Figure 1 T2-weighted image correlation data for coracoclavicular (CC) ligament magnetic resonance imaging (MRI). (A) Measurement of the length of the CC ligament on T2-weighted MRI. (B) Sagittal coracoclavicular ligament length measurement on T2-weighted MRI. (C) Measurement of the distance from the supraclavicular plane to the subcoracoid plane on T2-weighted MRI. Point a: The central point of the CC ligament at the clavicular attachment. Point b: The CC ligament at the center of the CC attachment. Point d: The CC ligament at the center of the clavicular attachment. Point e: The CC ligament at the coracoid attachment point. Point k: The point of the supraclavicular plane through the CC ligament. Point l: The point of the subcoracoid plane through the CC ligament the length of the CC ligament. ab: The length of the CC ligament in the coronal plane. de: The length of the CC ligament in the sagittal plane. kl: The distance between the supraclavicular plane of the CC ligament and the subcoracoid process plane.
