What imaging modality is preferred for the initial evaluation of the suspensory ligament?

• A. Radiographs
• B. Ultrasound
• C. MRI
• D. CT

Answer: (B)

Ultrasound is the best initial imaging for evaluating a suspensory ligament because it directly visualizes soft-tissue structures along the ligament’s entire course, allowing assessment of fiber integrity, thickening, and edema in real time. It can detect fiber disruption, hypoechoic or heterogeneous areas indicating tears, and nearby fluid or sheath involvement, all in a dynamic, radiation-free exam that’s quick and easily repeatable to monitor healing. Radiographs mainly show bone and are not sensitive for ligament injuries. MRI offers superior soft-tissue detail but is more costly and less available for initial evaluation, while CT is oriented more toward bone assessment and rarely used first for ligament injuries.
