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

Chest CT scan showed nodules are gone. Report also stated granulomatous disease. What does that mean? I don't have follow up until next week.

Chest CT scan showed nodules are gone. Report also stated granulomatous disease. What does that mean? I don't have follow up until next week.

Benign: Granulomatous disease is usually caused by prior infection by histoplasma fungus. This is benign and quite common. Nothing you describe sounds worrisome.

What does it mean, when my chest CT scan shows that I have multiple patches of ground glass infiltrates, and should I be worried because my doctor isn?

What does it mean, when my chest CT scan shows that I have multiple patches of ground glass infiltrates, and should I be worried because my doctor isn?

Probably chronic: Usually these are findings due to prior swelling or infection in lungs; even based on where you grew up. We use stability on cts to confirm benign nature. Sometimes treatment w/ antibiotics considered. Biopsy considered with hi risk though age & smoking history important.

What does following mean on chest CT scan report: "No evidence of osteoblastic or osteolytic lesions is identified in bones of the chest." Thank you?

What does following mean on chest CT scan report: "No evidence of osteoblastic or osteolytic lesions is identified in bones of the chest." Thank you?

It means: There are no bone lesions or abnormalities to suggest bone malignancy/metastases. In other words, normal.

Had a early cdt lung blood test only one that was just barely elevated was the mage4. I have also had chest CT scan that was normal. This means what?

Had a early cdt lung blood test only one that was just barely elevated was the mage4. I have also had chest CT scan that was normal. This means what?

Were they: Looking for a blood clot, or pulmonary embolus, in the lung? If so the ct scan should rule it out but wait for better advise! I'm not sure what a cdt lung blood test is nor the mage 4 but that was probably the screening test to get the ct which was negative. Wait for a better opinion but the ct, i'll bet, ruled it out. I'm gonna try to refer you to a genius pulmonary guy in my online network.

What does this mean chest ct scan. Mild infiltrates, left lower lobe may represent discoid atelectasis and or pneumonia, mild left pleural effusion..

What does this mean chest ct scan. Mild infiltrates, left lower lobe may represent discoid atelectasis and or pneumonia, mild left pleural effusion..

CT scan: Proper interpretation of CT or "cat scan" results is a tricky proposition and requires a physician to clinically correlate with multiple factors. The findings above may simply represent excessive mucus or possibly an infection. An effusion means there is some type of fluid in or around the lungs.

Had chest ct scan done due to abnormal chest x-ray the ct scan says small pluralparenchymal opacity in left lung base adjacent several cysts what does it mean?

Had chest ct scan done due to abnormal chest x-ray the ct scan says small pluralparenchymal opacity in left lung base adjacent several cysts what does it mean?

Mgt: There may be several possible conditions associated with these findings. Infections may cause cysts. I would suggest a TB test and uploading the scan to your virtual EMR.

What are intrapulmonary lymph nodes? Are they the same as preffisurral nodules and if they are found on chest ct scan is this abnormal?? Or Cancerous?

What are intrapulmonary lymph nodes? Are they the same as preffisurral nodules and if they are found on chest ct scan is this abnormal?? Or Cancerous?

Explanation: No, it is not the same. Intrapulmonary lymph nodes are abnormal findings, but could be benign!! And accidental findings related old infection. You have to discuss this with your doctor, please.

3mm preffisurral nodule found on chest ct scan. Report says most likely representing intrapulmonary lymph nodes. Could this be cancerous? How likely?

3mm preffisurral nodule found on chest ct scan. Report says most likely representing intrapulmonary lymph nodes. Could this be cancerous? How likely?

Very small: Lymph nodes that are 3 mm are very small. Usually a cancer of the lung will be seen on CT scan and have lymoh nodes of 1 cm and multiple. Why did you get ct scan? You will need to see and discuss with your ordering doctor. Do you have a life style at risk like smoking? And other factors. For any risks see and discuss with a thoracic surgeon.

What are the risk of chest CT scan?

What are the risk of chest CT scan?

Risks include....: Radiation imparted to the body as a part of the scan. 1 ct scan of the chest is the equivalent of about 5, 000 chest x-rays. This sounds like a high number, but in reality, if you only receive 1 ct scan, the overall risk of developing cancer or other complications is very low. The information gained from a ct scan versus a single chest x-ray is much greater and can aid in diagnostics.

Why might someone need a chest CT scan?

Why might someone need a chest CT scan?

Chest CT: Including but not limited to: 1) Abnormal chest xray, 2) Persistent clinical symptoms, 3) Smoking or other inhalational exposure where chronic lung disease or cancer is suspected, 4) Chronic lung disease/fibrosis of some other cause, 5) Cardiovascular abnormalities. Basically there are lots of reasons depending on your history or symptoms. Talk with your primary doc and your radiologist!

What are the risks of a chest CT scan?

What are the risks of a chest CT scan?

If you keep it limit: There are none as long as it is without contrast. With contrast there is always a small risk of an allergic reaction. As long as the number of these scans is limited then the risks from radiation from the x-rays is very limited.

Is it possible to get lymphoma from one chest CT scan?

Is it possible to get lymphoma from one chest CT scan?

Not sure what you...: ...mean but if you are asking if the radiation exposure from just one CT scan is enough to cause cancer, I think that would be exceedingly unlikely. There are inherited traits that lead to increased cancer risk with radiation exposure but even then it would be a very rare occurrence. Cannot say it is impossible, though. That is why scans have to be ordered when truly necessary, not capriciously.

What is the risk of getting leukaemia from one chest CT scan?

Extremely low: The radiation dose from one cat scan is pretty low by itself. If you were having multiple cat scans for many years that would be more dangerous from a radiation standpoint.

What organs will a chest CT scan show with and without dye?

What organs will a chest CT scan show with and without dye?

There are: Different ways to perform a chest CT, depending on what your doctor is looking for. A "routine" CT will show lungs, mediastinum, aorta and great vessels, heart, ribs, upper abdomen, thoracic spine.

What kind of complications might happen from a chest CT scan with dye?

What kind of complications might happen from a chest CT scan with dye?

Allergy: The main risk is concern for an allergic reaction to the contrast dye. Damage to the kidney is also a big concern. The good thing is that the kidney can usually recover from this on its own with IV fluids and careful observation.

When you have a chest CT scan is it typical to do a set up lower dose scan before the actual scan? Or was I scanned twice? Scared about rad dose :\

When you have a chest CT scan is it typical to do a set up lower dose scan before the actual scan? Or was I scanned twice? Scared about rad dose :\

Yes,: The initial scan or "scout" is used to plan the actual scan. Otherwise there is no way other than guessing to determine whether the body part to be scanned is adequately covered, and there is also a danger of scanning more area than is actually necessary.

What cancers do 1 chest CT scan cause?

What cancers do 1 chest CT scan cause?

Non: The potential for a cat scan of the chest causing cancer is non. One would need frequent scans to even be associated with cancer. Obviously in a very young patient, the tissue is more sensitive to radiation and as such radiation to the chest from mammograms are of no consequence in the patient over 50, but in a patient under 30 radiation exposure does put the patient at risk.

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
