Liver Lesions On Cat Scan
This organ plays a major role in metabolism and has a number of functions in the body, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. It lies below the diaphragm in the abdominal-pelvic region of the abdomen. It produces bile, an alkaline compound which aids in digestion via the emulsification of ...Read more
Glucose metabolism: PET with F18 FDG, glucose metabolite, determines glucose metabolism of normal and abnormal structures.For example, sometimes lymph nodes are visualized on CT and do no know whether benign or malignant. In general malignant lesions are more active and have higher metabolism of glucose ...Read moreSee 3 more doctor answers
Not necessarily: Mri and cat scans show anatomical brain changes only, not functional ones. If a dementia is far enough advanced to change brain structures, it would "show up" on these scans. However, there may be a long decline in brain function before that point is reached. There are functional scans which might detect changes before anatomic anomalies can be seen. A normal MRI does not "rule out" dementia. ...Read moreSee 1 more doctor answer
What CT scan protocol is recommended for follow-up scans on pts w/ h/o crc & multiple <1cm cystic liver lesions on right lobe to r/o liver metastasis?
Liver protocol: Ct scan with liver protocol or MRI of the liver would be able to show you in more detail. If there were no liver lesions before and now with multiple liver lesions, ultimately, a liver biopsy should be done to definitely tell you what they are. Your cancer marker also can give you more information. Pet scan should be considered as well. ...Read moreSee 1 more doctor answer

What CT Scan conclusion means? "three arterialized hepatic lesions showing washout on portal venous phase imaging upon background nodular cirrhosis"
Findings. Sx? Biopsy: 1st, the basic problem is nodular cirrhosis - there are signs of liver damage (from what cause, only a doc who knows your history can tell). There are 3 lesions- or nodules- in the liver, fed by an artery, which takes up the dye that was injected at the time of CT scan. The dye washes out, so that's encouraging, but whatever the nodules are, you'll need a biopsy to figure out degree of livr damage ...Read more
3mm hypodense liver lesion in caudate lobe & two 3mm hypodense pancreatic head lesions on CT in setting of carcinoid workup. Can these be tumors?
May or may not be: It takes time and follow up CT scans to see if these tumors are growing in size. if they are not tumors(cancer) it will remain unchanged in size over a period of 3-6 months. A biopsy may be required to confirm it in case these lesions are increasing in size(growing bigger). They are too small to do a biopsy now, need to be at least 1Cm or bigger. ...Read more
