Doctor insights on: What Does Clear Lungs In A Ct Scan Mean

Share

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

Ok so I got a CT scan of the abdoman done with contras. Said lung base was clear so dose that mean I do not have a hiatl hurnea?

Ok so I got a CT scan of the abdoman done with contras. Said lung base was clear so dose that mean I do not have a hiatl hurnea?

Maybe: The comment about your lung bases specifically refers to your lungs and is actually irrelevant to whether or not you have a hernia. If you did have a hiatal hernia the radiologist should have commented on it directly. If there is no mention of a hernia, you probably don't have one. You can ask your doctor to review the ct scan with that specific question in mind if you want to be sure. ...Read more

Ct scan shows lung polyps on my lungs. What does this mean for me?

Ct scan shows lung polyps on my lungs. What does this mean for me?

Need to know more: About the findings on a ct. I am not familiar with the term "lung polyps".

Pulmonary nodules are quite common, and depending on appearance, density and stability (if an older scan is available), can be accurately classified as benign.

Unfortunately, although most are benign, for many patients, we cannot tell for sure on 1 scan, so further workup is necessary.

Please discuss this with your doc. ...Read more

My mother was just told that we found a density in her lungs from a CT scan? What does that mean?

My mother was just told that we found a density in her lungs from a CT scan? What does that mean?

Different things...: It could be related to different problems: a completely benign lesion, tumor, infection, inflammatory nodule (for multiple reasons), lymph nodes which most of the time are benign. If significantly large it might need biopsy but that requires a Pneumologist (Lung doctor) opinion and evaluation in order to decide the next step and inform more about diagnosis. ...Read more

I just had a CT scan of my chest which shows a 3cm lung bullae. What does this mean? How bad is it and what could treat it?

I just had a CT scan of my chest which shows a 3cm lung bullae. What does this mean? How bad is it and what could treat it?

No treatment: A bullae is an air filled space in the lung that has replaced the normal lung structures. Bullae can be a result of infection, inflammation, smoking. There is no treatment, it is best to think of them like a scar. ...Read more

My ct scan says I have dependent atelectasis changes of the lung bases identified what that means?

My ct scan says I have dependent atelectasis changes of the lung bases identified what that means?

It most: Likely is not significant, and simply related to gravity and/or a less than complete depth of inspiration at the moment of the scan. Atelectasis in this case means that small portions of the lung are not filled with air/collapsed. It is relatively common as an incidental finding on CT. ...Read more

I have a "shadow" on my lung. Doctor ordered a CT scan, and it showed to test further, what does this mean?

Safety first: It just means that your doctor is doing his due diligence. The CT scan probably shows something in the lung that is not expected to be there. It could be an abnormal vessel, fluid, lymph nodes, scarring or a mass. It depends on what further testing your doctor is requesting. If you could give more information in terms of what further testing your doctor is recommending it would be helpful. ...Read more

Does inflammatory vs malignancy in the remarks of CT scan of lungs with 203cc solid mass mean its cancer?

Does inflammatory vs malignancy in the remarks of CT scan of lungs with 203cc solid mass mean its cancer?

No: No. It is at times difficult to differentiate inflammation/infection from a malignancy on ct. Pet/ct may more helpful where there is suspicion. However, this may also limited in differentiating infection/ inflammation from cancer. That being said, imaging does not arrive at a pathological diagnosis. When possible, any suspicion of lung cancer requires pathological confirmation through a biopsy. ...Read more

What's it mean if CT scan says I have a 4 mm nodular density in lower left lung postero-laterally? In 2012 it was at 3mm now in 2015 it was 4mm

Depending on how: The scans were performed, they may or may not be reliably comparable when measuring tiny nodules. Additionally, studies show significant intra-observer variability when measuring small nodules. So the first order of business is having one person look at both scans and determine if the size has really changed. If yes, further workup might be needed. If no, then probably nothing needs to be ddone ...Read more

Had lower left pneumonia March 4. Right lung had some fluid. Ct scan yesterday showed left lung clear. Right small fluid and atelectasis. What now??

Resolving pneumonia: Do you have an incentive spirometer to encourage deep breathing and expansion of the lung? You can buy them online, even from Amazon or a health supplies store/site. Blowing an instrument, singing, blowing up a balloon, and simple deep breathing exercises as well as being more active out of bed will help resolve it. ...Read more

Is it true that the primary tumor in small cell lung cancer is often occult? Does this mean even a CT scan can't see it? Do we only detect on spread

Is it true that the primary tumor in small cell lung cancer is often occult? Does this mean even a CT scan can't see it? Do we only detect on spread

At some point: In its development, every cancer is "occult" because it originates on a microscopic level. CT has a high sensitivity for detecting lung cancer, approximately 95%, so CT will detect the vast majority of lung cancers. ...Read more

I've had two chest xrays recently. They were clear is there a high chance they could miss lung mets? The hospital won't give me a ct scan on the chest.

I've had two chest xrays recently. They were clear is there a high chance they could miss lung mets? The hospital won't give me a ct scan on the chest.

CT has high dose: Initial chest and abdomen CT for staging is often done for many primary cancers. The need for CT depends on the primary tumor mostly due to the likelihood of mets. Given the type and size of the cancer. An old article: "The significance of pulmonary nodules detected by CT but not by chest radiography in tumour staging" in Clin Rad 44:6 Dec 1991, Pp 410-412 http://www. Sciencedirect.

What exactly does intersitial lung scarring mean? And is a bad sign they want to do a high resolution CT scan of my lungs?

What exactly does intersitial lung scarring mean? And is a bad sign they want to do a high resolution CT scan of my lungs?

Interstitial lung: Scarring is the end result of a healing and repair process. The interstitial tissue of the lung surrounds the airways. A high resolution ct scan of the lung will help your doctors determine the underlying cause by examining the patterns of the scarring on ct scan. Depending on the extent of the scarring, breathing can be affected or not. Please follow up with your physician. ...Read more

Few fibrotic densities at the lung apices on low dose CT scan. What does it mean? I've never had any kind of lung disease

Few fibrotic densities at the lung apices on low dose CT scan. What does it mean? I've never had any kind of lung disease

Fibrosis: These strands of fibrous tissue represent scarring from a prior inflammatory process, probably old infection and could have been an old tuberculosis infection which you fought off. There is no sign of active lung infection. For more opinion the radiologist or a pulmonologist could be consulted. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
