About

This study aims to compare weight-bearing Cone Beam CT arthrogram and conventional CT arthrogram in assessement of patients with ankle osteo-chondral or cartilage lesions.

Full description

Weight-bearing Cone Beam CT (CBCT) arthrogram, a technique with less radiation dose than conventional CT, is hypothesized non-inferior to conventional CT arthrogram to diagnose osteo-chondral (OCL) or cartilage lesions of the ankle.
