What does ROI stand for?

ROI stands for "Region of Interest," which is a key term in imaging and radiology. In the context of fluoroscopy and other imaging modalities, the region of interest refers to a specific area within the imaging field that is selected for closer examination or analysis. This could be a targeted area that a physician wants to assess for abnormalities, measure quantitatively, or enhance for clearer visualization.

By isolating a region of interest, radiologists can focus their evaluations, potentially improving diagnostic accuracy and guiding treatment decisions effectively. It allows for enhanced processing and analysis of that specific area, which is especially useful when analyzing complex images with multiple structures.

Understanding ROI is essential in imaging procedures because it highlights the importance of focusing on specific parts of an image to obtain more relevant clinical information while minimizing irrelevant data. In this way, ROI plays a crucial role in ensuring efficient and effective diagnostic imaging practices.
