ARA’s Latest CT Scanners Have Lower Radiation

Modern diagnostic imaging has brought vast improvements in diagnosis and treatment, sparing us from invasive surgeries and finding disease in earlier and more curable stages. Some radiological modalities do not use ionizing radiation, or x-rays. For instance, magnetic resonance imaging (MRI) uses magnetism to create images and ultrasound uses sound waves. Sometimes, the best diagnostic exam for you is a CT (computed tomography) scan, which uses x-rays. CT scans impart a small amount of radiation in the process of creating sophisticated, detailed images used for diagnosis. Click Here to learn about the patient benefits of CT scanners.

ARA’s current class of CT scanners is an advanced group with a new technology that allows for up to 60% radiation dose reduction while producing outstanding images that are better than older machines can produce. It’s an important step forward for patients needing CT scans, especially if you need multiple scans for a chronic disease.

This impressive reduction in radiation is accompanied by highly detailed scan quality, enabling exceptional imaging of the inside of your body. The new CT scanners are also faster, helping to reduce the need for you to hold your breath, which is especially helpful for children and the elderly. Patient-friendly design makes the new CTs more comfortable and automated technology helps CT technologists spend more time with you and less time adjusting the scanner.

At ARA, we hold patient radiation safety to the highest standards and that is why our CT dosages are below the recommended benchmark. We devote a significant part of our practice to finding ways to reduce your radiation dose while getting the finest quality images that you and your physician need.
