Purpose: The aim of this study was to examine the prevalence of raised state anxiety before and after medical imaging procedures, the prevalence of state anxiety trajectories, and factors associated with postprocedural raised state anxiety.

Methods: A prospective survey was administered to outpatients undergoing elective medical imaging procedures (CT, radiography, MRI, ultrasound, angiography, or fluoroscopy) recruited from one center. Participants completed a self-report survey preprocedure (time 1) and postprocedure (time 2).

Article Synopsis
  • Childhood aggressive behavior (AGG) is significantly heritable, with around 50% of its variation attributed to genetics, as shown in a study analyzing data from over 87,000 children aged 1.5 to 18 years; however, no genome-wide significant SNPs were identified.* -
  • Three significant genes (ST3GAL3, PCDH7, and IPO13) linked to educational traits were found, and genetic analysis revealed moderate to strong correlations between AGG and various psychiatric traits, with notable weak correlations concerning teacher assessments.* -
  • The research also showed negative genetic correlations of aggression with cognitive abilities and age at first birth, alongside strong correlations with smoking behaviors, highlighting complex genetic interactions within childhood aggression.*

Purpose: To examine the percentage of patients with raised state anxiety levels before undergoing a medical imaging procedure; their attribution of procedural-related anxiety or worry; and sociodemographic, health, and procedural characteristics associated with raised state anxiety levels.

Materials And Methods: This prospective cross-sectional study was undertaken in the outpatient medical imaging department at a major public hospital in Australia, with institutional board approval. Adult outpatients undergoing a medical imaging procedure (CT, x-ray, MRI, ultrasound, angiography, or fluoroscopy) completed a preprocedural survey.
