8mm lung subpleural lung nodule biopsy with CT fluoroscopy

This 41-years old man had come for a cardiac CT and an incident right lower lobe nodule was found. It showed subtle enhancement (Fig. 1), which made the lesion indeterminate and a biopsy was advised. Using the traditional technique (FIg. 2), the needle could be placed only along the side of the nodule. To get a more central location, CT fluoroscopy was used and under fluoroscopic, real-time guidance, the needle was placed accurately into the nodule (Figs. 3-5). Note the position of the interventional radiologist's fingers and hands on the anterior aspect.

The eventual diagnosis was of a probable old granuloma.
