Sagittal planning
- Cover from the inferior cortex of the fifth metatarsal to mid-calf.
- Angle perpendicular to the long axis of the tendon.

MSK protocol
Ankle MRI
Ankle MRI for plantar fasciitis, bone and soft tissue infection or neoplasm, avascular necrosis, sinus tarsi syndrome, and congenital and developmental conditions. Standard three-plane protocol with sagittal coverage from the fifth metatarsal to mid-calf, angled perpendicular to the long axis of the tendon. Routinely performed without contrast.

axial
Axial planning
- Cover from the inferior cortex of the fifth metatarsal upward as far as possible.
- Align perpendicular to the tibia and fibula (sagittal view).
- Cover the talofibular joint through the calcaneus.

coronal
Coronal planning
- Cover the plantar (inferior) soft tissues.
- Align parallel to the tibia.
- Cover from the Achilles tendon to the base of the metatarsals.
