Clinical Trial Review
Within a month after Roentgen's discovery of the X-ray, the first cadaveric peripheral arteriogram was performed. It was not until 28 years later that the initial in vivo femoral arteriogram was reported. Arteriographic growth and development since that time have been punctuated with such names as Seldinger, Steinberg, Viamonte, Abrams, Sones, and many more. Keeping pace with their technical and diagnostic achievements has been the cause for a whole new industrial field - that of angiographic equipment and technology. New X-ray tubes, generators, film, etc. have been developed. Angiographic tables are available which have been designed to do highly subspecialized studies. The spectrum of catheter curves and materials available allows visualization of vessels down to the order of 0.1 mm when combined with magnification. Chemoangiography for treatment and subselective venous sampling for hormonal assays are commonplace. Although "the beginnings" for all angiography lie in the evaluation of peripheral vasculature, equipment sophistication for this basic study has often lagged behind that of the more glamorous organal examinations. The development of the biphasic ijection technique hopefully represents an anwer to both multiple injections and X-ray exposures. It allows single injection and single exposure visualization of the vascular tree from distal aorta to the pedal vessels.

Systematic classification of roentgen signs according to anatomical and functional alterations is described as follows: Direct roentgen signs of embolism without hemorrhage and without infarction, indirect roentgen signs of embolism without hemorrhage and without infarction, indirect roentgen signs of embolism with hemorrhage, indirect roentgen signs of embolism with infarction, and roentgen signs of microembolism. Diagnostic security of conventional chest films, technique and "timing" of pulmonary angiography, direct and indirect roentgen signs of embolism in pulmonary angiography, and traumatic fat embolism are described.

Comparative Study
STUDY DESIGN
Sagittal plane translatory and rotatory motion was measured in 15 lumbar motion segments of 8 patients by distortion-compensated and stereophotogrammetric Roentgen analysis.
OBJECTIVE
To compare measurement precision of the new distortion-compensated Roentgen analysis protocol with that of the established Roentgen stereophotogrammetric technique under realistic clinical conditions.
SUMMARY OF BACKGROUND DATA
Roentgen stereophotogrammetric analysis constitutes the most precise method available to assess segmental motion. Because of the invasive nature of the procedure, however, there is interest in alternative, noninvasive protocols suitable for studying larger patient cohorts.
METHODS
In 8 patients, segmental motion of 15 lumbar segments that had undergone previous spinal surgery was assessed from stereo views by using Roentgen stereophotogrammetric analysis. Sagittal plane segmental motion was assessed by distortion-compensated Roentgen analysis. Sagittal plane translatory and rotatory motion data obtained by both methods were compared.
RESULTS
With respect to Roentgen stereophotogrammetric analysis, sagittal plane rotation was determined by distortion-compensated Roentgen analysis with an error (standard deviation) of 1.4 degrees and a mean difference of less than 0.05 degree. Sagittal plane translation was determined by distortion-compensated Roentgen analysis, with an error of 1.25 mm and a mean difference 0.5 mm.
CONCLUSION
Measurement precision of distortion-compensated Roentgen analysis is slightly inferior to that of Roentgen stereophotogrammetric analysis but substantially higher than that of conventional protocols assessing lumbar segmental motion. If measurement precision is considered adequate and if a noninvasive technique is indicated, distortion-compensated Roentgen analysis can be used to provide reliable motion data required for epidemiologic and clinical studies.
