Computerized axial tomography of intracerebral hematoma. A clinical and neuropathological study.

Excellent correlation between computerized axial tomographic (CT) scans and the location and extent of pathologically verified intracerebral hematomas was demonstrated in eight patients. Superficial and intraventricular extension, hydrocephalus, and mass effect were easily identified; CT scanning was superior to angiography and radionuclide brain scanning in diagnosing hematoma and in determining its extent and associated ventricular size. Angiography was superior to CT scanning in demonstrating aneurysms and arteriovenous malformations as a cause of intracerebral hematoma. Computerized axial tomographic scanning is also useful in following the resolution of hematomas and in guiding surgical intervention.

Individualized computer tomography of the skull with the EMI scanner using the 160 X 160 matrix.

The individualized approach to the performance of computerized tomography of the skull is described. With the use of the 160X160 matrix it is possible to look at the initial scans almost immediately after their completion. If necessary, unsatisfactory scans can be repeated, the position of the head can be changed and artifacts due to motion can be minimized or eliminated. Lesions can be revealed or enhanced with intravenously injected contrast material if desired. The individualized approach has eliminated the need to recall patients and has improved the diagnostic capability of the method.

Computed tomography and radionuclide studies in the diagnosis of intracranial disease.

The accuracy of CT and radionuclide studiies in the diagnosis of intracranial disease is analyzed based on experience in 641 patients. Results indicate that both modalities give reasonably similar precision and that a modest improvement in diagnosis can be expected if both techniques are employed. It is emphasized that the radionuclide studies used routinely included what are rightfully considered adjunctive scanning procedures, so that results must be considered in this light.

Computed tomography and brain scintigraphy in ischemic stroke.

Radionuclide and computed tomographic (CT) scans were reviewed in 215 patients with ischemic stroke. The findings vary depending on the site of vascular occlusion. In middle cerebral artery occlusion, four distinct patterns may be seen on the scintigrams. The CT scans show little variation in appearance. The tentorial confluence sign is an important finding on scintigrams of patients with occipital infarction; the absence of this signs should suggest another diagnosis. During the first week and after the fourth week following an ischemic stroke, the scintigram is usually negative, whereas the lesion is visible by CT. However, there are a significant number of false negative CT scans; therefore, both examinations are advocated in difficult cases.
