### Description

<p>This is a Notice of Intent, not a request for proposal.&nbsp; The National Institute of Health, Clinical Center (NIH-CC) intends to negotiate on an other than full and open competition basis with the following vendor: Bayer Healthcare LLC.</p>

<p>Acquistion Description:</p>

<p>The Center for Interventional Oncology in the Clinical Center/Radiology and Imaging Sciences and<br />
the National Cancer Institute&rsquo;s Center for Cancer Research conduct highly advanced research in dual<br />
layer spectral computed tomography (CT) imaging, developing new clinical applications. These<br />
ongoing studies require the injection of x-ray contrast under precisely controlled conditions, including<br />
timing, volume, and rate of injection. The specialized contrast injection system is integrated into the<br />
existing CT system and communicates with the CT scanner to initiate the CT scans, coordinating the<br />
sequences and ensuring correct timing. The current system is the same as that which is in use in the<br />
Clinical Department, Radiology and Imaging Sciences. The existing system is at its end of life.<br />
Service will no longer be available. This request is for a replacement injector by the same<br />
manufacturer.</p>

<p>The statutory authority for this sole source requirement is 41 U.S.C. 253(c) (1) as implemented by FAR 6.302-1 only one responsible source and no other supply of service will satisfy agency requirements. THIS IS NOT A REQUEST FOR PROPOSAL.&nbsp; All responsible sources that could provide the required may submit a capability statement that will be considered by email (subject line to reference NOI-CC-OLAO-26-009364) by 12:00 PM eastern standard time on 09/26/2026 to: valerie.gregorio@nih.gov.</p>
