Ultrasound-guided regional block (UGRA) of peripheral nerves is now common practice. Nerves, muscle, blood vessels and circumferential perineural spread of local anaesthetic are all seen in real time. However, the utility of B-Mode ultrasound may be limited when adjacent tissues have similar acoustic properties, and several diverse approaches have been taken to improve tissue contrast, particularly in cancer imaging. Examples include: 3D and 4D imaging, software modifications such as harmonics and beam steering, and clinical measurement of the fundamental properties of tissue such as stress and strain. Despite incorporation of new ultrasound technologies into cancer imaging, the practice of UGRA remains restricted to B-Mode ultrasound. Therefore, the objective of this review is to describe the principles of advanced ultrasound technologies, their application to cancer imaging, and their potential use within UGRA.
