Plain radiography, excretion radiography, and contrast radiography
2015Plain radiography is both a primary abdominal examination technique and an initial component of subsequent excretion and contrast radiographic studies. Excretion radiography is performed by means of antegrade opacification of the renal collecting systems, ureters, and bladder following intravenous contrast administration.

The various types of blurring occurring in radiography are examined. Experimental work was carried out by photometering density curves of a sharp edge and the densities were converted to exposures. For the case of screen blurring an exponential function was found to fit experimental results very well.

The painful wrist frequently poses a diagnostic dilemma. Although increased understanding of normal carpal motion has led to more constructive use of roentgenography, the diagnostic acumen of the examiner is greatly enhanced by the standardization of radiographic views as well as by the use of special projections and when indicated, arthrograms.
