Motivation: Osteochondral lesions of the talus (OLT) can cause significant joint issues, yet CT’s radiation limits its use in vulnerable populations.
Goal(s): To evaluate the feasibility of 7T zero echo time (ZTE) MRI for OLT evaluation.
Approach: OLT patients underwent CT and 7T ZTE MRI examinations. The assessment of lesions using CT and ZTE involves the detection, localization, classification, and measurement of the lesions. The image quality and description of bone structure were compared using Likert 5-point scoring system.
Results: Compared with CT, 7T ZTE MRI can provide comparable lesion information, suggesting its potential as a radiation-free alternative for OLT evaluation.
Impact: This research paves the way for non-invasive, radiation-free imaging of OLT, enhancing surgical planning and patient safety. Future investigations can explore ZTE’s application in other joint diseases, potentially transforming diagnostic protocols in vulnerable populations.
