Figure 5. Drawings illustrate how misalignment of the core biopsy needle can be corrected by adjusting its position relative to the lesion. As shown in A, the long axis of the transducer should be aligned with the lesion and the skin incision site. Drawings B and C illustrate the proper technique, should the needle be advanced to the expected location of the lesion and the needle is not visualized in the field of view: In B, stop moving the needle, and in C, gently rock the transducer to localize the needle (1). In D, the needle is withdrawn slightly (2). In E, the orientation of the long axis of the transducer is corrected by aligning the lesion and the skin incision site (3) and moving the needle slightly toward the lesion (4). The needle should then be "walked" to the lesion (5) by using fine, delicate, and slow movements.
