ABSTRACT
Objective To analyze the MRI characteristics of hematospermia seminal vesiculitis(HSV) and evaluate the diagnostic value of MRI in HSV. Methods The MRI parameters of 25 HSV patients underwent magnetic resonance imaging(MRI) imaging with SE T 1WI(TR/TE 558/14ms), Flash 2D water excitement(TR/TE 18.5/5.2ms), TSE T 2WI(TR/TE 4000/99ms) and fat suppression sequences were retrospectively analyzed. Results The bilateral seminal vesicles in all 25 patients with HSV enlarged. On SE T1-weighted images, intraseminal vesicle hemorrhage appeared as high signal intensity, which appeared more bright on Flash 2D water excitement sequence. The hypointensive duct wall of seminal vesicles could be clearly seen because of hyperintensive hemorrhage. On TSE T2-weighted images, intraseminal vesicle hemorrhage appeared as relatively lower signal intensity, and the duct wall of seminal vesicles could not clearly be depicted for being covered with relatively hypointensive hemorrhage. Conclusion Hematospermia seminal vesiculitis could be identified by MRI, and MRI was the best imaging method for examining hematospermia seminal vesiculitis.
