Influences of Tumor Volume and FWHM of the Water Peak and T₂* Value of Water on the Detection Rate of the Choline Peaks in Proton MR Spectroscopy of Breast Cancer at 3.0 T-MRI

In proton magnetic resonance (MR) spectroscopy (1H-MRS) of the breast cancer, choline peak could be detected. The purpose this study was to evaluate influences tumor volume, full width at half maximum (FWHM) water (FWHM), and T2* value (T2* value) on detection rate peaks 3.0 T-MRI. We measured FWHM in 109 cases, we evaluated effect volume peaks. 1H-MRS cancer T-MRI, improved as larger. As a shimming environment when acquiring is preferably 57.4 Hz or less should 11 ms more, has great influence
