Accurate preoperative staging of gastric cancer is of major importance for guiding therapeutic decision-making, preventing both under- and over-treatment. The purpose of this study is to investigate the diagnostic performance of the Multi-parametric magnetic resonance imaging (mpMRI) and dual-energy computed tomography (DECT) in gastric cancer.
Consecutive patients with preoperative pathologically confirmed GC by endoscopy and preoperative imaging data (DECT/mpMRI) were included.
No contraindications for CT/MRI examination
Written informed consent
Patients with a history of previous therapy.
Patients with recurrent gastric cancer
Patients with a history of severe allergy to contrast agents
Patients with imaging artefacts affect the evaluation
