APPLICATION OF 64-SLICE SPIRAL CT PERFUSION IMAGING IN THE DIAGNOSIS OF BREAST DISEASES

[Objective]To study and evaluate multi-slice spiral CT perfusion imaging in the diagnosis of breast diseases the effect and value.[Methods]61 patients through clinical examination or mammography of women with suspected breast disease patients with 64-slice spiral CT perfusion imaging. The pathology types were divided into three groups:hyperplasia group(n = 14),fibroadenoma group(n = 19)and breast cancer group(n = 20),and contralateral breast in all patients as the normal group(n = 61). After perfusion sequence body perfusion body scan and perfusion Perfusion 3 software processing,the hemodynamic parameters were calculated,including area blood flow(BF),mean transit time(MTT),blood volume(BV)and permeability surface(PS),and we analyzed the significant difference among the different groups.[Results]Compared with the breast cancer patients,there was significant difference among BF,BV and PS(P﹤0.05),and there was no significant difference in MTT(P﹥0.05);Compared with the normal mammary gland and fiber adenomas and hyperplasia disease group,there was significant difference among the BF and BV(P﹤0.05),there was no significant different in MTT and PS(P﹥0.05);Compared the breast cancer group with fibroadenomas group,there was significant difference in BF and PS(P﹤0.05),and there was no significant difference between BV and MTT(P﹥0.05);Compared the breast cancer group with the glands group,there was significant difference in the BF,BV,and PS(P﹤0.05),and there was no significant difference in MTT(P﹥0.05);Compared illness group c with fibroadenomas group,there was no significant difference in BF,BV,MTT,and PS(P﹥0.05). Normal group and the breast cancer group SHOWED hypoperfusion,high perfusion,fiber adenoma,and hyperplasia group showed a higher perfusion.[Conclusion]64-slice spiral CT imaging as an advanced technology,its hemodynamics and perfusion imaging could accurate diagnosed the breast disease.
