The commonly used contrast medium metrizoate (Isopaque Cerebral(R)) or the new nonionic iohexol was injected intravenously for enhancement of cranial CT in a randomized double blind study. Each group consisted of 105 patients. No serious reactions occurred. Ten patients receiving metrizoate had ...
A comparison has been made of contrast medium reactions in contrast-enhanced CT of the cerebrum using Urografin-meglumin and a new non-ionic, low-osmolality radiologic contrast medium, Ultravist. The number of contrast medium reactions was significantly less with Ultravist, but many mild reactions ...
Our clinical population numbered 8516 patients with primary and metastatic brain tumors who underwent evaluation by computed tomography at the neurosurgical and neuroradiologic departments of the Berlin, Mainz, and Munich centers from 1975 to 1986 and at the Neurosurgical Department of Augsburg Central Ho...
We conclude that: (1) delayed high dose scans offer no significant advantage in patients with symptoms suggesting vascular malformation of the brain; and (2) while less specific than immediate contrast CT, these scans do not preclude detection of vascular malformations of the brain. Therefore, ...
with ICH in the non-contrast brain CT scan (NCCT) at presentation, age above eighteen years, and available brain CTA obtained within 48 h from primary NCCT. The exclusion criteria were history of head trauma within the previous two weeks, evidence of ischemic stroke on the site of hemorrhage...
1、CT AND MRI IMAGING OF NORMAL BRAINNORMAL ANATOMY OF BRAINBrain is separated from calvarium by three meninges-dura mater,arachnoid membrane and pia mater. Divided into supra tentorial and infra tentorial compartments containing:- Supratentorium: Cerebral hemispheres diencephalonInfratentorium: Brain...
Fifty-five patients with brain lesions were examined by computed tomography (CT) after two doses of contrast medium: a bolus injection of 65% meglumine diatrizoate, 1 ml/kg, and a bolus injection of 65% meglumine diatrizoate, 1.5 ml/kg, in combination with an infusion of 250 ml meglu...
(CT) is widely used to identify anomalies in brain tissues because their localization is important for diagnosis and therapy planning. Due to the insufficient soft tissue contrast of CT, the division of the brain into anatomical meaningful regions is challenging and is commonly done with magnetic ...
Objective To explore applied value on CT and Brain Atlas (BA) in diagnosis of acute cerebrovascular diseases and compare the contrast between them. Methods Brain Atlas (BA) and CT were exmined in 718 patients with a-cute cerebrovascular disease and contrasted with each othes. Results BA and ...
