Randomized Controlled Trial Comparative Study Clinical Trial
Treated needles: do they facilitate sonographically guided biopsies?
We sought to compare needle visualization and diagnostic yield rates resulting from the use of several commercially available treated needles in sonographically guided biopsies. ⋯ The echogenic polymer-coated needle was the best visualized of all needles evaluated, both treated and untreated. No significant difference was found in diagnostic yield rates, but that may be reflective of the relatively small sample size.
