Answer

As previously noted, gated images are obtained after the stress test is performed. With the use of a single-headed camera, a 180° acquisition is usually obtained with 32 stops. ECG gating is used, even when the patient has a cardiac arrhythmia, such as atrial fibrillation. After image acquisition, processing generates cine images that show wall motion and wall thickening. In addition, ventricular volumes and polar maps are generated. [27, 28, 29, 30, 36, 45, 10, 17]
