Computed tomography (CT) examinations in Switzerland significantly increased between 1998 and 2004. This study highlights the growing use of CT scans and aims to optimize their application.

Area of Science:

  • Radiology
  • Medical Imaging
  • Public Health

Background:

  • Computed tomography (CT) is a crucial diagnostic imaging modality.
  • Understanding the trends in CT utilization is essential for healthcare planning and resource allocation.

Purpose of the Study:

  • To analyze the frequency and progression of CT examinations in Switzerland.
  • To identify descriptive variables influencing CT utilization patterns.

Main Methods:

  • Data collected from administrative records, a nationwide inquiry, and Swiss university hospitals.
  • Analysis of CT examination frequency in 1998 and trends over time.
  • Inclusion of data from both hospitals and private radiology practices.

Main Results:

  • CT scanner numbers rose by 7% from 1998 to 2004.
  • In 1998, CT examinations averaged 46.3 per 1000 population.
  • Skull CTs were most common (24%); spine CTs were more frequent in private practices. Pediatric CTs stabilized at 5%.

Conclusions:

  • A significant increase in CT examinations was observed in Switzerland.
  • The study aims to raise physician awareness regarding CT utilization for optimization.
  • Further research may explore factors driving these trends and their clinical implications.
