摘要: The malignant potential of gastrointestinal stromal tumors (GISTs) is difficult to diagnose before surgery because the diagnoses are based on tumor diameter and mitotic index. progression small GISTs always observed they do not seem have potential. 18F-Fluorodeoxyglucose (FDG)-positron emission tomography (PET) a useful technique for assessing activity. objective this study was determine if FDG-PET predicting gastric GISTs. Ten patients diagnosed with participated. performed all them resection. A whole-body image initiated 40 minutes after injection 275 370 MBq FDG. FDG uptake assessed by standardized value. All had uptake. There significant correlation between both Ki67 index but diameter. correlation. may be considerable value surgery. GIST high should regarded as having
