What is diagnostic imaging?

Diagnostic imaging refers to technologies that doctors use to look inside your body for clues about a medical condition. A variety of machines and techniques can create pictures of the structures and activities inside your body. The technology your doctor uses will depend on your symptoms and the part of your body being examined. X-rays, CT scans, nuclear medicine scans, MRI scans and ultrasound are all types of diagnostic imaging. Many imaging tests are painless and easy. Some require you to stay still for a long time inside a machine, though. This can be uncomfortable. Certain tests involve radiation, but these are generally considered safe because the dosage is very low.

No diagnostic test confirms progeria. Doctors typically make a diagnosis based on signs and symptoms, such as failure to grow and hair loss, that typically aren't fully evident until your child is nearly 2. However, with the discovery of the genetic mutation that causes progeria, it's possible to use genetic testing for LMNA mutations at the first suspicion of progeria. The sooner you know your child has progeria, the sooner your doctor can recommend treatments that may help ease the signs and symptoms of the disorder.
