Dear colleagues!

We offer you the opportunity to use the instrument developed by us in order to determine the probability of the tumor being a GIST or leiomyoma. Our prognostic model, built using binary logistic regression, serves as the basis for the calculations.

In order to help us determine the prognosis, please insert the correct values in the table below.

Specify your answers below:
Hypovascular zones:	absent present
Localisation:	EGJ / cardia / fundus of stomach antrum / pylorus / body of stomach
Patient’s age (full years):
Lesion density during the venous phase:
Density in portal vein:
