ARTICLE HIGHLIGHTS

Research background

The malignant tendency and complex features of gastric stromal tumors (GSTs) seriously threaten human health.

Research motivation

Multi-slice spiral computed tomography (MSCT) is widely used in clinical practice. We try to apply it in the differential diagnosis and risk stratification of GSTs and benign gastric polyps, hoping to obtain valuable clues that can guide the clinical practice.

Research objectives

This study aimed to clarify the manifestations of GSTs and benign gastric polyps in multi-slice computed tomography, including diagnostic value and risk stratification.

Research methods

The differences and risk stratification characteristics of MSCT imaging parameters and contrast-enhanced CT between patients with GST confirmed by pathological examination after surgery and patients with benign gastric polyps were retrospectively analyzed.

Research results

There are significant differences in MSCT characteristics and enhancement characteristics between GST and gastric polyps, and the MSCT characteristics and enhancement characteristics of GST in different risk stratifications are also different. MSCT has higher value in the identification and risk stratification of GST and gastric polyps.

Research conclusions

Preoperative application of MSCT to distinguish GST from benign gastric polyps is of high value, and it is also feasible to classify the risk level of GST patients.

Research perspectives

We recommend preoperative MSCT to distinguish GST from benign gastric polyps and to classify GST patients at risk.
