Computed tomography and brain scintigraphy in ischemic stroke. [/sup 99//super m/ Tc]

Journal Article · · Am. J. Roentgenol.; (United States)
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 sign 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.
