Abstract:
Objective To explore 18F-FDG PET-CT in the detection of malignant tumors of the gastrointestinal tract.Methods 39 patients with gastrointestinal tumors who was diagnosed with operation,pathological examination,clinical and imaging follow-up undertake the whole-body 18F-FDG PET-CT.Results The sensitivity and specificity were both 100.0 ％ for primary malignant tumors.Gastric metastases sensitivity,specificity and accuracy were 80.0 ％ (4/5),90.9 ％ (10/11),87.5 ％ (14/16),and the colorectal metastases sensitivity,specificity,accuracy of diagnostic results were 88.9 ％ (8/9),92.9 ％ (13/14),91.3 ％ (21/23).The gastric cancer lymph node metastasis sensitivity,specificity and accuracy were 50.0 ％ (3/6),90.0 ％ (9/10),75.0 ％ (12/16),in the diagnosis of colorectal local lymph node metastasis the sensitivity,specificity and accuracy were 71.4 ％ (5/7),93.8 ％ (15/16),87.0 ％ (20/23).Conclusion The 18F-FDG PET-CT imaging for gastrointestinal malignant tumor diagnosis and residual lesions recurrence or lesions metastases of detection is of important value and better than traditional examination methods.
