title: Imaging spectrum of gastrointestinal stromal tumor.
abstract: Gastrointestinal stromal tumors (GISTs) were first described by Clark and Mazur in 1983 for smooth muscle neoplasms of the gastrointestinal tract differentiating them from leiomyoma, leiomyosarcomas and neurogenic tumors. GISTs can arise from the bowel, peritoneum, omentum or retroperitoneum. This article reviews the computed tomography imaging features of primary GISTs, response to treatment and highlights data on predicting the outcome to chemotherapeutic drugs on imaging.
