Abstract

Dynamic Cine Magnetic Resonance imaging (MR â�?�?fluoroscopyâ�?) is a rapidly developing technique, which evolves from research and works in progress into routine imaging sequences. This technique is designed to demonstrate some of the physiologic and pathologic processes of the human body in almost real time. MR â�?�?fluoroscopyâ�? offers many advantages over other dynamic imaging modalities (such as x-ray based fluoroscopy, nuclear medicine examinations or ultrasonography) due to its lack of ionized radiation and short acquisition time. These features are particularly important in pediatric and prenatal medicine. The dynamic sequences are based on fast acquisition and organization of images in a sequential-loop, resulting in an impression of observing a real-time movie. The sequences vary slightly in different manufactures but almost any sequence sensitive to flow may be employed. They are easily obtainable from a technical standpoint, and are easily tolerated by patients. These dynamic sequences prove to be valuable tools in functional assessment of intracranial/intraspinal CSF flow dynamics, evaluation of effectiveness of endoscopic procedures, esophageal or bowel motility (and almost any other type of dynamic motion in the human body); evaluation of cardiac contractility and blood flow patterns and joint mobility. Dynamic Cine MR Imaging improves our knowledge of fetal physiology, demonstrates functional impairment of fetal fluids flow dynamics; provides clinically significant prognostic information for pre and postnatal planning and contributes in very careful selection of patients eligible for fetal intervention.

Biography

Tamara Feygin is an Associate Professor of Clinical Radiology in University of Pennsylvania, Perelman School of Medicine, and Staff Neuroradiologist in The Children's Hospital of Philadelphia. She led the development and implementation of magnetic resonance fluoroscopy in clinical practice for assessment of cerebral and spinal CSF flow dynamic in children and fetuses; for assessment of fetal swallowing; for evaluation of phonation in children with velopharyngeal incompetence. She is a dedicated educator and mentor of undergraduate and medical students, radiology residents, and radiology and neuroradiology fellows. She has been invited to present her work nationally and internationally. She is a member of the European Society of Neuroradiology, the Radiological Society of North America, the Society for Pediatric Radiology, and a senior member of the American Society of Neuroradiology.
