Abstract
Aim: To evaluate the experience with breast tumors imaging on three-Tesla MRI using dedicated eighteen-channel breast coil and multiparametric assessment. Method: The results of the 3T MRI were compared with those obtained by the histopathological evaluation of the resected breasts.
The mean age of women was 51.8 y with the range 25 to 67 y The imaging protocol included the morphological imaging, diffusion imaging, assessment of the dynamic enhancement of the tissue including pharmacodynamic analysis and the assessment of the choline content within the spectrum of the single-voxel MR spectroscopy. Results: The sensitivity of 100% (18/18), specificity of 87.5% (7/8) was reached in detection of the malignant tumor.
The highest particular sensitivity and specificity showed restriction of diffusion 88.9% (16/18) a 87.5% (7/8) followed by the spectroscopy - sensitivity 72.2% (13/18), specificity 87.5% (7/8). In the detection of the axillary lymph nodes metastases, the sensitivity both with specificity reached 83.3%.
Conclusion: The multiparametric evaluation of the breast 3T magnetic resonance is highly sensitive and relative highly specific method of the breast carcinoma detection, the sensitivity and specificity in the evaluation of axillary lymph node sis also sufficient.
