Final answer:
Internal enhancement characteristics on breast MRI can help determine the nature of a mass. Common types include homogeneous, heterogeneous, and rim enhancement.
Step-by-step explanation:
On breast MRI, internal enhancement characteristics of a mass can provide important information for determining its nature. Some common types of internal enhancement characteristics include:
- Homogeneous enhancement: When the mass shows the same degree of enhancement throughout its entire volume, it is referred to as homogeneous enhancement. This can indicate a benign mass.
- Heterogeneous enhancement: When the mass shows uneven enhancement, with some areas appearing brighter than others, it is referred to as heterogeneous enhancement. This can suggest a malignant or suspicious mass.
- Rim enhancement: When the periphery of the mass appears brighter than the central part, it is called rim enhancement. This can be associated with certain types of breast cancers.
