Combined apparent diffusion coefficient value (ADC) and 1H magnetic resonance spectroscopy (MRS) in breast lesions: Benefits and limitations
ConclusionA great advantage of ADC value is the significant difference between benign and malignant lesions, because of this it plays an important role in characterization of breast lesions. MRS is the only in vivo technique which can detect tissue metabolites. In our study combined MRS with ADC value increased sensitivity in detecting lesions, while the specificity remained at lower level than that of the ADC value alone.
