CT Scanners: April 11, 2012

It’s said ‘knowledge is power’. Nowadays doctors are getting information in minutes, thanks to advanced imaging.

“From x-rays to MRI. We have ultrasound, CAT scan, nuclear medicine, interventional radiology. So it’s a really a broad field,” says Dr. John Rodriguez, medical director of outpatient imaging for Lee Memorial Health System.

In the spectrum of specialty equipment, there’s a rising star.

“CT imaging, that’s the trend,” says Dr. Rodriguez,

CT scanners are taking some of the load from x-rays and more and more often becoming the go-to diagnostic tool.

“We use that to diagnose things everything from broken bones to cancer to hemorrhages in the brain,” says Dr. Cory Duffek, a radiologist on the medical staff of Lee Memorial Health System.

Producing images with intricate detail.

“A CT scanner uses x-rays to make an image of a patient non-invasively. We take images of the patient over 360 degrees and then mathematically reconstruct that into an image or a slice. We see bone, muscle, tissue, air, we can image from head to toe,” says Dr. Duffek.

New CT scanners give off less radiation.

“What we’re able to do now is reduce the radiation dose to the patient by about 10-15% and sometimes up to 40% for certain scans and still get the same image quality,” says Dr. Duffek.

Scans take less than a minute. Lee Memorial Health System is equipping itself with a fleet of new scanners, including the area’s first 128-slice scanner.

“One area that it really plays a big role in is a work up of acute stroke. We are able to not only identify whether is ischemic or hemorrhagic stroke, we can identify which blood vessel is causing the stroke,” says Dr. Duffek.

It’s giving doctors powerful tools and scanning the horizon of health care.
