By means of coronarography in the most favourable case only the morphology and function of the vessels up to a diameter of 0.1 mm may be established. By the selective coronary perfusion scintigraphy this gap is closed, for it allows a judgment also of the terminal vascular system of the myocardium. The basis of this method is an occlusion of the arterioles and capillaries by radioactively labelled microspheres, in which case, however, only every 10,000th to 20,000th vessel is embolized for a short time. Thus the proper selective perfusion scintigraphy is for the patient a procedure which is not stressing, which, however, demands a sounding of the coronary vessels. On the basis of our own previous results this investigation method is indicated in the diagnostics of the ischaemic heart disease also in its atypical form, in the indication to the vascularisation operation with aortocoronary bypass and its postoperative control as well as in the cardiomyopathies. Also in load examinations and in pharmacological tests by their use as double nuclide method an enlarged information can be got. The importance of the perfusion scintigraphy is among others shown in patients with normal coronarogramme, but with perfusion disturbances which can be proved by means of this method. The most comprehensive invasive diagnostics in the diseases mentioned is at present achieved by the combination of coronarography, ventriculography and selective perfusion scintigraphy.
