68Ga-NOTA-PRGD2 PET/CT for Integrin Imaging in Patients with Lung Cancer.

ABSTRACT:

Unlabelled

This study was designed to assess the diagnostic value of (68)Ga-NOTA-PRGD2 (NOTA-PRGD2 is NOTA-PEG4-E[c(RGDfK)]2) PET/CT in lung cancer.

Methods

Ninety-one patients (48 men and 43 women; age, 22-82 y) with suspected lung lesions on CT were enrolled with informed consent. Immediately after intravenous injection of 117.7 ± 37.7 MBq of (68)Ga-NOTA-PRGD2, 15 patients underwent dynamic whole-body PET/CT scans for 1-2 h, and the remaining 76 patients underwent whole-body PET/CT scans at 30 ± 10 min after bolus injection. Each patient also underwent standard (18)F-FDG PET/CT for comparison.

Results

No side effect was found after (68)Ga-NOTA-PRGD2 injection. (68)Ga-NOTA-PRGD2 was rapidly cleared from the blood pool and primarily excreted through the urinary system
