Mediso Usa, LLC

Mediso Usa, LLC, based in Arlington, Virginia, supplies preclinical and clinical PET/CT imaging systems and full-service maintenance to the National Institutes of Health and the Department of Defense as a prime contractor, competing exclusively in full-and-open procurements with no set-aside designations. The company is a for-profit limited liability corporation that acts as original equipment manufacturer and exclusive service provider for Mediso-branded animal and clinical imaging systems used in federal biomedical research.

Mediso's federal footprint centers on medical imaging equipment sales and preventative maintenance contracts. The company supplies complete PET/CT, PET/SPECT/CT, and NanoScan systems to NIH institutes and provides factory-certified maintenance, repairs, software upgrades, and technical support. Representative work includes a $1.317 million firm fixed-price purchase order from the Department of Defense Uniformed Services University of the Health Sciences (awarded June 2, 2023) for a pre-clinical PET/SPECT/CT imaging system with integrated animal monitoring, phantom standards, software licenses, five-day on-site training, and one year of warranty and support; a $591,294 full-coverage maintenance contract from the National Institute of Allergy and Infectious Diseases (July 1, 2023, through June 30, 2026) for two MultiScan LFER150 PET/CT animal imagers used in the Laboratory of Clinical Infectious Diseases; and a $453,100 preventative maintenance and service agreement with the National Institute on Drug Abuse (May 17, 2023, extending through May 16, 2028) for a MultiScan LFER 150 PET/CT system at Bethesda, Maryland facilities.

Customer concentration is acute and within the NIH research portfolio. Five NIH institutes account for 85% of recent awards by count and 88% by combined potential value. The National Institute on Drug Abuse leads in award volume (12 awards, $3.2 million combined potential value), while the National Institute of Allergy and Infectious Diseases holds the dollar plurality (8 awards, $4.8 million). The National Cancer Institute (7 awards, $350 thousand), the National Heart Lung and Blood Institute (5 awards, $388 thousand), and the National Institute of Biomedical Imaging and Bioengineering (3 awards, $821 thousand) round out the active set. Two non-NIH outliers include a $1.5 million Defense Logistics Agency Troop Support Medical award and the DoD Uniformed Services award noted above. Across the portfolio, 21 of 41 awards fall under PSC code for maintenance, repair, and rebuild of instruments and laboratory equipment, with the remainder split between equipment sales and specialty imaging and medical imaging supplies.

Activity has declined year over year — four awards in 2022 down to one in 2026 (through mid-July) — suggesting either portfolio transition, customer consolidation onto longer-term contracts, or competitive displacement. Three awards with combined potential value of $781 thousand reach ultimate completion within the next twenty-four months and therefore face recompete. All 41 awards are prime contracts; the vendor does not operate as a federal subcontractor. Mediso operates without SCI-reportable subcontractors across prime work. SCI invoicing ran $376 thousand in FY2022 and $387 thousand in FY2023, representing roughly 0.1 FTEs per year, with government-paid hourly rates ranging from a 10th percentile of $1,596.82 per hour to a median of $1,642.48 per hour and a 90th percentile of $2,208.50 per hour — pricing consistent with specialized equipment service delivery rather than labor-only consulting.
