[|Human|] Hi my dad had a scan done last week on his liver lungs and kidneys. The dr. Called him back today and told him he had to go for an MRI on his liver because the scan on his liver was cloudy and he had a previous scan done 6 months ago and it showed that their were ceses on his liver. We r worried that it may be cancer . What is your take on this.
[|AI|]  If your dads traffic dynamic contrast enhanced MRI shows lesions greater than 2 cm demonstrating classical arterial enhancement is diagnostic of hepatocellular carcinoma (HCC). For lesions 1 to 2 cm in size classic arterial enhancement pattern on both CT scan and MRI is considered diagnostic of HCC. Liver lesions less than 1 cm should be followed closely with periodic repeat imaging. Liver lesions greater than 1 cm that do not demonstrate classical arterial enhancement should undergo tissue biopsy to confirm diagnosis. A blood test called AFP meaning alpha photo protein greater than 200 in a patient with liver lesion greater than 2 cm has a high predictive value for HCC and can be considered diagnostic even without the classical enhancement pattern on imaging. Take care and regards.
