Detection of lesions confined to bone marrow by MRI in a 38 year old female known case of leukemia- CT bone window image (A) shows no abnormality. MR images demonstrate altered marrow signal intensity with few areas appearing hypointense on T1W (B) and hyperintense on T2W (C) images, showing enhancement on post contrast T1W images (D). These lesions represent leukemic infiltrates which were not picked up by CT
