Positron Emission Tomography (PET) Imaging of Vaso-occlusive Crisis(VOC) in Sickle Cell Disease (SCD).
Enrico Novelli
Summary
The purpose of this study is to find objective biomarkers of vaso-occlusion (blood vessel blockage) in people with SCD. Using information from earlier studies and work being done, researchers have developed a strategy to image VOC, using positron emission tomography (PET). The ability to see and measure VOC in SCD patients can help patient care, by showing when and how a VOC is occurring or going to occur. Studying this method will also help in future drug research, as it will allow researchers to deliver promising new medications that target hyper-adhesion and sickling in people with SCD.
Description
The purpose of this study is to find objective biomarkers of vaso-occlusion (blood vessel blockage) in people with Sickle Cell Disease(SCD). Using information from earlier studies, and work being done at Washington University, a strategy to image vaso-occulusive crisis (VOC) has been developed, using positron emission tomography (PET) for anatomical localization only. 64Cu-LLP2A is the radio tracer used for the study. Aim: To develop quantitative PET imaging of VOC in patients with SCD. The researchers hypothesize that the radio tracer 64Cu-LLP2A uptake increases proportionally to the intensi…
