    BACKGROUND AND PURPOSE: The risk factors of early hemorrhagic complications after endovascular coiling are not well-known. We identified the factors affecting early hemorrhagic complications, defined as any expansion or appearance of hemorrhage shown by head CT in the initial 48 hours after coiling. MATERIALS AND METHODS: We retrospectively reviewed a series of 93 patients who underwent coiling for a ruptured saccular aneurysm between 2006 and 2012 at our hospital. RESULTS: Five patients showed early hemorrhagic complications, and all involved an expansion of the existing intracerebral…
  • PET Approaches for Diagnosis of Dementia [REVIEW ARTICLES]

    Ishii, K.
    14 Nov 2014 | 8:01 am
    SUMMARY: There is increasing use of neuroimaging modalities, including PET, for diagnosing dementia. For example, FDG-PET demonstrates hypometabolic regions in the posterior cingulate gyri, precuneus, and parietotemporal association cortices, while amyloid PET indicates amyloid deposition in Alzheimer disease and mild cognitive impairment due to Alzheimer disease. Furthermore, the use of combination PET with structural MR imaging can improve the diagnostic accuracy of dementia. In other neurodegenerative dementias, each disease exhibits a specific metabolic reduction pattern. In dementia with…

  • Four-dimensional computed tomography and detection of dynamic capitate subluxation

    Stephen E Repse, Benjamin Amis, John M Troupis
    20 Nov 2014 | 1:15 am
    Summary Midcarpal instability syndrome is often misdiagnosed, leading to delayed recognition, treatment and possibly poor clinical outcome. Four-dimensional computed tomography (4D CT) has previously proved useful in assessment of the acromioclavicular joint and wrist motion, allowing clinicians and radiologists to gain an understanding of abnormalities in function as well as morphology, which often contribute to patient symptoms. We present the case of a 25-year-old male with no history of trauma who presents with several months of a right wrist clunk on both passive and active (load…
  • Bipartite lunate incidentally noted on radiographs obtained for skeletal age estimation: A report of two cases

    Muhammad Awais, Yousuf Husen, Abdul Rehman
    20 Nov 2014 | 1:15 am
    Summary Bipartite lunate is a rare congenital anomaly of carpal bones. We present a report of two cases where children referred for determination of skeletal age were incidentally found to have bipartite lunate. In both cases, radiographic appearance of lunate could have been mistaken for secondary centres of ossification in other carpal bones. It is imperative for all radiologists to be aware of this rare congenital anomaly in order to avoid pitfalls in clinical diagnosis.

  • Prevalence of incidental or unexpected findings on low-dose CT performed during routine SPECT/CT nuclear medicine studies

    Kelvin Kwok-Ho Yap, Ganesh Ramaseshan, Tom Sutherland, Raymond Shafik-Eid, Kim Taubman, Stephen Schlicht
    20 Nov 2014 | 1:14 am
    Abstract IntroductionIn nuclear medicine, single-photon-emission computed tomography (SPECT) is often combined with ‘simultaneous’ low-dose CT (LDCT) to provide complementary anatomical and functional correlation. As a consequence, numerous incidental and unexpected findings may be detected on LDCT. Recognition of these findings and appropriate determination of their relevance can add to the utility of SPECT/CT. We aimed to evaluate the prevalence and categorise the relevance of incidental and unexpected findings on LDCT scans performed as part of routine SPECT/CT studies. MethodsAll…
  • 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…

  • 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…
  • Preoperative left ventricular ejection fraction and left atrium reverse remodeling after mitral regurgitation surgery

    Lucia Machado
    5 Nov 2014 | 4:00 pm
    Background: Left atrium enlargement has been associated with cardiac events in patients with mitral regurgitation (MR). Left atrium reverse remodeling (LARR) occur after surgical correction of MR, but the preoperative predictors of this phenomenon are not well known. It is therefore important to identify preoperative predictors for postoperative LARR. Methods: We enrolled 62 patients with chronic severe MR (prolapse or flail leaflet) who underwent successful mitral valve surgery (repair or replacement); all with pre- and postoperative echocardiography. LARR was defined as a reduction in left…
  • Estimation of cardiac output and pulmonary vascular resistance by contrast echocardiography transit time measurement: a prospective pilot study

    Brian Choi
    30 Oct 2014 | 5:00 pm
    Background: Studies with other imaging modalities have demonstrated a relationship between contrast transit and cardiac output (CO) and pulmonary vascular resistance (PVR). We tested the hypothesis that the transit time during contrast echocardiography could accurately estimate both CO and PVR compared to right heart catheterization (RHC). Methods: 27 patients scheduled for RHC had 2D-echocardiogram immediately prior to RHC. 3 ml of DEFINITY contrast followed by a 10 ml saline flush was injected, and a multi-cycle echo clip was acquired from the beginning of injection to opacification of…

  • Distinct anatomical correlates of discriminability and criterion setting in verbal recognition memory revealed by lesion-symptom mapping

    J. Matthijs Biesbroek, Martine J.E. van Zandvoort, L. Jaap Kappelle, Linda Schoo, Hugo J. Kuijf, Birgitta K. Velthuis, Geert Jan Biessels, Albert Postma,
    25 Nov 2014 | 8:43 pm
    Abstract Recognition memory, that is, the ability to judge whether an item has been previously encountered in a particular context, depends on two factors: discriminability and criterion setting. Discriminability draws on memory processes while criterion setting (i.e., the application of a threshold resulting in a yes/no response) is regarded as a process of cognitive control. Discriminability and criterion setting are assumed to draw on distinct anatomical structures, but definite evidence for this assumption is lacking. We applied voxel-based and region of interest-based lesion-symptom…
  • Dopaminergic basis for impairments in functional connectivity across subdivisions of the striatum in Parkinson's disease

    Peter T. Bell, Moran Gilat, Claire O'Callaghan, David A. Copland, Michael J. Frank, Simon J.G. Lewis, James M. Shine
    25 Nov 2014 | 8:43 pm
    Abstract The pathological hallmark of Parkinson's disease is the degeneration of dopaminergic nigrostriatal neurons, leading to depletion of striatal dopamine. Recent neuroanatomical work has identified pathways for communication across striatal subdivisions, suggesting that the striatum provides a platform for integration of information across parallel corticostriatal circuits. The aim of this study was to investigate whether dopaminergic dysfunction in Parkinson's disease was associated with impairments in functional connectivity across striatal subdivisions, which could potentially reflect…
  • Dynamic shifts in brain network activation during supracapacity working memory task performance

    Jared X. Van Snellenberg, Mark Slifstein, Christina Read, Jochen Weber, Judy L. Thompson, Tor D. Wager, Daphna Shohamy, Anissa Abi-Dargham, Edward E. Smith
    24 Nov 2014 | 7:25 am
    Abstract Despite significant advances in understanding how brain networks support working memory (WM) and cognitive control, relatively little is known about how these networks respond when cognitive capabilities are overtaxed. We used a fine-grained manipulation of memory load within a single trial to exceed WM capacity during functional magnetic resonance imaging to investigate how these networks respond to support task performance when WM capacity is exceeded. Analyzing correct trials only, we observed a nonmonotonic (inverted-U) response to WM load throughout the classic WM network…
  • Grammatical analysis as a distributed neurobiological function

    Mirjana Bozic, Elisabeth Fonteneau, Li Su, William D Marslen-Wilson
    24 Nov 2014 | 7:23 am
    Abstract Language processing engages large-scale functional networks in both hemispheres. Although it is widely accepted that left perisylvian regions have a key role in supporting complex grammatical computations, patient data suggest that some aspects of grammatical processing could be supported bilaterally. We investigated the distribution and the nature of grammatical computations across language processing networks by comparing two types of combinatorial grammatical sequences—inflectionally complex words and minimal phrases—and contrasting them with grammatically simple words. Novel…
  • Multicontrast connectometry: A new tool to assess cerebellum alterations in early relapsing-remitting multiple sclerosis

  • Improving efficiency and decreasing scanning time of sonographic examination of the shoulder by using a poster illustrating proper shoulder positioning to the patient

    Amit Shah, Maslah Amin, Sriram Srinivasan, Rajesh Botchu
    7 Nov 2014 | 4:00 am
    ABSTRACT PurposePatients often have difficulty performing the various movements required for ideal positioning to enable accurate sonographic (US) assessment of the shoulder; this may result from pain and or unclear oral instructions. We performed this study to ascertain whether the use of a poster depicting the positions required during the examination would decrease scanning time and hence improve the overall efficiency of shoulder US. MethodsWe retrospectively compared results from 50 consecutive patients who underwent US examination without (group 1) and 50 with (group 2) the use of an…
  • A case report of transverse testicular ectopia with testicular microlithiasis

    Qiqi Lam, Gemma Miles, Emma Marsdin, Paul McInerney, Simon Freeman
    7 Nov 2014 | 3:59 am
    ABSTRACT Transverse testicular ectopia is a rare congenital anomaly in which both testes migrate along the same inguinal canal toward the scrotum. This report describes the case of the rarest form of transverse testicular ectopia in a 23-year-old man with coexisting testicular microlithiasis in one of the two testes as diagnosed on sonography and confirmed on MRI. We are unaware of any previous published reports of this association. Although the etiology of both conditions is debatable, each is believed to be associated with an increased risk of testicular malignancy, and this poses a dilemma…

  • Be humble, Be yourself

    Sumer Sethi
    25 Nov 2014 | 12:43 am
    Most fundamental trait which makes a good learner is humility.  And learning is a lifelong process. Day you stop being humble enough to receive, that day your influx of wisdom and knowledge slows down.   Probably, this is the reason in ancient times, Indian gurukuls made even princes beg for alms to learn humility.    If you are too full of yourself, there is no space for new knowledge or wisdom to enter.  Sometimes, I feel we were born humble, we acquire pride on the way, but life in itself manages to give you a lesson in humility. As C.S. Lewis said, “Humility is…
