Results
We evaluated; the lesion morphology and signal intensity on T1W,
T2W and STIR images and perfusion characteristics with parametric mapping and time intensity curves.
We also evaluated the spectroscopy findings of the proven malignant breast masses and the additional lesions that were diagnosed as possibly malignant based on MRI characteristics.
A total of 35 lesions were identified,
33 of them were malignant ( 2 patients had additional lesions,
confirmed on histopathology) and 2 were classified as benign based on morphology and contrast kinetics,
the lesions varied in size from 2.2 x 1.9 to 0.8 x 0.7 cms.
•The malignant lesions and the additional detected lesions that were classified as malignant showed spiculated or irregular outline and type II or Type III contrast kinetics.
•Only 18 lesions showed a tall choline peak on spectroscopy,
these lesions were all larger than or equal to 1.0 cubic centimeter in their dimensions.
•The lesions that were smaller than 1.0 cubic centimeter but not very small (9 in number) did show a small choline peak on spectroscopy.
•The lesions that were significantly smaller than 1.0 cubic centimeter did not show choline peak (6 in number),
neither did the 2 benign (small fibro adenomas) lesions.
