- Reason
- The Neonate Head protocol with the pediatric kernel Hp38 could result in artefacts and possibly lead to a misdiagnosis (i.e. either non-existing blood or liquid is mimicked in the images or actual existing blood or liquid is not depicted as expected). There is also a risk of a potential misdiagnosis in using this protocol for surgery planning. Investigations revealed an incorrect parameterization of the reconstruction algorithm applied for the pediatric head kernel as cause of the problem.
