It is generally assumed that the radiation risk from mass screening for breast cancer may be neglected. This is questionable in view of the high biological effectiveness of low energy X-rays used in radiography of the breasts. The hormone replacement therapy for elderly women must be considered as a further cause for unexpected high rates of radiation-induced breast cancer cases.

In order to utilize excretory urography for urological diagnosis as optimal as possible renal physiology and pathophysiology as well as urodynamics have to be fully considered. Experimental and clinical data of various degrees of bilateral renal insufficiency, unilateral renal impairment and unilateral hydronephrosis were used to compute plasma and urinary concentrations of contrast media in the diseased and contralateral kidney. The results can be summarized as follows: 1.

Beside the yield of labeled erythrocytes the purity of the suspension of erythrocytes ready for injection from nonerythrocyte activity (NE51Cr) is an important criterion for the quality of the 51Cr-labeling method. After presentation of an especially precise method for measuring the NE51Cr the parameters influencing the NE51Cr in the main were investigated and the NE51Cr was analysed using different methods of separation of its components. ACD was used as anticoagulant.

The number of regional claims was obtained from data on 2408 patients. By the number of regional claims we mean the number of claims for a defined performance in relation to the population living in a certain region; in the present investigation the first claims for in vivo diagnostic thyroid examinations within the administrative area. We found a great reduction of the regional claims in the country administrative areas surrounding Marburg, which was accompanied by a relative increase in advanced disease findings which included some who should have sought medical advice earlier.

In cases of unilateral hydronephrosis the urine concentration of contrast medium, for example diatrizoate, depends on the remaining renal function, the rate of turnover in the obstructed renal pelvis and the function of the contralateral kidney. Contrast medium for a single injection or a short infusion time is rapidly excreted by the normal contraleteral kidney, without allowing high enough plasma levels long enough for sufficient urine concentrations in the hydronephrotic kidney. This excretion rate can be compensated for by continuous infusion urography for several hours with large doses of contrast medium (up to 1,250 ml.
