Fine Needle Biopsy
Sample biopsies of cystic and isoechoic nodules using a parallel approach.
This ultrasound-guided parallel approach which is sometimes referred to as the “in-plane” or “long-axis” approach, allows visualization of the needle from the point of insertion down and along the azimuthal plane through to the nodule. The needle is oriented and introduced at the midportion of
either end of the transducer, which is in parallel to the azimuthal
