CXCR4-targeted PET/CT Imaging in Hematological Malignancies

Sponsor: Zhongnan Hospital

Summary

Hematological malignancies continue to pose significant clinical challenges due to their high incidence, heterogeneous biology, and substantial mortality. Although 18F-FDG PET/CT remains the most commonly used molecular imaging modality, its limited specificity can result in false-positive or false-negative findings, especially in indolent or low-metabolism subtypes, thereby hampering accurate diagnosis, staging, and therapeutic evaluation. C-X-C chemokine receptor type 4 (CXCR4) is frequently overexpressed in a broad spectrum of hematologic malignancies and correlates with aggressive disease and unfavorable outcomes. CXCR4-targeted molecular imaging using \^68Ga-pentixafor PET/CT has shown promise for improved disease characterization. This prospective study aims to systematically compare 68Ga-pentixafor PET/CT with 18F-FDG PET/CT in terms of diagnostic performance, staging accuracy, risk stratification, and prognostic relevance in patients with hematological malignancies. Furthermore, the study will incorporate artificial intelligence-based image analysis to enhance lesion detection, automate quantitative assessments, and support personalized clinical decision-making.
