FIELD: medical science.
SUBSTANCE: invention refers to medicine, namely to preoperative X-ray diagnostics, and can be used for multipoint 3-D fine-needle aspiration biopsy of sentinel lymph nodes (SLN) in the patients suffering breast cancer. Anaesthesia is followed by intracutaneous periareolar introduction of Sonovue suspension 1 ml. Thereafter, with the patient lying down, the ultrasound transducer is moved bottom-up – from the breast new growth to the axillary region. In B-mode lymph node is visualized and in 2-3 minutes, after the introduction of a contrast agent, microbubbles are recorded in a lymph node in the form of pattern amplification in the contrasting mode. A sentinel lymph node is localized and fine-needle aspiration biopsy is performed: 5 ml syringe is introduced in the directions as in Fig. 2, and biopsy material is taken.
EFFECT: method enables avoiding sentinel lymph node biopsy by increasing a probability of detecting metastatic lymph nodes due to enhanced ultrasonic contrast enhancement.
