Consequences appear for radiologists, but no less for clinicians, health officials and financing. The radiologist gives advice to the clinician on the selection of investigation and technique and the demonstration of the results. For this he needs clinical information. Todays radiology should be organized as an centralized service. Splitting into fields or disciplines is inefficient. Financial bodies must recognize the high costs also for maintainance. The only way for cost reduction is central installation and multi-shift employment. Financing must provide the money for manpower and materials. The reduction of unnecessary radiologic investigations can be achieved by radiologists only with the help of economists. Modern diagnostic radiology has a central role in the health services. The pretentiousness of clinicians, the effectiveness of the administration and economy can be seen in their relation to diagnostics as a whole and especially diagnostic radiology.

Since then, our interest was focused on the hypertensive heart, earlier under the aspect of early discovering and influencing heart insufficiency, later concerning a developing myocardial ischemia, in relationship to left ventricular hypertrophy. At the Charité more than 1,000 microcatheterizations in more than 400 hypertensive cases have been performed, mostly in combination with nuclear-cardiological measurements. The rate of complications was found minimal. Thus, cardiac function could be characterized hemodynamically, at rest and even under ergometric load. Special programmes served the acute application of drugs for diagnostic or therapeutic reasons.
