What is a characteristic of an image with low spatial resolution?

An image with low spatial resolution is characterized by blurriness or loss of detail because low resolution limits the ability to distinguish fine features and edges within the image. When spatial resolution is low, the pixel density is insufficient to capture small structures clearly, leading to a mushy appearance where details blend together rather than remain crisp and distinct. This manifests as a lack of clarity, making it difficult to discern specific anatomical features or to evaluate subtle variations in texture or contrast within the image.

In contrast, distinct edges suggest higher resolution, high contrast refers to the ability to clearly differentiate between light and dark areas, and a sharp trabecular pattern would also indicate good resolution that allows for detailed assessment of finer structures. Therefore, the presence of blurriness or loss of detail accurately reflects the implications of low spatial resolution.
