Clinical Trials Unit (BMEII-CTU)

The BioMedical Engineering and Imaging Institute Clinical Trials Unit (BMEII-CTU) is a modern hybrid between a contract research organization and an imaging core. We specialize in developing experimental imaging endpoints not previously used in multicenter clinical trials.

BMEII-CTU supports industry and federally sponsored multicenter clinical studies, as well as individual investigators interested in using imaging endpoints for their research. Typical services offered include trial design and consultation, multi-modality imaging protocol development, site training and qualification, image analysis, database management, data quality control and publication support. Qualified BMEII-CTU analysts are experienced in the use of FDA approved, 21CFR Part 11 compliant, image analysis platforms and adhere to ICH GCP regulations. Some examples of our work are:

Cardiovascular Imaging

BMEII has pioneered the non-invasive imaging of vascular disease using PET, CT and MRI to visualize anatomical and functional aspects of atherosclerosis and its sequelae. We image and assess the vasculature and other territories such as the airways, heart, spleen, bone marrow, brain and adipose tissue.

Monitoring Disease Progression

Novel imaging endpoints can be used to evaluate the efficacy of a drug, or track disease progression, by imaging patients pre- and post-treatment. Quantitative and qualitative assessment of plaque components, and volumetric analysis of clot burden in the lungs and peripheral vasculature are some examples of imaging endpoints measured by BMEII-CTU for clinical trials.

Novel Application of Radiotracers

BMEII-CTU has expertise in the novel application of radiotracers. For example, 18F-NaF-PET is used to detect bone formation and remodeling. Uptake in plaque is believed to be related to vascular calcification.

Pseudoxanthoma elasticum (PXE) is an autosomal recessive disease that results in calcifications in the skin, eyes and cardiovascular system. Using 18F-NaF-PET in PXE patients can show active calcification, as identified in the bilateral femoral arteries in the video.

Detection of Latent Disease

We can apply innovative imaging techniques for early detection of latent disease. For example, dual-energy CT (DECT) can distinguish different materials based on their relative absorption of X‐rays at different energy spectra.

DECT has been used to visualize gout in the joints, but our capabilities allow us to identify monosodium urate deposits in the vasculature. Quantifying these deposits could help assess treatment efficacy and correlate with future cardiovascular risk.
