RT Journal Article SR Electronic T1 Large Abdominal Photopenic Area on 99mTc-Sestamibi Myocardial Perfusion Imaging JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 281 OP 282 DO 10.2967/jnmt.111.102079 VO 40 IS 4 A1 Jennifer Lyon A1 John Spaulding A1 Paul M. Zack YR 2012 UL http://tech.snmjournals.org/content/40/4/281.abstract AB 99mTc-sestamibi myocardial perfusion imaging is frequently performed in conjunction with exercise or pharmacologic stress testing for evaluation of coronary heart disease. Interpretation of these studies includes systematic review of unprocessed rotating projectional images for evaluation of cardiac size as well as the presence of motion or attenuation artifacts. Occasionally, incidental noncardiac findings are detected on review of the projectional images. We report a case of a patient with a history of autosomal dominant polycystic kidney disease who was found to have a large abdominal photopenic area on the projectional images. The photopenic area corresponded to the location of large intraabdominal cysts on abdominal CT and was consistent with hepatic cysts associated with the patient’s known polycystic kidney disease. We review the differential diagnosis of large abdominal photopenic regions identified on myocardial projectional images and the importance of routinely analyzing these images for incidental noncardiac findings.
