To identify patterns of calcifications and location on abdominal radiography to help diagnose their disease processes. We retrospectively reviewed abdominal x-rays with abnormal calcifications and correlated the findings with additional imaging such as ultrasound, CT or MR. We grouped calcifications by quadrant or diffuse to correlate with the differential diagnosis and disease process. Assessing the location and characteristics of calcifications on abdominal radiography can be highly useful in aiding in the formation of a differential diagnosis and guide next imaging steps.

In the past, neuroblastoma patients frequently had mIBG and diagnostic CT scans performed at separate times. This practice sometimes caused issues in correlating findings from the two imaging modalities. A retrospective review of our entire experience aimed to confirm the added value of optimized co-registered contrast-enhanced diagnostic CT to I-123 mIBG SPECT/CT protocol in children with neuroblastoma. An additional objective was to identify if SPECT/CT improved Curie score assignment vs planar imaging. Read More

PET/MRI (Positron Emission Tomography–Magnetic Resonance Imaging) is a powerful hybrid imaging modality that has gained increasing clinical relevance in pediatric and neonatal imaging over the past decade. It combines the molecular imaging strengths of PET with the superior soft tissue contrast and functional capabilities of MRI, enabling both whole-body and targeted imaging in a single session. In pediatric imaging, where minimizing radiation exposure is critical and conditions often involve subtle functional or metabolic changes, PET/MRI has emerged as a powerful problem-solving modality. Additional advantage of PET/MRI in pediatric patients is reduction in the number of necessary single examinations and thus reducing the number of sedations and radiation exposure when compared with PET/CT. PET/MRI has been established as a clinical imaging modality with a wide range of applications across pediatric oncology, neurology, cardiology, infectious/ inflammatory disorders, and rheumatology. It can be utilized for presurgical planning for epilepsy, detection and staging of tumors. Beyond detection and characterization of tumor lesions, PET/MRI is highly effective in providing relevant secondary information about tumor-related or therapy-related complications. Additionally, PET/MRI is helpful diagnostic tool in unusual or challenging clinical situations such as discrepant findings from other diagnostic tests, nonspecific clinical findings, or inconclusive prior imaging findings, especially in children with fever of unknown origin. In such settings, PET/MRI can be used as a problem-solving tool to provide guidance regarding patient management when identifying disease foci or biopsy targets or when ruling out the presence of macroscopic malignancy or active inflammatory processes. This exhibit demonstrates the unique diagnostic value of hybrid PET/MRI in complex pediatric imaging and to highlight its role as a comprehensive, multiparametric tool in evaluating a wide spectrum of challenging pediatric conditions through clinical cases. The exhibit will be educational for radiologists, nuclear medicine physicians, and pediatric specialists on the strengths, clinical applications, and practical considerations of PET/MRI in children.
