X-ray computed tomography (CT) study of small, deep and recent infarcts (SDRIs) of the cerebral hemispheres in adults

摘要: The evolution of CT signs small, deep infarcts the cerebral hemispheres in thirty adults, first five weeks, has been retrospectively studied. relevant literature reviewed and an attempt made to present a synthesis, accompanied by commentary. It is impossible now give frequency each type evolution, but main data are as follows: 1. shortest delay visibility hypodense area about 17 19h, at 27 h densities may still be normal. 2. also variable: after minimum attenuation reached-at approximately 72 h-there risk “fogging effect”, which reduces ischemic lesions; it could seen from end 1st week beginning 4th, its duration have yet better determined. 3. In our series, contrast enhancement found gray matter basal ganglia between 8th 22nd days-but according some observations recorded literature, second twenty sixth day-and there was no obvious white matter. significance evolving discussed connection with clinical applications, principally management these patients, attempts correlate findings.
