The number of children with cardiac implantable electronic devices (CIEDs) is increasing at a time of rapid growth in cardiac magnetic resonance (MR) and cardiac computed tomography (CT) utilization. The presence of CIEDs poses challenges with respect to imaging safety and quality. A thoughtful approach to cardiovascular imaging in patients with CIEDs begins with an awareness of the clinical indications to determine the most appropriate imaging modality.

Pencil beam scanning (PBS) protons have been shown to provide improved organ at risk (OAR) sparing, conformality and homogeneity compared to photon techniques including three-dimensional conformal radiotherapy, intensity modulated radiation therapy (IMRT), volumetric arc therapy (VMAT), and tomotherapy. We performed a blinded comparison between VMAT and PBS plans and extend this comparison with a case study of a patient win expander during radiotherapy.

The potential of feedback has been understudied, especially regarding who engages more in electricity conservation. Furthermore, most studies have been limited to the Western context, with only a few that explore Asia.
