- Review pertinent pathophysiology of gastrointestinal stromal tumors - Describe imaging findings of gastrointestinal stromal tumor at presentation with implications on treatment planning/options - Discuss imaging findings following various treatment approaches 

1. Review of gastrointestinal stromal tumors pathophysiology and clinical features a. Activating mutations (KIT and PDGFRA) b. Epidemiology c. Signs and symptoms at presentation 2. CT and MR findings at presentation a. Common sites – GI tract, mesentery and retroperitoneum b. Metastatic disease – hepatic and peritoneal disease c. What do clinicians want to know to plan treatment?     i. Relationship between mass and gastrointestinal wall 3. Post-Treatment studies a. Normal post treatment change versus recurrence 4. Summary - Gastrointestinal stromal tumors are the most common mesenchymal tumors of the GI tract - CT and MRI are the imaging methods of choice for detection, staging, treatment (surgical) planning, and follow-up of gastroinstestinal stromal tumors
