Abstract

Following initial mammography imaging (craniocaudal and mediolateral oblique views) an abnormality may be identified which requires further analysis. Clear mammographic presentation of a lesion or microcalcification is crucial for accurate assessment. Identifiable masses such as cysts, fibroadenomas and larger carcinomas usually proceed to an ultrasound examination without the requirement for further mammographic views [1]. Many masses demonstrated as microcalcification or an asymmetrical density, may not be instantly identifiable on the initial mammograms, and will need further assessment with specialised mammography [2]. The location of the abnormality in the breast can be confirmed by obtaining a lateral view, particularly in the case of microcalcification. This enables the microcalcification to be characterised [3].
