(a) CT images of different concentrations of La-BFO solutions. (b) X-ray attenuation of intensity in Hounsfield units (HU) of La-BFO as a function of concentration. (c) In vivo CT images were captured at 0, 0.5, 1, 1.5, 2, and 2.5 h after intravenous administration of La-BFO (10 mg kg− 1). (d) The average intensity of CT signals from the tumor after intravenous administration at different times. (e) MRI images of different concentrations of La-BFO solutions. (f) In vitro T2 signaling intensity of La-BFO with different concentrations. (g) In vivo MRI images were captured at 0, 2, 4 and 8 h after intravenous administration of La-BFO (10 mg kg− 1). (h) Schematic of in vivo imaging
