Safety Profile and Contraindications

2. CEUS Phases and Timing

Arterial Phase (10–35 sec)
Portal Venous Phase (30–120 sec)
Late Phase (>2 min)

3. CEUS in Benign Liver Lesions

Hemangioma: Peripheral Nodular Enhancement
Focal Nodular Hyperplasia (FNH): Central Arterial Fill-in
Hepatic Adenoma: Homogeneous Hyperenhancement
Cyst: No Enhancement

4. CEUS in Malignant Liver Lesions

Hepatocellular Carcinoma (HCC): Arterial Hyperenhancement with Late Washout
Cholangiocarcinoma: Rim Enhancement, Delayed Washout
Liver Metastases: Rapid Washout in Portal Phase
Angiosarcoma: Early Hyperenhancement + Irregular Washout

5. Comparison with Other Modalities
