To evaluate the efficacy of ultrasound (US)-guided automated core biopsy of thyroid nodules, 74 biopsies were performed in 61 consecutive patients with an 18-gauge short-throw (1.1-cm excursion) biopsy gun. Results were correlated with diagnoses made at surgery (n = 38) or at sonographic follow-up of at least 6 months (n = 36). Sensitivity, specificity, and accuracy of diagnoses made with automated core biopsy were 84%, 95%, and 91%, respectively. US-guided biopsy with an automated biopsy gun allowed accurate assessment of thyroid nodules.
Background and Purpose: Cerebellar hypoperfusion in the contralateral hemisphere after stroke is well studied and termed crossed cerebellar diaschisis. However, studies of hypoperfusion in the ipsilateral thalamus have been few. The purpose of this study was to investigate the prevalence of hypoperfusion and
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
