case_images: A) Myocardial perfusion at rest (R) and stress (S) with
  technetium-99m-Sestamibi (MIBI) to the right and rubidium-82 (82Rb) to
  the left. Ischemia can be observed in most prominent inferolateral wall
  in 82Rb. B) Left ventricular motility study (GATED-PET) shows apical
  akinesia and severe hypomotility of the left ventricular inferior and
  septal walls, with a decrease in ejection fraction under stress and the
  presence of transient ischemic dilation (volumetric ratio between stress
  and rest of 1.28).

case_images: Initially, the resting image was carried out; approximately 2 hours later, the stress imaging was performed (Figures 1 and 2) using dipyridamole as a stress agent.
case_images: (A) Myocardial blood flow measurements (mL/ min/g) at rest and under
  stress, and coronary reserve in the territories of the left anterior
  descending (LAD), circumflex (LCX) and right coronary (RCA) arteries
  obtained with rubidium/positron-emission tomography. Observe the overall
  reduction in myocardial blood flow and left ventricular (LV) reserve and
  the territories of the three arteries (reserve <2.0). (B) Coronary
  angiography showing 100% occlusion in the anterior descending,
  circumflex and right coronary arteries, as well as the presence of grade
  3 collateral circulation of multiple origin to the anterior descending
  artery, grade 2 in the right coronary artery and grade 3 in the second
  left marginal artery.

case_images: Female patient, 63 years old, reported chest burning pain and dyspnea on exertion for 2 years and was submitted to CAT, which detected CAD (Figure 2). Initially, the resting image was carried out; approximately 2 hours later, the stress imaging was performed (Figures 1 and 2) using dipyridamole as a stress agent.
