Inguinal/pelvic lymph node involvement in penile squamous cell carcinoma by 18 F-fluorodeoxyglucose PET/CT.
This systematic review and meta-analysis assessed 18F-FDG PET/CT accuracy for detecting inguinal and pelvic lymph node metastases in penile squamous cell carcinoma.
False-Positive 123I-MIBG Uptake Attributable to Contralateral Erector Spinae Muscle Hypertrophy Following Retroperitoneal Surgery in a Child With Neuroblastoma.
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.
Comparison of lesion detection rates between FAPI PET/CT and 18 F-FDG PET/CT in hepatocellular carcinoma: a systematic review and meta-analysis of head-to-head studies.
This systematic review and meta-analysis compared lesion detection by fibroblast activation protein inhibitor (FAPI) PET/CT and 18F-FDG PET/CT in hepatocellular carcinoma (HCC), using head-to-head studies.
68 Ga-granzyme B ( 68 Ga-NOTA-GSI) PET/CT for predicting immunotherapy response and progression free survival in NSCLC.
This prospective, single-centre trial evaluated ⁶⁸Ga-NOTA-GSI PET/CT after two treatment cycles in 41 patients with stage IIIB/IV non-small cell lung cancer receiving immunotherapy.
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.
Multiple Radioiodine-avid Skin Metastases From Thyroid Carcinoma Detected on Posttherapy 131 I SPECT/CT.
A 77-year-old man with papillary thyroid carcinoma had achieved remission after radioactive iodine treatment for metastatic disease.
Multitarget Molecular Imaging-based Characterization of Gastrointestinal Stromal Tumor.
An incidental gastric gastrointestinal stromal tumor (GIST) was identified and evaluated using three separate PET radiopharmaceuticals.
PSMA Radio-guided Surgery to Identify Lymph Node Metastases in Prostate Cancer Patients Undergoing Robot-assisted Radical Prostatectomy and Extended Pelvic Lymph Node Dissection: Results of a Phase 2 Prospective Study.
This prospective phase 2 study assessed the feasibility and diagnostic performance of PSMA radio-guided surgery during robot-assisted radical prostatectomy and extended pelvic lymph node dissection in men with localized…
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…

This prospective, single-centre, single-arm pilot study evaluated combined [177Lu]Lu-DOTATATE and [177Lu]Lu-DOTA-IBA in 30 patients with neuroendocrine neoplasms and bone metastases.
From static to dynamic SPECT/CT: A systematic review of clinical applications and perspectives.
This systematic review evaluates the clinical applications of dynamic SPECT/CT across various organ systems, particularly in cardiology and nephrology.
Efficacy of redifferentiation therapy in radioactive iodine refractory thyroid cancer: a systematic review and meta-analysis.
This systematic review and meta-analysis assessed targeted redifferentiation therapy in patients with radioactive iodine (RAI)-refractory thyroid cancer.
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.
