Suspect breast lesions: findings at dynamic gadolinium-enhanced MR imaging correlated with mammographic and pathologic features.

摘要: PURPOSE: To prospectively correlate dynamic contrast enhancement at magnetic resonance (MR) imaging with mammographic and pathologic features of suspect breast lesions. MATERIALS AND METHODS: Forty-nine patients 51 lesions underwent gadolinium-enhanced spoiled gradient-recalled echo (SPGR) MR 1.5 T, as well excisional biopsy or cyst aspiration. RESULTS: Twenty-two 22 (100%) invasive carcinomas 8 mm more in diameter, including three (12%) not evident on dense mammograms, enhanced 2.0 times the unenhanced intensity. One predominantly ductal situ 10 26 (38%) benign times. Time-intensity curves were statistically significantly different among enhancing carcinomas, fibroadenomas, other showed no significant correlations size, nodal status, hormone receptor status carcinomas. CONCLUSION: had high sens...
