Eine SWOT (Stärken, Schwächen, Chancen und Gefahren)-Analyse der aktuellen digitalen Radiografiesysteme in der Thorax- und Skelettdiagnostik

Zusammenfassung

Zielsetzung: Ziel war eine Evaluierung der Stärken und Schwächen und der damit verbundenen Chancen und Gefahren, auch SWOT-Analyse, der aktuellen digitalen Radiografiesysteme. Damit soll Radiologen für die Anschaffung eines Radiografiesystems eine Hilfestellung zur Entscheidungsfindung zur Seite gestellt werden. Methodik: Die aktuell auf dem Markt befindlichen Technologien für die Speicherfolienradiografie (CR) und Direktradiografie (DR) wurden einer systematischen Analyse unterzogen. Dazu wurden sie hinsichtlich der physikalischen Leistungsmerkmale, der diagnostischen Genauigkeit, dem Potenzial zur Strahlendosisreduktion und ökonomischen Parameter evaluiert und in SWOT-Tabellen gegenübergestellt. Ergebnisse: Die physikalischen Leistungsparameter und die diagnostische Genauigkeit zeigen einen klaren Vorteil für DR-Systeme mittels TFT (thin-film transistor) gegenüber Speicherfolien. Nadelkristalldetektoren sind eine wichtige Weiterentwicklung der CR-Systeme, da sie hinsichtlich der physikalischen Parameter mit DR-Systemen vergleichbar sind. Speicherfoliensysteme stellen durch niedrige Anschaffungskosten, leichte Integrierbarkeit in bestehende Filmfolien-Systeme und einfache Durchführung von Untersuchungen in der Intensiv- und Notfallradiografie eine potenzielle Alternative dar. Zudem haben technologische Entwicklungen wie dual-side reading und ScanHead zu einer höheren Konkurrenzfähigkeit von CR-Systemen gesorgt. Schlussfolgerung: Die Frage nach dem am besten geeigneten digitalen Radiografiesystem hängt entscheidend von den gestellten Anforderungen und dem Einsatzgebiet ab und lässt sich nicht einfach und klar beantworten. Anhand der beschriebenen Stärken und Schwächen der digitalen Radiografiesysteme kann der Radiologe kaufmännisch analysieren, welche Chancen und Gefahren auf die Geschäftseinheit zukommen können.

Abstract

Purpose: To evaluate the strengths, weaknesses, opportunities and threats (SWOT analysis) of the current digital radiography systems for thorax- and skeletal diagnostics. To provide assistance for radiologists, who have to decide on the acquisition of a radiography system. Materials and Methods: The computed radiography (CR) and direct radiography (DR) technologies which are commercially available were evaluated systematically regarding their physical characteristics, diagnostic accuracy, potential for dose reduction and economic parameters. These facts were presented in SWOT tables. Results: The physical parameters and diagnostic accuracy show a clear advantage for DR systems using TFT (thin film transistor) over storage-phosphor image plates (IP). These advantages enable the potential for dose reduction too. Needle-structured IP represent an important development of CR systems. They are comparable with DR-systems using TFT regarding the physical parameters. CR-systems represent a potential alternative, due to their low costs of acquisition, the possibility for easy integration into existing film-screen systems, and their simple handling in intensive care and emergency radiography. Technological developments like dual-side reading and ScanHead improved the competitiveness of CR systems. Conclusion: Which digital radiography system might be best suited for specific site depends crucially on the requirements posed and the operational area. The answer to this question is not simple. On basis of the strengths and weaknesses of the digital radiography systems, the radiologist is able to analyze the opportunities and threats for the business unit.
