> Breast MRI had a cancer detection rate (CDR) of 10.8 per 1,000 exams compared to mammography’s CDR of 8.2 per 1,000 examinations. However, breast MRI had a biopsy rate of 10.1%, double that of mammography’s 4% rate. [emphasis added]
What's going on with the biopsy rate? Is it something as simple/nefarious as recouping the cost of the equipment?
- seren 7y agoI have not read the article but I believe that usually routine exams are done with X Ray, because it is quicker and cheaper. However if something is a bit worrying, doctor may ask for a different type of exam, MRI or Ultrasound, to have some confirmation. But since this is rarer people who have MRI are already people at risk, so it makes sense to have a higher rate of biopsy in the end.
