Holding board certification in diagnostic radiology under California medical license G63334, Mansfield William P MD operates an imaging practice at 406 Ninth Avenue in downtown San Diego's East Village corridor. Subspecialty training in breast imaging, MRI interpretation, and neuroradiology—built through residency at Charles R. Drew University and Loma Linda University Health—supports a referral network that includes Akeso Occupational Health San Diego for workplace injury imaging studies. Morehouse School of Medicine conferred his medical degree in 1987, followed by a transitional internship at UCLA-VA Greater Los Angeles before sequential diagnostic radiology residencies in the Southern California academic system. CT, conventional radiography, and MRI interpretation services extend across the broader Bankers Hill and East Village medical community, including radiology reads coordinated with First Avenue Medical Center in the same downtown district. The most technically demanding reads involve contrast-enhanced breast MRI with computer-aided detection for BI-RADS 4 and 5 lesion characterization prior to image-guided stereotactic core needle biopsy.
