CT Texture Analysis of Cervical Lymph Nodes on Contrast-Enhanced 18F FDG-PET/CT Images to Differentiate Nodal Metastases from Reactive Lymphadenopathy in HIV-Positive Patients with Head and Neck Squamous Cell Carcinoma

摘要

Differentiating nodal metastases from reactive adenopathy in HIV-infected patients with [ F] FDG-PET/CT can be challenging because lymph nodes in HIV-positive patients often show increased [ F] FDG uptake. The purpose of this study was to assess CT textural analysis characteristics of HIV-positive and HIV-negative lymph nodes on [ F] FDG-PET/CT to differentiate nodal metastases from disease-specific nodal reactivity.
