Title: Diagnostic Value of Magnetic Resonance Diffusion-weighted Imaging Combined with Conventional MRI for Abdominopelvic Abscess
Abstract: Objective:To explore the MR findings of abdominopelvic abscess in order to improve diagnostic level.Methods:Retrospective analysis and summarization of the MR findings of 15 cases with abdominopelvic abscesses were made.All cases underwent T1WI,T2WI and DWI examinations.Results:A total of 22 lesions in 15 cases were studied.①Position:32% lesions (7/22) were located in right paracolic gutter,27% lesions (6/22) in subphrenic space and 18% (4/22) in women pelvic cavity;②Shape:68% lesions (15/22) were round or round-like,86% lesions (19/22) had capsule,23% lesions (5/22) had septation;③Signal:Early stage of the abscess-formation:8 lesions in 5 cases.In this stage,the signal of abscess cavity on T1WI was low and on T2WI was high;3 lesions had high-signal on DWI,and 5 lesions had low-signal;The capsules were incomplete or absent,their signal was low or equal on T1WI and low on T2WI.There was effusion around the lesions,with obscure boundary.Typical stage and late stage of abscess-formation:14 lesions in 10 cases,the signal on T1WI was low,on T2WI and DWI was high or slightly high;when capsules were complete,the peplos signals were low on T1WI and T2WI.All lesions had a clear boundary or relatively clear boundary;the intestine or omentum might gather together.Conclusion:DWI and common MRI are helpful in diagnosing abdominopelvic abscess.
