[Retracted] CT and MRI Imaging Characteristics of Gastrointestinal and Mesangial Reactive Nodular Fibrous Pseudotumor Based on Virtual Reality

Abstract

In recent years, with the continued development and development of science and technology and the increasing maturity of medical technology, reactive nodular fibrous pseudotumors remain difficult to diagnose. Therefore, this paper studies CT and MRI imaging properties based on hypothetical gastrointestinal and mesangial reactive erythema nodosum fibrous pseudotumors to improve the diagnosis and treatment of reactive nodular fibrous pseudotumors. In this study, 48 patients with gastrointestinal and intermediate-reactive erythema nodosum fibrous pseudotumors in the gastrointestinal tract and experimental group were screened and identified by surgical pathology and immunohistochemistry. CT or magnetic resonance imaging was used in all patients. An analysis is performed, and the diagnostic values are compared with the pathological results. Experiments have proved that the postoperative reexamination of reactive nodular fibrous pseudotumors found that single masses are common, tumor sizes are different, and most small nodules have relatively more uniform lesion density, and the density of the plain scan is close to the muscle density, and the delay can be seen after enhancement. When the mass is large, the density is uniform, and low-density foci of different degrees can be seen in some masses, and this part rarely shows enhancement. The imaging phenomenon and clinical features of reactive nodular fibrous pseudotumors have specific features that distinguish them from invasive tumors such as gastrointestinal stromal tumors and provide an important basis for accurate clinical diagnosis and treatment.
