Gray-scale sonographic spectrum of hypernephromas.

The sonographic appearances of 43 proved hypernephromas was characterized and correlated with the angiographic and pathologic features. This report details the findings and emphasizes the criteria for recognizing poorly echogenic tumors, which may be confused with cysts. A diagnostic dilemma may be posed by these tumors, particularly if angiography shows no evidence of tumor neovascularity. The end point in diagnostic work-up of these tumors must be based upon a correlative approach utilizing the clinical, urographic, sonographic, and angiographic data.

Comprehensive analysis of a Radiology Operations Management computer system.

The Radiology Operations Management computer system at the Hospital of the University of Pennsylvania is discussed. The scheduling and file room modules are based on the system at Massachusetts General Hospital. Patient delays are indicated by the patient tracking module. A reporting module allows CRT/keyboard entry by transcriptionists, entry of standard reports by radiologists using bar code labels, and entry by radiologists using a specialty designed diagnostic reporting terminal. Time-flow analyses demonstrate a significant improvement in scheduling, patient waiting, retrieval of radiographs, and report delivery. Recovery of previously lost billing contributes to the proved cost effectiveness of this system.

Radiology management: the advantages of the dedicated mini-computer.

When planning to automate management functions, a department must choose between using a dedicated mini-computer and the hospital's large central computer facility. Rapid response times and ease of program modification are important advantages of the dedicated mini-computer; moreover, limitations on transmission speeds and the variety of terminals available are disadvantages of the central computer facility. The substantial reduction in the cost of computers coupled with the availability of well designed data-base management systems which allow communication with other systems are additional reasons for selecting the mini-computer. In selecting systems that are already programmed, the department minimizes risks and implementation difficulties.

Design of a medical image management system: a practical cost-effective approach.

The impact of technology and economics is driving radiology departments into a digital era. There have been significant developments in the design of Medical Image Management System components. However, many important design criteria have been neglected, leading to an ineffective end product. This paper will discuss the more important design criteria. The design will be considered from the user's point of view. The implementation of a prototype Medical Image Management System (MIMS) serving a Medical Intensive Care Unit in our Institution will be presented. The structure and very preliminary results of a clinical evaluation will be discussed. Plans to expand the MIMS beyond the Department and the Hospital will also be briefly discussed. The role of the personal computer in the design of a MIMS will be reviewed.

Clinical experience with PACS at the University of Pennsylvania.

A Picture Archiving and Communication System (PACS) was installed in the Medical Intensive Care Unit of the Hospital of the University of Pennsylvania. For one year, 8 week periods of FILM ONLY usage were alternated with 8 week periods of PACS OR FILM usage. The time interval between obtaining portable chest images and taking image dependent actions decreased when the PACS was used, however, about 40% of the action decisions were made without a radiologist's consultation. Only 5% of action decisions were made without consultation during the FILM ONLY periods. A new clinical study for measuring diagnostic accuracy and efficiency as well as communication patterns is described.

Multimedia in the radiology environment: current concept.

Multimedia has different meanings according to its context. Here, multimedia in the radiology environment is defined as the integration of multiple radiology and medical information systems to facilitate the practice of radiology. These information systems include the hospital information system, radiology information system, picture archiving and communication systems, voice reporting, library information systems, and electronic mail and file systems. The concept of multimedia within the context of integration of these database systems will be presented. An example is given on how to access these information systems by a radiologist's desktop personal computer.

Costs and benefits of picture archiving and communication systems.

A picture archiving and communication system (PACS) is an electronic and ideally filmless information system for acquiring, sorting, transporting, storing, and electronically displaying medical images. PACS have developed rapidly and are in operation in a number of hospitals. Before widespread adoption of PACSs can occur, however, their cost-effectiveness must be proven. This article introduces the basic components of a PACS. The current PACS cost-analysis literature is reviewed. Some authors conclude that the PACS would pay for itself, while others find the PACS much more expensive. Explanations for these differences are explored. Almost all of these studies focus on direct costs and ignore indirect costs and benefits. The literature characterizing the indirect costs of PACS is reviewed. The authors conclude that there is a need for uniform, well-defined criteria for the calculation of the costs and savings of PACSs.
