GE’s ASIR cuts CT dose
A type of iterative reconstruction may reduce patient radiation dose from CT scans up to 65%, according to a study published in the September issue of the American Journal of Roentgenology.
GE’s ASIR cuts CT dose
A type of iterative reconstruction may reduce patient radiation dose from CT scans up to 65%, according to a study published in the September issue of the American Journal of Roentgenology. The technique, called adaptive statistical iterative reconstruction (ASIR) by its developer, GE Healthcare, reduces noise in the image, allowing a downward adjustment in radiation dose to obtain standard diagnostic quality images. Researchers at the Mayo Clinic Arizona in Scottsdale found nearly identical image quality using the reduced dose CT method with ASIR compared with the standard dose CT method without ASIR in CT scans on a phantom and 12 patients. Patient radiation doses were reduced up to 65% using the low-dose IR method, they said. The average dose delivered during the low-dose CT with IR was 470 mGy; the average dose delivered using the standard dose CT without IR was 894 mGy.
Computed Tomography Study Assesses Model for Predicting Recurrence of Non-Small Cell Lung Cancer
January 31st 2025A predictive model for non-small cell lung cancer (NSCLC) recurrence, based on clinical parameters and CT findings, demonstrated an 85.2 percent AUC and 83.3 percent sensitivity rate, according to external validation testing in a new study.
What Emerging CT Research Reveals About Obesity and Post-Op Survival for Non-Small Cell Lung Cancer
January 29th 2025For those without low skeletal muscle mass on CT and myosteatosis, obese patients have a 23 percent lower risk of death than non-obese patients after undergoing curative resection for non-small cell lung cancer, according to newly published research.
