Model-Based Iterative Reconstruction in Low-Dose CT Colonography-Feasibility Study in 65 Patients for Symptomatic Investigation

LD MBIR CTC objectively shows improved image noise using parameters in our study. Subjectively, image quality is maintained. Polyp detection shows no significant difference but because of small numbers needs further validation. Average dose reduction of 47% can be achieved. This study confirms feasibility of using MBIR in this context of CTC in symptomatic population.
