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 does a questionable 6mm noncalcified nodule anterior right middle lobe of my lung mean?

What does a questionable 6mm noncalcified nodule anterior right middle lobe of my lung mean?

The radiologist is: not sure what to make of this small nodule. If it was to be calcified then it would be one thing. For example an old residual of infection. This is not calcified. This opens up many other possibilities. An old infection is still a consideration. It depends on where it is in the lung, how many and do you have an old study. It may be worthwhile waiting a short period and repeat the ct to check it ...Read more

What does suspicious densities is seen in the right upper lobe and left mid lung means? Is it seious or not? Pls answer.

I have a 3.5 cm. Starburst mass, in my lower right lobe of my lung,so what is next. ?

If possible, this is done through a scope passed down the windpipe. Sometimes that won't reach and biopsy must be done through the chest wall, guided by CT scan. In special cases biopsy is done with a scope through the chest wall or surgically. ...Read more
