MRCP的3D FRFSE与2D SSFSE成像在3T MRI上的比较

The Comparison of MRCP between 3D FRFSE and 2D SSFSE at 3T

目的:比较3D-FRFSE,2D-SSFSE冠状薄层与2D-SSFSE旋转厚层在MRCP成像的优劣。方法:本研究纳入24名肝病患者,用GE signa exite 3.0T磁共振采集3D-FRFSE,2D-SSFSE冠状薄层及2D-SSFSE旋转厚层图像。利用GE ADW4.2图像后处理站对3D图像进行重建。将3D重建图像,2D薄层,2D厚层进行SNR及图像质量的比较。取P<0.05为有统计学意义。结果:3D图像SNR明显高于2D薄层和2D厚层,且3D MRCP图像质量比2D薄层MRCP和2D厚层MRCP好(P<0.05)。但2D薄层与2D厚层的图像质量没有明显差别。讨论:3D-FRFSE MRCP的信噪比明显高于2D厚层与2D薄层MRCP,并且3D的图像较2D能更好的显示病变。

Objective:This study aimed at the evaluation the technical SNR of and the visibility of the biliary tree and pancreatic duct on MRCP image obtained with a 3D FRFSE in comparison with 2D conventional SSFSE thin-section and thick-slab sequences.Materials and Methods:Twenty-four consecutive patients(14 men and 10 women,aged 35-65 years)were recruited.The images of 3D FRFSE,2D conventional SSFSE and 2D rotation SSFSE were acquired using GE signa-exite 3.0T MR.The SNR of reconstituted 3D FRFSE from GE ADW4.2-wor...
