MRI is an excellent diagnostic imaging modality that offers superb contrast without exposing patients to ionizing radiation. The use of MRI for pediatric patients has remained very limited due to the need for anesthesia, high costs and the high incidence of failed studies resulting from ill-fitted coils, poor child compliance and motion artifacts. One of the main obstacles facing the widespread adoption of MRI for children is the lack of pediatric appropriate receive coil arrays. Current coils are bulky, often heavy and semi-rigid, designed as one-size-fits-all. As a result, they are anatomically unmatched for pediatrics and are poorly tolerated by children, increasing the need for anesthesia and leading to a high rate of failed exams. InkSpace Imaging works to create a radically new type of MRI receive coil arrays, specifically adapted to pediatric patients, by using printing techniques. [1,2] Printed coils are inherently flexible, lightweight, and easily customizable at low-cost while potentially achieving improved image quality in clinical settings. In our vision, an ideal system would consist of a collection of inexpensive printed coils designed specifically for each patient and an interfacing kit containing all the electronic components needed to connect to the MRI scanner. The technology is based on seminal work performed by scientists of the University of California Berkeley. A 12-channel printed array has been developed and used in clinical settings to image more than 20 pediatric patients at the Lucile Packard Children’s Hospital. In our clinical study high-quality diagnostic images were obtained, while significantly improving patient comfort.
