Abstract:
Objective To explore the application value of non coherent diffusion weighted imaging(IVIM) model in magnetic resonance body element for differentiating benign and malignant breast cancer.Methods Compar-ison of dynamic enhanced magnetic resonance (DCE -MRI)was conducted in 60 patients with breast occupying lesions,all patients were not treated with biopsy or needle biopsy before MRI scan.The lesions were obtained by oper-ation or biopsy after MRI scan,confirmed by pathology,39 benign lesions(benign group),28 malignant lesions(malig-nant group).IVIM-DWI parameters of two lesions group(D value,D* value and F value)were compared,analyzed IVIMDWI model parameters(D value,D* value and F value)diagnostic efficiency of diagnosis of benign and malig-nant breast lesions.Results Compared with two lesions groups,in the IVIM DWI model parameters,the D value of the malignant group was (0.95 ±0.19)×10 -3 s/mm2 ,which was significantly lower than (1.33 ±0.25)×10 -3 s/mm2 of the benign group (t =3.89,P <0.05),the F value of the malignant group was (8.97 ±2.01)%,which was significantly higher than (7.01 ±2.13)% of the benign group (t =3.93,P <0.05),there was no significant differ-ence in D* values between the two groups (P >0.05).IVIM DWI model in differential diagnosis of breast lesions had high diagnostic efficiency.Conclusion IVIMDWI model in the diagnosis of benign and malignant breast cancer is highly effective,and it has high clinical value.
