Diagnostic Value of Breast Proton Magnetic Resonance Spectroscopy at 1.5T in Different Histopathological Types
Figure 2
MRI and MRS measurement in a patient with mixed invasive ductal and lobular carcinoma. The equivalent 1-dimensional tumor size was 2.8 cm, and the spectroscopic voxel (size 2 × 2 × 2 cm3) was superimposed on the hypointense lesion in the precontrast sagittal image. The elevated tCho peak at 3.2 ppm is clearly visible in the water-fat suppressed spectrum. The Gaussian model fitting of the tCho peak produces a measurement of [tCho] = 8.51 ± 0.98 mmol/kg, the estimated model fit is shown above the full spectrum, and the residue is shown underneath. Creatine (Cr) peak at 3.02 ppm and taurine (Tau) peak at 3.45 ppm are also observed.
