The diagnostic performance of PET-CT or PET in pre-operative M staging in CRC patients was illustrated. A, B. Revealed that the forest plot of pooled sensitivity and specificity of ¹⁸F-FDG PET-CT or PET in pre-operative M staging in CRC patients, respectively. C. Illustrated the SROC curve of ¹⁸F-FDG PET-CT or PET in pre-operative M staging in CRC patients. AUC, area under the curve; CRC, colorectal cancer; ¹⁸F-FDG, Fluorine-18 fluorodeoxyglucose; PET, Positron Emission Tomography; CT, computed tomography; SROC, summary receiver operating characteristic.
