Comparison of N1S1 empty vector and HSE-luc rat tumor models by 3.0T Fast Spin Echo (FSE) T2 MRI and 2D bioluminescence imaging (BLI) 7 days post cell injection. Representative coronal FSE T2-weighted MR images show (A) empty vector (white arrow) and (B) HSE-luc tumors (white arrow). Corresponding 2D BLI images show bioluminescent signal (radiance; p/s/cm2/sr) in (D) HSE-luc tumor (white arrow) but no signal in (C) empty vector tumor.
