Quantification of radiation dose reduction by reducing z-axis coverage in 320-detector coronary CT angiography

OBJECTIVE: To quantify the radiation dose reduction achievable by minimizing z-axis coverage in 320-detector coronary CT angiography (CCTA). METHODS: We retrospectively reviewed 130 CCTAs performed on 320-detector CT that offers up to 16 cm z-axis coverage (adjustable in 2-cm increments), allowing c...
