Sharp Rees-Stealy Santee Radiology delivers a five-modality diagnostic imaging suite — DEXA, mammography, MRI, ultrasound, and X-ray — from the first floor of the 86,000-square-foot Cuyamaca Street medical campus. Screening mammography runs on dedicated weekend sessions while diagnostic mammography and MRI operate weekdays, and the department processes orbital MRI referrals from the third-floor ophthalmology team where Namrata Kapoor, MD evaluates retinal and periorbital conditions. DEXA bone-density scans support osteoporosis screening for postmenopausal patients, while musculoskeletal ultrasound evaluates soft-tissue injuries without ionizing radiation. The department sits within Sharp's multispecialty network founded in 1923, feeding imaging reports into a system-wide EHR that gives every ordering physician across 22 locations immediate access to results. OB-GYN providers on the second floor, including Andrea L. Seid, DO, route prenatal ultrasound and diagnostic mammography orders directly to the first-floor suite for same-day turnaround. Highest-acuity studies include contrast-enhanced breast MRI for dense-tissue evaluation, weight-bearing DEXA vertebral fracture assessment, and full-body MRI protocols requiring 60-to-90-minute scan windows on the department's high-field magnet.
