Abstract

OBJECTIVES

Evaluation of structural changes and the weight given to radiation exposure of interventional radiology (IR) contributions at the Congress of the German Radiological Association from 1998 to 2008.

METHODS

All IR abstracts were evaluated for type of contribution, design, imaging modality, and anatomic region. Weight given to radiation exposure was recorded as general statement, main topic and/or dose reduction. Statistical analysis included calculation of absolute/relative proportions of subgroups and ANOVA regression analyses.

RESULTS

Out of 9,436 abstracts, 1,728 (18%) were IR-related. IR abstracts significantly rose to a maximum of 200 (20%) in 2005 (P = 0.048). While absolute numbers of scientific contributions declined, educational contributions significantly increased (P = 0.003). Computed tomography (CT) and magnetic resonance imaging (MRI) were the main IR imaging modalities, with growing use of CT (P = 0.021). The main body regions were vessels (45%) and abdomen (31%). Radiation exposure was addressed as a general statement in 3% of abstracts, as a main topic in 2%, and for dose reduction in 1%, respectively. During the study interval a significant growth of dose reduction abstracts was observed (P = 0.016).

CONCLUSIONS

IR emerged as a growing specialty of radiology, with a significant increase in educational contributions. Radiation exposure was rarely in the focus of interest but contributions relating to dose reduction demonstrated a significant growth during the study period. Main Messages • Interventional radiology emerged as a growing specialty at the German radiological congress. • Significant increments of educational and prospective research contributions could be observed. • Despite a significant trend towards computed tomography, radiation exposure of IR was rarely in the focus of interest. • Contributions related to dose reduction demonstrated a significant growth during the study period.

摘要

目的

评估 1998 年至 2008 年德国放射学会大会上介入放射学（IR）贡献的结构变化和对辐射暴露的重视程度。

方法

评估所有 IR 摘要的贡献类型、设计、成像方式和解剖区域。将对辐射暴露的重视程度记录为一般性陈述、主要主题和/或剂量减少。统计分析包括亚组的绝对/相对比例计算和 ANOVA 回归分析。

结果

在 9436 篇摘要中，有 1728 篇（18%）与 IR 相关。IR 摘要在 2005 年达到 20%的最大值（P=0.048），呈显著上升趋势。虽然科学贡献的绝对数量有所下降，但教育贡献显著增加（P=0.003）。计算机断层扫描（CT）和磁共振成像（MRI）是主要的 IR 成像方式，CT 的使用呈增长趋势（P=0.021）。主要身体区域是血管（45%）和腹部（31%）。3%的摘要中提到了辐射暴露作为一般性陈述，2%的摘要中提到了作为主要主题，1%的摘要中提到了剂量减少。在研究期间，观察到剂量减少摘要的显著增长（P=0.016）。

结论

IR 已成为放射学的一个不断发展的专业领域，教育贡献显著增加。辐射暴露很少成为关注的焦点，但与剂量减少相关的贡献在研究期间呈显著增长。主要结论 • 介入放射学在德国放射学会大会上已成为一个不断发展的专业领域。 • 可以观察到教育和前瞻性研究贡献的显著增加。 • 尽管 CT 呈显著增长趋势，但 IR 的辐射暴露很少成为关注的焦点。 • 在研究期间，与剂量减少相关的贡献呈显著增长。
