The Newest CT: Faster than a Heartbeat
Date: June 23, 2014
New CT scanner at Johns Hopkins could positively affect coronary artery disease.
In one revolution around the body, the newly arrived 320-detector computed tomography (CT) scanner at The Johns Hopkins Hospital is poised to change the management and outcomes of coronary artery disease (CAD). The only other such scanner in the U.S. is at the National Institutes of Health. Johns Hopkins will be the first to use the new scanner for clinical purposes.
The fastest CT scanner available, it scans cardiac vessels and the heart in less time than it takes for a single heartbeat. The scanner is poised to replace invasive tests such as angiography for sorting patients having chest pain who need treatment (e.g., coronary angioplasty, a cardiac stent, bypass surgery) from those who don’t.
“Our goal,” says Joao Lima, director of cardiovascular imaging for Johns Hopkins, “is to increase certainty about which patients need an invasive procedure for opening an arterial blockage and to spare patients who do not from the risk of unnecessary diagnostic procedures.”
“Speed and accuracy of diagnosis are the bottom line,” says Lima, who sees CT as the ultimate device for assessing patients for CAD the world over. “We are learning more and more, which clinicians everywhere can use to make better assessments of coronary disease and administer the best care.”
