Sialolithiasis: MR sialography of the submandibular duct--an alternative to conventional sialography and US?
PURPOSE To determine the value of magnetic resonance ( MR ) sialography for the diagnosis of sialolithiasis by comparing results prospect ively with those of ultrasonography ( US ) and digital sialography . MATERIAL S AND METHODS MR sialography was prospect ively performed with T2-weighted three-dimensional ( 3D ) constructive interference in steady-state ( CISS ) and rapid acquisition with relaxation-enhancement ( RARE ) sequences in 24 patients suspected of having sialolithiasis . Evoked salivation was used as contrast material . T1-weighted spin-echo and T2-weighted turbo spin-echo MR imaging also were performed . The results were then compared with those of US and digital sialography , with the latter as st and ard of reference . RESULTS The 3D CISS images were significantly ( P : < .05 ) superior to RARE images for demonstrating the subm and ibular ductal system , followed by T2-weighted turbo spin-echo images ( P : < .01 ) and T1-weighted spin-echo images ( P : < .001 ) . The sensitivity and specificity were 100 % and 80 % , respectively , for CISS MR sialography and 80 % and 100 % , respectively , for RARE MR imaging . The sensitivity and specificity of US were both 80 % . CONCLUSION MR sialography with evoked salivation is noninvasive and allows delineation of the subm and ibular ductal system and detection of sialoliths with accuracy that is similar to that of digital sialography and superior to that of US
