As with MBI, it exposes the whole body to radiation, so it’s unlikely to be a test that could be used every year for breast cancer screening.
One potential drawback is that it exposes the whole body to radiation, so it’s unlikely this test would be used for screening every year.
Positron Emission Mammography (PEM) is a newer imaging test of the breast.

This test is approved by the FDA to help classify tumors found on mammograms.
But at this time there hasn’t been enough clinical testing to use it for breast cancer screening.
The technique does not use radiation and does not require breast compression.
Studies going on now are looking at combining optical imaging with other tests like MRI, ultrasound, or 3D mammography to help look for breast cancer.
Molecular breast imaging (MBI) is a newer nuclear medicine imaging test for the breast.
