[Teleradiology with personal computers].

A system to transmit radiographic images with the aid of a personal computer (PC) via phone line is presented. The pictures are recorded by a camcorder and digitized by the PC. They are sent to the receiver by a modem via phone line. The different steps can be programmed. MR and CT pictures as well as ordinary x-ray pictures have been transmitted. It takes about 45 s to send a picture. It arrives in good quality, and findings are clearly represented. After the sending process is completed, all pictures can be reviewed in seconds. The presented system is interesting for its low price when a PC is available.

[Importance of intravenous digital subtraction angiography in the diagnosis of aneurysms in the region of the abdominal aorta].

The arterial vessels can be examined with satisfactory relevance via intravenous DSA using a relatively small amount of contrast medium. An aneurysm first diagnosed via sonography in the region of the abdominal aorta was confirmed in this manner in 19 patients. In 7 of these cases, it was also possible to diagnose a stenosis in the renal artery region. This method can supply exact information on the size, position and extension of the aneurysm--since the equipment has been technically improved--even in the case of kinking of the vessels. It can also supply information in the relationship of the aneurysm to visceral arteries, on the degree of calcification of the vessel walls, and on the additional occurrence of vascular stenoses. Hence, we are of the opinion that intravenous DSA is the method of choice after sonography has been performed and that it is superior to CT within the framework of preoperative examinations of aneurysms of the abdominal aorta.

[Digital subtraction angiography with dynamic color function images].

The authors present for the first time the principles and initial results of a laboratory pilot plant with which parametric colour images can be produced in real time. These images are digital function images of the type originally made widely known by Höhne et al. The colour function images can be produced during conventional digital subtraction angiography (DSA) practically as a sideline, that is to say, with a minimum of time and effort, as a parallel product. Despite the fact that the course of the functional processes can be visualised dynamically, the only feature required is the storage capacity of a single digital TV screen image. Of course, the colour function image is not a substitute for exact quantitative evaluations. However, it does furnish a rapid survey of haemodynamic processes for a multitude of patients in routine diagnosis.
