What this trial studies

This observational study aims to evaluate the effectiveness of multi-parametric magnetic resonance imaging (mpMRI) and dual-energy computed tomography (DECT) in accurately staging gastric cancer before surgery. Gastric cancer is a leading cause of cancer-related deaths, and precise staging is crucial for determining the appropriate treatment. The study will include patients with confirmed gastric cancer who have not undergone prior therapy, utilizing advanced imaging techniques to enhance diagnostic accuracy. The findings could lead to improved individualized treatment plans based on more reliable staging results.

Who should consider this trial

Good fit: Ideal candidates are patients with preoperative pathologically confirmed gastric cancer who have not received prior treatment.

Not a fit: Patients with recurrent gastric cancer or those who have previously undergone therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate preoperative staging of gastric cancer, allowing for better treatment decisions and improved patient outcomes.

How similar studies have performed: While the use of DECT and mpMRI in gastric cancer staging is gaining traction, this study explores their combined diagnostic performance, making it a novel approach.
