Pet Scan For Lung Nodule
Got results for PET scan on lung nodules. Nodules are "undetermined" cuz of size but parotid glands on both side of neck showed "hot". Any relation?
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
Zero: The lowest suv (standardized uptake value - a semiquantitative measure of metabolism) is zero. The maximum suv in a region of interest is called suv max. Generally, if the lung nodule is less than an suv max of 1, it is likely benign. However, there are plenty of non malignant diseases that can have increased FDG uptake, such as healing fungal lung infections, called granulomas. ...Read moreSee 2 more doctor answers
Maybe: Lung nodules smaller than 10 mm (3/8 inch) can be falsely negative on pet because of limitations of the technology. That means the uptake on the scan is not high enough to be suspicious even though the nodule is actually worrisome. However, some small nodules have enough uptake despite their small size. The pet is not a bad idea for a 6 mm nodule, and if positive, means aggressive evaluation. ...Read moreSee 3 more doctor answers

Yes: There are differences in techniques between the ct scan with a pet scan and a general ct scan. Additionally, radiologists may measure a nodule slightly differently. Please look at a ruler and realize just how small 1 mm is. Radiologists routinely are measuring things less than 1 cm or about 3/8 of an inch. ...Read moreSee 3 more doctor answers
Had an MRI of a lung nodule that is non calcified ... Slow growing since 2001... 9mm... Radiologist made diagnoses of it being benign . How can he make such a diagnoses without truly knowing isn't a CT pet scan better to show or even a biopsy?
D/w your MD: It looks like a benign tumor--over 11 years- it grows slowly and the size is only 9mm. If this were a cancer, the growth will be way more rapid than this is. A pet scan has some degree of false negativity when the size is < 10mm. A biopsy is invasive and it's not easy to do when the size is small. Would recommend surveillance only, & quit smoking .If you smoke. (btw, ct scan is better than mri). ...Read moreSee 4 more doctor answers
Is this too much in a 2 month period, 1 pet scan, i ct, 6 x-rays , a brain scan now doctors wants another pet .Lung nodule 1.4 -2.7 suv?
Are subcentimeter lung nodules that have not changed in size since january assumed to be benign if they do not light up on a pet scan. All are 6 mm?
Not necessarily : Six millimeter nodules are small and may not light up in a pet scan even if malignant. However, the fact they are stable is encouraging. I would guess your doc will keep an eye on them unless there's something else that is suspicious for cancer. Good luck. ...Read moreSee 1 more doctor answer

Can you explain results of chest X-ray led 2 cat scan, which led 2 pet scan. results are multiple nodules. what causes lung nodules?
Multiple: There are many causes for pulmonary nodules, which can be broken down into benign or malignant. There are a large number of causes for benign nodules, and 95% of nodules seen on CT scan are benign. If the nodule is large enough, a biopsy may be recommended. The initial move is to see if the same mass was present on a previous scan. PET scans are used to add information, but should not be done firs ...Read more

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
If I've had a CT scan of mu lungs and there was a subpleural nodule found 6mm should I get a pet scan? And could this be cancerous?
Ct scan from 1 month ago showed my lung nodule grew 1 mm. Will a pet w/ CT tell me if its cancer?
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
