Objective: To assess the diagnostic efficacy of computed tomography (CT) and magnetic resonance imaging (MRI) in detecting cervical lymph node metastasis caused by head and neck cancer.Methods: Studies designed as cohort studies that detecting the diagnostic efficacy of CT and MRI on cervical lymph node metastasis were included.The included studies were required to use the pathologic diagnosis as the reference standard and reported true-positive, false-positive, false-negative, true-negative and related data.MEDLINE (1948 to Jan.25th, 2014), EMBASE (1980 to Jan.25th, 2014), China National Knowledge Infrastructure (1994 to Jan 25th,2014), VIP (1989 to Jan.25th, 2014) and Wang fang databases (1998 to Jan.25th, 2014) were electronically searched to retrieve any possibly related studies.Two reviewers independently conducted the study inclusion, data extraction, and assessment of the quality (via the Quality Assessment Diagnostic Accuracy Studies statement-2 (QUADS-2)).Meta-disc 1.4 and STATA 11.0 were used to conduct the statistical-analysis.
