MBI (shown right) and 3D (shown left) are both superior to standard 2D mammography but that’s where the similarity ends. 3D detects slightly more cancers than standard 2D mammography, but MBI is much better in detecting breast cancer in women with dense breast tissue.
MBI and 3D mammograms are completely different technologies
They show different things
The current protocol is to use them together
New laws provide notice to women with dense breasts
MBI is a new, experimental technology (FALSE)
MBI was developed by Mayo Clinic and cleared for safety by the U.S. Food and Drug Administration in 1999. In 2008, a landmark study concluded that MBI was more effective than a mammogram for women with dense breasts. In 2015 and 2017, two major studies confirmed the effectiveness of MBI in combination with mammography.
The newest generation of MBI imaging is quite different from systems available even five years ago (the MBI unit at Mayo Clinic Health System in La Crosse is the latest technology as of October 2017). Testing and innovation will continue, but MBI is a mature, safe technology.
MBI is expensive (FALSE)
Cost is in the same range as a 3D mammogram.
MBI uses a high dose of radiation (FALSE)
Over time, MBI tracer dosage has been reduced considerably and is now comparable to a mammogram. It is also less than natural radiation levels absorbed annually from the environment (called background radiation).
MBI and 3D mammography are both in the low-dose range, when compared to most other radiology examinations.
