Imaging Centers in Washington: 196 MRI and Radiology Centre Records
The September 2026 NPI file lists 196 imaging organisations in Washington: 89 registered under the MRI or radiology clinic codes (31, or 16%, with the MRI-specific code) and 107 diagnostic-radiology organisations classified by name. Seattle-Tacoma-Bellevue is the largest market with 106 records, followed by Spokane-Spokane Valley (17), Kennewick-Richland (12) and Mount Vernon-Anacortes (9). 5 records sit outside the metro areas listed below or alone in a small area; they are listed on this page.
Price context: a single-region MRI in Washington runs $700 to $1,900 cash at a freestanding centre, which is our own estimate. At hospitals it is measured, not estimated: a brain MRI runs $539 to $3,078 cash, median $1,362 against a median gross charge of $2,730, from 32 of the 35 Washington hospitals whose own price files we have read, out of 46 in the state, files dated to August 2026. A further 1 hospital publishes their chargemaster unchanged as a “cash price”, up to $2,720, and are not in that range. Seattle market competitive but academic centres (UW, Virginia Mason) at the top.
