Pet/ct scans using axumin tracer, approved by fda last year and newly approved by medicare in some areas, are starting to be done at different locations. Since cancer cells intake more glucose than normal cells, injecting glucose into a vein and viewing the computerized image on a scan can reveal where the glucose concentrations.
[] showed that fdg uptake of hcc lesions correlates with the. The liver still shows metabolic activity (6.2 suv). These scans may help distinguish between benign and malignant tumors.

A pet (positron emission tomography) scan combined with a ct scan is a specialised imaging test. For example, the ultrasound will travel through blood in the heart chamber, but the image will show when the echo of the heart is received.

Liver imaging in patients with a history of known or suspected malignancy is important because the liver is a common site of metastatic spread, especially tumours from the colon, lung, pancreas and stomach, and in patients with chronic liver disease who are at risk for developing hepatocellular carcinoma.

The two scans provide more detailed and accurate information about where some cancers are in the body.
