摘　　要：目的以子宫肌瘤为例研究人体组织结构(包括肿瘤)在MRI影像上的共同特征性,以得到"相同组织结构有相同的MR共性"的研究结果;反映在MR值上,希望得到有共同的、相对恒定的MR值区间范围。方法应用MicrosoftVisual C++6.0为本研究专门开发的专用MRI图像分析软件,对所有研究的子宫肌瘤在MRI T2原始序列图像的数据进行分析,研究在MR值上的变化规律。结果①在同一检查条件下,同一患者不同时期的子宫肌瘤影像中,MR值分布范围没有统计学差异(P>0.05);②在同一检查条件下,不同患者间的子宫肌瘤影像中,MR值分布范围没有统计学差异(P>0.05);③在同一检查条件下,子宫肌瘤HIFU治疗前后的MR值变化范围存在统计学差异(P<0.05)。结论①在同一MRI检查设备上,相同的检查条件下MRI影像中,相同人体组织结构有共同的MR值分布区间范围;②HIFU治疗能够改变原有组织结构在MRI图像上的特性。Objective To study the common imaging characters of the human tissues such as tumors in MRI based on hysteromyoma in hope of getting the results that the same tissue has the same MR characters and identifying the common, comparatively steady MR figs sectional area which can provide related references for the computer-based automatic recognition orgnization and basis for the question such as whether the same MR figs has the same hyperacoustic impedance characters. Methods We analysed all the images with hysteromyoma on MRI T2 and got the rules on MR figs change with the application of the MRI image analysing software which specially designed by Microsoft Visual C^＋＋ 6.0 for the research. Results （ 1 ） No significant difference was found in MR figs sectional area in the different periods of the same patient under the same MRI test condition. （2） No significant difference was found in MR figs sectional area in different patients under the same MRI test condition. （ 3 ） Significant difference was found in MR figs sectional area after the patient received the HIFU treatment under the same MRI test condition. Conclusion （ 1 ） Human tissues have some common MRI imaging characters in the same MRI test equipment under the same MRI test condition. （2） Imaging characters of the human body tissues in MRI can be altered after HIFU treatment.
