Objective Prediction of the prognosis of comatose survivors after cardiopulmonary arrest (CPA) The lower limit of confidence interval (CI) of the area under the curve (AUC) of the ROC was higher than 0.5 for visual, motor and total scores of GCS and FOUR score. Presence of a lesion pattern of multilobar, or diffuse, cortical involvement, termed as "extensive cortical lesion pattern" in MR imaging was a very good predictor of poor prognosis with an AUC of ROC of 0,937. Sensitivity of GCS motor part score and MR was 87.5% (95% CI: 61.6%-92.6%). Motor part of the

High-resolution sonography can identify and locate the postganglionic injury associated with the upper and middle trunks. The ability of sonography to evaluate pre- and the postganglionic injury associated with the lower trunk was quite limited. Sonography can be used as a complement to MR imaging; thus, the duration of the MR imaging examination and the need for sedation can be reduced by sonography.

M alignant gastroduodenal obstruction (GDO) is a common and debilitating complication of advanced gastric, duodenal, and pancreatobiliary cancers. It can also be seen due to lymphoma and metastatic spread of other malignancies (1, 2). Patients classically present with abdominal pain, nausea, and vomiting with resulting malnutrition and weight loss (1-3). The majority of patients have a median survival of only 3-6 months (4, 5).Curative surgery is often not possible and palliative surgical procedures might have high complication rates with delayed postoperative gastric emptying and prolonged hospitalization (1,(5)(6)(7)(8).Fluoroscopic or endoscopic placement of covered and uncovered metallic stents has been commonly performed in the palliation of malignant GDO as an alternative to gastrojejunostomy (GJ) with high technical and clinical success and low complication rates (5). However, recurrent obstruction due to tumor ingrowth and stent migration is a drawback of uncovered and covered metallic stents.The purpose of this study is to evaluate safety and effectiveness of fluoroscopy-guided gastroduodenal metallic stent placement using different approaches such as transoral, transgastric, and transhepatic in 53 patients with malignant obstruction. Patients who underwent combined biliary and duodenal stenting were also assessed. I N T E R V E N T I O N A L R A D I O LO G Y O R I G I N A L A R T I C L E PURPOSEWe aimed to evaluate the safety and effectiveness of fluoroscopy-guided gastroduodenal metallic stent placement with different approaches in malignant obstruction. METHODSWe retrospectively assessed 53 patients (33 men and 20 women; mean age, 58.7±15 years) who underwent stent placement between February 2004 and April 2014. All patients had unresectable tumors. The most common causes of obstruction were gastric (38%) and pancreatic cancers (36%). Uncovered self-expandable metallic stents (SEMS) were placed under fluoroscopic guidance. In addition to transoral approach in 46 patients (86.7%), transgastric and transhepatic approaches were used in six patients (11.3%) and one patient (1.8%), respectively. Gastric outlet obstruction scoring system (GOOSS) was used to evaluate oral intake before and after stenting. Patients were followed until death or the end of the study. RESULTSTechnical and clinical success rates were 100% and 92%, respectively. The median stent patency was 76 days (range, 4-985 days). Mean preprocedural GOOSS score of 0.1 increased to postprocedural GOOSS score of 2.42 (P < 0.001). Afferent loop decompression was achieved in one symptomatic patient. Neither mortality nor major complications occurred due to stenting. Stent migration occurred in one patient (2%) and stent obstruction occurred in two patients (4%). Combined biliary and duodenal stenting were performed in 21 patients (40%). Post-stenting GOOSS scores were predictive of survival (P = 0.003). CONCLUSIONFluoroscopic metallic stent placement for palliation of malignant gastroduodenal obstruction is safe and effective with high technica...

It is important for radiologist to know that os intermetatarseum can be presented as dorsal foot pain. Due to its position, it is difficult to demonstrate os intermetatarseum in plain radiographs, CT and MRI should be performed in clinically suggestive cases.

MRI is an essential component in evaluation of spinal involvement in MPS VI, and scanning of the entire spine is recommended to rule out thoracic cord compression. Advances in knowledge: This study provides a detailed description of spinal MRI findings in MPS VI and underlines the role of MRI in management of cord compression.

Image quality in non-contrast-enhanced (NCE) angiograms is often limited by scan time constraints. An effective solution is to undersample angiographic acquisitions and to recover vessel images with penalized reconstructions. However, conventional methods leverage penalty terms with uniform spatial weighting, which typically yield insufficient suppression of aliasing interference and suboptimal blood/background contrast. Here we propose a two-stage strategy where a tractographic segmentation is employed to auto-extract vasculature maps from undersampled data. These maps are then used to incur spatially adaptive sparsity penalties on vascular and background regions. In vivo steady-state free precession angiograms were acquired in the hand, lower leg and foot. Compared with regular non-adaptive compressed sensing (CS) reconstructions (CSlow ), the proposed strategy improves blood/background contrast by 71.3 ± 28.9% in the hand (mean ± s.d. across acceleration factors 1-8), 30.6 ± 11.3% in the lower leg and 28.1 ± 7.0% in the foot (signed-rank test, P < 0.05 at each acceleration). The proposed targeted reconstruction can relax trade-offs between image contrast, resolution and scan efficiency without compromising vessel depiction.
