The value of magnetic resonance T1 perfusion imaging in differentiating benign and malignant breast tumors / 中国基层医药

ABSTRACT

Objective To investigate the value of magnetic resonance perfusion imaging in differentiating benign and malignant breast tumors.Methods The subjects were confirmed by magnetic resonance perfusion imaging in the diagnosis of breast lesions in 68 patients,and histopathologic examination of the control and analysis of its results.Results After perfusion weighted magnetic resonance imaging line parallel operation therapy,68 cases breast lesions in patients with pathologically confirmed,32 cases of benign tumor and malignant tumor in 36 cases;further observations on lesions of the morphology and dynamic enhanced performance,rendering their time-signal intensity curve,benign tumor type (inflow),type Ⅱ (platform) and type Ⅲ (clearance type) were 78.1％ (25/32),18.7％ (6/32),3.2％ ( 1/32),malignant tumor were 2.8％ ( 1/36 ),33.3％ ( 12/36 ),63.9％ ( 23/36 ),two groups had significant difference (P ＜ 0.05).Conclusion Mr T1 perfusion imaging for differentiating benign and malignant breast tumors have high application value,and has the advantages of simple operation,noninvasive advantages,worthy of clinical application.
