A 5-year-old girl with high-risk neuroblastoma underwent ¹²³I-MIBG SPECT/CT after resection of a right adrenal tumor; baseline imaging showed no abnormal uptake.
Persistent Colonic Activity on 99m Tc-MDP Whole Bone Scintigraphy Revealing a Complex Ureterorectal Fistula.
Intense bowel activity on 99m Tc-MDP bone scintigraphy is often dismissed as urinary contamination or radiopharmaceutical instability, but persistent uptake should prompt an anatomic search.
SSTR Antagonist PET/CT Unveils Occult Hepatic Metastases in Rectal Neuroendocrine Tumor: Superiority Over 68 Ga-DOTANOC and Clinical Upstaging.
68 Gallium NODAGA-JR11, a somatostatin receptor (SSTR) antagonist, exhibits superior sensitivity in detecting hepatic metastases of neuroendocrine tumors compared with the agonist tracer 68 Ga-DOTANOC PET/CT.

An incidental gastric gastrointestinal stromal tumor (GIST) was identified and evaluated using three separate PET radiopharmaceuticals.
Metabolic Tumor Volume Is More Accurate Than SUV Metrics in PSMA-PET/CT Analysis Across Different PET/CT Scanners.
A 66-year-old man with metastatic prostate cancer had PSMA-avid local recurrence on follow-up PSMA-PET/CT and MRI. Across three PET studies, SUVmax, SUVmean, and total lesion glycolysis (TLG) did not track consistently…
Focal Vascular Photopenia as a Metabolic Signature of Pulmonary Embolism on AI-Enhanced 18 F-FDG PET/CT.
Artificial intelligence (AI)-enhanced reconstruction of 18 F-FDG PET/CT may reveal important metabolic patterns barely visible on standard reconstructions.
Discordance of 99mTc-PYP Uptake in the Myocardium and Breast Both Before and After Treatment in Transthyretin Cardiac Amyloidosis.
