Synopsis
Sickle cell disease (SCD) causes vaso-occlusion, ischemia, and end-organ infarction that causes acute pain episodes, also known as vaso-occlusive crises (VOC). Understanding the mechanism underlying VOC is critical to identify patients at risk and for accurate diagnosis while in VOC. PET imaging with the probe 68Ga-PRGD2 that binds integrin αvβ3 identified areas of increased binding of sickle RBC to the endothelium in VOC. Simultaneous PET-MR imaging could provide additional information on tissue changes associated with VOC. Thus, we imaged a patient with SCD with 68Ga-PRGD2 in combination with MRI by using PET-MR 3T scanner.
