New Low-Dose Radiation CT Scanner at Texas Health Southwest Cuts Exposure Nearly in Half|
FORT WORTH, Texas — Texas Health Harris Methodist Hospital Southwest Fort Worth is the first hospital in Tarrant County to offer the next generation of diagnostic imaging technology that cuts patients’ radiation exposure nearly in half.
The 64-slice computed tomography scanner with adaptive statistical iterative reconstruction (ASIR) delivers high-speed, high-quality images with up to 40 percent less radiation, representing an important advancement in CT scan diagnostics.
To patients, this could mean a reduced risk of developing cancer from routine CT scans. A study published in the Archives of Internal Medicine in December found that radiation from CT scans done in 2007 will cause an estimated 29,000 cancers and kill nearly 15,000 Americans. The researchers estimated there will be an extra 2,000 excess breast cancers just from CT scans performed that year.
“This technology enables us to drastically reduce radiation levels and administer just the dose required to achieve quality images,” said Dr. David Robinson, medical director of radiology at Texas Health Southwest. “This is especially important for patients who may need multiple imaging tests, such as cancer patients, and for women of child-bearing age.”
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 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 Brett McClung, president of Texas Health Southwest. “I am proud that Texas Health Southwest is the first hospital in Tarrant County to offer this important advancement to our patients.”
