Purpose: To retrospectively compare accuracy of diffusion-weighted (DW) single-shot echo-planar imaging with sensitivity encoding (SENSE) that superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance (MR) in the evaluation hepatic metastases due to extrahepatic malignancies. Materials and Methods: Patients provided informed consent; ethics committee approval was not required. The data 24 patients (16 men, eight women; age range, 41–68 years; mean age, 61.9 years) 40 resected were...
Objective: The purpose of this study was to assess whether T2-weighted (T2W) imaging with diffusion-weighted (DW) could improve prostate cancer detection as compared T2W alone. Methods: subjects consisted 37 patients and 23 without undergoing magnetic resonance (MR) imaging. Using a 1.5-T superconducting magnet, all underwent DW parallel Images were independently reviewed by 3 readers determine the detectability cancer. assessed means receiver operating characteristic analysis. Results: Mean...
To determine the clinical importance of bird-beak configuration after thoracic endovascular aortic repair (TEVAR).The institutional review board approved this retrospective study and waived requirement to obtain informed consent from patients. Sixty-four patients (40 men, 24 women; mean age, 64 years) who underwent TEVAR were evaluated. The treated diseases included dissection (n = 29), degenerative aneurysm 13), acute traumatic transection 8), pseudoaneurysm 4), penetrating ulcer 6),...
This article describes the combustion behavior of combustible gases as they are released from clathrate cages a hydrate. Gas hydrates (clathrates) ice-like crystalline solids that encapsulate guest gas molecules. It has become known significant methane storehouse is in form on sea floor and arctic permafrost. There great interest this large fuel storehouse, particularly how to extract clathrates. One unique features it flammable, despite being 85% water – fiery ice. While clathrates most...
Purpose: To prospectively evaluate delayed gadolinium-enhanced magnetic resonance (MR) imaging of cartilage for assessment glycosaminoglycan (GAG) concentration in reparative after autologous chondrocyte implantation (ACI). Materials and Methods: The study was approved by the ethics review committee National Institute Radiological Sciences, informed consent obtained from all patients. group comprised nine knees patients (six male, three female; mean age at ACI, 21.2 years ± 7.5 [standard...
ABSTRACT Systemic primary carnitine deficiency (SPCD) is a rare congenital fatty acid metabolism disorder causing impaired β‐oxidation and energy production, leading to hypoglycemia, metabolic encephalopathy, sudden death. Early diagnosis treatment, including L‐carnitine supplementation fasting avoidance, can improve prognosis. However, newborn screening (NBS) criteria differ by region, standardized guidelines are lacking. This report presents case of SPCD undetected NBS, resulting in basal...
The motions of chest wall and diaphragm were measured in patients with scoliosis healthy individuals using dynamic breathing magnetic resonance imaging.To investigate the during deep idiopathic scoliosis.Despite central role respiratory maintaining ventilation, it is difficult to measure describe because limited methods available. kinematics respiration have not yet been clarified.Dynamic fast spoiled gradient-recalled echo sequences used for 18 9 individuals. evaluated a cineloop view...
The purpose of our study was to describe the various magnetic resonance (MR) findings pleomorphic adenoma and interpret these findings.MR studies 33 adenomas 13 malignant tumors in major salivary glands were reviewed.High signal intensity on short-inversion-time inversion recovery (STIR) T2-weighted (T2W) images, progressive enhancement dynamic MR high apparent diffusion coefficient (ADC) values diffusion-weighted (DW) images reflected myxoid-dominant components adenomas. Hypercellularity...
Since survival after postoperative non-small-cell lung cancer (NSCLC) recurrence is extremely poor, the long-term post-recurrence outcomes are not well understood. The purpose of this study was to evaluate and clarify who possibly ‘cured’ in recent clinical practice. We reviewed medical records 635 patients developed until 2012 R0 resection for pathological Stage IA–IIIA NSCLC between 1993 2006. Factors associated with (PRS) characteristics (≥5 years) survivors were analysed retrospectively....
To illustrate the CT findings of gastrointestinal anisakiasis.The Institutional Review Board approving this retrospective study waived requirement for informed consent. our emergency department's clinical records from September 2008 to January 2012 identified 41 consecutive patients who were diagnosed with anisakiasis. 20 gastric anisakiasis endoscopically proven Anisakis larvae, and 21 intestinal positive test results anti-anisakidae antibody presence lesions on CT. Two radiologists...
Antegrade perfusion for type A acute aortic dissection prevents malperfusion and retrograde cerebral embolism during cardiopulmonary bypass. Prompt establishment of antegrade via ascending aorta may improve the surgical results dissections, especially in situations hemodynamic instability. Thus, we evaluated efficacy use dissected as an alternative arterial inflow.Between 2002 2006, 32 patients underwent prosthetic graft replacement or hemiarch dissection. The was routinely cannulated,...
Symptoms of an adverse reaction to contrast agents for computed tomography are diverse ranging, and sometimes serious. The goal this study is create a scoring rule predict reactions used in tomography.This was retrospective cohort all adult patients undergoing enhanced CT scan 7 years. subjects were randomly divided into either derivation or validation group. Baseline data clinically relevant factors collected from the electronic chart. Primary outcome any acute media, observed during 24...
Abstract Aims Current approaches to classify chronic heart failure (HF) subpopulations may be limited due the diversity of pathophysiology and co‐morbidities in HF. We aimed elucidate clusters patients with HF by data‐driven machine learning a hospital‐based registry. Methods results A total 4649 broad spectrum left ventricular ejection fraction (LVEF) CHART‐2 (Chronic Heart Failure Analysis Registry Tohoku District‐2) study were enrolled this study. Chronic classified using random forest...
To study the relationship between follicular atresia, apoptosis, and nitric oxide (NO) generation in development, steroidogenesis, NO levels fluid apoptosis were analysed various sized follicles of women receiving ovarian stimulation with human meno-pausal gonadotrophin (HMG)—human chorionic gonado-trophin (HCG) treatments for in-vitro fertilization (IVF)-embryo transfer. The divided into three groups by diameter: large follicle, ≥18 mm; medium ≥12 ≤15 small ≤10 mm. Follicular was obtained...
