Two simple inexpensive photographic methods for viewing ECG-gated radionuclide blood pool images

S Afr Med J. 1979 Apr 28;55(18):725-7.


Although the ECG-gated radionuclide blood pool scan (GBPS) has become an established method for studying regional myocardial wall motion, it is usually performed with the aid of an expensive computer system. A simple, inexpensive method was developed to view gated radionuclide blood images by a film loop and a photographic motion detection (PHOMOT) technique. These techniques were compared with left ventricular cine angiography in 15 patients. Segmental wall movement (78 segments) showed identical results in 92% of cases. In all patients the same diagnosis was arrived at by GBPS and cine angiography. The photographic techniques developed offer a simple screening procedure to reduce cardiac catheterization in patients with suspected abnormalities of left ventricular wall contraction.
