Sub-centimeter Lung Nodule Biopsies

This article from the November issue of the American Journal of Roentgenology discusses the results of 305 CT guided core biopsies / aspirations of small lung nodules, less than 1.0 cm in diameter, over 13 years.

The only major variable that decided success was aspiration instead of core biopsy.

I have been very clear about doing core biopsies for lesions in the body as against FNAC / aspiration for many years now. Tissue today is needed for so much more than just establishing a diagnosis that if we are going to put a needle in the lungs, or other parts of the body, it would be a travesty to come away with only cells, without tissue.

Here is an example of a 7.5 mm lung nodule biopsied earlier this year that turned out to be tuberculosis on histopathology.
