Rapid CT programs may lead to faster diagnoses, but some say they may not be appropriate for all trauma patients and could unnecessarily increase radiation risk.
CT-Related Cancer Risk Among Children Can Be Lowered
Children’s risk from radiation exposure from CT scans drops significantly when dose from the highest-dose exams is lowered and unnecessary exams eliminated.
Contrast-Enhanced CT Significantly Increased Radiation Dose
Contrast media with CT significantly increased radiation dose, so number and timing of contrast-enhanced scans should be optimized when setting protocols.
Virtual Colonoscopy Screening Can Be Later for Women
Experts may consider new guidelines for virtual colonoscopy, or CT colonography, screening after study shows women can be screened later than men.
Early Colonoscopy Beneficial for Patients with CT-diagnosed Acute Diverticulitis
Patients with acute diverticulitis diagnosed by contrast-enhanced CT may benefit from early colonoscopies for colon cancer screening.
Chest Tomosynthesis Shows Promise for Early Cancer Detection
Digital chest tomosynthesis used as a screening tool for lung cancer shows comparable rates of detection to low-dose CT.
Low-Dose CT Detects More Lung Cancers, Lowers Mortality
Study confirms earlier findings that low-dose CT detects more lung cancer than chest X-rays and lowers mortality from lung cancer.
Small Increased Cancer Risk for Children Who Have CT Scans
CT scans performed on children and adolescents may contribute to a slightly elevated risk cancer over the following 10 years.
Podcast: A Conversation about Lowering Radiation Dose
Diagnostic Imaging spoke with Dr. Johnsey Leef III, a radiologist with Charleston Area Medical Center in Charleston, WV, about how the industry is responding to the call for lower dose imaging and what his department is doing to address the issue.
