Zusammenfassung
Eine sichere und einfache szintigraphische Technik der Diagnose des primären Sjögren-Syndroms wird erläutert, die eine relativ hohe Spezifität und Sensitivität erbringt. Bisher wurde mit brauchbarem Erfolg die Serienszintigraphie eingesetzt; die hier beschriebene Verwendung des Linearitäts-Index erbrachte jedoch bessere Ergebnisse. Bei 71 untersuchten Patienten wurde eine Sensitivität von 87% und eine Spezifität von 93% ermittelt. Somit ist dies die Methode der Wahl zur Bewertung von Patienten mit Verdacht auf primäres Sjögren-Syndrom.
Summary
A safe and simple technique is reported by which primary Sjogren’s syndrome can be detected with a relatively high specificity and sensitivity. The method of serial scintigraphy has been used with reasonable success; however, the application of the linearity index as described here produced superior results. In 71 patients investigated, a sensitivity of 87% and specificity of 93% were recorded and make this the method of choice for evaluating patients suspected of having primary Sjogren’s syndrome.
