Abstract: This paper explored the value of multi-slice spiral CT (MSCT) combined with magnetic resonance imaging (MRI) in the diagnosis of knee injuries in marathon runners. 95 patients with knee injuries of marathon runners were selected as research subjects, and all underwent MSCT and MRI examinations. The results showed that with the results of arthroscopy or surgery as the "gold standard", the accuracy rates of MSCT and MRI alone in diagnosing the types of knee injuries in marathon runners were 86.32% and 93.68%, respectively, and the accuracy rate of combined diagnosis reached 100.00%. The Kappa values of MSCT combined with MRI for the grading of knee ligament injury, meniscus injury and the results of arthroscopy or surgery were 0.944 and 0.933, respectively. Compared with the results of arthroscopy or surgery, the accuracy of MSCT combined with MRI to diagnose occult knee fractures in marathon runners is 100.00%. It can be seen that MSCT combined with MRI imaging technology has a high accuracy in diagnosing the types of knee injuries in marathon runners, and can further accurately assess the classification of knee ligament injury, meniscus injury, and occult fracture sites.
