Overview
This study explores the efficacy of Ga-68-PentixaFor PET/CT in detecting, assessing treatment response, and monitoring the risk of aggressiveness in indolent B-cell lymphoma. The background introduces CXCR4 and discusses its role in cancer research. Currently, FDG-PET is the primary imaging tool for lymphoma staging, but it lacks diagnostic accuracy for low-grade lymphomas. Ga-68-PentixaFor PET demonstrates promising detection capabilities across various lymphomas, suggesting its potential as a superior imaging modality for low-grade lymphomas.
