The truncation artifact in a skinny patient following myocardial perfusion SPECT

Myocardial perfusion SPECT is one of the most common imaging techniques performed in nuclear medicine departments. To avoid misleading interpretation, it is necessary to address the quality control and technical problems. The truncation artifact occurs when the patient size is large relative to the field of view of the camera, causing false perfusion defects in the LV myocardium, misinterpreted as myocardial perfusion abnormality. It usually happens in obese patients, who may deviate from the detector field. Here, we present a skinny patient showing myocardial truncation artifact, proved to be because of technical issues.
