Objectives: After studying the article entitled “Correlation of the Stiffness of Hepatocellular Carcinoma and Surrounding Liver Parenchyma by Point Shear Wave Elastography,” you will be able to:
Describe the method that was used to determine the HBS ratio
Describe why the detection of HCC and the determination of liver fibrosis is important
Describe the modalities used to assess for tissue stiffness
What were the three classifications of liver fibrous that were used in this study? Nonsignificant, significant, and cirrhosis Nonsignificant, significant, and severe Normal, moderate, and severe Normal, significant, and severe
Why is the detection of HCC and the determination of liver fibrosis important? HCC can be treated surgically with determination of liver fibrosis HCC and liver fibrosis are considered untreatable with medication Earlier stage of liver fibrosis has a significant chance of regression with antiviral treatment Late stages of cirrhosis will respond well to antiviral treatment
Which of the following modalities is not used to assess tissue stiffness? MRI CT Point shear wave elastography Transient elastography
How is the HBS ratio calculated? HCC stiffness/HCC stiffness – liver back-ground stiffness HCC stiffness/liver background stiffness Liver background stiffness/HCC stiffness Liver background stiffness/liver background stiffness – HCC stiffness
What criteria were used to make the diagnosis of HCC on CT or MRI? Tumor size >1 cm, hypervascular on arterial phase, and washout on portal venous or delayed phase Tumor size >1 cm, hypovascular on arterial phase, and washout on portal venous or delayed phase Tumor size >0.5 cm, hypervascular on arterial phase, and washout on portal venous or delayed phase Tumor size >0.5 cm, hypovascular on arterial phase, and washout on portal venous or delayed phase
