Abstract
For quantitative analysis of Thallium-201 myocardial imaging, the computer program "CMBF" in Scintipac-1200 (Shimazu) was used in 50 patients with antero-septal myocardial infarction. In "CMBF", the Thallium myocardial image was divided into 8 areas, then Thallium Uptake Index (T.U.I.) was calculated in each area by this Formula;
T.U.I. Counts of the area/Pixels of the area /Total counts of 8 areas/Total pixels of 8 areas
In most patients, T.U.I. was obtained under 0.7, having a close correlation to the diagnosis made by imaging.
