IMR-based reconstruction techniques will allow contrast agents to be detected with greater sensitivity, potentially allowing lower contrast agent doses to be used.

CT images have historically been reconstructed using filtered back-projection algorithms (FBP). Reconstructions via hybrid-iterative (ITER) and iterative model-based (IMR) algorithms have recently become available. These newer algorithms offer lower image noise than FBP. We therefore sought to determine whether newer algorithms would allow improved sensitivity of detection or reduced contrast agent doses via a phantom scanning study.
