Since Mass General acquired an advanced dual-source CT scanner in 2009, researchers in the Department of Radiology have used new scanning methods to minimize radiation dose for cardiac CT.

Mass General leads protocols for managing cardiac CT radiation exposure


An advanced dual-source CT scanner at Mass General


The Mass General Department of Radiology has a long history of researching and developing innovative methods to lower the radiation dose of our exams.

Much of this work focuses on cardiac patients who often require multiple tests to clarify their anatomy and physiology. When faced with lifelong imaging needs, these patients may be particularly concerned with radiation dose.

New scanner technology that reduces scan time and expands physiologic capabilities of cardiac CT has provided researchers with an opportunity to create protocols that significantly lower radiation dose while maintaining high image quality. Our advanced 128-slice "dual-source" CT scanner is featured in several recent articles:
