Ultrasound and ultrasonically guided biopsy in oncohematology.

Ultrasound, because of its simplicity, safety and accuracy, is considered an important and useful imaging method in the management of patients with hematological malignancies. It is able to evaluate superficial and deep tissues and organs, and to detect their neoplastic involvement or related diseases. It can easily guide percutaneous procedures such as biopsy, thoracentesis, abscess drainage, catheterization of subclavian vein, etc. Percutaneous guided biopsy is very useful in hematological patients, especially those with malignant lymphomas. This technique can provide sufficient tissue to allow histological typing and immunological subclassification. This technique can avoid traditional major procedures such as laparoscopy or exploratory laparotomy. However, ultrasound and ultrasonically guided procedures must be used in conjunction with other imaging techniques such as lymphography, computed tomography and magnetic resonance imaging.
