Do Pet Scans Show Lung Cancer
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
Pet scans most often use a radioactive form of glucose, the energy source for most of the cells in our bodies. The pet scanner can detect and measure how much of the radioactive glucose analog, f-18 fdg, is in a particular organ or region. The areas using more glucose are hyper metabolic and generally more worrisome. Our brains and sometimes hearts prefer glucose as food, making ...Read more
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

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
5cm Pleural mass in right lung..pet scan show not cancer...is surgery still necessary and what are the risks ..thanks?
Lung mass: Something is missing! There must have been symptoms that led to a pet scan. Unless a biopsy was performed how could your doctor simply say that there was no cancer? I hope there was indeed no cancer but the symptoms that led to the pet scan should be a cause for biopsy. Do the doctors have any idea what the pleural mass might be? Please keep me informed. ...Read more
Pet scan in jan 2013 showed 4 cancerous nodules in lungs from breast cancer. New pet scan july 2013 - lung spots no longer metabolically active; does this mean they are no longer cancerous?
Favorable Response: Pet provides the benefit of early identification of ineffective chemotherapy, particularly metastatic breast cancer, as various alternative treatment options are available & allows patients to be spared the toxicities of ineffective treatments. Complete metabolic response is a great prognostic indicator with significantly increased overall survival compared to patients showing no response. ...Read moreSee 2 more doctor answers
I have a 2 CM nodule and smaller nodules in my lungs. Will be getting a pet scan. How quickly will it spread if it's cancer?
What to do if I have a 2cm nodule and smaller nodules in my lungs, going in tomorrow for a pet scan. if this is cancer, how quickly will it spread?
Need evaluation: proceed with PET scan . ultimately you would need to have a biopsy of the lung mass to establish a diagnosis. if you smoke, please quit. God only knows how quickly it will spread. having said that- it will depend of the biology of the cancer- some cancers are indolent/slowly growing, and others are aggressive . PET scan will show if there is any other suspicious area- lymph nodes or organs. ...Read more
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
