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

Would a radiologist identify multiple 3.4 cm size lung lesions on the outer part of the lung on a chest xray??

Would a radiologist identify multiple 3.4 cm size lung lesions on the outer part of the lung on a chest xray??

Lung nodules/lesions: normally abnormalities larger than 1 cm and sometimes even smaller than 1 cm will be noted by a radiologist interpreting a chest x-ray. Normal structures are not typically mentioned. It's also possible to have lesions visible on a CT scan that won't be visible on a plain chest x-ray either due to size or location possibly hidden by other structures such as the heart, diaphragm, or ribs. ...Read more

Does inflammatory vs malignancy in the remarks of CT scan of lungs with 203cc solid mass mean its cancer?

Does inflammatory vs malignancy in the remarks of CT scan of lungs with 203cc solid mass mean its cancer?

No: No. It is at times difficult to differentiate inflammation/infection from a malignancy on ct. Pet/ct may more helpful where there is suspicion. However, this may also limited in differentiating infection/ inflammation from cancer. That being said, imaging does not arrive at a pathological diagnosis. When possible, any suspicion of lung cancer requires pathological confirmation through a biopsy. ...Read more

What are the chances of lung collapse during a biopsy?

What are the chances of lung collapse during a biopsy?

CT is higher: The risk from a ct guided lung biopsy is approximately 25%. Underlying emphysema would make a collapsed lung more likely. Biopsy of a mass resting against the chest wall would be less likely to cause collapse. I am not sure about the discrepancy between the two answers. I do ct guided lung biopsies all the time, and have the same collapse rates as other docs in my group. ...Read more

A voluminous lesion in the tail of the pancreas also encompassing the greater curvature of the stomach,12cm tumor.is dangerous  fibroscopy?operated?

Cystadenoma: This size lesion expanding to stomach can not be the classic adenoCa. It is probably an islet cell neoplasm or more likely cystadenoma. Since the latter almost always converts to carcinoma, resection of distal pancreas, spenectomy since splenic vein always involved and partial gastectomy must be performed.
