enhancement pattern
The characteristic way tissues or lesions accumulate and retain contrast material during imaging studies.
Full Definition
Enhancement pattern refers to the specific temporal and spatial distribution of contrast material uptake in tissues or pathological lesions during contrast-enhanced imaging studies. Different enhancement patterns provide important diagnostic information about tissue vascularity, perfusion characteristics, and pathological processes. Common patterns include early arterial enhancement, delayed enhancement, rim enhancement, and heterogeneous enhancement. In vascular imaging, enhancement patterns help characterize vascular lesions, differentiate between various pathologies, and assess treatment response. The pattern is influenced by factors such as blood supply, tissue permeability, and contrast agent properties.
Usage
Usage note: Describe both the temporal sequence and spatial distribution of enhancement.
