Quality of neonatal cranial ultrasound Interpretation among doctors in the Western Cape Metro: a clinical survey
Background: Cranial ultrasound (cUS) is a recommended skill for paediatric and neonatal trainees in South Africa. Surveys in other countries showed inadequate knowledge and subsequently a global trend towards standards and training recommendations. There are no guidelines for training of clinicians …
