| Question|| |
Please read the patient history and then interpret the images.
- Patient is a 67-year-old male, known hypertensive, diabetic, nonsmoker, with no family history of heart disease
- He presented with complaints of dyspnea on exertion for the last 2 months
- He was referred for stress-rest thallium-201 myocardial perfusion single-photon emission computed tomography [Figure 1].
| Answer|| |
- Stress images demonstrate hypoperfused anteroseptal wall, septum, apex (marked with thick white arrows), and inferior wall (marked with thin white arrows). Rest images demonstrate marked improvement in all the above-mentioned perfusion defects. These findings signify stress-induced ischemia in the anteroseptal wall, septum, apex, and inferior wall [Figure 2].
- In addition, poststress planar images [Figure 3] demonstrate uptake in the lungs (marked with red arrow). Furthermore, there is transient ischemic dilation (left ventricular cavity size appearing larger on stress images compared to rest images), suggestive of subendocardial ischemia. Both these findings may be indicative of multivessel involvement.
