Diagnostic Performance of [ ¹⁸ F]FDG PET/MRI and [ ¹⁸ F]FDG PET/CT in the Detection of Lymph Node Metastases in Colorectal Cancer: A Meta-analysis.

ABSTRACT:

Background

Colorectal cancer (CRC) ranks among the leading causes of cancer-related mortality worldwide. Accurate detection of lymph node metastases plays a crucial role in determining disease stage and guiding treatment decisions. Fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) and 18F-FDG PET/magnetic resonance imaging (MRI) are advanced imaging modalities widely used in clinical practice. The study aimed to compare the diagnostic accuracy of [ ¹⁸ F]FDG PET/CT and [ ¹⁸ F]FDG PET/MRI in detecting lymph node metastases in CRC patients.

Methods

A comprehensive literature search was conducted across PubMed, Embase, and Web of Science databases to identify relevant studies published up to February 2025.
