Other Imaging Modalities
MRI with gadolinium has also been used for gastric cancer staging. It is similar to CT in its advantages (ability to find distant metastases) and weaknesses (need for adequate gastric distention). The accuracy of MRI ranges from 90% to 93% for T staging and from 91% to 100% for N staging.340 However, given the small number of studies, MRI cannot yet be advocated as the test of choice for staging gastric cancer.
