When working up microcalcifications by all means jump right in with mag views.
When you work up a mass or symmetry, pause and consider what it is you wish to see, exactly.
In this case a very small lesion quite deep and the tech is likely going to have a tough time locating the precise spot in quite a generous breast. If the tech is lucky, she will image it first time. If not, repeat views and a struggle may ensue and the patient becomes progressively more concerned by the process.
In cases like this its often the quickest and simplest strategy to just repeat the CC ( or do an ML ) view. Even a very subtle degree of rotation or obliquity, a couple of degrees, gives you separation of the tissue and definition of the lesion.
As a general rule (not always true ) when you want to evaluate an asymmetry do rolled CC and ML views. It gives you so much extra information and an almost 3 D picture of gland on fat. Small lesions like this one can be tough to find. Do the CC view first and if you are still puzzled you can add the mag views. The tech will them also know where the lesion is.
In this case, the extra CC view would have given me the answer right off the bat. Birads II follow up in one year.
