Diagnostic Value of Breast Proton Magnetic Resonance Spectroscopy at 1.5T in Different Histopathological Types

Figure 3

MRI and MRS measurement in a patient with false-positive benign lesion. This patient showed dense glandular tissues on the sagittal precontrast image and mild enhancement on the enhanced MR image. The spectroscopic voxel size was 2 × 2 × 2 cm³. 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 yields a measurement of [tCho] = 0.66 ± 0.10 mmol/kg, the estimated model fit is shown above the full spectrum, and the residue is shown underneath.
