- W2389678718 abstract "Objective: To study the role of dynamically enhanced magnetic resonance imaging(MRI) in detection of focal liver lesions. Methods: Two handred and twenty three focal liver lesions in 176 patients were proved by pathology (198 lesions) and by follow up (25 lesions). Two doctors retrospectively reviewed all plain and dynamically enhanced MRI under unknown final results and analyzed the sensitivity of detection and accuracy of characteristic diagnosis. Results: In 132 lesions more than 3 cm, the sensitivity of detection on only plain MRI, plain plus dynamically enhanced MRI was above 97.7%. Although dynamically enhanced MRI improved accuracy of characteristic diagnosis (95.5%), there was no significant statistic difference from plain MRI (90.9%). In 91 lesions less than 3 cm, there was statistic difference of detecting sensitivity between plain (T 1WI+ T 2WI,92.3%) and dynamically enhanced MRI (arterial phase + portal venous phase, 98.9%, P 0.05 ). Also the detection of lesions in arterial phase (96.7%) was obviously higher than that in the portal venous phase ( 85.7% , P 0.01). The accuracy of characteristic diagnosis for plain combining dynamically enhanced MRI ( 91.2% ) was obviously higher than only plain MRI (75.8%, P 0.01). Conclusion: Dynamically enhanced MRI is an effective method for improving detection and characterization of focal liver lesions." @default.
