This is an open-label brain PET/CT (positron emission tomography/computed tomography) study
to investigate the diagnostic performance of 68Ga-BNOTA-PRGD2 in evaluation of stroke
patients in convalescence. A single dose of nearly 111 MBq 68Ga-BNOTA-PRGD2 ( ≤ 40 µg
BNOTA-PRGD2) will be intravenously injected into the patients. Visual and semi-quantitative
method will be used to assess the PET/CT images. Changes of 18F-FDG PET/CT, enhanced brain
MRI or CT, and any adverse events will be collected from the patients.
