What WashU Medicine Mallinckrodt Institute of Radiology does

Mallinckrodt Institute of Radiology (MIR) is the academic radiology department of Washington University School of Medicine in St. Louis, Missouri, founded in 1931. It operates as a non-profit academic medical unit providing diagnostic imaging, interventional radiology, and therapeutic radiopharmaceutical (theranostics) services to patients across the St. Louis metropolitan area. Clinically, MIR serves as the sole academic radiology provider for the BJC HealthCare system—including Barnes-Jewish Hospital (Level 1 Trauma Center), St. Louis Children's Hospital (Level 1 Pediatric Trauma Center), Siteman Cancer Center (NCI-designated Comprehensive Cancer Center), and multiple community hospitals—performing 1.8 million+ imaging exams and 16,000+ second-opinion reads annually with a faculty of 100+ fellowship-trained radiologists.\n\nMIR's technology base spans MRI (including a 7T scanner), CT, PET/CT, PET/MRI, mammography, ultrasound, interventional imaging equipment, on-site cyclotron/radiopharmacy capabilities, and five dedicated research centers (Biomedical MR, Biophotonics, Computational Imaging, Neuroimaging Labs, and Precision Radiotheranostics Translation Center) supported by 10 core facilities spanning 35,000 square feet. The institute is the birthplace of PET imaging (Phelps and Ter-Pogossian, 1970s), invented fluoroestradiol (FES) PET imaging for breast cancer (1984), developed early whole-body PET techniques with CTI (1992), and invented cancer goggles for intraoperative tumor visualization (Achilefu, 2015).\n\nMIR's business model combines three revenue streams: clinical professional and technical billings for imaging and interventional procedures (routed through Washington University Physicians with insurance-based reimbursement), externally sponsored research (ranked #2 nationally with $44M in NIH funding and $54M in additional external research revenue), and academic/teaching support from the medical school. Customer segments are split across patients (consumer self-referral for screening and direct scheduling via 855-SAFE-RAD), referring physicians (the primary enterprise channel, supported by a dedicated portal with scheduling, prior authorization, and radiologist consultation), and academic/research users. Education is delivered through a diagnostic radiology residency (one of the largest in the U.S. at 72 residents), integrated interventional radiology residency, and 11 subspecialty fellowship programs.
