Ischemic Colitis Associated with Rhabdomyolysis and Heat Stroke after an Intense Exercise in Young Adult.

Ischemic colitis primarily affects the elderly with underlying disease, but it rarely occurs in young adults with risk factors, such as coagulopathy or vascular disorder. Moreover, it is extremely rare in the very young without risk factors. This paper presents a patient with ischemic colitis associated with heat stroke and rhabdomyolysis after intense exercise under high-temperature conditions.

Use of Imaging to Predict Complete Response of Colorectal Liver Metastases after Chemotherapy: MR Imaging versus CT Imaging.

Purpose To compare the diagnostic performances of contrast agent-enhanced computed tomography (CT) and gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced liver magnetic resonance (MR) imaging (referred to as EOB MR imaging) in the evaluation of disappearing colorectal liver metastases (CRLMs) after chemotherapy. Materials and Methods The eight institutional review boards approved this retrospective study and waived the requirement for informed consent. On the basis of retrospective searches in eight hospitals, 87 patients with 393 CRLMs, each patient with one or more CRLM that later disappeared on contrast-enhanced CT scans after chemotherapy, and subsequently underwent surgery for the CRLMs, were enrolled.

Neuroendocrine neoplasms of the extrahepatic bile duct: radiologic and clinical characteristics.

Purpose: To retrospectively identify the radiological and clinical features of neuroendocrine neoplasms of the extrahepatic bile duct.

Materials And Methods: Institutional review board approval was obtained. Between August 2003 and August 2013, 11 patients (range 41-79 years) who had undergone surgery in our institution for neuroendocrine neoplasms of the extrahepatic bile duct were identified.

CT colonography in the diagnosis and management of colorectal cancer: emphasis on pre- and post-surgical evaluation.

This article addresses the use of computed tomographic colonography (CTC) for the diagnosis and management of colorectal cancer, focusing on presurgical evaluation of the colon proximal to an occlusive cancer and surveillance after cancer resection surgery. The key evidences accumulated in the literature and future work needed are summarized. CTC is a technically robust and the most practical method to evaluate the colon proximal to an occlusive cancer, which prevents colonoscopic examination past the occlusion, either before or after metallic stent placement.

Quality of reporting noninferiority/similarity in research studies of diagnostic imaging.

Purpose: To evaluate the quality of reporting noninferiority/similarity in research studies of diagnostic imaging.

Materials And Methods: All 661 original research articles published in Radiology and European Radiology in 2012 were hand searched to find original studies of diagnostic imaging that included a claim of noninferiority/similarity as a study conclusion. A separate MEDLINE search was performed to identify original studies of diagnostic imaging designed as noninferiority studies, defined as studies at least embodying noninferiority margin, published in English between April 2007 and December 2012.

Primary solid pancreatic tumors: recent imaging findings updates with pathology correlation.

The imaging findings of primary solid pancreatic tumors have long been studied and are generally well-established. However, interestingly enough, a wealth of new information has recently appeared in the literature, including the imaging findings of novel or previously seldom-addressed pathological entities as well as atypical imaging findings of common tumors, both of which are well-correlated with the pathology findings. 5 %-14 % of pancreatic ductal adenocarcinomas have been reported on dynamic contrast-enhanced computed tomography to be isoattenuating, and thus making the imaging diagnosis challenging.
