Doctor insights on: What Does Lung Scarring Look Like On Ct

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

They found a spot or scar on my left lung. After 6 months they want to do a CT guided needle biopsy. What is this?

CT guided biopsy: When a spot is close enough to the chest wall, interventional radiologists are able to use ct scan pictures to guide a small needle into a spot. Normally, when a spot is found, we follow it with ct scans. It it looks like it's getting bigger, we plan for a ct guided biopsy to find out what it is. When the spot is away from the chest wall we consider bronchoscopy vs surgical removal.

Would in lung scarring and things of like like cause crackling or other sounds in the lungs? Or would the be clear- awaiting thin slice CT of lungs...

Rales: Crackles when breathing, assuming they are coming from your lungs, can be related to fluid in the tiny alveoli and bronchioles. This can be from many things including changes in surfactin. If your doc has already ordered a high-resolution ct, wait for the results.

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.

Close Follow Up: Usually scarring on a ct is the aftermath of some sort of inflammatory process. But, sometimes, scars can develop cancers down the line. That is, however, quite rare. Given that you are a nonsmoker, your risk of lung cancer is quite low. But, if you are concerned, would see your doctor and discuss the benefits and risks of getting follow up ct scans.

Did CT chest w/contrast, radiologist said multiple tiny nodular and possible scarring. Pulmonologist said scars could be false results (blood vessel)?

Did CT chest w/contrast, radiologist said multiple tiny nodular and possible scarring. Pulmonologist said scars could be false results (blood vessel)?

What's the question?: Sounds like your chest ct report has relatively minor findings. Tiny nodules are most commonly the result of prior granulomatous infection like histoplasmosis or even infections from pets. We usually never realize we were infected. If there are no nodules larger than 4mm and are not in a high risk group (heavy smoker) there is a less than 1% risk of malignancy.

Please explain what these CT findings mean and thank you so much ahead of time. Pleural based nodule in right upper chest size-2x6mm. A slightly asymmetric biapical plueroparenchymal scarring. Also small calcific densities measuring 3.5 mm in the right l

Please explain what these CT findings mean and thank you so much ahead of time. Pleural based nodule in right upper chest size-2x6mm. A slightly asymmetric biapical plueroparenchymal scarring. Also small calcific densities measuring 3.5 mm in the right l

Most likely OK: Small pleural based nodule is most likely a granuloma (left over from prior infection) but could conceivably be a small cancer. You will most likely be followed with ct, especially if you are a smoker. If there is no growth it is probably just a small granuloma and no biopsy is necessary. Biapical pleural parenchymal scarring is very common, but may also be followed. Calcific densities r likely ok.

My last cat scan said that the scarring in my lungs has gotten a lot larger than before. Should I be concerned with this?

Needs follow-up: Scars should not change significantly, so of the abnormality in the lung is growing in size, it needs to be followed-up / further investigated.

Mild scarring left lower lobe diagnosed by chest X-ray how common is this finding? Scared could progress altho dr not concerned should go for CT scan?

Mild scarring left lower lobe diagnosed by chest X-ray how common is this finding? Scared could progress altho dr not concerned should go for CT scan?

Common: Scarring can occur following previous infection, trauma, lung disease or surgery in chest. Scarring is not uncommon in older patient who becomes more exposed to various pulmonary conditions. There is known association of scars and development of lung cancer.Long period of time between baseline scar and cancer. Other risk factors contribute such as smoking, environment, genes. Ct better defines scar.

There are: Many forms of scarring of the lungs depending on its location, extent and cause. One example is on the Chest xray seen here where there is a large scar on the right mid-lung.

What to do if I have what feels like hyperinflated lungs, although my recent expiratory CT scan shows no air trapping.?

Air trapping: Talk to your doctor. The way to diagnose COPD etc... is with pulmonary function tests, not necessarily CT.

Ct showed abnormalities on kidney and nodules on lungs what could this be?

Ct showed abnormalities on kidney and nodules on lungs what could this be?

CT abnormalities: You need to see a doctor as soon as possible. Nodules on the lungs need to be biopsied. You may have a metastatic tumor in your lungs. Have your physician arrange for a ct-guided biopsy of one of them so tissue can be sent to a pathologist to see what they are. You may also need as well a ct of your kidneys as soon as possible to see if they are responsible for your lung nodules. Good luck.

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
