MR images of healthy young subject with normal red bone marrow. a The bone marrow appears hypointense on T1-weighted images (left), without focal lesions and with a corresponding high signal intensity on fat-suppressed T2-weighted images (right). b There is a high signal intensity on b1000 images due to the low amount of fat cells, high cellularity (hematopoietic cells) and high amount of water. c The vascularization and perfusion are also high (TIC type 4), with an early wash-out of contrast medium
