目的 比较3种3.0 T MRI扫描序列对腰椎小关节软骨成像的图像质量及特点。材料与方法 前瞻性纳入健康受试者30例，均接受L4/L5～L5/S1的3.0 T MRI的腰椎常规序列（T1WI及T2WI序列）、三维快速扰相梯度回波水激励序列（water excitation three-dimensional spoiled gradient echo sequence, 3D-WATSc）、基于T1加权的三维快速场回波（three-dimensional T1 fast field echo, 3D-T1-FFE）、基于质子密度加权的三维各向同性快速自旋回波（three-dimensional proton density weighted imaging volumetric isotropic turbo spin echo acquisition, 3D-PDWI-VISTA）序列扫描。对MRI图像进行成像效果的定...

Objective: To compare the image quality and imaging characteristics of three 3.0 T MRI sequences of lumbar facet joint cartilage.Materials and Methods: Thirty healthy subjects were studied with four chosen sequences using a 3.0 T MRI scanner. The sequences were T1WI/T2WI, water excitation three-dimensional spoiled gradient echo sequence(3D-WATSc), three-dimensional T1 fast field echo(3D-T1-FFE) and three-dimensional proton density weighted imaging volumetric isotropic turbo spin echo acquisition(3D-PDWI-VISTA).Two radiologists subjectively eval...
