Imaging of the GIST

Introduction: Gastrointestinal stromal tumours (GISTs) are mesenchímal tumours of the digestive tract. These tumours represent 0.1–3% of all gastrointestinal neoplasms. These tumors can arise anywhere in the gastrointestinal tract, but most often in the stomach (70%). They are diagnosed sometimes as accidentally findings, but in the other cases they occour as urgent problems in the gastroenterology such as abdominal pain and bleeding. 10–30% of the newly diagnosed GIST are malignant. The imaging methods can predict the answer for these questions and help the managment of the following strategies in this type of the gastrointestinal tumours.
