MUGA scan not useful in:-: (A) Left ventricular ejection fractio, (B) Regional wall motion, (C) Regional wall perfusion, (D) Stroke volume
Answer is C. MUGA - Multi-Gated Acquisition scan In this scan, Tc99-m labeled RBC area injected into the patient and gamma camera is focused on hea, then the emitted radio-active substances are assessed using the gamma camera. Useful for measuring Ventricular function of the hea, Ventricular ejection fraction, Stroke volume Ventricular wall motion.
