Comparison of CT and MRI, with and without Contrast Enhancement, in the Detection of Brain TumorsMagnetic resonance imaging (MRI) as a clinical investigation became available in the early 1980s. Since then this method has proven to be a valuable additional diagnostic tool in the recognition and ...
CT scans are often used to find cancer, bone fractures, internal bleeding, blood clots, and injuries to the spine and brain. An MRI shows certain diseases that a CT scan can’t. For instance, uterine, prostate, and certainliver cancersare hard to see on a CT scan. Also, an MRI is u...

h On the non-contrast CT, the tumor presented as sharply margin, ovoid shape with fat density; the CT attenuation value was − 50 HU (white arrowhead). i–j The transverse view of arterial and venous phases of CECT images revealed no enhancement of the tumor Full size image...
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...

Delineation of various target volumes using contrast-enhanced magnetic resonance imaging (MRI) and/or computed tomography (CT) constitutes the primary step for radiation therapy planning (RTP) in brain tumors. This study presents a quantification and comparative evaluation of the various clinical target...

In this study, prototype harmonisation criteria for PET brain studies were developed. Methods Twelve clinical PET/CT systems (4 GE, 4 Philips, 4 Siemens, including SiPM-based "digital" systems) were used to acquire 30-min PET scans of a Hoffman 3D Brain phantom filled with ~ 33 kBq·mL ...
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 ...
