Although the Magnetic resonance imaging with contrast is the gold standard for diagnosis of intra axial brain masses. The conventional Magnetic resonance imaging appearances of intra axial...
The goal of this clinical research study is to learn if using 2 different kinds of contrast agents (Eovist [gadoxetate] and Gadovist [gadobutrol]) given at the same time is better than usi...
The purpose of this study is to assess the impact of TMP001 in the treatment of patients with relapsing-remitting multiple sclerosis (RRMS). Therefore the average total number of contrast ...
RATIONALE: Endoscopic Ultrasound is the leading method to evaluate the pancreas but there may be difficulty characterizing small lesions, non-adenocarcinomas, and possible neoplasia in the...
This study is being conducted as a phase IV, double-blind, multi-center, randomized, crossover trial aimed at a within-subject comparison of MULTIHANCE and GADOVIST at a dose of 0.1 mmol/k...
Iron accumulates with age in the normal human brain. This process is altered at several levels in the brain of multiple sclerosis (MS) patients. Since iron is mainly stored in oligodendrocytes and mye...
Hepatocyte-specific contrast media are gadolinium chelates that are taken up by hepatocytes and partially cleared via the biliary tree. The absence of lesional uptake of the contrast media in the hepa...
Small hepatic masses frequently do not have distinct margins on B-mode EUS image. Contrast-enhanced harmonic EUS (CEH-EUS) is widely used for evaluating ambiguous pancreatic lesions. However, its role...
Neurosarcoidosis is difficult to diagnose, because definite diagnosis requires detailed histology of the central nervous system. Three-dimensional contrast-enhanced fluid-attenuated inversion recovery...
Larmor-frequency shift or image phase measured by gradient-echo sequences has provided a new source of MRI contrast. This contrast is being used to study both the structure and function of the brain. ...
A mixture of isomers used as contrast medium, mainly for brain and spinal cord visualization.
Radiography of the vascular system of the brain after injection of a contrast medium.
Electrical waves in the CEREBRAL CORTEX generated by BRAIN STEM structures in response to auditory click stimuli. These are found to be abnormal in many patients with CEREBELLOPONTINE ANGLE lesions, MULTIPLE SCLEROSIS, or other DEMYELINATING DISEASES.
Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.
Infection of the brain, spinal cord, or perimeningeal structures with the larval forms of the genus TAENIA (primarily T. solium in humans). Lesions formed by the organism are referred to as cysticerci. The infection may be subacute or chronic, and the severity of symptoms depends on the severity of the host immune response and the location and number of lesions. SEIZURES represent the most common clinical manifestation although focal neurologic deficits may occur. (From Joynt, Clinical Neurology, 1998, Ch27, pp46-50)
