Special cases – cases with a unique diagnosis or pathognomonic ultrasound appearance:. The term density describes the degree of x-ray attenuation of breast tissue but not discrete mammographic findings.

The breasts are almost entirely fatty. In other projects Wikimedia Commons. The accuracy statistics are generally calculated once a year and they are important in quality assurance, that is they tell the radiologist whether they are doing a good job or not.

Compare to previous studies. BI-RADS mammogram classifications are not intended as a diagnostic toolbut only as a means of standardizing communications and helping to identify situations where follow-up clasficacion required, and the most appropriate type of follow-up.

Calcifications The distribution should be measured by approximation of its greatest linear dimension. Posterior features represent the attenuation characteristics of a mass with respect to its acoustic transmission, also of additional value. Only at the moment when a radiologist is finishing a report and needs to assign the findings into a category. The palpable mass is a simple cyst.

Asymmetries appear similar to other discrete areas of fibroglandulair tissue except clasiricacion they are unitaleral, clasificacino no mirror-image correlate in the opposite breast.
