The Value of MRI and CT in the Diagnosis of Retroperitoneal Tumours

Objective: This study aimed to investigate the effectiveness and value of MRI and CT in the diagnosis of retroperitoneal tumours. Methods: 60 patients with retroperitoneal tumours admitted to our hospital between July 2022 and March 2023 were selected as the study subjects. All of them received MRI and CT examinations. The detection of the two examination methods was compared and analyzed using the pathological findings as the standard. Results: The detection rate of MRI (58/60, 96.67%) was significantly higher than that of CT (50/60, 83.33%), and the difference was significant (P = 0.015 < 0.05). Conclusion: Both MRI and CT have important application values in the diagnosis of retroperitoneal tumours. MRI has advantages in observing soft tissue structures, nerve tissues, etc., and can provide more detailed anatomical structure information, which can help differentiate the retroperitoneal tumours and locate them accurately. CT, on the other hand, has unique advantages in observing the skeletal structure and the density of certain tumours, etc. It can quickly obtain comprehensive imaging information, which helps to determine the extent and invasion of the tumour.
