|
What radiographic modality is the best for identifying liver tumors?
|
CT scans is the best imaging technique for both benign and malignant liver tumors

What is the advantage of using CT in visualizing liver tumors?
|
• Using contrast (arterial and portal imaging) increase the number of tumor nodules visualized
• Detection of extrahepatic diseases |
|
|

What is the treatment for benign liver tumors?
|
• Most tumors are asymptomatic
• Treatment only when patient is symptomatic (i.e. physically impinges other organs or disrupts the function of organs) |
|
|
What are the treatment options for hepatocellular carcinoma?
|
• Surgical resection
• Local ablation (ethanol or radiofrequency) • Chemoembolization • Liver transplant |
|
|
What is the treatment of choice for cholangiocarcinoma?
