This study intended to compare the dose delivered to patients and image quality in a clinical routine abdominal CT scan with no iterative reconstruction techniques (IR) relative to an examination conducted on a scanner with IR.
Case objectives
This is a retrospective study of 30 patients who underwent two abdominal examinations: one on a 64-slice scanner without IR and another one on a 256-slice scanner with IR. The patients, on medical follow-up for a chronic abdominal disease, had an exam on each scanner using the same protocol comprising an abdominopelvic time portal phase.
