سندرم متابولیک مجموعه ای از اختلالات متابولیکی شامل چاقی، هیپرتری گلیسریدمی، عدم تحمل گلوگز، فشار خون بالا و اختلالات لیپیدها است که این مجموعه احتمال ابتلا به بیماریهای قلبی و دیابت نوع 2 را چند برابر میکند. با توجه به افزایش شیوع این اختلال، انجام پژوهش هایی در جهت پیشگیری از ابتلا به این اختلال ضروری می باشد. اخیرا سیستم های مراقبت بهداشت مبتنی بر هوشمصنوعی به دلیل موفقیتهایی که در زمین...
Renal artery stenosis (RAS) is the most common cause of secondary hypertension. Preliminary data indicate that aspirin renography with hippurate may be more sensitive for detection RAS. In this study 20 patients with known or suspected RAS underwent aspirin renography (20 mg/kg orally 1 hour before injection of radiotracer) and captopril renography (50 mg orally) with 99mTc-DTPA. Renal an...
