Corrections 1. In the article titled, “Pitfalls in the Imaging and Interpretation of Benign Thymic Lesions: How Thymic MRI Can Help,” which appeared in the January online issue of AJR (AJR 2016; 206:W1–W8), there was an error in the formula on page W2. The correct formula should be CSR = (thymus OP / muscle OP) / (thymus IP / muscle IP). DOI:10.2214/AJR.16.16084
