Abstract:
Objective To discuss magnetic resonance fat suppression technique,such as Chemical Shift Selective and Short TI Inversion Recovery Sequence,and its clinical value.Methods 73 cases undergoing MRI fat suppression during March 2008 to July 2008 were adopted as the subjects,with such site examined respectively as the skull,basalis,nasopharynx,neck,bones and joints as well as abdominal pelvis.Comparative study of image quality was performed to determine the di-agnostic value of MRI fat suppression technique.Results Of the all cases,7 ones suffered from skull lesions,6 ones from eye diseases,11 ones from abdominal pelvic diseases,4 ones from liver diseases,4 ones from pancreas disorders,and 8 ones from pelvic diseases.Meanwhile,of 10 cases of basalis diseases,there were 8 ones of nasopharyngeal carcinoma and 2 ones of oropharynx disorder.Of 16 cervical disorders,there were 6 ones of neurogenic tumor,3 ones of leucoma,5 ones of metastatic tumor and 2 ones of lipoma.Of 15 cases of vertebral disorders and osteoarthropathia,there were 8 ones of bone contusion,3 ones of metastatic tumor,3 ones of angeioma and 1 case of lipoma.Fat suppression technique,with the lesion edge outlined clearly and the lesions containing adipose tissue identified,provided more information than regular MRI.Conclusion The fat-suppression technique can significantly improve image quality,enhance disease diagnosis rate,and thus is an important technology in MRI examination.
