Pet Lung Cancer Initial Staging
Several Options: Several tests can help stage lung cancer. A contrast enhanced (injected into a vein) CT is the usual first test. The advantage of a PET/CT (not just a PET) is the ability to look for disease in unexpected places (brain for example) or in areas which appear normal on CT, like small lymph nodes. PET shows areas which are using sugar for energy, as some cancers, including lung, do. ...Read moreSee 1 more doctor answer
Many diseases have specific treatments based on their severity. A disease can have certain criteria to determine their severity and applying this criteria to determine how advanced the disease state is called staging. Most commonly this is applied to cancer, and be determining how far the cancer has spread locally and/or to distant sites a stage of cancer can be ...Read more
Sort of...: The pet scan non-specifically show very metabolically active (consuming lots of energy), and lung cancer and its metastasis fit that category. It is not specific. Benign conditions like sarcoid can also make pet studies glow very brightly as well. Slow growing lung cancer, broncheoalveolar may not be pt avid. ...Read moreSee 2 more doctor answers
Maybe: Most lung cancers will be seen on a pet/ct scan, unless they are very small. But if it's the size of a blueberry or larger, it will be seen. Pet scans show bright spots where cells are using a lot of sugar (see picture). This can be from a cancer, an infection, or inflammation. So a negative pet scan means you probably don't have lung cancer. If you do, it's tiny! i hope you feel better! ...Read moreSee 2 more doctor answers
Can pet scan always diagnose /confirm presence of lung cancer or can only give indication and later biopsy is vital to confirm cancer if a nodule seen?
Bx definitive: A positron emission tomography (pet) scan is an imaging test that uses a radioactive substance called a tracer to look for disease in the body. It is often used to determine the treatment of cancer, if it is spreading, or improving, etc. Used in combination with tests such as ct or mri, it can provide a very high index of suspicion for cancer, but a bx is always definitive and used for tx. ...Read moreSee 1 more doctor answer
No such thing: Pet scan identifies increased cellular metabolism. The suv is a measure of how metabolically active a "spot" or "nodule" is. It does not diagnose. Lung cancer (all cancers) is diagnosed by obtaining tissue and examining by pathologist. Any lung nodule must be thoroughly investigated and closely followed by a comprehensive thoracic team. ...Read moreSee 2 more doctor answers

Life expectancy for lung cancer gone to brain. Pet scan shows no other cancer now, only 1 tumor on brain. Surgery and whole brsin radiation will be?
"oligometastatic": Patients with a single brain tumor as the only site of metastatic disease are called "oligometastatic." the chance of cure, though small, is real. Every cancer specialist has a few such patients. I would strongly recommend aggressive treatment, including either radiosurgery (cyberknife, gammaknife, etc.) to the brain or surgical resection, and again stereotactic or chemoradiation to the lung. ...Read moreSee 2 more doctor answers
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. 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
