18F-FDG PET-CT is a sensitive method for detecting, staging, and monitoring the effects of therapy of many tumors. In the evaluation of malignancy with 18F-FDG, a potential pitfall in the assessment of the anterior mediastinum is mistaking normal uptake within the thymus from disease such as adenopathy or local invasion by tumor. Thymic uptake was classified as "normal" on the basis of morphologic features, size, and contour at 18F-FDG PET. The standardized uptake value (SUV) to measure 18F-FDG uptake may be useful in evaluating the differentiation of thymic carcinoma from other thymic neoplasm, and hyperplasia.

Abstract
18F-FDG PET-CT is a sensitive method for detecting, staging, and monitoring the effects of therapy of many tumors. In the evaluation of malignancy with 18F-FDG, a potential pitfall in the assessment of the anterior mediastinum is mistaking normal uptake within the thymus from disease such as adenopathy or local invasion by tumor. Thymic uptake was classified as "normal" on the basis of morphologic features, size, and contour at 18F-FDG PET. The standardized uptake value (SUV) to measure 18F-FDG uptake may be useful in evaluating the differentiation of thymic carcinoma from other thymic neoplasm, and hyperplasia.
