RT Journal Article SR Electronic T1 Ancillary Finding on Myocardial Perfusion Imaging Due to Urinary Bladder Displacement JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 182 OP 183 DO 10.2967/jnmt.121.263344 VO 50 IS 2 A1 Sarah Frye A1 Ejda Bajric A1 Avril Slavin YR 2022 UL http://tech.snmjournals.org/content/50/2/182.abstract AB When patients are referred for SPECT myocardial perfusion imaging with 99mTc agents, attention focuses on the tracer activity in the myocardium. Apart from myocardial activity, normal biodistribution of 99mTc-sestamibi and 99mTc-tetrofosmin is seen in the thyroid, liver, gastrointestinal tract, kidneys, and urinary bladder. These structures may be visualized when a γ-camera with a large field of view is used for SPECT imaging. This case report presents a serendipitous finding of a pelvic mass, which was identified because of the extended field of view afforded by the conventional γ-camera used for SPECT myocardial perfusion imaging and detected because of a review of the raw images by the nuclear medicine technologist. This case emphasizes the importance of training the nuclear medicine technologist to review the raw data in the entire field of view before study completion.
