[Gastric lymphoma: diagnostic radiology in the staging of the disease].

Abstract

In the staging of gastric lymphoma, the radiologist has very important role, because he has many means to define correctly the stage. Conventional radiology is useful for detection of the lesion. Moreover, Ultrasound, Computed Tomography, and Magnetic Resonance are useful to define parietal extension and eventual nodal involvement. Lymphography remains a study kept to negative or doubt cases. In the future, the Magnetic Resonance will have a bigger role than now, in the definition of abdominal and pelvis nodal involvement.
