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 T

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.
