Time–intensity profiles of different sites. a Cortical sampling site and TIC, the screen shows the contrast-enhanced image (C) As well as the conventional ultrasound image (T). b Medullary sampling site and TIC. c Corticomedullary junction sampling site and TIC. d Plotting of regions of interest (ROIs) analyzed by the software, and then generating the supply curves for each ROI (lower section), these curves represent intensity as a function of time. The above images were derived from our own patients which was approved and agreed the requirement for informed consent by the institutional review board of Peking Union Medical College Hospital (approval number, I-23PJ1284)
