Radionuclide ventriculography o labelling of autologous erythrocytes with technetium 99m o ecg gating is used to acquire 16 to 32 frames through the cardiac cycle o imaging of first pass of tracer through heart and or after blood pool equilibrium o first pass good for rv function and l r shunting. Radionuclide imaging exposes patients to less radiation than do comparable x ray studies spect planar techniques which produce a 2 dimensional image are rarely used spect which uses a rotating camera system and tomographic reconstruction to produce a 3 dimensional image is more common in the us radionuclide ventriculography has . Radionuclide imaging exposes patients to less radiation than do comparable x ray studies however because the radioactive material is retained in the patient briefly sophisticated radiation alarms eg in airports may be triggered by the patient for several days after such testing this technique is rarely used now because other . Abstract radionuclide imaging techniques add an important dimension to the diagnosis classification and management of myocardial disease the gated blood pool scan provides information allowing determination of the functional type of cardiomyopathy congestive restrictive or hypertrophic as well as evaluation of ventricular performance
