A DXA (dual energy X-ray absorptiometry) scan, is a special X-ray procedure that can be used to measure the bone mineral density, in order to assess your risk of breaking a bone. In general, if the density is low, or you lack calcium or vitamin D, then there’s a greater chance of a fracture.
MRI (Magnetic Resonance Imaging) is a safe way to produce images of the body in high detail. During an MRI scan a large, powerful magnet, radio waves and an advanced computer are used to take incredibly detailed images of the relevant part of your body. There are no known side effects of an MRI scan, and it is normally a pain-free procedure.
Ultrasound is a non-invasive scan used to diagnose and monitor conditions in many parts of the body. It can be used to determine the extent of injuries, as well as to guide injections and therapeutic procedures. Some men's and women's health tests are carried out using ultrasound including testicular, gynaecological and pregnancy scans. Ultrasound scans are safe, painless and have no known side effects.
An X-ray machine produces images of the inside of the body. It is effective in assessing bones and other dense structures within the body.
