What the Record Tells You

Aurion Medical Group LLC is an NPI registry record for a radiology clinic/centre at 190 Groton Rd Ste 130 in Ayer, Massachusetts 01432. CMS issued NPI 1063374700 on 1 December 2025, and the organisation last updated its own entry on 2 August 2026. That is recent, so the contact details are likely current.

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 14 other taxonomy codes (174400000X, 207Q00000X, 207RH0003X, 251F00000X, 261Q00000X, 261QE0002X, 261QH0100X, 261QI0500X, 261QM1300X, 261QM2500X, 261QP2300X, 261QU0200X, 261QX0200X, 261QX0203X).

Ayer sits in the Boston-Cambridge-Newton, MA-NH metropolitan area (Middlesex County), which has 103 imaging-centre records on the Massachusetts side in the August 2026 file, 26 of them with the MRI code, out of 152 across Massachusetts. The nearest alternatives in the registry are Nashoba Radiology Group, LLC (0.8 miles, Ayer), Centmass Imaging, INC. (9.5 miles, Leominster) and Umass Memorial Health Alliance MRI Center LLC (10 miles, Leominster), with 2 more within 11 miles.

For a cash-pay benchmark, our Massachusetts range is $800 to $2,200 at freestanding imaging centres and $2,800 to $7,600 at hospitals for a typical single-region MRI. This centre's own prices are not in the registry: call (617) 785-2066 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

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.

Full list: cheap MRI, good MRI checklist.
