Abstract

Objective To compare and analyze the clinical diagnostic efficacy of multi-slice spiral computed tomography(MSCT) and MRI for early occult fractures. Methods A retrospective analysis was conducted on the clinical data of 120 patients with lower limb occult fractures admitted to the 940th Hospital of PLA Joint Logistics Support Force from January 1, 2020 to December 31, 2024. Among them, 75 were males and 45 were females, with ages ranging from 15 to 55 years old, and the injury time was 3 to 72 hours. All patients underwent both CT and MRI examinations simultaneously. Through a double-blind method, the diagnostic accuracy of 3.0T MRI and MSCT for the location of lower limb occult fractures was evaluated, and the imaging manifestations of MRI and MSCT for lower limb occult fractures were analyzed. Results The detection rate of MRI for lower limb occult fractures was 95%, which was higher than that of MSCT(88.33%), especially more prominent in long bone fractures. The diagnostic accuracy rate of MRI for tibial occult fractures was 100%, followed by metatarsal/phalangeal(95.45%), fibular(94.74%), and femoral fractures(92.86%). Conclusions MRI demonstrates higher accuracy in the early precise diagnosis of occult fractures, and is significantly superior to MSCT in clearly revealing the range and degree of bone marrow edema around the fractures, which can provide great assistance for clinical precise diagnosis and the selection of personalized treatment plans.
