Comparative Study
Sonohysterography compared with endometrial biopsy for evaluation of the endometrium in tamoxifen-treated women.
This study was performed to compare endometrial biopsy and sonohysterography for evaluation of the endometrium in tamoxifen-treated women. ⋯ In tamoxifen-treated women, sonohysterography provides a significant improvement in sensitivity for diagnosis of endometrial polyps compared with endometrial biopsy.

Caudal epidural steroid injections are used for the symptomatic treatment of radicular lumbosacral pain syndromes, but incorrect injection placement has been recognized as a common problem with the routinely used unguided technique. We aimed to explore the use of sonography to facilitate this procedure. ⋯ Real-time sonography can facilitate caudal epidural steroid injections.

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.
