BACKGROUND AND PURPOSE SWI is an MR imaging technique that is very sensitive to hemorrhage. Our goal was to compare SWI and CT to determine if SWI can show traumatic SAH in different parts of the subarachnoid space. MATERIALS AND METHODS Twenty acute TBI patients identified by CT with SAH underwent MR imaging scans. Two neuroradiologists analyzed the CT and SWI data to decide whether there we...
A 3-year-old boy presented to the emergency department with fever, generalized tonic-clonic seizures, and altered sensorium within 6 hours of administration of the diphtheria, pertussis, and tetanus (DPT) vaccine. The child had features suggestive of raised intracranial pressure with papilledema on fundoscopic examination. Contrast-enhanced computed tomography (CT) of the head (Figure 1) reveal...
OBJECTIVE The objective of this study is to verify the relationship between subarachnoid hemorrhage (SAH) volume (not Fisher grade) and development of cerebral vasospasm prospectively. METHODS Patients who visited our hospital with a diffuse or localized thick subarachnoid blood clot seen on computed tomography (CT), taken within 48 hours after SAH and the aneurysm was confirmed by CT Angiogr...
BACKGROUND AND PURPOSE Experiments were carried out in rabbits to determine whether clentiazem (8-chlorodiltiazem), a cerebrovascular-selective calcium channel blocker, administered 24 hours before subarachnoid hemorrhage influenced the subsequent cerebral vasospasm. METHODS Subarachnoid hemorrhage was induced by multiple injections of blood into the prepontine cisterns of 35 male New Zealand...
The early computed tomographic (CT) findings of acute global central nervous system hypoperfusion were studied in 10 patients. The findings could be characterized as: (1) diffuse mass effect with effacement of the cerebral sulci and of the brainstem cisterns (nine patients); (2) global decrease in the cortical gray-matter density from edema, causing loss of the normal gray-white matter differen...
The diabetic effects of streptozotocin (STZ) were investigated in spleen. In the study, 38 male adultWistar Albino rats with weights 200 ± 20 g were used by separating them into four groups: Control,Vitamin C, Diabetes, Diabetes + Vitamin C. Vitamin C is an important antioxidant. Streptozotocinin sterile physiological saline was injected into animals intravenously. Body weights ...
