[Comparison of full-field digital mammography and magnetic resonance imaging for breast disease diagnosis].

OBJECTIVE: To compare the effectiveness of full-field digital mammography (FFDM) and magnetic resonance imaging (MRI) in the detection and diagnosis of breast diseases.

METHODS: Forty-one patients with 47 breast lesions (20 malignant and 27 benign lesions) underwent preoperative FFDM and MRI, using the pulse sequences including T1WI, T2WI, T2WI/SPIR diffusion-weighted imaging (DWl), and 3D dynamic contrast-enhanced MRI.

RESULTS: The imaging and pathological findings were compared, and the detection rates of the lesions by FFDM and MRI were 97.87% (46/47) and 74.46% (35/47), respectively (P<0.01). The sensitivity of FFDM and MRI was 70.00% (14/20) and 80.00% (16/20) (P>0.05), with specificity of 62.96%(17/27) and 88.89%(24/27) (P<0.05), respectively.

CONCLUSION: MRI is superior to FFDM in the detection and diagnosis of breast diseases.
