Learning objectives
MRM relies on the presence of well-established morphological features that help distinguish malignant from benign lesions.
In addition,
angiogenesis induced by cancer is demonstrated by dynamic contrast-enhanced MRI.
Compared with conventional mammography and breast ultrasonography for clinically overt and occult breast disease,
MRM offers higher sensitivity for the detection of multifocal cancer,
which is important in selecting patients appropriate for breast-conserving surgery.
These include preoperative staging before a planned breast-conserving surgery in patients with dense parenchyma to exclude multicentricity,
additional evaluation of dense breast tissue and scarring after breast-conserving therapy,
evaluation of breast implants,
and detection of the primary carcinoma in patients with axillary lymph node metastases
Unilateral multifocal cancer has a frequency of a least 30% and is seldom detected by clinical examination.
Filiations of these multiple cancers rather difficulty defined (multiple simultaneous cancers or cancers with plural different evolution).
It seems,
however,
that the presence of multifocal lesions implies a high probability of malignancy and poor prognosis.
The aim of this study was to assess the diagnostic performance of conventional mammography,
breast ultrasonography,
and dynamic contrast-enhanced MRM with regard to the detection of breast malignancy and recognition of a multifocal cancer,
in particular in a dense breast.
