Evaluation of Brain Functional Image on Dynamic X-CT. Functional image of Dynamic CTs were evaluated for a comparison with ^<123>I IMP SPECT in 21 patients in the acute cerebral icshemia stage. The lesion detected by FID-CT was very consistent with that shown by SPECT in 81.0% of the patients. So it was shown that this study was useful because the method can be easily and quickly performed and it discloses the ischemic area with a fair degree of certainty. Although, Computed Tomography (CT) instruments of the third generation are expected, they can not completely to seize the fast cerebral blood flow in the arterial phase, so we have studied the quality and patterns of the time density curves regarding 74 cases and compared them with the functional image. No reliance can be placed on the A and TA-images of the functional image, because an error occurs regarding the time of appearance.
