Doctor insights on: Lung Scarring Ct Scan

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

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

What is the mass found on a lung during a ct-scan be?

Infection, Cancer, +: Infection, hemorrhage, tumors (benign and malignant (cancerous)) fluid and even fibrosis can have a similar appearance. If it is mostly calcified, it is likely benign, old infection called a granuloma. Comparison to older scans can help determine if it has grown. The concern is whether or not it is cancer. Recommend seeing a primary care provider, perhaps a pulmonologist consult and pet/ct. ...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

Can you tell me in january, they done just a CT scan on my lungs and showed nothing and sent me home. I had accurate is the d-dimer for clots?

Can you tell me in january, they done just a CT scan on my lungs and showed nothing and sent me home. I had accurate is the d-dimer for clots?

Not accurate : A negative d dimer is helpful for ruling out pulmonary clots. A positive d dimer is basically useless as it can occur from a variety of reasons. A CT angiogram is close to the gold standard for determining whether there are clots in lungs. Regardless of what the d dimer showed, if the CT was negative and they used contrast for the CT then you are in the clear. ...Read more

Had pneumonia three times in 10 months. Had recent CT scan which showed density on LLL of lung. What could be the cause of the repetitious pneumonia?

Had pneumonia three times in 10 months. Had recent CT scan which showed density on LLL of lung.  What could be the cause of the repetitious pneumonia?

Airway blockage: Seems likely that you have some structural issue of the airway that is preventing clearing of secretions and causing recurrent pneumonia. Could be something you aspirated, something causing compression like a lymph node, or some other type of abnormality. See a pulmonologist and or thoracic surgeon because three pneumonia a in 10 months is abnormal and worrisome. ...Read more

A soft tissue was found on my lung from a CT scan what is my next step?

More info: If the ct appearance is non diagnostic, and there are no old studies for comparison, further evaluation may depend on location and size. If the module is bigger than approximately 1 cm, pet/ ct may be helpful in further characterization. Some nodules are amenable to end a bronchial ultrasound guided evaluation. Biopsy may be needed to obtain an exact diagnosis. ...Read more

2 nodules found in my lungs. 7 and 8mm. smoker for 35 years. Why wait 3 months to see if they grow for 2nd CT scan as opposed to doing biopsy now?

Risk: Inserting a needle or going through your airway to get these small spots can cause more harm including death. This protocol of rescanning can decide if it is indeed cancer. Small growths like these could be noncancerous. Good luck ...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

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
