However, currently available VAB systems differ from the conventional system (i.e. articulate arm type 11-gauge(G) MMT), and the characteristics of both CNB and VAB have been improved. In CNB, a 14-G needle is frequently used to obtain a larger sample. By contrast, VAB is considered easier to perform because it uses a thinner needle and a lighter, ...
