Fixed defect on nuclear stress test
WebA “soft tissue artifact” may show up on an image produced by a nuclear stress test. During a nuclear stress test you receive an injection of a special radioactive dye that then travels through your blood vessels. A nuclear camera is used to take color-coded pictures of the heart to measure blood flow before, during and after exercise. WebPerfusion imaging revealed a predominantly fixed defect involving the anterior and anterolateral walls of the left ventricle and an ejection fraction of 31%. Subsequently, the patient had a cardiac catheterization …
