ECG-synchronized multislice spiral CT (MSCT) allows a significant reduction of cardiac motion artefacts and as a result a virtually artefact-free display of intrathoracic structures. With their advantages in imaging geometry and continuous spiral image acquisition multislice CT scanners provide superior image quality and spatial resolution in these patients. ⋯ In addition the development of time-optimised reconstruction algorithms for retrospective cardiac gating in 8- and 16 slice spiral CT scanners have enabled further improvements in temporal resolution. This overview describes the technique, its clinical indications and the merits of electrocardiographic assistance in MSCT of chest disorders.

Non-accidental head injury (NAHI) in infants is an important but difficult topic. To miss or misdiagnose NAHI potentially has important consequences. The evidence base upon which to base decisions is limited but growing. This article aims to summarise current literature and thinking in this difficult area.
