What Is The Difference Between Lung Nodule And Lung Fibrosis
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
Pleural/subpleural: A pleura is a serous membrane which folds back onto itself to form a two-layered membrane structure. The thin space between the two pleural layers is known as the pleural cavity and normally contains a small amount of pleural fluid. The outer pleura (parietal pleura) is attached to the chest wall. The inner pleura (visceral pleura) covers the lungs and adjoining structures. The subpleura is below it ...Read more
What's a difference between lung nodule and intrapulmonary nodule? What's smallest size in mm that can be detected on CT scan?
No difference: They are two terms for the same thing. The smallest size detectable depends on the type of CT scanner and the technical parameters of the scan. A high resolution, thin section scan could potentially detect lesions 1mm or so in size. ...Read more
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 more
Pulmonary pressure of 27 at the age of 28 I am scared. Am I going to die of lung fibrosis? Doctor concerned and repeating in a year
Normal: Pulmonary pressure of 27 mmHg in a 28 yo otherwise healthy woman is NORMAL and requires no further follow up. If you are still worried, look for a third opinion (since this one is the second) ...Read more
My father is 61 years old and is diagnosed with pulmonary lung fibrosis. What is the ideal diet for such condition?
High scl70, joint pain, fatigue, palmar erythema, telangiectasias, lung fibrosis, livedo reticularis, no hard skin! Can it be Scleroderma if no hard skin?
Will a lung nodule have grown since august 7 until today surgeon a said it will have surgeon b said no. It hadn't grown since may?
See below: Blondie, you are going crazy with this! My suggestion, out of my experience, is that you have to find one doctor that you like and trust and go exclusively by what he/she advises you. Seeking multiple opinions is only going to confuse you to no end, and you will not get a medical education out of healthtap. Again, good luck, and get the thing out to achieve some piece of mind! ...Read moreSee 2 more doctor answers
In 72'-74', I was on a U.S Navy ship, which was full of asbestos. In 05', I was diagnosed with that left lung nodule. May this have caused my nodule?
You're still alive: If the nodule was found ten years ago, and you had no illness as a result, then this is not cancer. If it were cancer, you might have a pretty good case. I'm glad it's not. Asbestosis itself presents as diffuse thickening of the lung texture, or of the pleural surfaces. Most lung nodules in non-smokers (hope that's you) are old histoplasmosis, which is harmless. Thanks for your service. ...Read more
Back in 1972-74, I was on a U.S Navy shift aircraft carrier, which was full of asbestos. In 2005, I was diagnosed with that left lung nodule, which was removed in 2008. In your personal opinion, do you think that may have caused my lung nodule? If so, ple
Many types of tumor: If a lung lesion was noted as solitary and no previous history of underlying disease with bx of mesothelioma then Asbestos has been associated with such lung lesions. Squamous Ca usually derived from smoking and adenoCa from a viral source. At this time worth while to get PET/CAT to assure all path absent from lung or metastatic foci. ...Read more
Big enough: A 13 mm lung nodule warrants a pet/ct scan. This will identify things like calcifications seen in benign nodules and will determine if sugar uptake is high as seen in infection or tumor or low indicating scar. Depending on the likelihood of cancer, a ct guided biopsy is possible in most peripheral nodules greater than 9mm. Lung cancer is increasing in nonsmokers, women and the young in u. S. ...Read more
Yes: Is the short answer. Asbestos can cause several different changes to the chest and lung fields. Pulmonary nodules are just one example. Pleural disease including plaques and calcification as well as mesothelioma are side affects of asbestos. Lung cancer is also a problem. Don't ignore this nodule. Talk to your doctor. ...Read moreSee 1 more doctor answer
Also used to be: Called a coin lesion. A solitary pulmonary nodule may be a primary cancer, or a granuloma or other benign things like a hamartoma or interlobar node. It also may the cause of "false positives" on ct-chest screening. Multiple nodules draw suspicion to traveled tumors. When very small (<5 mm), can be watched for growth; if larger, further work up including removal. ...Read moreSee 3 more doctor answers
50%: A non calcified lung nodule has a 50%risk of being cancer. Diagnosis of cancer is made by pathologist on a microscopic slide of a significant biopsy size. Removal of the whole nodule provides the pathologist with adecuate specimen. Needle biopsy of a lung cancer will miss the diagnosis half the time. So if it is cancer by needle bx it is. Otherwise undiagnostic. ...Read moreSee 1 more doctor answer
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, but: Calcification of a lung nodule frequently indicates that it is benign in nature. It is the noncalcified nodules that are most concerning for lung cancer. And thus the noncalcified nodules that more frequently meet criteria that prompts biopsy of the nodule. Appropriate treatment of lung nodules is best done at facilities with experience ...Read moreSee 2 more doctor answers
