1. To review the contemporary literature and present an updated list of musculoskeletal and non-musculoskeletal imaging findings of patients with autoinflammatory diseases in our hospital. Most of these patients are found to have a genetic mutation that is responsible for their disease. 2. To present follow-up imaging findings, when available, and correlate those with patients’ symptoms and type of treatment administered in approximately 40 patients with autoinflammatory diseases such as Cryopyrin-associated autoinflammatory syndrome, familial Mediterranean fever, PAPA (pyogenic arthritis, pyoderma gangrenousum, and acne) syndrome and much more. These findings can be related to disease progression, treatment response or treatment-induced changes. Read More

Despite being recognized as a secondary sign of appendicitis, no clear definition exists about the amount of intra-abdominal fluid considered physiologic in children. The purpose is (1) to assess the amount of intra-abdominal free fluid by US and MRI in children with suspected appendicitis, (2) to detect the performance characteristics of US for detecting free fluid, and (3) to determine the association between fluid volume and perforated appendicitis. An additional ex-vivo study was done to assess the validity of US measurement abdominal free fluid volume using phantoms. Read More

1. To determine short-term interval changes in T2 maps of knee cartilage of healthy boys before and after a 2-minute knee-squat exercise at 1.5T and 3T MRI; 2. To determine interval changes in T2 maps pre-exercise at 1.5T vs. 3T, and post-exercise at 1.5T vs. 3T; 3. To determine interval changes pre- and post-exercise among minimal-, moderate-, and high-activity subjects at 1.5T and 3T; and 4. To determine inter- and intra-reader reliability of 1.5 and 3T values. Read More
