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

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

Should the lung carcinoid surgery have gone ahead if a few hours before the doc found 4 cysts on the liver.Ct scan?

Should the lung carcinoid surgery have gone ahead if a few hours before the doc found 4 cysts on the liver.Ct scan?

Probably completely: Appropriate. Gut carcinoids are always in the liver if they go to the lung. If there was an indication for surgical management of the lung disease then the liver findings would not change that plan. ...Read more

Results of ct scan?dependent perfusion changes in the lung bases?no evidence for spondylitis significant for patient age are bony bridging.Explain???

Showing your age: This just means that there are no inflammatory changes seen on your spine but some bone spurs that are reaching across disc spaces from one bone (vertebra) to another which is a sign of age related or degenerative changes of the spine rather than a spine arthritis or spondylitis ...Read more

Can a CT scan be wrong in metaststic breast cancer to the lung if the pt is on on chemotherapy and breast cancer was stage 2 grade 3 at diagnosis?

Can a CT  scan be wrong in metaststic breast cancer to the lung if the pt is on on chemotherapy and breast cancer was stage 2 grade 3 at diagnosis?

Read below: Breast cancer can progress or recur in case chemotherapy is not working well against cancer. Ct scan is the best way to look for cancer in the lungs and liver. But it can only show shadows which often require further tests...Either a biopsy or a pet scan if there is any uncertainty about the cause of the shadows. Sometimes radiotherapy can cause shadows on the lungs...So not all shadows are mets. ...Read more

Is paraneoplastic syndrome a mets, cancer like spread from the lung to elsewhere an is it always seen in cat scan ?

Is paraneoplastic syndrome   a mets, cancer like spread from the lung to elsewhere    an is it always seen in cat scan ?

Not metastases: Paraneoplastic syndromes result either from substances produced by a tumor (perhaps a pituitary adenoma making prolactin and causing impotence) or from the immune response against a tumor attacking healthy cells (perhaps the attack on an oat cell lung cancer causing blindness). They have nothing to do with whether the tumor has metastasized. ...Read more

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

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

Saw a 3 mm nodule during a CT scan at the base of my left lung. What could it be?

From nothing: To an early something. The anxiety you are experiencing is given as a main reason to not do screening ct's in smokers. 3 mm is too small to worry about. If it were me, i'd re-ct in 6 months to a year to check change in size. You can google the nlst - national lung screening trial. Do you smoke? Time to stop if yes. Good luck. ...Read more

Just had CT scan for my mcrc, lesions in liver, one in lung, hernia containing low density material, diffuse omental disease what is my prognosis?

Short term: I am sorry to hear of your metastatic colorectal cancer. You have metastatic disease and the ct scan shows omental disease. This would be a good time to get hospice involved. The doctor who ordered the tests will be able to review the findings. Bring a family member to help write down your questions and answers. Again I am sorry to hear about your disease. ...Read more

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
