What the Record Tells You

United Medical Imaging P.A., the trading name of Mai Spine Center P.A., is an NPI registry record for an MRI centre at 485 Arundel St # 102 in Saint Paul, Minnesota 55103. CMS issued NPI 1285050211 on 14 March 2014, and the organisation last updated its own entry on 14 March 2014. That was 12 years ago, so treat the phone number and suite as unverified until you have spoken to someone there.

The record carries one imaging taxonomy code: Magnetic Resonance Imaging (MRI) clinic/center (261QM1200X). The MRI-specific code means the organisation registered itself as a magnetic resonance imaging centre, the strongest signal the registry gives that a scanner is on site. The same business holds a sibling registration at this address under the name Spine and Joint Imaging Center (NPI 1487104683); they are covered by this page rather than given their own.

Saint Paul sits in the Minneapolis-St. Paul-Bloomington, MN-WI metropolitan area (Ramsey County), which has 74 imaging-centre records on the Minnesota side in the September 2026 file, 28 of them with the MRI code, out of 97 across Minnesota. The nearest alternatives in the registry are Northstar Radiology PLLC (0.0 miles, Saint Paul), Elite Radiology P.A. (0.0 miles, Saint Paul) and Midwest Radiology Outpatient Imaging, LLC (1.0 miles, Saint Paul), with 1 more within 1.5 miles.

For a cash-pay benchmark, our Minnesota freestanding-centre estimate is $550 to $1,500 for a typical single-region MRI. At Minnesota hospitals the cash price is measured rather than estimated: $232 to $4,120 for a brain MRI, median $1,281, from 35 of the 38 Minnesota hospitals whose own price files we have read, out of 45 in the state, files dated to August 2026. This centre's own prices are not in the registry: call (651) 797-3866 with the CPT code for your scan and ask for the self-pay rate, whether the radiologist's report is included, and the scanner's field strength.

Cash-Price Benchmark

Cash price for a brain MRI in Minnesota: 35 hospitals measured

Freestanding imaging centre, estimated

$550 to $1,500

Our own estimate. No imaging operator publishes a per-state cash price.

Hospital outpatient, measured

$232 to $4,120

Median $1,281 cash against a median gross charge of $2,475, from 35 of the 38 Minnesota hospitals whose own price files we have read, out of 45 in the state, files dated to August 2026.

Mayo Clinic premium; Twin Cities competitive otherwise. The hospital figures are CPT 70551, brain MRI without contrast, taken from each hospital's own federal transparency file and attributed to the date that file carries. 2 more hospitals list this code at prices more than three times apart in the same file, from $118 to $524, so which row is the scan cannot be told from the file; they are excluded from the band and counted here. Hospitals whose file we could not read are named, not filled in (methodology).

What to ask when you call

The self-pay price for your exact CPT code (70551 brain, 72148 lumbar spine, 73221 or 73721 joint, without contrast), and whether the radiologist's report is included.
Scanner field strength (1.5T or 3T) and whether it is closed, wide-bore or open.
ACR or IAC accreditation, and who reads the images. The registry cannot tell you either.
Whether they accept an order from a telehealth referral if you have no local doctor.
