High-Resolution Oblique Coronal MRI with Optimal Flexed-Knee Angle for Anterior Cruciate Ligament Tear Diagnosis

Motivation: Anterior cruciate ligament (ACL) injuries are prevalent in the realm of knee injuries. Conventional MRI methodologies employed for diagnosing ACL tears exhibit low accuracy. Goal(s): Evaluate the diagnostic efficacy of high-resolution coronal MRI performed at an optimal flexion angle specifically for ACL tears. Approach: Healthy volunteers and patients are scanned to find the optimal flexion angle and compare the image quality with traditional extended-knee positioning approach. Results: The implementation of high-resolution coronal imaging at the ideal flexion angle (30 degrees) has the potential to enhance ACL visualization and improve diagnostic accuracy when compared with conventional techniques. Impact: The utilization of high-resolution coronal imaging at the optimal flexion angle (30 degrees) demonstrated a substantial enhancement in the visualization of the anterior cruciate ligament (ACL), resulting in a notable improvement in diagnostic accuracy as compared to conventional techniques.
