Assessment of image quality and radiation dose in low-dose, low-contrast computed tomography coronary angiogram: a systematic review and meta-analysis
Listen to this summary
The authors aimed to evaluate the image quality and radiation dose associated with low-dose, low-contrast computed tomography coronary angiography (CTCA). Their systematic review and meta-analysis of five studies demonstrated that using an 80 kV setting significantly reduces radiation exposure by 54-56% while maintaining comparable image quality to 100 kV, suggesting its potential for safer use in selected patients.
