Reconversion of bone marrow is a reverse process of natural replacement of red marrow by yellow marrow. 23 with insufficiency fracture of the knee, a condition previously called spontaneous osteonecrosis of the knee (sonk), there is signal abnormality in the region of 40% fat, 40% water and 20% protein. The previously abnormal region of bone marrow that did not show signal dropout on prior opposed-phase imaging now showed partial return to normal marrow signal (Fig. Does abnormal bone marrow signal on MRI always indicate malignancy? Doctors can use a bone marrow biopsy test to identify cancer cells and diagnose a metastasis. Signal characteristics of bone marrow include: T1: red marrow: hypointense to subcutaneous fat, but hyperintense to muscle and disc (due to scattered fat cells) yellow marrow: hyperintense (follows the signal of subcutaneous fat).

Required fields are marked *. Bone marrow edema (BME) is one of the most common findings on magnetic resonance imaging (MRI) after an ankle injury but can be present even without a history of trauma. Magnetic resonance imaging (MRI) after ankle trauma often shows alteration of bone marrow signal with a low signal on T1-weighted and a high signal on T2-weighted and fluid-sensitive sequences (like short tau inversion-recovery (STIR) or fat-suppressed (FS) sequences). MRI examination demonstrated abnormal signals in the bone marrow in large areas of the right pelvis, indicating increased water content and a decreased proportion of fat. Address correspondence to C.

Both CT and MRI have high accuracy for the detection of osteochondral lesions. IMPRESSION: Diffusely heterogeneous bone marrow, without evidence of discrete destructive process. Red bone marrow reconversion refers to the process of mature yellow marrow being replaced by hematopoietic red marrow. The abnormal signal is due to replacement of the small amounts of fat cells normally found in red marrow, such that T1 signal will decrease to or below the signal from disc or muscle.
