Analysis of the clinical value of multi-slice spiral computed tomography (MSCT), magnetic resonance imaging (MRI) and ultrasound (US) in the diagnosis of retroperitoneal tumors

Abstract

Retroperitoneal tumors are tumors that originate in the retroperitoneal space (including retroperitoneal fat, connective tissue, fascia, blood vessels, muscles, nerves, lymph and embryonic residual tissues). Because the tumor grows deep, it is affected by organs in the abdominal cavity, and the symptoms are hidden, the patient s condition has been relatively severe at the time of consultation (1). The clinical incidence of retroperitoneal tumors is not high, but 85% of tumors that occur retroperitoneally are malignant (2,3). The retroperitoneal cavity has a complex anatomical structure and a wide range of involvement, which is difficult to detect early, but early detection and effective treatment are of great significance for prognosis and can improve Original Article
