Diaphragmatic attenuation noted
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. 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 ).
