What does a shadow in the lung mean on an x-ray?

What does a shadow in the lung mean on an x-ray?

It depends: Shadow is a general term used in describing objects on a chest radiograph. For instance the heart creates a shadow on the x-ray. Can you be any more specific? ...Read more

Lung (Definition)

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

How true is it that the lung X-ray examination result expires or is not valid after 2 weeks? Just heard from a clinic conducting an X-ray test

How true is it that the lung X-ray examination result expires or is not valid after 2 weeks? Just heard from a clinic conducting an X-ray test

No: Not sure what they are referring to when they say expire. Once the x-ray has been taken it is what it is. Your lungs may change within hours after the x-ray is taken, rendering the prior film invalid for medical purposes, but it still stands on its own. Hope I have explained this ok. ...Read more

Can fluid in the lung come back after it looks gone on X-ray ?

Can fluid in the lung come back after it looks gone on X-ray ?

Yes determine cause: It is important to be sure the cause of the pleural fluid is found and treated. Effusions are not always seen well on chest xray and a ct scan or lung ultrasound can detect if there are remaing pockets of fluid (known as loculated fluid). Numerous causes of pleural fluid but important to make sure to evaluate for pus in the fluid, rule out tuberculosis, malignancy, heart failure, pneumonia... ...Read more

My X-ray shows a thickened pleura in the mid-lower area of my right lung due to ptb. Does it cause pain due to pressure on the lung during exertion?

My X-ray shows a thickened pleura in the mid-lower area of my right lung due to ptb. Does it cause pain due to pressure on the lung during exertion?

Pleural thickening: Most of the time does not cause pain, although there are patients who complain of it. We can't predict who do. It may be that it can limit the expansion of your lung but the extent again is individualized. ...Read more

I have COPD and was hospalized in January a x-ray showed nodual on my lung is it usual to remove benign tumors from the lung?

I have COPD and was hospalized in January a x-ray showed nodual on my lung is it usual to remove benign tumors from the lung?

Not if benign: .We wouldn't routinely remove benign nodules from the lung, assuming of course that we're really certain that it's benign. Nodules like this need to be followed for a while by CT scanning to make sure they don't grow. If it seems to be growing at a pretty good rate, we would want to at least biopsy it to make sure it's benign. ...Read more

What is pulmonary fibrosis? And how is it described from an X-ray ? I was told I have hardening of the lung does this mean I have it?

What is pulmonary fibrosis? And how is it described from an X-ray ? I was told I have hardening of the lung does this mean I have it?

Loose Term: Pulmonary fibrosis is a loose term used for numerous interstitial lung diseases. Most often though, it is used for idiopathic pulmonary fibrosis (ipf). X-ray will not be a good modality to evaluate ipf. A ct chest will be helpful. ...Read more

Had the flu 14 days ago, went to the lung dr. Had a lung x-ray, dr. Said my lungs look healthy, but i still cough allot of mucus (ps: have sinusitis).

Had the flu 14 days ago, went to the lung dr. Had a lung x-ray, dr. Said my lungs look healthy, but i still cough allot of mucus (ps: have sinusitis).

Sinusitis: Upper respiratory infections, including sinusitis, may produce large amounts of inflammatory secretions resulting in sputum production and post-nasal drip. Try using saline rinses with a neti-pot, steroid nasal spray and a decongestant (pseudoephedrine, oxymetozaline, etc.). Check with your pharmacist for otc products. They will be happy to help. Good luck. ...Read more

Would an ekg, blood test, chest x-ray, and echocardiogram diagnose a blood clot in the lung?

Would an ekg, blood test, chest x-ray, and echocardiogram diagnose a blood clot in the lung?

Maybe: If the blood test was a "d-dimer" and there were certain specific findings on your x-ray, maybe. The definitive test for a pulmonary embolus (blood clot in lung) is a ct angiogram. However, if you had a negative d-dimer, that makes it extremely unlikely that you have a pe. ...Read more

Abnormal xray cause by small linear density in the lung?

Abnormal xray cause by small linear density in the lung?

Nonspecific: That sounds very nonspecific. Possibilities range from it being absolutely nothing to being something that needs more investigation. I recommend discussing the results with your primary doctor or the interpreting radiologist. ...Read more

Would a radiologist identify multiple 3.4 cm size lung lesions on the outer part of the lung on a chest xray??

Would a radiologist identify multiple 3.4 cm size lung lesions on the outer part of the lung on a chest xray??

Lung nodules/lesions: normally abnormalities larger than 1 cm and sometimes even smaller than 1 cm will be noted by a radiologist interpreting a chest x-ray. Normal structures are not typically mentioned. It's also possible to have lesions visible on a CT scan that won't be visible on a plain chest x-ray either due to size or location possibly hidden by other structures such as the heart, diaphragm, or ribs. ...Read more

An x-ray revealed a light shadow at the base of the right lung. What does this mean? Thanks!

An x-ray revealed a light shadow at the base of the right lung.  What does this mean?  Thanks!

Difficult to say: without seeing the xray. Correctly interpreting chest xrays is a skill that requires years of practice. You should discuss the finding with the doctor who ordered the xray and/or get a copy of the radiologist report, which you might also need to discuss with the doctor. Don't worry about the finding, but don't be afraid to ask questions. If it was serious you probably would have been told. ...Read more

I have had a non productive  for 2 months. Chest X-ray show 3.8 CM mass on my left lung. My dr. Says its proabaly a shadow. What is a shadow?

A bad term: Masses absorb x-rays and cause "shadows" (white areas on an x-ray) the same way your body blocks the sun and causes a dark shadow. A mass is a medical term, a shadow is not. You probably need a chest ct. ...Read more
