What the Record Tells You
Centrelake Medical Group, INC. is an NPI registry record for an MRI centre at 3115 E Guasti Rd in Ontario, California 91761. CMS issued NPI 1639137938 on 3 May 2006, and the organisation last updated its own entry on 24 May 2021. That was 5 years ago, so treat the phone number and suite as unverified until you have spoken to someone there.
The record carries 2 imaging taxonomy codes: Diagnostic radiology (physician specialty code carried by an organisation) (2085R0202X) and 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. It also holds one other taxonomy code (261QX0203X).
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 Ultrasound Institute Medical Group (0.8 miles, Ontario), Inland Diagnostic Imaging (1.3 miles, Rancho Cucamonga) and Renaissance Radiology Medical Group, INC. (2.2 miles, Rancho Cucamonga), with 2 more within 2.8 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) 635-0411 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
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.
