Methods and Materials
In 30 patients with histopathologically proven primary breast cancer,
we performed breast MRI using dedicated breast coil using FSET1W,
FSET2W,
STIR and Multiphase dynamic contrast enhanced sequence to look for additional lesions in the same as well as the contralateral breast.
In additional we performed MR spectroscopy of the known malignant breast mass.
MRS Protocol: The breast spectroscopy sequence is a spin-echo sequence with regional saturation bands for outer volume suppression.
•In our series we performed Single Voxel Spectroscopy (SVS).
•In Single-Voxel Spectroscopy (SVS),
the placement of the (cuboid volume) voxel,
on the region of interest,
is of critical importance,
to obtain robust chemical (metabolite) signals.
•MR spectroscopy should be performed with the same coil that is used for MR imaging so that the imaging and spectroscopy data are directly comparable.
We performed MR Spectroscopy after acquiring Dynamic Contrast Enhanced images as we based our decision of voxel placement after reviewing lesion morphology and contrast kinetics,
while the patient is still in the magnet
