What the Record Tells You

Sonumet, the trading name of Laboratorio Nuclear Metropolitano INC, is an NPI registry record for a radiology clinic/centre at T3- #1 Carr 21, Las Lomas in San Juan, Puerto Rico 00921. CMS issued NPI 1336177013 on 29 June 2006, and the organisation last updated its own entry on 8 July 2008. That was 18 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.

San Juan sits in the San Juan-Bayamón-Caguas, PR metropolitan area (San Juan Municipio), which has 244 imaging-centre records on the Puerto Rico side in the September 2026 file, 19 of them with the MRI code, out of 381 across Puerto Rico. The nearest alternatives in the registry are Radiology Imaging CORP. (0.0 miles, San Juan), Metropolitan CT & Open MRI (0.0 miles, San Juan) and Precise Radiology, PSC (1.0 miles, San Juan), with 2 more within 1.3 miles.

For a cash-pay benchmark, our Puerto Rico freestanding-centre estimate is $350 to $900 for a typical single-region MRI. At hospitals our estimate is $1,200 to $3,500; we have not yet read this state's hospital price files. This centre's own prices are not in the registry: call (787) 781-1477 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

Estimated cash price for a single-region MRI in Puerto Rico

Freestanding imaging centre

$350 to $900

Hospital outpatient

$1,200 to $3,500

Lower baseline pricing than mainland US. These ranges are our own estimates for the state, not measured prices and not quotes from any listed centre: no source publishes a per-state MRI cash price. Where we have parsed the hospitals' own price files the real spread is much wider, and those measured figures always appear in place of this panel (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.

Full list: cheap MRI, good MRI checklist.
