What does the term "resolution" refer to in imaging?

In imaging, the term "resolution" specifically refers to the ability to distinguish small details within an image. High resolution means that the image can clearly show fine details and structures, allowing for better interpretation and analysis of what is depicted. This aspect is critical in radiology, as it affects the diagnostic quality of images; clear differentiation between closely spaced structures can be vital in detecting pathology.

Resolution can be influenced by several factors, including the quality of the imaging equipment and the techniques used during acquisition. An image with high resolution will allow a radiologist to identify subtle changes, which is paramount for effective diagnosis and treatment planning. Understanding resolution helps practitioners appreciate the limitations and capabilities of various imaging modalities, impacting clinical decision-making processes.
