Abstract:
OBJECTIVETo evaluate the accuracy of [18F] fluorodeoxyglucose (FDG) triple-head coincidence imaging in the setting of suspected lung cancer.
METHODS109 patients with suspected lung cancer were enrolled in the present study. According to the diameter of the lesion (> 1.5 cm,
RESULTSOf the total of 109 patients, 86 cases were confirmed as lung cancer whereas 23 cases were benign by pathological study. The sensitivity, specificity and accuracy of FDG imaging were 95% (82/86), 74% (17/23) and 91% (99/109), respectively. For the group of lesion diameter > 1.5 cm, the sensitivity, specificity and accuracy were 98% (81/83)), 63% (10/16) and 92% (91/99), respectively. While for the group of lesion diameter
CONCLUSIONSThe technique of [18F] FDG imaging is an useful method for routine evaluation of patients with suspected lung cancer. The sensitivity of detection is related to lesion size, if lesions
