Which modality is known for having better spatial resolution?

Conventional radiography is recognized for its ability to provide high spatial resolution, particularly for evaluating bone structures and certain soft tissues. Spatial resolution refers to the ability to distinguish fine details in the image, and conventional radiography achieves this through its specific imaging techniques and the use of film or digital receptors that can capture minute differences in radiographic densities.

In comparison, while other modalities like CT and MRI also offer excellent resolution, they are primarily valued for their detailed three-dimensional images or soft tissue contrast, rather than just spatial resolution alone. Fluoroscopy, on the other hand, is better suited for real-time imaging of movement and does not prioritize spatial resolution in the same way. Thus, conventional radiography’s design and function make it particularly adept at providing the best delineation of structures, leading to its reputation for superior spatial resolution.
