[Radionuclide ventriculography as a special case of functional scintigraphy (author's transl)]

Computer processed dynamic scintigraphy (CPDS) (Funktionsszintigraphie), as developed 15 years ago essentially in the German Cancer Research Center (Institute of Nuclear Medicine), Heidelberg, shows limitations with regard to temporal spatial resolution. Under fixed count rate conditions, temporal resolution can only be improved at the expense of spatial resolution. The adverse implications of this inverse relationship may be overcome by the use of trigger techniques, resulting in an improvement in statistical information. The strict application of principles as developed in CPDS in gated blood pool procedures leads to parametric scans (functional imaging) displaying optimal utilisation of available information and presentation of regional wall motion abnormalities.
