Breast lesions, may be identified on MRI that are not shown on mammography
or ultrasound owing to the high sensitivity and relatively poor specificity
of contrast enhanced MRI. Techniques for diagnostic biopsy of such lesions
are not widely available. A method is described that uses standard mammogr
aphic localization methods to place an MR compatible cerebral coil at the s
ite of the suspect lesion. Confirmatory MRI can then be obtained before the
lesion is surgically removed using a mammographic hook wire. This method i
s described and illustrated in detail for one case, and in summary for thre
e further cases, to show the potential flexibility of application. The meth
od is commended because it is simple and cheap, uses standard breast proced
ures and can be undertaken outside the MRI suite. The procedure will make f
ull use of breast MRI possible to those who do not have dedicated localizat
ion equipment.
