Materials and methods: Sixty-seven normal adult volunteers underwent ultrasound examination of each eye by three independent observers using a 7 MHz sector probe. Three measurements were made of each eye by each observer and a mean value calculated for each eye. Median and 5th–95th centile values for both intra- and inter-observer variation were calculated for the three observers. Results: The median intra-observer variation was ±0.1 mm, with 5th–95th centile values of ±0–0.4 mm. The median inter-observer variation was ±0.2–0.3 mm, with 5th–95th centile values of ±0–0.7 mm. Careful review of examination technique by the three observers after the first 17 examinations was shown to reduce both intra- and inter-observer variation. Conclusion: The sonographic measurement of ONSD is a readily learned, reproducible technique with low intra- and inter-observer variation. The average inter-observer variation (±0.2 mm) is comparable to the inherent variability of the ultrasound machine. The importance of standardisation of examination technique is stressed.</div>","PeriodicalId":79592,"journal":{"name":"European journal of ultrasound : official journal of the European Federation of Societies for Ultrasound in Medicine and Biology","volume":"15 3","pages":"Pages 145-149"},"PeriodicalIF":0.0,"publicationDate":"2002-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0929-8266(02)00036-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"22104635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We assessed 320 vessels in total, bilateral internal carotid arteries, vertebral arteries, M1 segments of middle cerebral arteries (MCAs), and P2 segments of posterior cerebral arteries (PCAs). Out of all vessels, 250 (78.1%) could be evaluated by neurosonography because 32 MCAs and 38 PCAs were excluded due to inadequate acoustic windows for TCCS. Significant occlusive lesions (>50%) were observed in 21 out of 250 vessels by neurosonography. Angiography confirmed 20 occlusive lesions as revealed by neurosonography. In the remaining 229 neurosonographically normal vessels, angiography showed no significant lesions except M2 occlusions. The accuracy, sensitivity, and specificity of neurosonography for the detection of occlusive vessels were 99.6, 100 and 99.6%, respectively. Occlusive lesions were observed in 20 of all patients by neurosonography. Nineteen of them were confirmed by angiography.

Fifteen consecutive patients (age 14–52 years) underwent complete ophthalmological examination. UBM was performed at a sound frequency of 50 MHz on 17 eyes of 10 patients to determine the extent of disease.

There was no significant difference in the grading of pars planitis by indirect ophthalmoscopy as compared to grading by UBM (P>0.05).

Simple test objects are used which have a long life expectancy. The tests performed both in fundamental and in (tissue) harmonic modes when applicable are spatial resolution, contrast sensitivity, and clutter. The concept of a computational observer is used to define the lesion signal-to-noise ratio and the tissue-to-clutter ratio. Further imaging performance features are penetration depth, slice thickness and geometric conformity of display. Pulsed Doppler velocity measurement features tested are: sensitivity, depth and 3D size of the sample volume, velocity measurement, channel separation.
