nguyen, Robert A. Cormack, G. Mike Makrigiorgos, Wilfred Ngwa
    4 Dec 2014 | 4:00 pm
    Recent studies show promise that administering gold nanoparticles (GNP) to tumor cells during brachytherapy could significantly enhance radiation damage to the tumor. A new strategy proposed for sustained administration of the GNP in prostate tumors is to load them into routinely used brachytherapy spacers for customizable in situ release after implantation. This in silico study investigated the intratumor biodistribution and corresponding dose enhancement over time due to GNP released from such GNP-loaded brachytherapy spacers (GBS).

  • Baseline neutrophil-lymphocyte ratio (¿2.8) as a prognostic factor for patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiation

    Lijun Shen
    18 Dec 2014 | 4:00 am
    Background: The neutrophil-lymphocyte ratio (NLR) has been proposed as an indicator of systemic inflammatory response and may predict the clinical outcome in some cancers, such as head and neck cancer and gastric cancer. However, the value of this ratio is variable in different cancers. Studies of the relationship between NLR and both survival and response to chemoradiation have been limited with respect to locally advanced rectal cancer.Methods and materialsFrom 2006 to 2011, 199 consecutive locally advanced rectal cancer patients who were treated with neoadjuvant chemoradiation in the…

  • Endothelial perturbations and therapeutic strategies in normal tissue radiation damage

    Elina Korpela
    18 Dec 2014 | 4:00 am
    Most cancer patients are treated with radiotherapy, but the treatment can also damage the surrounding normal tissue. Radiotherapy side-effects diminish patients? quality of life, yet effective biological interventions for normal tissue damage are lacking. Protecting microvascular endothelial cells from the effects of irradiation is emerging as a targeted damage-reduction strategy. We illustrate the concept of the microvasculature as a mediator of overall normal tissue radiation toxicity through cell death, vascular inflammation (hemodynamic and molecular changes) and functional capacity.

    Example: Whenever I am travelling, most of the domestic airlines I see them selling trashy products and hardly anyone is interested in buying. One day I asked the crew that you don't provide any newspaper on flight (low cost airlines) if instead of carrying the load of these products (which hardly sell) if you could just sell newspapers at the beginning of flight at say Rs 20 even Rs 50 or 100 almost everyone on board will buy one as we have almost nothing to do for the journey, you add value to our journey and your airlines makes more money (imagine selling at 25 times the cost price).

    Although we all have been taught about courage in school, but what exactly is courage in our day to day life or is it just the soldiers in the war or warriors who can exhibit such feeling. To me courage is the choosing to go forward when odds are against you and you have a choice to give up. We all get the option to be courageous with our choices or give up. Trust me, everybody feels the fear of failure, everyone feels like giving up at sometime, but the winners chose to go forward.Sometimes even staying put needs courage and moving forward needs conviction in your dreams. That's the secret…
