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 ...
WBCT imaging was defined as CT imaging (with or without contrast) of at least the head, C-spine, chest, abdomen, and pelvis. From:Academic Radiology,2016 Add to Mendeley Also in subject areas: Biochemistry, Genetics and Molecular Biology ...
Statistical analysis was performed of the carefully coded results of computed tomographic scans, with and without contrast medium, of a substantial group of patients with proved diagnoses. Bayesian methods were used to provide computer-aided diagnoses with considerable success. Further analysis of these ...
Non contrast CT scan (a) shows hyperdense lesion with small foci of calcification in the left caudate nucleus and intraventricular hemorrhage (IVH) in posterior horns of lateral ventricles. Coronal (b) and axial (c) cuts of brain CTA shows left caudate nucleus arteriovenous malformation (AVM) w...
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 ...
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...
Whole-brain DWI-MRI was performed for reference standard final core infarct assessment, using either a 1.5 T GE Signa or 3.0 T GE MR750 MRI scanner with an eight-channel GE HR brain coil (GE Healthcare, Milwaukee, Wisconsin). Axial DWI imaging parameters included: TR 6000 ms, TE 78.2 ...
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...
To examine the added diagnostic value of emergent contrast enhanced CT head (CECTH) in patients who present to the emergency department (ED) with acute non-traumatic symptoms referable to the brain, and to assess the financial implications of CECTH in the emergent setting.We queried healthcare ...
Intranasal gliomas usually present at birth or the very young as a soft tissue mass centered at the nasal dorsum. Nasoethmoidal encephaloceles present at birth with a frontal, nasal or medial orbital soft tissue mass contiguous with intracranial ...
