CONCLUSION

MBIR at 115 mA is both objectively and subjectively equivalent to ASIR at 265 mA, which translated to a dose reduction of 50%. This needs to be validated in clinical population and there is potential for further optimization in pediatric population.

BACKGROUND

In a population with ventriculoperitoneal shunts, patients are often young and require surveillance imaging which can contribute significantly in terms of radiation dose. We aim to assess image quality using MBIR whilst systematically reducing radiation dose.
