Zwanger-Pesiri Radiology

What Zwanger-Pesiri Radiology does

Zwanger-Pesiri Radiology is an independent, physician-owned diagnostic imaging practice operating 23 facilities across Nassau and Suffolk counties on Long Island, New York. Founded in the mid-1950s as a single X-ray center in Massapequa, the practice has grown into the largest community radiology network on Long Island with 251-500 employees and 12 consecutive years as Best of Long Island's #1 radiology practice. Its service portfolio spans MRI (3T, 1.5T wide/short bore, 1.2T open), low-dose CT, 3D mammography, X-ray including Dynamic Digital Radiography, ultrasound, nuclear medicine, PET/CT, and PET/MRI, delivered through subspecialty-trained, board-certified radiologists organized into dedicated departments for body, women's, musculoskeletal, neuroradiology, cardiovascular, and oncological imaging.

The practice monetizes imaging on a fee-for-service basis through insurance contracts (transaction fees per scan), with specialized services including CCTA with calcium scoring, HeartFlow Analysis, PSMA PET, DTI/concussion MRI, and 3D mammography carrying premium pricing potential. Revenue also flows through a dedicated Personal Injury Division handling Workers' Compensation, no-fault, and attorney-coordinated cases with specialized billing rails (arbitration acceptance, lien acceptance, no-fee affirmation). Multi-language patient support (English, Chinese, Korean), online patient and physician portals, mobile SMS appointment reminders, walk-in X-ray, and same-day appointment availability characterize its consumer-oriented go-to-market.

ZP's competitive positioning rests on four reinforcing advantages: (1) imaging technology on average a decade newer than competing hospital systems, (2) subspecialty radiologists reading only within their expertise, (3) insurance reimbursement rates reportedly 3-4x lower than hospital outpatient imaging, translating to lower patient out-of-pocket costs, and (4) deep Long Island distribution via 23 sites. Technology strategy is partnership-led — integrating best-in-class vendor platforms such as Konica Minolta's Bone Suppression Imaging, iCAD's ProFound AI, HeartFlow Analysis, and NeuroQuant — rather than proprietary AI development. The practice is actively expanding in 2025 with new sites in North Bellmore, Hauppauge (November 2025), and Wading River (summer 2025), and has absorbed the patient base of Neighborhood Radiology.

Partnerships

Three partnerships are on record, tiered core and minor.

• Konica Minolta Healthcare AmericascoreTechnology or Integration · 1 December 2025Zwanger-Pesiri Radiology has implemented Konica Minolta Healthcare's Bone Suppression Imaging (BSI) technology across its 23 locations. The technology digitally suppresses bones in chest X-rays to improve lung visualization and reveal subtle pulmonary abnormalities, enhancing diagnostic accuracy and radiologist efficiency.
• HeartFlowcoreTechnology or IntegrationSince 2018, ZP has partnered with HeartFlow to offer a non-invasive personalized cardiac test to diagnose Coronary Artery Disease. The combination of CT technology and HeartFlow Analysis creates a personalized 3D digital model of coronary arteries with blood flow information previously only available through invasive procedures. ZP was one of the first radiological practices in the area to offer HeartFlow Analysis.
• Image WiselyminorStrategic or Co-development PartnerRadiologists participate in Image Wisely, a program that promotes smart imaging practices and lower radiation dosages for better patient experiences.
