Pediatric- Dose CT Scans

Pediatric- Dose CT Scans

Years of research told doctors what many already suspected: that one-size-fit all radiography can be bad for children. "The pediatric populations we know from scientific studies are most susceptible to radiation and radiation-induced cancers. They're growing and they're developing and that makes it more susceptible," says Dr. Cory Duffek, neuroradiologist with Lee Memorial Health System. It's estimated that reducing the number of unnecessary and high dose CT scans given to kids could cut their lifetime risk of associated cancers by as much as 62%. "So over the last several years there's been a big push to use what we call a 'pediatric dose' for pediatric scanning," says Dr. Duffek. CT scans use X-ray to give doctors cross-sectional images of a patient's body. In children, they are most frequently to evaluate an injury. Now technology is making it easier for doctors to get what they need and still play it safe. "We're looking at one of our new GE scanners - this is one of the new scanners it has the low dose techniques available to us," says Dr. Duffek. Each Lee Memorial Health System radiology facility is equipped with scanners that provide variable doses, based on patient and need. Today, even a standard CT scan is much lower than 20 years ago. The latest equipment includes child-size protocols built in. "With our new generation of scanners now it allows us to lower that dose approximately another 13 to 30% and still get the same image quality that we were seeing," says Dr. Duffek. The immediate benefit of getting a timely CT scan makes it worthwhile. But lowering radiation exposure cuts down on risk and worry.

Noncontrast MRA (magnetic resonance angiogram) neck radiology search pattern

Noncontrast MRA (magnetic resonance angiogram) neck radiology search pattern

Another frequent study will encounter in neuroradiology is an MRA (magnetic resonance angiogram) of the neck. This test is frequently used to evaluate the arteries of the neck, including the carotid and vertebral arteries. MRA of the neck can be performed without contrast using a technique called time of flight imaging, which depends on signal from flowing blood to create the image. MRA of the neck can also be performed with contrast in certain situations, such as need to better evaluate the aortic arch and great vessel origins or need to imaging dynamically. MRA of the neck is primarily used to evaluate for vessel occlusion or narrowing, although vascular malformations may also be evaluated. It can also be used to follow up on vascular findings seen on other studies, such as doppler ultrasound of the carotids. The most common indication, however, is to evaluate for stroke, when it is combined with MRI and MRA of the brain. This video will walk you through a step-by-step approach to evaluating an MRA of the neck, including how to approach each vessel. I use an approach that moves from anterior to posterior and then right to left. While others may have a different strategy, the most important part is to have a strategy and stick to it. The level of this lecture is appropriate for medical students, junior residents, and trainees in other specialties who have an interest in neuroradiology or may see patients with atherosclerotic disease or stroke.

Dose Managemnt with ASiR - Customer Testimonial

Many patients have repeat CTs. Over years, they accrue large volume of CTs and that can lead to a lifetime of radiation dose. Advanced imaging protocols may enable physicians to remove image noise asscoiated with lower dose while obtaining a high quality diagnostic image. Learn how Childrens Mercy Hospital has employed ASiR in their imaging protocols.
