Diagnostic disagreement of imaging quantitative sonography of the calcaneus with dual X-ray absorptiometry of the spine and femur.
OBJECTIVE: This study evaluates the diagnostic agreement between imaging quantitative sonography of the calcaneus and dual X-ray absorptiometry of the spine and femur for diagnosing osteoporosis. MATERIALS AND METHODS: In 498 female patients (56 +/- 18 years old), bone mineral density measurements by dual X-ray absorptiometry of the lumbar spine (posteroanterior, L1--L4) and the proximal femur and imaging quantitative sonography of the calcaneus were performed. The percentage of patients having T-scores less than or equal to a threshold of -2.5 standard deviations below a young normal reference was used to compare quantitative sonography with dual X-ray absorptiometry. The diagnostic agreement was assessed using kappa scores. RESULTS: Approximately 30% of the patients had a T-score less than or equal to -2.5 standard deviations as assessed by imaging quantitative sonography (broadband ultrasound attenuation), 26.5% as assessed by dual X-ray absorptiometry of the spine, and 16.7--56.4% as assessed by dual X-ray absorptiometry of the different regions of interest at the femur. Kappa analysis showed that severe diagnostic disagreement exists among broadband ultrasound attenuation and dual X-ray absorptiometry (kappa = 0.28-0.42). CONCLUSION: Considerable diagnostic disagreement exists between imaging quantitative sonography and dual X-ray absorptiometry of the spine and femur. The disagreement is in the same range as that reported recently in comparisons of dual X-ray absorptiometry and nonimaging quantitative sonography. In general, no distinct advantage for imaging quantitative sonography could be found when compared with other techniques.

Peripheral quantitative CT of the forearm: scanner cross-calibration using patient data.
Bone density measurements by peripheral quantitative CT (pQCT) of the distal radius in 87 women (age 38.4 +/- 12.3 years) were obtained on a both a Stratec XCT 900 and an updated version XCT 1400. Axial area, and total and trabecular bone mineral density (BMD) results from both scanners were compared for all patients using linear regression analysis. To achieve scanner calibration we used the intercept and slope of the patients' correlations. The correlations of the patients' values were good for area (r = 0.83) as well as total BMD (r = 0.90) and excellent for trabecular BMD (r = 0.97). The cross-calibration approach in our study provided compatibility of pQCT for trabecular and total ROIs, the clinically mostly utilized volumes of measurement.

[The civil law liability in radiology. An analysis of the administration of justice].
This study comprises 76 published judgments by German and Austrian civil courts between 1966 and 1993 concerning liability in the field of radiology. There has been a marked increase in the number of legal proceedings in the 1980's and even more so in the second half of this decade. This is due to an increased tendency to sue doctors without any legal cause in the hope of possible compensation. In 40.8% of the cases the doctor was held liable and required to compensate the patient for personal injury and suffering pain. Most of the cases were related to complications during the examination procedure. The reason most frequently cited by the courts for sentencing doctors was the fact that they did not previously inform the patient adequately about the examination and its possible consequences.
