Three years' experience with an all-digital nuclear medicine department.

We describe our all-digital, filmless, department of nuclear medicine, which has been fully operational for 3 years. The approach to the design and implementation of a nuclear medicine picture archiving and communication system (PACS) is discussed, as well as enhancements found to be necessary or desirable during our 3 years of experience using the system. Studies are initially viewed on remote monitors in the reading room, and transferred from multiple vendor's computers to the PACS by floppy disc network. Scans are analyzed on networked image workstations using a variety of software imaging tools. Reports are dictated into a digital voice storage system, allowing the referring physician immediate telephone access. The dictated report is typed into a computer, electronically edited, reviewed, billed, and printed for appropriate distribution on an integrated medical information system. The final report is stored on the PACS, along with the scan image and other patient information on 1-gigabyte removable optical discs. Two networked optical disc drives allow us to have approximately 3 years of our department's studies available instantly, allowing recall of previous studies for comparison with the current scan. Emergency night and weekend studies are sent via modern over normal phone lines to the on-call physician, who has a similar image workstation at home. Digital image storage allows for easy manipulation of the data, such as gray scale manipulation and cine (movie) display. Cost analysis shows significant savings compared with a film-based department. We conclude that an all-digital nuclear medicine department is practical, cost effective, and beneficial to both patients and staff.

An all-digital nuclear medicine department.

An all-digital nuclear medicine department is described. Nuclear medicine images are acquired by a separate computer interfaced to each camera. The digital images are viewed, manipulated, and interpreted from remote display stations in an interpretation area. The interpretation is dictated into a Rapid Telephone Access System (RTAS), where the voice is digitized and stored. By dialing the patient's identification number, the referring physician can hear the interpretation over any telephone. The images are filed on large storage discs. The digital scans can be rapidly and easily accessed for later review by the use of several directory programs. This system has brought not only efficiency and cost savings, but the ability for remote viewing elsewhere in the hospital and telephone transmission of nuclear cardiology studies from community hospitals for interpretation in the digital nuclear medicine department.

Telephone transfer of nuclear cardiology studies.

Data of nuclear cardiology studies are acquired on a computer and transmitted by telephone from a community hospital to a computer at a teaching hospital for analysis. Interpretations of the studies are dictated into a RTAS radiology reporting system. The referring physician and transcriptionists from the sending hospital may hear the interpretations by calling into RTAS on the same day as the studies were performed.

The appearances of common dental diseases on radionuclide bone images of the jaws.

Radionuclide images of hospital patients were examined for abnormal areas within the jaws. Fourteen of 25 subjects studied showed one or more abnormal image areas, most of which were attributable to common dental lesions revealed by oral examinations. The lesions detectable on images included healing bone sites, periodontal and pulpal disease, residual osteitis and irritations caused by ill-fitting dentures.

Bone scan in dental diseases.

Bone images of the jaws and related dental structures were obtained in 25 patients undergoing skeletal surveys. The upper and lower jaws were divided into eight quadrants to facilitate comparisons between scintigraphic image findings and the results of dental examination. Fourteen of these 25 patients had at least one jaw quadrant with a positive image. The areas of positive uptake correlated well with dental examination findings, which included healing extraction sites and common dental diseases, such as pulpal and periodontal infections and irritations from ill-fitting dentures. The potential usefulness of bone imaging as an adjunct in dental diagnosis is discussed.
