Pediatric patients are often sedated for MRI scans to ensure images are of diagnostic quality. However, access time for MRIs requiring sedation in is often long due to high patient volumes. In 2014, an MRI Try Without (MTW) program was established at our institution to facilitate eligible patients to ‘try’ their MRI without sedation with the help of a dedicated team comprised of child life specialists (CLS), radiology nurses and scheduling as well as MRI technologists. During their MTW appointment, patients and families met with a CLS who used various preparation tools and methods, such as showing videos and pictures, utilizing a mock MRI, listening to sample noises, rehearsing laying still, and choosing a movie to watch during the MRI. The goal of this program was to decrease the wait time for obtaining an MRI, while ensuring diagnostic-quality images for the interpreting radiologist. Read More

Abdominal Magnetic Resonance Angiography (MRA) has gained favor in pediatric patients due to its lack of ionizing radiation and noninvasive nature. Reports exist regarding incidental findings on body MRA in adult patients. However, the incidental findings in pediatric abdominal MRA have not been previously reported. Our study aims to determine the frequencies, characteristics and categories of incidental findings in pediatric patients undergoing abdominal MRA. Read More

Acute osteomyelitis of the pelvis is an uncommon condition in pediatric patients, with involvement of the ischiopubic synchondrosis (IPS) being particularly rare and often presenting a diagnostic challenge. The bones surrounding the IPS are metaphyseal equivalents, akin to the metaphysis of long bones, which have a slower blood flow and are therefore more susceptible to acute hematogenous osteomyelitis. Additionally, prior to osseous fusion, the IPS appears lucent on radiographs, and fusion can occur asymmetrically across a broad age range. These characteristics complicate the radiographic assessment for IPS osteomyelitis. Patients typically present with unilateral groin or hip pain, restricted hip joint motion, limping, and difficulty bearing weight. Initial evaluations often involve plain radiographs, which may appear normal or show asymmetry at the IPS. The differential diagnosis includes stress reaction, osteomyelitis, post-traumatic osteolysis, or tumors. Laboratory tests, such as white blood cell count (WBC) and erythrocyte sedimentation rate (ESR), can help narrow the differential but may not yield a definitive diagnosis. MRI is the next best step for evaluating suspected osteomyelitis, although it is important to note that abnormal signal at the IPS can be present even in normal cases.

In this educational exhibit, we will: a) Review the factors that complicate the diagnosis of IPS osteomyelitis on plain radiographs, b) Illustrate the range of normal MRI appearances of the IPS, and c) Demonstrate the MRI findings of IPS osteomyelitis. Read More

Inflammatory bowel disease (IBD), including Crohn disease, is a cause of significant morbidity in the pediatric population. Perirectal disease is a Crohn related complication affecting as many as 62% of children. Magnetic resonance enterography (MRE) is being increasingly utilized in characterizing the extent of IBD. Dedicated perirectal disease imaging, such as a T2 SPACE, requires an additional 10-15 minutes of imaging time on an already time constrained modality. The goal of our study was to determine the best imaging protocol for patients without clinically suspicious perirectal disease based on the incidence in this population. Read More
