Musculoskeletal and body imaging fellowship training at UC San Diego Medical Center from 2005 to 2006 grounds Dr. Alexander S. Urioste's diagnostic radiology work at 200 W Arbor Dr Suite 140 in 92103. MRI interpretation for meniscal tears, rotator cuff injury, cartilage defects, and stress fractures serves orthopedic panels including San Diego Orthopaedic Associates Medical Group, Inc., which routes post-injury imaging to radiologists credentialed in musculoskeletal reads. Dr. Urioste completed medical school at Wake Forest School of Medicine in 2000, radiology residency at UCSF from 2001 through 2005, and an internal medicine internship at Mount Sinai Morningside before the UCSD fellowship. His co-authored work in the Journal of Muscle Research and Cell Motility on Dictyostelium myosin genetics and in Neuron on motoneuron trophic-factor deprivation reflects a basic-science background predating clinical imaging practice. Image-guided MSK interventions covering joint injections, tendon sheath aspirations, and ultrasound-guided peripheral nerve blocks cross-refer with The Pain Center San Diego, where fluoroscopic and ultrasound-guided pain procedures are performed on patients with spinal and peripheral joint pain. The highest-complexity reads remain 3T MRI protocols for postoperative knee and shoulder cases that must distinguish residual disease, scar tissue, and expected post-surgical change on cartilage-sensitive sequences.
