Aims and objectives

CT plays a very important role in the imaging of oncology patients. However, the increasing use of CT in the last few decades has raised concerns regarding the risk of cancer from CT imaging.

CT radiation dose is particularly important in oncology patients as they often require serial surveillance scans to monitor for the effectiveness of treatment, disease progression or recurrence.

The aim of this study was to evaluate if patient CT radiation dose can be reduced without compromising image quality by using a single pass CT chest/abdomen/pelvis (CAP) imaging protocol when compared to the conventional imaging protocol, in oncology patients (1-4).
