We use a checklist when evaluating an MRI of the Ankle: Bones: screen on fatsat images for bone marrow edema. Joints: screen for effusion and look at the joint capsule for thickening.

MRI studies are helpful in determining the size of the lesion, the extent of bony edema, and identify unstable lesions. Treatment can be nonoperative or operative depending on patient age, patient activity demands, lesion size, and stability of lesion.

Although Magnetic Resonance Imaging (MRI) at 1.5 Tesla is the leading cross-sectional modality for detection and staging of OCL, lack of spatial resolution hampers accurate assessment of thin articular cartilage. Cone Beam Computed Tomography (CBCT) arthrography is better suited for precise staging of cartilage lesions.

Diagnosis: Avascular necrosis of talus. T2 weighted images display a typical double line sign which consisting of a hypointense outer line (sclerosis and fibrosis) and a hyperintense inner line (granulation tissue). No fracture could be identified in this case.

Aug 10, 2024 · The talus (plural: tali 4), historically known as the astragalus, is a tarsal bone in the hindfoot that articulates with the tibia, fibula, calcaneus, and navicular bones. It has no muscular attachments and around 60% of its surface is covered by articular cartilage.

Adjacent subtle marrow edema seen in the medial aspect of talus bone. Mild joint effusion is seen at tibio-talar and subtalar joints. These findings most likely represent an osteochondral lesion of talus.

Nov 20, 2012 · The talus is a common site for bone marrow edema on MRI studies. The cause is frequently traumatic because of its key location between the leg and the foot. Other various disease processes such as impingement and inflammatory arthritides can also produce talar bone marrow edema ( Fig. 14 ).

Twenty-five patients had magnetic resonance imaging (MRI) available for review. Based on a literature review and imaging features observed in our patient cohort, a proposed algorithm for differential diagnosis of talar lesions is detailed in Fig. 3. The imaging features of some of the lesions observed in our patient cohort will be reviewed:

Jun 18, 2024 · Talus fractures (other than neck) are rare fractures of the talus that comprise of talar body fractures, lateral process fractures, posterior process fractures, and talar head fractures.

Routine ankle magnetic resonance imaging (MRI) tests involve taking images of the foot and ankle in the axial, coronal, and sagittal planes parallel to the tabletop(2). Axial images are parallel to the long axis of the metatarsal (mid-foot) bones. Coronal images are perpendicular to the long axis of the metatarsals.
