Background Minimizing the ionizing radiation dose to children is fundamental to pediatric radiology. The most widely accepted imaging examination for evaluating craniosynostosis is computed tomography (CT) of the head, an examination that involves ionizing radiation. Objective To determine if sonography of the cranial sutures is an adequate screening examination for the diagnosis of craniosynostosis...
Purpose More accurate and robust image segmentations are needed for identification of spine pathologies and to assist with spine surgery planning and simulation. A framework for 3D segmentation of healthy and herniated intervertebral discs from T2-weighted magnetic resonance imaging was developed that exploits weak shape priors encoded in simplex mesh active surface models. Methods Weak shape...
High incidence cases associated with back pain include intervertebral disc degeneration (IDD), or disc herniation, in the spinal lumbar region, as well as sciatica, pain in the legs due to IDD. This research aims to provide a more accurate and robust segmentation scheme for identification of spine pathologies, to assist with spine surgery planning and simulation. We are developing a minimally supervised...
Introduction Our objective is to determine the utility of noncontrast Hounsfield unit values, Hounsfield unit values corrected for the patient’s hematocrit, and venoarterial Hounsfield unit difference measurements in the identification of intracranial venous thrombosis on noncontrast head computed tomography. Methods We retrospectively reviewed noncontrast head computed tomography exams performed...
