[Quantitative evaluation of left ventriculography with contrast media and radioisotopes]

A radioisotopic technique which, through the injection of 99mTc-red cell into the pulmonary artery, gives images of left ventricular chamber in RAO at first pass and in LAO at blood pool gated, has been assessed. A quantitative analysis of left ventricular wall motion was performed with semiautomatic program. The Authors report their experience with 30 CHD patients.
