Are bright orange spots on pet scan cancer?

Are bright orange spots on pet scan cancer?

Tricky: Not all cancers are bright on pet scans and not all bright activity in a pet scan is cancer. Inflammation/infection can also show bright activity. Pet scans are performed in conjugation with ct (pet/ct) and though pet is great for detecting metabolism, its specificity is not as great. Reading a pet requires care/skill. Normal activity is seen in the brain, heart, liver, spleen, kidneys, bladder. ...Read more

Lung (Definition)

When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

Lumpectomy and radiation last year. Was small amt of cancer in node. Now small shadow on upper right lung CT but radiation on left side. Lung cancer?

Lumpectomy and radiation last year. Was small amt of cancer in node.  Now small shadow on upper right lung CT but radiation on left side.  Lung cancer?

Difficult to say: small shadow can be many different things. In the absence of old studies this could have been there for years. Old study is crucial before jumping to conclusions. Old granulomas from old infections can present the same way. It is best to err on the side of caution and have a follow up study to see if it changes before jumping to conclusions. ...Read more

Sacrum x-ray shows a few small black dots on lower pelvic bone & 2 large white encapsulated spots in pelvic space, what could these anomalies be?

Sacrum x-ray shows a few small black dots on lower pelvic bone & 2 large white encapsulated spots in pelvic space, what could these anomalies be?

Xray: xrays of the sacrum also will show signs of gas and particles in the large intestine. An xray takes 3 dimensions and reduces it to 2 dimensions, overlaying multiple structures into a flat image, distorting things to some degree. Pelvic phleboliths (vascular calicifications) are common. The sacrum also has foraminae where nerves pass, which may appear as dark spots. ...Read more

You may also need as well a ct of your kidneys as soon as possible to see if they are responsible for your lung nodules. Good luck. ...Read more

On a pet scan, are the dark areas cancer?

On a pet scan, are the dark areas cancer?

Yes and no: Areas with cancer are usually hypermetabolic in a pet scan due to the increased uptake of the radioactive glucose by cancerous cells. Looking at an FDG pet scan alone, you can grossly see "dark" areas in the brain, heart, kidneys and bladder and these are due to physiologic distribution/excretion of fdg. Not all "dark" is cancer and cancer is often but not always "dark". ...Read more

This way the body is shown in slices, in any plane, usually axially, but ...Read more
