Radiology is the medical specialty directing medical imaging technologies to diagnose and sometimes treat diseases. Originally it was the aspect of medical science dealing with the medical use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging.

CT and fiber-coated surgical microcoils help locate small lung nodules

A new technique combining computed tomography (CT) with fiber-coated surgical microcoils allows physicians to successfully locate and remove small lung nodules without the need for a more invasive procedure, according to a new study published in the February issue of Radiology.

New imaging technique catches arthritis early

You come into a doctor's office with severe knee pain. The physician orders an MRI, which reveals substantial loss of cartilage - osteoarthritis, that is - in your knee joint. At this point, not much can be done beyond gulping down palliatives and trying to keep your weight off the joint. But the damage may have started building as much as 20 years earlier, possibly due to a traumatic injury to the affected joint.
