Official title
Diagnostic and Predictive Performance of Dual-/ Muti- Energy CT and MRI in the Treatment Response and Survival Prognosis of Gastric Cancer
Overview
Accurate preoperative prediction of risk stratification, treatment response, and survival prognosis in gastric cancer is important for improving clinical treatment decisions, prolonging patient survival, and improving patient quality of life. The purpose of this study is to investigate the performance of the multi-parametric magnetic resonance imaging (mpMRI) and Dual-/Muti-energy CT and photon-counting Detector CT(PCD-CT) in the diagnosis and management of gastric cancer.
Interventions
- Device computerized tomography
mpMRI and Photon-counting Detector CT scan
Primary outcome measures
- Diagnostic and Predictive performance of Dual-/ Muti- energy CT and MRI in the treatment response and survival prognosis of gastric cancer [Time frame: 3years]
Secondary outcome measures (1)
- The kappa value; One-way analysis of variance; ICC [Time frame: 1year]
Eligibility criteria
Inclusion criteria
- Pathological biopsy confirmed gastric cancer;
- Surgery: patients undergoing radical gastrectomy. Patients undergoing exploratory abdominal surgery or palliative tumor resection were still included in the study when peritoneal metastasis or adjacent organ invasion was identified intraoperatively and radical surgical resection was not possible.
Exclusion criteria
- Refusal or inability to sign informed consent;
- CT or MRI images are poor or the focus is small and CT images are not clear;
- Patients with other tumors complicated with patients with important organ dysfunction.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
Healthy volunteers: No
