A QTscan is performed, one breast at a time (each breast takes on average 15 minutes), with the patient laying in a prone position on the examination table with the breast suspended in a warm water bath inside the scan tank.

The QTI scan is contraindicated for patients with certain medical conditions (e.g., open wounds, pregnancy, lactation, sensitivities to disinfectants or adhesives, or magnetic implants such as pacemakers) and for those outside the supported range of up to 181 kg (400 lbs) and breast cup sizes approximately A through DDD.
