title: A primer on medical imaging--Part two.
abstract: This month FDA Consumer offers the second of two articles on the wide array of radiological techniques that physicians can use to help them 'see' inside the body. The first article, in last month's issue, covered techniques that use X-rays, though often in ways far different from the traditional X-ray machine. Part two covers non-X-ray techniques, some of which work without potentially hazardous ionizing radiation.
