Correlation of EBCT and TL-201-SPECT Scintigraphy in Patients with Coronary Heart Disease

The aim of the study was to compare the findings of EBCT with those of Tl-201-scintigraphy. 12 patients with CAD were investigated. The 14 fixed Tl-defects were associated with coronary artery stenosis of more than 50% in 5 cases, with atherosclerotic plaques in 2 cases. The 7 non-persisting defects were associated with coronary artery stenosis of more than 50% in 3 cases, with irregularities of the arterial wall in 3 cases, and with atherosclerotic plaques in 2 cases. Contractility and athrophy as seen on EBCT did not correlate with typical findings on scintigraphy. The preliminary data show that EBCT and Tl-scintigraphy do not replace but complement each other.
