QTbreasthealth and QT Ultrasound Claims References
*QTscan is FDA-cleared
QT Ultrasound has received FDA clearance for its breast imaging system. The QTscan is not intended as a replacement for screening mammography.
The QTscan should not be used by or for the following:
- Those advised by their physician to avoid immersing their breast in water
- Those with open wounds, sores or any condition which causes visible skin scaling and shedding on the breasts
- Pregnant or lactating women
- Those experiencing ANY nipple discharge
- Patients weighing more than 400 lbs.
- Those with a breast cup size greater than DDD or whose breast does not fit comfortably through the opening in the QTscanner table insert rings
- Patients with magnetic implants, such as pacemakers, temporary breast implants or tissue expanders with magnetic ports, pain pumps or stimulators, or other devices or implants with magnetic properties
- Those with allergies to chlorine, alcohol wipes, or medical grade adhesive tape.
