Cone Beam CT (CBCT) Arthrogram of the Ankle in Assessement of Osteochondral or Cartilage Lesions

N/ACompletedNCT05203757

Assistance Publique - Hôpitaux de Paris35 enrolled

Overview

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.

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.
