Weight-based protocols reduce PET/CT radiation dose

December 28, 2015

Patient-specific, weight-based imaging protocols for FDG-PET/CT can significantly reduce CT radiation dose without compromising diagnostic image quality, according to a study from American University of Beirut in Lebanon.

Researchers reduced radiation dose by 43% and achieved double-digit decreases in lifetime attributable risk for cancer by adjusting CT tube current (mAs) modulation based on factors such as a patient's height, weight, and body mass index (BMI).
