Texas Health Plano is First Hospital in Texas to Offer Next-Generation CT Technology

PLANO, Texas — Texas Health Presbyterian Hospital Plano is the first hospital in Texas and one of only four in the world to offer patients the next generation of imaging technology.

The LightSpeed® VCT XTe 64-slice computed tomography scanner with Adaptive Statistical Iterative Reconstruction (ASIR) delivers high-speed, high-quality images with significantly less radiation, representing an important advancement in CT scan diagnostics. For patients, this means exposure to radiation is slashed by 30 to 40 percent for routine scans and up to 60 percent in some patients. For cardiac scans, radiation dosage can be reduced up to 83 percent.

With earlier-generation CT technology, radiologists could deliver lower doses of radiation, but reducing the dosage too much would result in obscuring the image. ASIR is a new advanced image reconstruction technique that makes it possible to dramatically reduce radiation without compromising the quality of the image.

“This technology enables us to drastically reduce radiation levels and administer just the dose required to achieve quality images,” said Mike Putman, RT (R)CRA, Director of Radiology and Medical Imaging at Texas Health Plano. “This is especially beneficial for children and young adults whose cells divide more rapidly, making them more susceptible to harm from radiation exposures.”

Dr. Ted Wen, pediatric radiologist and co-chair of radiology at Texas Health Plano, said it is important to understand the cumulative effects of radiation over one’s lifetime.

“Since we are all exposed to low level radiation every day from the earth, sun, and other sources, we strive to reduce medical radiation levels as much as possible,” Wen said. “As a radiologist, I live by the cardinal rule that each patient should receive “as low as reasonably acceptable” medical radiation. I can be passionate about the ASIR technology because we can now reduce radiation levels significantly and still achieve high quality CT images to help with the treatment and diagnosis of patients.”

Limiting radiation exposure is particularly important for patients who may need multiple imaging tests, such as cancer patients, Wen said. It’s also critical for pediatric patients and women of child-bearing age.

For heart patients, traditional CT scans required X-rays to be activated for several seconds in order to capture complete images of the heart muscle and surrounding tissue. ASIR technology reduces the actual time of the scan, capturing “snapshots” of the heartbeat so the total “on” time for X-rays is cut to less than a second, reducing radiation exposure by up to 83 percent.

“This represents a significant step forward in diagnostic technology that enhances our ability to fulfill our mission of improving the health of the people in the communities we serve,” said Jeffrey Canose, M.D., president of Texas Health Plano. “I am so pleased that Texas Health Plano is the first hospital in Texas to offer this important advancement to our patients.”
