What the Record Tells You

Ultrasound Institute Medical Group is an NPI registry record for a radiology clinic/centre at 3700 Inland Empire Blvd, Suite 250 in Ontario, California 91764. CMS issued NPI 1346658556 on 31 July 2014, and the organisation last updated its own entry on 31 July 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: Radiology clinic/center (261QR0200X). It registered as a radiology clinic without the MRI-specific code, so ask which modalities it operates before assuming an MRI is available. It also holds 5 other taxonomy codes (246XC2903X, 246XS1301X, 247100000X, 2471S1302X, 2471V0105X).

Ontario sits in the Riverside-San Bernardino-Ontario, CA metropolitan area (San Bernardino County), which has 153 imaging-centre records on the California side in the August 2026 file, 21 of them with the MRI code, out of 1,312 across California. The nearest alternatives in the registry are Centrelake Medical Group, INC. (0.8 miles, Ontario), Inland Diagnostic Imaging (1.0 miles, Rancho Cucamonga) and Renaissance Radiology Medical Group, INC. (2.0 miles, Rancho Cucamonga), with 2 more within 2.4 miles.

For a cash-pay benchmark, our California range is $600 to $1,800 at freestanding imaging centres and $2,200 to $7,500 at hospitals for a typical single-region MRI. This centre's own prices are not in the registry: call (909) 483-5550 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.

What to ask when you call

  1. 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.
  2. Scanner field strength (1.5T or 3T) and whether it is closed, wide-bore or open.
  3. ACR or IAC accreditation, and who reads the images. The registry cannot tell you either.
  4. Whether they accept an order from a telehealth referral if you have no local doctor.

Full list: cheap MRI, good MRI checklist.
