A new study from a German group compared image quality and radiation dose between second- and third-generation dual-source CT scanners, with single- and dual-energy acquisition, for CT pulmonary angiography

A new study in European Radiology found that specific manufacturer protocols can acceptably limit radiation exposure for ordinary examinations in both second- and third-generation dual-source CT scanners, with the third-generation being more dose-efficient. Dual-energy acquisition provides comparable or superior image quality on both scanner generations.
