Diagnostic efficacy of [F]FDG PET/CT and [F]FDG PET/MRI in preoperative staging of locoregional urinary bladder cancer: a systematic review and Meta-Analysis.

Background: This systematic review and meta-analysis aims to evaluate the diagnostic utility of [F]Fluorodeoxyglucose ([F]FDG) PET/CT and [F]FDG PET/MRI in preoperative locoregional staging of bladder cancer (BC).

Methods: A comprehensive search of PubMed and Scopus databases was conducted up to February 26, 2025, to collect and analyze diagnostic accuracy parameters. Statistical analyses, including publication bias assessment, interstudy heterogeneity evaluation, and effect size adjustment, were performed using Stata software, with a significance threshold set at p < 0.

Short-term Prostate-specific Antigen Pseudoregression Following [ 177 Lu]-Prostate-specific Membrane Antigen Therapy : Tackling Prostate-specific Antigen Decline Limitations in Patient With Metastatic Castration-resistant Prostate Cancer.

A 74-year-old man with metastatic castration-resistant prostate cancer underwent 2 cycles of [ 177 Lu]Lu-prostate-specific membrane antigen (PSMA) therapy. Despite declining prostate-specific antigen (PSA) levels and pain relief throughout the first 4 months of [ 177 Lu]Lu-PSMA therapy, follow-up [ 68 Ga]Ga-PSMA PET/CT revealed progressive skeletal involvement. A bone marrow biopsy confirmed fulminant metastatic castration-resistant prostate cancer infiltration.

Diagnostic pitfalls in [68Ga]Ga-DOTATATE PET/CT imaging: a systematic review.

[68Ga]Ga-DOTA-Tyr3-octreotate ([68Ga]Ga-DOTATATE) is an established somatostatin receptor imaging agent that has demonstrated superior efficacy in visualizing neuroendocrine tumors (NETs) and meningiomas compared with traditional [ 111 In]In-octreotide imaging. Despite its enhanced affinity and sensitivity, [68Ga]Ga-DOTATATE imaging is not without challenges. To date, numerous diagnostic pitfalls and false-positive findings have been reported.

Beyond CT: A Case Analysis of Serial [18F]FDG PET/CT for Assessment of Necrosis and Early Recurrence in Colorectal Liver Metastases.

Colorectal cancer is a common malignancy, with the liver being the most frequent site of metastases. [F] Fluorodeoxyglucose ([F]FDG) positron emission tomography/computed tomography (PET/CT) has emerged as a valuable tool in detecting and evaluating liver metastases and extrahepatic disease. Herein, we present a case of a 76-year-old male with colorectal cancer associated with lung and liver metastases.

68 Ga-FAPI PET/CT Imaging : Unveiling the Hidden Pitfalls.

68 Ga-FAPI has been introduced recently in many nuclear medicine centers. Many pitfalls have been discussed previously. However, not all pitfalls are currently addressed in the literature.
