Smallest nodule biopsied so far

Up to now, the smallest nodule I've ever biopsied under CT guidance was 8 mm. More recently, I've had to do a 6 mm and a 5 mm nodule. The first image shows one of the nodules in the medial segment of the right middle lobe. The second images shows the g.22 needle tip in the nodule. The CT image at the level of the pelvis shows the primary lesion which is a giant cell tumor involving the right iliac crest. Biopsy showed giant cells in the biopsy specimen.
