CT of Acute Cerebral Ischemia From:
Editor: With great interest, I studied the State of the Art review by Dr Beauchamp and colleagues in the August 1999 issue of Radiology (1), in which they make the important point that the responsibilities of radiologists are increasing with regard to acute stroke management. I am disappointed, though, that the computed tomography (CT) section of this article contains what I consider to be erro...
متن کاملXe/CT cerebral blood flow evaluation of delayed symptomatic cerebral ischemia after subarachnoid hemorrhage.
PURPOSE We examined the xenon/CT method of measuring cerebral blood flow in assessing the location, pattern of onset, and severity of delayed cerebral ischemia. PATIENTS AND METHODS Fourteen patients with delayed neurologic deficits due to ischemia were selected from a group of 66 patients with subarachnoid hemorrhage. All blood flow studies were performed within 12 hours of deterioration and...

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...
15 صفحه اولMultisection dynamic CT perfusion for acute cerebral ischemia: the "toggling-table" technique.
A new CT perfusion technique providing extended anatomic coverage was evaluated in 12 patients with suspected acute middle cerebral artery ischemia. With a multidetector CT scanner, scans were obtained in an alternating fashion at two distinct "toggling" table positions (two 1-cm sections each) during a 40-mL contrast agent bolus (approximately 5 seconds per image), and perfusion parameter maps...
متن کاملAcute cerebral ischemia: CT and MR findings.
It has been reported in two recent papers (1, 2) that magnetic resonance (MR) imaging is more sensitive than computed tomography (CT) in the detection of acute cerebral ischemia. We believe this is not entirely true, at least concerning the early phase of ischemic stroke (within 4 hours from the onset of symptoms). It is our conviction that the earlier the recognition of initial parenchymal inj...
