Dynamic CT for Parathyroid Adenoma Detection: How Does Radiation Dose Compare With Nuclear Medicine?

Objective: Dynamic CT is increasingly used for preoperative localization of parathyroid adenomas, but concerns remain about the radiation effective dose of CT compared with that of Tc-sestamibi scintigraphy. The purpose of this study was to compare the radiation dose delivered by three-phase dynamic CT with that delivered by Tc-sestamibi SPECT/CT performed in accordance with our current protocols and to assess the possible reduction in effective dose achieved by decreasing the scan length (i.e.

Risk factors for anxiety at induction of anesthesia in children: a prospective cohort study.

Background: In children anxiety at induction of anesthesia is a common and important aspect of the psychological impact of anesthesia and surgery. Previous studies examining risk factors for increased anxiety have found contradictory results. This may be due to using small, or highly selective population samples, or failure to adjust for confounding variables.

A cohort study of the incidence and risk factors for negative behavior changes in children after general anesthesia.

Background: Hospitalization and anesthesia can have a substantial psychological impact on children, which may be manifested by negative behavioral change. The primary aims of this study were to estimate the incidence of negative behavior change postanesthesia in a large cohort of children, and to identify the possible risk factors.

Methods: One thousand two hundred and fifty children aged from 3 to 12 years scheduled for anesthesia for a variety of procedures were enrolled.

Awareness during anesthesia in children: a prospective cohort study.

During routine adult anesthesia, the risk of awareness is 0.1%-0.2%.
