Final Pr. ID: Paper #: 136
Patients undergoing lung and stem cell transplants require serial CT examinations and hence dose reduction techniques are mandatory. The newest 3rd generation dual-source CT scanner incorporates spectral beam shaping at 100 kilovoltage (kVp) using a dedicated tin filter (100 kVp Sn), which improves dose efficiency by removing low-energy photons that contribute little to noncontrast image quality. The purpose of this study was to compare radiation exposure in non-contrast-enhanced pediatric chest CT at 100 kVp Sn imaging and at conventional low kVp imaging in the same patient cohort. Read More
