WebResulting myocardial activity maps were analyzed with standardized inferior-anterior and anterior-lateral wall ratios. At a subdiaphragmatic-myocardial activity ratio of 0.5:1, inferior wall attenuation predominates, producing a cold artifact. AC corrects inferior wall activity to the level of the anterior wall irrespective of diaphragmatic motion. WebDec 1, 2004 · In radionuclide cardiac imaging, an inferior wall artifactual defect, so called “diaphragmatic attenuation”, is particularly common and vexing. Despite the historically held view, analysis and review of the literature suggest the defect is likely not diaphragmatic but rather primarily due to attenuation by nearby stomach wall.

WebDiaphragmatic attenuation • Left hemidiaphragm, right ventricle (lesser degree) => decrease count density in inferior wall of left ventricle • Diaphragmatic elevation: obesity, pleural or pulmonary parenchymal disease, atelectasia, loss of lung volume, diaphragmatic paralysis, gastric dilation. Diaphragmatic attenuation WebJul 1, 2005 · With diaphragmatic motion, the cold-attenuating spleen and the hot activity-containing liver and stomach moved into the position previously occupied by the myocardium so that count averaging occurred between these structures and the myocardium.

WebJan 7, 2024 · A fixed perfusion defect with preserved wall motion can be attributed to soft tissue attenuation artifact, such as breast attenuation or inferior wall attenuation caused by the diaphragm, ascites, large pleural effusions, or by other abdominal visceral structures. WebWhat does diaphragmatic attenuation mean? A term utilized in styles of radio photograph imaging, it denotes an exact or obvious loss of blood flow of the guts muscle probably due to the muscular tissues that handle the diaphragm.
