A <jats:sup>99m<\/jats:sup>Tc-pertechnetate scan with SPECT\/CT was performed to exclude a Meckel's diverticulum. The images demonstrated focal tracer uptake in the right midabdomen, which appeared early and decreased over time. However, SPECT\/CT revealed that this uptake corresponded to the right renal pelvis, which was located more inferior than expected. This case emphasizes the importance of recognizing anatomic variants that may cause focal tracer uptake, as well as leveraging an understanding of tracer kinetics to inform a diagnosis.<\/jats:p>","DOI":"10.1097\/rlu.0000000000004331","type":"journal-article","created":{"date-parts":[[2022,7,22]],"date-time":"2022-07-22T21:00:16Z","timestamp":1658523616000},"page":"173-175","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Excreted 99mTc-Pertechnetate in a Renal Pelvis as a Potential False Positive in a Meckel\u2019s Scan"],"prefix":"10.1097","volume":"48","author":[{"given":"Shannon M.","family":"Lanzo","sequence":"first","affiliation":[{"name":"Department of Radiology, Hospital of the University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Austin R.","family":"Pantel","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hospital of the University of Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongming","family":"Zhuang","sequence":"additional","affiliation":[{"name":"The Children\u2019s Hospital of Philadelphia, Perelman School of Medicine University of Pennsylvania, Philadelphia, PA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","published-online":{"date-parts":[[2022,7,19]]},"reference":[{"key":"bib1-20250621","doi-asserted-by":"crossref","first-page":"784","DOI":"10.1097\/RLU.0b013e318187eef4","article-title":"Focal activity in early phase scan should not be ignored: gastrointestinal stromal tumor detected on Tc-99m pertechnetate imaging","volume":"33","year":"2008","journal-title":"Clin Nucl Med"},{"key":"bib2-20250621","first-page":"886","article-title":"Uterine activity: a potential cause of false-positive Meckel\u2019s scans","volume":"22","year":"1981","journal-title":"J Nucl Med"},{"key":"bib3-20250621","first-page":"440","article-title":"Ileal leiomyosarcoma and leiomyoma.
