  • Abstract
  • Look Inside

1. Videotape recording system was introduced in radioisotope cerebral anglography with 99mTc pertechnetate and in 133Xe cerebral scintigraphy. Time-activity data were fed into a 1-inch wide vi-deotape and displayed later on the oscilloscope for detailed study and eventual photographic recording.

2. The method proved to be of extreme value for (1) improving the detection rate, especially of the small pathologic foci, (2) decreasing the error of instrument setting which is often inevitable with direct photographic recording method, and (3) cutting down the patient's expense for exami-nation.

3. By use of pen-writing recorder, videotape recording method provided the time-activity curves and the regional cerebral blood flow, cerebral vas-cular bed, and cerebral transit time could be cal-culated for multiple regions of interest. In cere-brovascular disorders, those data of regional cir-culation apparently were of great value for clinical as well as research purposes, particularly in combi-nation with the visual images of radiosotope angi-ogram and 133Xe cerebral scintigram.
