Multi-parametric MRI and Dual-energy CT in Patients of Gastric Cancer

Condition(s) studied

Investigational drug(s) / intervention(s)

DECT examination: DECT examinations will be performed using a 192-slice CT scanner (SOMATOM, Force, Siemens, Forchheim, Germany).

mpMRI examination: The examinations were conducted on a 3-T MR scanner (MAGNETOM Skyra; Siemens Healthcare, Erlangen, Germany).

Study 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

Primary outcome measure(s)

• Diagnostic performance of DECT and mpMRI in tumor staging assessment — 2 years
  Accuracy for both imaging techniques in the prediction of tumor staging.
• Diagnostic performance of DECT and mpMRI in tumor restaging assessment — 2 years
  Accuracy for both imaging techniques in the prediction of tumor restaging.
