1995 AUR Hartman Centennial Lecture. Academic radiology: time for action.

To summarize, the 10 actions I believe we should take are as follows: 1. Protect our patient base by institutional involvement and selected departmental outreach programs. 2. Reorganize our faculties and gain their support to meet the changes that will occur as a result of health care reengineering. 3. Restructure our residency and fellowship programs to adapt positively to the needs of a new delivery system. 4. Take a stand on resident/fellow training, accreditation issues, and program length and composition. 5. Develop a national program to continue to attract the best medical students into radiology. 6. Get the information needed to provide the best estimate of work force requirements and work toward achieving the proper balance between supply and demand. 7. Support subspecialization in our field. Quality eventually will be an issue. 8. Support research training for faculty and make research important. 9. Continue to present our field as an exciting place to be, which it is. 10. Support the AUR, the SCARD, and the APDR as the collective voice for academic radiology. Finally, I would like to challenge the AUR, the SCARD, and the APDR to unite to become a strong force in academic radiology. Academic radiology now has no singular voice. Radiologists in private practice have the ACR, neuroradiologists have the ASNR, vascular-interventional radiologists have the SCVIR, nuclear medicine radiologists have the Society of Nuclear Medicine, ultrasonographers have the American Institute of Ultrasound in Medicine, and I can name many other important special interest groups within our field. No doubt, all these organizations share many of our common concerns and interests, but having an organization interested solely in the continued health of academic radiology is vital to our future and, because of the reengineering of the health care system, more important than ever. Academic radiology is in the unique position of being radiology's only supplier of human resources and research. We must make our voice heard on staff issues, training program changes, accreditation, certification, financing of graduate education, support for biomedical research, and all other matters important to our academic programs. Although we will be drawn into the delivery of managed care, we cannot afford to ignore our other two principal missions: education and research. If we do, all of radiology will suffer the consequences in years to come. So let's take up the challenge and make our three organizations a steady, consistent, rational but firm voice in the support of academic radiology. I believe that the future of radiology is bright, but we need to make it happen. Now is the time for action. Thank you for the invitation to present the Glen W. Hartman lecture. It is truly a great honor.

Residency and fellowship training in radiology: survey of all United States programs.

RATIONALE AND OBJECTIVES: We surveyed radiology training programs to determine current requirements for a clinical internship year, recent changes in the clinical internship requirement, current number of residents, percentage of residents with preradiology clinical experience, number of current first-year fellows, and percentage of residents entering fellowships. METHODS: Survey forms were sent to all 208 U.S. diagnostic radiology programs and were followed up by telephone and facsimile transmission. RESULTS: Survey response rate was 100%. One hundred programs (48%) require an internship, whereas 108 programs (52%) do not. Of programs without a clinical internship requirement, 33 (31%) have eliminated this requirement within the last 5 years. The clinical year requirement varied greatly by region. A total of 3983 residents are training at present, and 29% did not complete a clinical internship. Currently, 650 fellows are in training. Approximately 68% of graduating residents are entering fellowships. CONCLUSIONS: Many residency programs have recently discontinued the clinical internship year requirement. Changes in Medicare reimbursement of resident salaries may be one factor promoting this change. During the past 4 years, the number of radiology residents training per year has increased. The percentage of residents entering radiology without an internship year has increased by 6% during the past 4 years. An increasing number of graduating residents are entering fellowships.

Picture archiving and communication systems: an overview.

Organizational techniques that enable small departments to function efficiently often fail as departments become larger. With the recent growth in imaging technology, the capacity of film-based systems to meet the increasing needs of radiology departments has decreased. Electronic picture archiving and communication systems (PACS) have been developed in an attempt to provide economical storage, rapid retrieval of images, access to images acquired with multiple modalities, and simultaneous access at multiple sites. Input to a PACS may come from digital or analog sources (when the latter have been digitized). A PACS consists primarily of an image acquisition device (an electronic gateway to the system), data management system (a specialized computer system that controls the flow of information on the network), image storage devices (both short- and long-term archives), transmission network (which serves local or wide areas), display stations (which include a computer, text monitor, image monitors, and a user interface), and devices to produce hard-copy images (currently, a multiformat or laser camera). The goals of PACS are to improve operational efficiency while maintaining or improving diagnostic ability.

Pathways to improved radiologic research. An NIH workshop.

In summary, the workshop recommended two years of research training as being essential for radiologists to acquire the skills and knowledge necessary to begin a successful research career in today's funding and academic environment. Many pathways can combine two years of research training and provide fulfillment of existing requirements to achieve specialty certification and subspecialty credentialing. Departments of radiology supporting the beginning qualified investigator should allow him or her approximately 75% research time for the first three years of the academic appointment. Departmental research time accorded faculty members may best be concentrated on a few individuals, providing them sufficient time to be competitive for peer-reviewed grants and enabling research advances to provide a solid foundation for the future of radiologic imaging.

A computer-assisted radiologic reporting system.

The patient registration and interpretation/reporting modules of a computer-assisted radiologic reporting system are described. Entries may be made at several levels of complexity, using bar codes or keyboard input. Several functions allow convenient access to the database. Output may be reformatted without programmer intervention via a maintenance file. The system allowed improved turnaround time, reduced costs, and better understanding of work patterns.

A comprehensive information service for an academic radiology department.

In order to simplify access to the medical radiology literature, a clinical information service was created within an academic radiology department. The program, administered by a clinical medical librarian, provides literature search services and current literature selection for in-house faculty and staff members to answer questions related to patient management, research, publication, and conference preparation. Additional services are provided through selective bibliographies and "current awareness" searches, both updated frequently, and a monthly journal table-of-contents packet in the areas of radiologic diagnosis/nuclear medicine and radiation therapy. The clinical medical librarian also administers a departmental learning resource center and teaching files. Development of a subscription information service for practicing radiologists is discussed.

A comparison of brain imaging with gamma camera, single-photon emission computed tomography, and transmission computed tomography: concise communication.

We have evaluated the utility of a single-photon axial tomographic scanner (ECT) in brain imaging, using routine tracers in 238 patients. When compared with routine delayed gamma-camera images (DGCI), there was agreement in 191 negative studies and 39 positive studies. Four patients had positive DGCI and negative ECT studies, and four had positive ECT and negative DGCI. In the 102 patients in this series who also had transmission CT (TCT) studies, there were five who had positive emission studies and negative TCT, and 38 with an abnormal TCT and normal ECT. The ECT was occasionally helpful in distinguishing brain and skull metastases, in better portrayal of deep lesions, and in resolving equivocal DGCI findings. For the ECT to become clinically rewarding, however, we feel that it will need development of new tracers that will provide functional information in addition to that already attainable by routine gamma-camera images.

Efficacy of radionuclide scanning in patients with lung cancer.

Ninety-two patients with histologically proved carcinoma of the lung were studied retrospectively to determine the usefulness of liver, brain, and bone imaging in their examination and treatment. Occult metastatic liver disease was observed in two (5.3%) of 38 asymptomatic patients, while four (6.6%) of 58 neurologically intact patients had abnormal brain scans. Eight (13.6%) of 59 asymptomatic patients had metastatic bone disease. Seven (18.4%) of 38 patients with no clinical evidence of metastatic disease to liver, brain, or bone had at least one type of abnormal radionuclide study. More than half (52.5%) of the patients studied had at least one abnormal scan exclusive of symptoms. Radionuclide imaging is a useful procedure in the initial evaluation and subsequent management of lung cancer.
