Magnetic resonance installation: siting and economic considerations.

The authors discuss the economics involved in operating a magnetic resonance (MR) imager in a 600-bed community hospital over a six-month period. Topics considered include patient monitoring; controlling access to the magnet room; depreciation and maintenance; cost of electricity, cryogenic liquids, and personnel; and charges for patient care. Conclusions are made regarding the current use of MR in a community hospital.

An audiovisual program in cell biology.

Cell biology has been divided into 19 topics for the purpose of planning audiovisual materials. One of these topics, the structure and function of cell membranes, has been developed as a series of seven self-instructional slide-tape units and tested in five medical schools. Organization of advisers, analysis and definition of objectives and content, and development and evaluation of scripts and storyboards are discussed.
