Observer variation in skeletal radiology

Skeletal Radiology, 1983
The factors that affect observer variation in bone radiology are analysed from data in the literature and on the basis of studies carried out at McMaster University on the hands and sacroiliac joints. A plea is made for presenting results in terms of Kappa statistics so that agreement due purely to chance is eliminated.

Observer variation in assessing renal scarring

The British Journal of Radiology, 1980
To examine the extent of variation between experienced observers in recognizing renal scarring, 60 intravenous urograms from schoolgirls with bacteriuria were presented separately to three radiologists with a major interest in the radiology of the urinary tract.

Observer variation in equine abdominal auscultation

Equine Veterinary Journal, 1990
Summary The reliability of abdominal auscultation was investigated via an observer variation study. Clinicians listened to a variety of minute‐long equine gut sound recordings. They evaluated the amount of gut sounds as ‘absent’, ‘decreased’, ‘normal’, or ‘increased’.

Intra‐observer and inter‐observer variation of Hertel exophthalmometry

Ophthalmic and Physiological Optics, 2009
AbstractPurpose:  This study investigated the intra‐observer and inter‐observer variation of Hertel exophthalmometry.Methods:  Seventy normal Chinese adults had bilateral exophthalmometry performed by two examiners. The two examiners were masked to the measurement results.

Inter-observer and intra-observer variation in bone histomorphometry

Calcified Tissue International, 1986
Inter-observer variation has been examined for a number of histomorphometric indices in 20 normal human iliac crest biopsies. Quantitation was performed using an eye-piece graticule and eye-piece micrometer. The same sections were examined by two observers and the methodology was identical. Intra-observer variation was also assessed.

Laser Resurfacing: Observations and Variations

International Journal of Cosmetic Surgery and Aesthetic Dermatology, 2000
Laser resurfacing has become increasingly popular among cosmetic surgeons and the public during the last decade. Numerous brands and types of lasers are available. Countless choices of postsurgical wound care methods and mechanisms are available. New technology and variable practice patterns have resulted in less standardized care.

Observations of Irradiance Variations

Space Science Reviews, 2000
Since November 1978 a complete set of total solar irradiance (TSI) measurements from space is available, yielding a time series of 21 years. From measurements made by different space radiometers (HF on NIMBUS-7, ACRIM I on SMM, ACRIM II on UARS and VIRGO on SOHO) a composite record of TSI can be compiled.

Observations of regional strain variations

Journal of Geophysical Research, 1972
An array of six strainmeters was used to determine a least-squares regional strain field in southern Nevada. The deformation occurs in several distinct episodes over the 8-month interval analyzed. In each episode the directions of principal axes remain NW and NE, and the deformation is almost entirely pure shear. The end of each episode is marked by an

Comments on the observability of coronal variations

Solar Physics, 1988
The observable variability of spectral lines in the soft X-ray and XUV region is discussed. Rapid variability of coronal emission, both in flaring and non-flaring structures, has been reported and is particularly prominent when high spatial resolution is available.

Observer variation in the detection of osteopenia

Skeletal Radiology, 1986
In order to determine observer variation in the detection of osteopenia, 15 pairs of lateral chest radiographs obtained within two weeks of each other were reviewed separately by two radiologists and one orthopedist on three separate occasions. Intra- and interobserver variations were calculated for each individual film and film pairs using Kappa ...
