PDFAbstract
Objective To explore The diagnostic value of combined diffusion-weighted MRI with conventional MRI in undescended testes. Methods 18 cases confirmed undescended testes by clinical surgery and pathology were retrospectively analyzed, all patients were performed routine T1WI, T2WI-FS, enhancement and DWI. Double blind evaluation and calculation of routine MR sequences, enhancement and DWI were adopted for diagnostic sensitivity, specificity and accuracy examination of nonpalpable undescended testis. Results The findings of the cryptorchidism were long T1, long T2 signal with clear edge, high signal intensity on DWI. With the combined application of T1WI, T2WI-FS, enhancement and DWI, the sensitivity and accuracy were respectively 94% and 94, higher than that of single application of conventional MRI examination. Conclusion the combined use of T1WI、T2Wl-FS, enhancement and DWI is helpful to improve the accuracy of impalpable testis on localization and diagnosis.
