Since its introduction in the 1970s computed tomography (CT) has revolutionised diagnostic decision making. However, the rapid increase in CT utilisation has brought with it significant medical and public concern with regards to the doses of ionising radiation delivered during scanning (1). There is an inherent responsibility on the medical community to keep radiation doses “as low as reasonably achievable” (ALARA). With improved technology, significant advances have been made with regards to radiation dose reduction (1). One of the most significant advances in dose reduction...

Here we will outline some of the previous and ongoing work carried out within University College Cork, Cork University Hospital and the Mercy University Hospital which has helped to begin to clarify the role that iterative reconstruction can play within the clinical sphere. A prospective feasibility study of sub-millisievert abdominopelvicCT using iterative reconstruction in Crohn’s disease (12) In one of our earliest studies assessing the feasibility of the clinical application of a low dose protocol with ASIR reconstruction we recruited 40 patients to undergo two...

In this short poster we have demonstrated some of the current roles and potential future clinical applications of advanced iterative reconstruction techniques within the clinical sphere. While its current utility remains as a research tool, this research has begun to elucidate its potential future clinical application. The widespread utilisation of these low dose techniques will require further research validation within larger patient cohorts suffering from differing disease entities, but these initial feasibility studies demonstrate considerable promise.

Cork University Hospitalis the largest university teaching hospital in Ireland and the only Level 1 Trauma centre in the countrywith over 40 different medical and surgical specialties on the campus. The radiology department in Cork University Hospital has close links with University College Cork and one of the primary research interest within the department is regarding dose optimisation in computed tomography
