PURPOSE: To transmit DICOM data to a personal computer in the hospital without PACS, and estimate theusefulness of digital image management and its convenience for physicians through transmitted file size,transmission time and quality of transmitted images. MATERIALS AND METHODS: The raw data of three brain MRI andlumbar spine MRI were transmitted from an MR system to a personal computer via Ethernet TCP/IP connection. Thefile size and transmission time of transmitted images were measured according to the matrix number. Threeboard-certified radiologists compared the image quality of the transmitted and scanned images. RESULTS: Thetransmission of DICOM data to the personal computer was successful and the transmitted images and their headerinformation were displayed by various personal computer-based DICOM viewing programs. The file size andtransmission time of the 256 and 512 matrix images were 136 Kbyte, 2.17 seconds/slice and 520 Kbyte, 4.37seconds/slice, respectively. All radiologists regarded the transmitted brain MRI images as superior. Oneradiologist considered the transmitted lumbar spine MRI images superior, while others decided that the quality oftransmitted and scanned images was the same. CONCLUSION: The transmission of DICOM format image data to apersonal computer through an appropriate DICOM receiving program is useful for managing digital images andconvenient for physicians in the hospital without PACS.
