Article Synopsis
- * The survey revealed significant disparities between men and women, such as fewer women in leadership roles, higher rates of part-time work among female physicians, and a perception that women face more challenges in entering the field and balancing work-family commitments.
- * The findings suggest a need for improved support measures, including flexible work schedules and better childcare options, to promote gender equality and attract young talent in the profession.
Contrast-enhanced CT is the standard imaging technique in oncological objectives. Rates of missed pathologies depend on work experience of the respective radiologists. Thus the aim of this study is to analyze the eye movements of professionals while reading CT images in order to evaluate whether the eye-fixation patterns and search strategies of experienced radiologists could explain higher detection rates of pathologies and whether such patterns can be learned.

Article Synopsis
- The study aimed to create and validate a method for assessing humeral torsion using a single x-ray image, simplifying intraoperative procedures.
- The Humeral Head Offset Index (HHOI) is calculated by comparing the medial and lateral humeral head offsets, and was tested on models and patient CT images to determine its reliability.
- Results showed a strong correlation between the HHOI and humeral torsion, indicating the method's effectiveness for clinical application.
Purpose: The aim was to characterize the framework conditions in academic interventional radiology (IR) in Germany with focus on differences between genders.
Materials And Methods: After IRB approval, all members of The German Society for Interventional Radiology and Minimally Invasive Therapy (n = 1,632) were invited to an online survey on work and research. Statistical comparisons were undertaken with the Fisher's exact test, Wilcoxon rank sum test or Pearson's Chi-squared test.
Objectives: This phantom and animal pilot study aimed to compare image quality and radiation exposure between detector-dose-driven exposure control (DEC) and contrast-to-noise ratio (CNR)-driven exposure control (CEC) as functions of source-to-image receptor distance (SID) and collimation.
Materials And Methods: First, an iron foil simulated a guide wire in a stack of polymethyl methacrylate and aluminum plates representing patient thicknesses of 15, 25, and 35 cm. Fluoroscopic images were acquired using 5 SIDs ranging from 100 to 130 cm and 2 collimations (full field of view, collimated field of view: 6 × 6 cm).
