Mammography is the most effective method for early detection of breast cancer and yet, 10% to 30% of women who have breast cancer and undergo mammography have negative mammograms. Furthermore, of the women who are sent to biopsy, only 20% to 40% actually have breast cancer. Quantitative analysis of the radiographic features of microcalcifications and masses may help radiologists improve their specificity.
We have now analyzed the use and benefits of four Strategic Thinking Tools for Radiology: the Vision Statement, the High Five, the Two-by-Two, and Real-Win-Worth. Additional tools will be provided during the tutorial. The tools provided above should be considered as examples. They all contain the 10 benefits outlined earlier to varying degrees. It is extremely important that the tools be used in a manner consistent with the Vision Statement of the organization. The specific situation, the effectiveness of the team, and the experience developed with the tools over time will determine the true benefits of the process. It has also been shown that with active use of the types of tools provided above, teams have learned to modify the tools for increased effectiveness and have created additional tools for specific purposes. Once individuals in the organization become committed to improving communication and to using tools/frameworks for solving problems as a team, effectiveness becomes boundless.
According to Peter Ogle of Digital Imaging (San Francisco, CA), "Radiologists should help identify common values for the use of information technology in medicine." Achieving a set of common values often requires a framework for organizing the thought process involved. That is the focus of this article in addressing the subject of picture archiving and communication system (PACS) technology assessment.

Picture archiving and communication systems (PACS) provide image viewing at diagnostic, reporting, consultation, and remote workstations; archival on magnetic or optical media by means of short- or long-term storage devices; communications by means of local or wide area networks or public communication services; and integrated systems with modality interfaces and gateways to health care facilities and departmental information systems. Research indicates three basic needs for image and report management: (a) improved communication and turnaround time between radiologists and other imaging specialists and referring physicians, (b) fast reliable access to both current and previously obtained images and reports, and (c) space-efficient archival support. Although PACS considerations are much more complex than those associated with single modalities, the same basic purchase criteria apply. These criteria include technical leadership, image quality, throughput, life cost (eg, initial cost, maintenance, upgrades, and depreciation), and total service. Because a PACS takes much longer to implement than a single modality, the customer and manufacturer must develop a closer working relationship than has been necessary in the past.
