Pediatric Imaging
Shreyas Vasanawala

Synopsis

MRI is an outstanding modality for pediatric body imaging, and offers the prime advantage of lack of ionizing radiation. However, it is often under-utilized due to challenges with patient cooperation and reliable image quality. Many of these issues stem from motion artifacts and bloated protocols. This presentation will cover common imaging indications in the extremities, pelvis, abdomen, and chest, providing streamlined protocols for each. Several methods for rapid musculoskeletal imaging will be reviewed. These include targeted protocols and higher-dimensional acquisitions. An approach to abdominal and pelvic MRI will be presented that uses only a couple of sequences to obtain T2-weighted and post-contrast T1 weighted scans. Tradeoffs between various methods of T2 weighted imaging will be reviewed. Further, for MRA and MR venography of the torso, streamlined protocols will be presented that are well-suited to sedated children. Contrast-enhanced imaging techniques that minimize motion will be presented.
