Seven studies met the inclusion criteria (n=405). The authors stated that a test for between-study heterogeneity was not significant.
Endoscopic ultrasound: Sensitivity ranged from 80% to 100%, specificity ranged from 50% to 99% and accuracy ranged from 93% to 96%.
MRCP: Sensitivity ranged from 40% to 100%, specificity ranged from 72% to 97% and accuracy ranged from 82% to 94%.
The diagnostic performance of MRCP was generally slightly inferior to that of endoscopic ultrasound. Odds ratios were 0.34 (95% CI 0.17 to 0.70) for sensitivity, 0.78 (95% CI 0.35 to 1.73) for specificity and 0.79 (95% CI 0.47 to 1.32) for accuracy.
