When spatial resolution is increased, what is the expected outcome in the CT image?

Increasing spatial resolution in a CT image leads to an improved ability to distinguish fine details of structures within the scanned area. Spatial resolution refers to the smallest discernible feature that can be accurately visualized in an image. When spatial resolution is enhanced, the image becomes clearer, allowing for a better representation of anatomy and pathology, facilitating more accurate diagnoses and assessments.

Improved detail means that structures that were previously indistinct or blurred become more defined, allowing radiologists and clinicians to observe nuances in the anatomy that might be critical for evaluation. This is particularly important in complex areas, such as the brain or joints, where small variations can significantly impact clinical decisions.

Other outcomes like changes in radiation dose, artificial noise, or contrast detail are not directly related to the increase in spatial resolution itself. While a higher spatial resolution typically requires more precise imaging techniques, which could potentially lead to increased doses or noise if not managed properly, these are not guaranteed direct consequences of improved spatial resolution.
