The U.S. Preventative Services Task Force (USPSTF) has finalized new breast cancer screening guidelines for women ages 40 to 74.
The USPSTF is constantly scanning the medical literature to see if its recommendations should be updated, says USPSTF chair Wanda K. Nicholson, MD, MPH. Ultimately, it decided to drop the ...
Women over 40 should get breast cancer screenings every other year, according to the U.S. Preventive Services Task Force. But some doctors think scans should be annual.
The U.S. Preventive Services Task Force recommends that women over the age of 65 should get a DXA scan. [3] The age when men should be tested is uncertain, [3] but some sources recommend age 70. [4] At risk women should consider getting a scan when their risk is equal to that of a normal 65-year-old woman.
The United States Preventive Services Task Force recommends osteoporosis screening for women with increased risk over 65 and states there is insufficient evidence to support screening men. [21] The main purpose of screening is to prevent fractures. Of note, USPSTF screening guidelines are for osteoporosis, not specifically osteopenia.
The improvement to DXA with DXL is that, for each pixel scanned by DXA, the exact thickness of the measured object is also measured using lasers. The DXL results allow for a more accurate estimation of bone density by using three separate inputs (low and high x-ray energies plus thickness) rather than two for each pixel in the measuring region.
