RecruitingCranial Ultrasound for Point of Care Intracranial Pathology Detection in PediatricsTo improve patient selection for head CT, a safe and high sensitivity screening neuroimaging modality is needed. Currently many clinicians must make treatment decisions based solely on the patients clinical exam, which has low sensitivity and specificity and low inter-rater reliability. This study is being done to learn more about B-mode cranial point-of-care ultrasound (cPOCUS). Ultrasound has several advantages. It is a safe, non- invasive, low-cost, fast and portable bedside tool without ionizing radiation exposure.
