From: High-resolution axial MR imaging of tibial stress injuries

High-resolution axial MR imaging of Group 1. Top: Case A showing abnormal periosteal signals along the medial surface of the tibia. High-resolution MR imaging shows abnormal signals along the anterior-medial aspect of the tibial bone marrow. Middle: Case B showing abnormal periosteal signals along the medial and medial posterior surface of the tibia. MR imaging shows abnormal signals in medial-posterior part of the tibial bone marrow, but never extends to the entire bone marrow. Bottom: Case C showing abnormal periosteal signals along the posterior surface of the tibia. MR imaging shows abnormal signals in anterior-medial part of the tibial bone marrow.
