"WebAfter a stress test, your physician may mention that you have “soft tissue artifact,” or “soft tissue attenuation.” What this means is that soft tissue, such as breast tissue, is showing up on the image created by the stress test. Soft tissue artifact can give the false appearance of an area of reduced blood flow to the heart. " - Diaphragmatic attenuation noted

WebOct 1, 2003 · Myocardial perfusion imaging has traditionally been performed with the patient in the supine position. Supine images, however, are often associated with diaphragmatic attenuation of the inferior wall, thus subject to false-positive inferior wall defects that reduce test specificity ( 1, 2 ). WebIn attenuation-corrected images, apical thinning of any degree was present in 78% of the abnormal patients and 63% of the normal subjects (P = not significant [NS]). However, moderate or severe apical thinning was present in 30% of the abnormal patients compared with 5% of the normal subjects (relative risk = 2.2, P <.001).

WebSince the location of the attenuation artifact depends on the size, shape, and position of the soft tissues near the LV, the CT attenuation map of the surrounding structures can be useful for each patient. Diaphragmatic attenuation of the LV is quite common, resulting in an artifactual perfusion defect in the inferior wall.
