A simple practical technique to alleviate the problem of interfering subdiaphragmatic intestinal activity on myocardial perfusion imaging

Images that Teach


Myocardial perfusion imaging as a validated diagnostic tool for cardiac evaluation, can be influenced by many factors including technical ones. Handling of these technical factors may be challenging for technologists to prevent imaging artifacts.

Case History

A 56-year-old male was referred to our department for preoperative cardiac evaluation. A dipyridamole myocardial perfusion SPECT was performed with same-day stress-rest protocol. Stress images were unremarkable but on rest images (Figure  1), a high amount of subdiaphragmatic activity was detected adjacent to inferior wall of left ventricle. Delayed imaging was not helpful (Figure  2). The scan was repeated immediately after drinking of three glasses of plain water (Figure  3).
