The UW AIRP serves as a core ultrasound laboratory for clinical and epidemiological research studies using measurement of carotid intima-media thickness and/or brachial artery reactivity as cardiovascular outcomes. Core lab services include sonographer and reader training, image interpretation and quantitation, data analysis, quality assurance, protocol design, and consultation.
For local studies, the UW AIRP performs, acquires, and stores all ultrasound data in digital formats without the use of videotape, using high-end Siemens Acuson ultrasound systems with high-resolution linear array ultrasound transducers. Images are stored in DICOM using vendor-provided software or as digitized video streams using an Emageon Vericis system.
For local and multicenter studies, images are stored on a secure server. Duplicate digital images are stored on mirrored hard drives or hard digital media with digital tape archiving.
The UW AIRP uses validated, proprietary software programs to read and interpret studies. The lab is capable of reading any DICOM compatible image and most other digital image formats. Images can be sent to the UW AIRP using a secure ftp server, direct network connection, or on any digital media. The UW AIRP also can digitize studies originally stored on super-VHS videotape. We have a site network database with collaborating centers available for use in the development of clinical trials.
Appropriate quality assurance parameters are built into every protocol and include phantom scanning, determination of test-retest reproducibility, and intra- and inter-observer variability. The UW AIRP data regarding these parameters can be provided upon request and are detailed in our publications.
