What is a benefit of using thicker slices in CT imaging?

• A. Enhanced detail visibility
• B. Reduced dose to the patient
• C. Improved axial image quality
• D. Increased reconstruction options

Answer: (B)

Using thicker slices in CT imaging has the benefit of reduced dose to the patient. When thicker slices are utilized, the amount of radiation exposure during the scan can be diminished because fewer slices are needed to cover the same area. This is due to the incorporation of more tissue in each slice, which allows for a lower radiation dose while still maintaining diagnostic quality. In terms of the other options, enhanced detail visibility generally improves with thinner slices, allowing finer structures to be better visualized. Improved axial image quality often correlates with thinner slices as they can capture more precise anatomical information. Increased reconstruction options are more present with thinner slices as well, offering greater flexibility in post-processing and viewing built from more data points. Thus, the choice of thicker slice thickness effectively balances the need for diagnostic information with the goal of minimizing radiation exposure to patients.
