呼吸训练对磁共振胰胆管造影图像质量的影响

Influence of Respiratory Training on MRCP Image Quality

目的探讨呼吸训练对磁共振胰胆管造影(MRCP)图像质量的影响。方法将60例行MRCP检查的患者随机分为两组,其中训练组(30例)在检查前进行呼吸训练,未训练组(30例)在检查前不进行呼吸训练。对两组图像的质量进行评级,分为差(1分)、中(2分)、良(3分)和优(4分)4个等级,再采用秩和检验比较两组图像的质量。结果训练组图像的质量明显优于未训练组图像的质量,两组差异有统计学意义(P<0.05)。结论呼吸运动对MRCP的图像质量有很大影响,检查前嘱患者进行呼吸训练能够提高MRCP图像的质量。

Objective To investigate the influence of respiratory training on MRCP （Magnetic Resonance Cholangiopancreatography） image quality.Methods Altogether 60 patients who underwent MRCP examinations were randomly and evenly divided into two groups： training group （30 cases） and un-training group （30 cases）. Pre-examination breathing training was performed in training group. While, no such training was performed in un-training group. Then, the image quality in both groups was assessed into 4 grades ranging from bad （1 score）, fair （2 score）, good （3 score） and excellent （4 score）. The rank sum test was used to analyze the assessment results.Results The image of training group demonstrated high quality than those of un-training group. And statistically significant differences existed between the two groups （P〈0.05）.Conclusion Respiratory motion could cause great influence on image quality. Pre-examination respiratory training improved the quality of MRCP images.
