A BI-RADS classification of 4 or 5 warrants biopsy to further evaluate the offending lesion. [3] Some experts believe that the single BI-RADS 4 classification does not adequately communicate the risk of cancer to doctors and recommend a subclassification scheme: [4] 4A: low suspicion of malignancy, about > 2% to ≤ 10% likelihood of malignancy
BI-RADS 3 indicates probably benign. [53] BI-RADS 4 indicates suspicious for malignancy. BI-RADS 5 indicates highly suggestive of malignancy. BI-RADS 6 is for biopsy-proven breast cancer. [54] BI-RADS 3, 4 and 5 assessments on screening mammograms require further investigation with a second "diagnostic" study. The latter is a more detailed ...

These tools, while not officially endorsed by the ACR, are becoming more popular among radiologists for their ability to reduce variability and improve diagnostic efficiency. Examples include PI-RADS v. 2.1 calculators available on independent online platforms, [12] which helps in systematically applying the PI-RADS scoring system. These tools ...
Another example is NM data, where an NM image, by definition, is a multi-dimensional multi-frame image. In these cases, three- or four-dimensional data can be encapsulated in a single DICOM object. Pixel data can be compressed using a variety of standards, including JPEG , lossless JPEG , JPEG 2000 , and run-length encoding (RLE) .
