Learning objectives
The exhibit will discuss the ……
•Known signs in MRM and illustrate them with examples so that,
in the future,
this information can be applied in the practical interpretation of MR mammograms.
•Recent advances in MRM: role of diffusion,
perfusion and spectroscopy imaging.
Background
•MR mammography (MRM) is new avenue in the diagnosis of breast cancer.
With the advances in the temporal resolution MRM can accurately detect breast cancers larger than 3 millimetres.
•The problem in recent years has been an international debate concerning methods,
techniques,
and the interpretation of the myriad images.
•Recent advances in MRM: role of diffusion,
perfusion and spectroscopy imaging.
Imaging findings OR Procedure details
•It is important for the general radiologist to be familiar with indications and contraindications,
equipment and patient positioning,
imaging basics,
the ACR BI-RADS® lexicon,
common artifacts,
common lesions,
post-treatment evaluation,
and silicone implant evaluation.
•With a focus on the basic imaging principles of breast MRI rather than on mathematical equations,
this exhibit will show a practical approach to imaging protocols that helps radiologists increase their diagnostic effectiveness.
MRI protocol was standardized in all cases.
Diagnostic enhanced breast MRI was performed at 1.5T and 3.0T clinical...
Conclusion
It is important for the general radiologist to be familiar with indications and contraindications,

With a focus on the basic imaging principles of breast MRI rather than on mathematical equations,
this exhibit shows a practical approach to imaging protocols that helps radiologists increase their diagnostic effectiveness.
•High sensitivity but low specificity,
has been used like a mantra to characterize MRM.
But results in recent decades...
