Computed Tomography (CT) was used in evaluating five patients with abdominal aneurysms. In one case, an acute aneurysmal leak was evaluated by CT alone prior to surgery. In four cases, significant incidental diagnoses were made via CT The use of CT in evaluating aortic aneurysmal disease is discussed.
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.
