Incomplete transverse myelitis (ITM) of unknown origin is associated with high rates of morbidity and mortality. This prospective, open-label study was undertaken to determine whether antituberculous treatment (ATT) might help patients with ITM whose condition continues to deteriorate despite receiving IV methylprednisolone treatment. The study consisted of 67 patients with steroid-refractory I...
Purpose In this study, we compared the clinical efficacy of JOINS (SKI306X, SK Chemicals) with placebo on cartilage protection using magnetic resonance imaging (MRI). Materials and Methods Sixty-nine patients were randomized to the JOINS group (200 mg, three times daily for 1 year; n=33) or the placebo group (n=36). Changes in cartilage volume and thickness were measured using MRI. Changes in...
OBJECTIVE Central (truncal) adiposity is associated strongly with insulin resistance and diabetes. There are very few reports comparing methods of trunk fat measurement in their ability to predict glycaemia and insulin resistance. We report a comparative analysis of different trunk fat measurements in predicting glycaemia and insulin resistance in middle aged Indian men. MATERIALS AND METHODS...
PURPOSE We aimed to analyze the characteristics and long-term follow-up results of unexpected enhancing lesions on preoperative magnetic resonance imaging (MRI) of breast cancer patients. METHODS From August 2007 through February 2010, second-look ultrasound (SLUS) was recommended for 84 of 312 breast cancer patients having unexpected enhancing lesions on MRI. SLUS was performed for 85 unexpe...
tau.amegroups.com © Translational Andrology and Urology. All rights reserved. In the emerging field of MRI in prostate cancer (PCa) diagnosis, it has become clear that targeted biopsy with MRI guidance has additional value over systematic transrectal ultrasound-guided biopsies (TRUS-Bx) alone. The targeted biopsy approach driven by a positive MRI increases the diagnostic yield of high-grade [Gl...
Purpose To evaluate the reliability of ultrasound hepatorenal index (US-HRI) and magnetic resonance imaging proton density fat fraction (MRI-PDFF) techniques in diagnosis hepatic steatosis, with spectroscopy (MRS-PDFF) as reference standard. Materials methods Fifty-two adult volunteers (30 men, 22 women; age, 31.5 ± 6.5 years) who had no history kidney disease or viral/alcoholic hepatitis were ...
در بررسی و مطالعات مغزی و به منظور شناخت بیمارهای مغزی، از روش های مختلفی مانند تصویر برداری استفاده می شود. شناخت دقیق و به موقع بیماریهای مغزی، به منظور درمان صحیح و افزایش شانس درمان، بسیار مهم می باشد. بیماریهای مغزی را می توان به دو دسته آناتومیک و متابولیک تقسیم نمود. برای مطالعات آناتومیکی می توان از روشهای توموگرافی کامپیوتری با اشعه ایکس و یا رزونانس مغناطیسی هسته ای استفاده نمود. با ت...
Human umbilical tissue-derived cells (hUTC) represent an attractive cell source and a potential technology for neurorestoration and improvement of functional outcomes following stroke. Male Wistar rats were subjected to a transient middle cerebral artery occlusion (tMCAo) and were intravenously administered hUTC (N = 11) or vehicle (N = 10) 48 hrs after stroke. White matter and vascular reorgan...
در این پایان نامه به مدل سازی ریاضی و بررسی عمل تصویربرداری از پدیده تشدید مغناطیسی (mri)در رگ های خونی پرداخته شده است. ابتدا در فصل اول عملکرد دستگاه هایی که توسط آنها mri انجام می شود، بررسی شده اند. در فصل دوم مقدمات مربوط به بررسی ریاضی mri ارائه شده است. در فصل سوم به مدل سازی ریاضی پدیده تشدید مغناطیسی در رگ های خونی پرداخته شده است. ملاحظه می شود که در نهایت مدل ریاضی نتیجه شده به صورت ...
BACKGROUND Recurrence rates following radiotherapy for prostate cancer in the post-operative adjuvant or salvage setting remain substantial. Previous work from our institution demonstrated that published prostate bed CTV guidelines frequently do not cover the pre-operative MRI defined prostate. Inadequate target delineation may contribute to the high recurrence rates, but increasing target volu...
