Radionuclide cardiovascular radiography

Equilibrium radionuclide cardiovascular radiography (ERNA) includes the following items: ① blood pool imaging, blood pool images of space-occupying lesions in organs such as liver and spleen are thicker than normal tissues and are characteristic of cavernous hemangioma ② The wall motion movie shows that the wall tumor is characterized by no movement of the local wall at rest or an abnormal pulsation. The abnormal pulsation appears or is more obvious after exercise. This method is convenient to observe the changes before and after treatment to judge the efficacy. ③ Cardiac function measurement, the sensitivity to myocardial ischemia is about 85%, which is higher than exercise electrocardiogram (sensitivity is about 65%). Because exercise ECG is simpler, it is still the preferred method for diagnosing myocardial ischemia. However, when the results are not consistent with the clinical situation and the intended diagnosis, or there are factors affecting the analysis of ECG (such as bundle branch block, etc.), this can be used. law. This method is also commonly used to observe the effects of drugs and surgery.
