Contrast-Enhanced Ultrasound
Microbubble contrast for perfusion assessment without radiation.
What is Contrast-Enhanced?
Microbubble contrast for perfusion assessment without radiation.
How it works: Microbubble contrast agent is injected intravenously. These gas-filled microbubbles enhance the ultrasound signal, improving visualization of blood flow and tissue perfusion. The contrast agent remains within the vascular system for a short period.
Common Uses of Contrast-Enhanced
Liver lesion characterization
Differentiates hemangiomas, HCC, metastases, and FNH with superior accuracy
Renal mass evaluation
Characterizes cystic vs solid lesions and enhances renal cell carcinoma detection
Thyroid nodule assessment
Improves differentiation of benign vs malignant nodules based on vascularity
Advantages

Related Imaging Modalities
Complements CT and MRI by providing real-time perfusion information without radiation. Superior to conventional ultrasound for lesion characterization but limited by depth penetration compared to cross-sectional imaging.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
Ultrasound
Ultrasound uses sound waves to create real-time images. Commonly used for pregnancy monitoring and examining organs like the heart, liver, and kidneys.
