Functional requirements for a HIS-RIS-PACS-interface design, including integration of "old" modalities.

Radiology, Information Systems (RIS) and Picture Archiving Systems (PACS), have the potential for immense rationalization of operations in radiology and hence for the improvement of health care, as well as the return of investments. These systems must, however, be carefully designed such that they support routine work rather than being an additional burden to radiology staff. Analyses show that comprehensive communication of patient demographic and clinical data between RIS, PACS and Hospital Information Systems (HIS) are necessary prerequisites to achieve cost effectiveness.

Usefulness of morphological characteristics for the differentiation of benign from malignant solitary pulmonary lesions using HRCT.

The aim of this study was to analyze different characteristics on high-resolution computed tomography (HRCT) that help differentiate benign solitary pulmonary lesions (BSPLs) from malignant solitary pulmonary lesions (MSPLs). High-resolution computed tomography was performed on 104 consecutive patients with SPLs. The whole lesion was examined with a slice thickness of 1 mm and a 12-cm field of view.

[The filmless hospital--a legal challenge].

Purpose: This article concerns the legal aspects of digital archiving of radiological images, in particular with regard to the resolution passed by the 37th Committee meeting of the Federal Board of "RöV" (x-ray ordinance). Concepts of filmless hospitals must therefore be tested for compliance with all present legal requirements.

Material And Methods: The literature concerning the legal aspects of digital medical archiving of x-ray documents is reviewed.

[A comparison of the monitor and alternator findings of digital thoracic images with the aid of a computer-supported procedure].

Purpose: To compare softcopy and hardcopy reading of chest radiographs a software tool was designed for creating lesions with clearly defined size, location and contrast.

Method: An ROC study was performed using a set of chest radiographs with 300 simulated small nodules and linear details displayed on film and on a 1 K monitor. Six observers participated in the study.
