Share

Lung (Definition)

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

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.

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

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
