Conditions
Summary
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.
Eligibility
Inclusion Criteria3
- 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
Exclusion Criteria4
- 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
Interventions
DECT examinations will be performed using a 192-slice CT scanner (SOMATOM, Force, Siemens, Forchheim, Germany).
The examinations were conducted on a 3-T MR scanner (MAGNETOM Skyra; Siemens Healthcare, Erlangen, Germany).
