Color flow imaging is where the color doppler (sound wave) is applied during the ultrasound portion, with increased vascularity of the area in question. The mammogram was given a birads 0,indeterminate, Incomplete needs additional imaging, more than likely because your mammogram needed additional imaging (Ultrasound), therefore was read as a separate exam. The ultrasound portion was given the birads 4/5 as a final result code. Your PCP (Doctor) should send you to a surgeon, please be sure and go see one soon.
The birads codes are as follows:
Birads 0- Incomplete needs additional imaging
Birads 3-Probably benign(usually 6 mos follow up)
Birads 4-Suspicious ( A,or B,or C )
Birads 5-Highly suggestive of malignancy
Birads 6-Biopsy proven malignancy
I have had several biopsies and breast cancer twice. I am very familiar with the mammography birads assessment not an expert but I do understand it fully.
