Noninvasive diagnostic techniques in cardiology.

Noninvasive cardiology has made notable progress in the last several years. A variety of sophisticated tests are now available to the clinician, providing both anatomic and physiologic information. The result has been an improvement of the level of diagnostic accuracy, which in a final analysis translates into better patient care. Newer tests such as cardiac CAT scan and nuclear magnetic resonance, using incredibly advanced technologies, continue to be investigated and almost certainly will play an important role in cardiovascular diagnosis in year to come.
