What the Record Tells You

Chisholm Trial Imaging LLC is an NPI registry record for a radiology clinic/centre at 1509 Brookwood Ave, Suite B in Duncan, Oklahoma 73533. CMS issued NPI 1801946009 on 11 January 2007, and the organisation last updated its own entry on 22 August 2020. That was 6 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.

Duncan sits in the Duncan, OK micropolitan area (Stephens County), which has 3 imaging-centre records on the Oklahoma side in the September 2026 file, 0 of them with the MRI code, out of 177 across Oklahoma. The nearest alternatives in the registry are Radiologic Services of Oklahoma PLLC (6.5 miles, Duncan), Drh Imaging, LLC (6.5 miles, Duncan) and The Lawton Imaging Center, LLC (25 miles, Lawton), with 2 more within 27 miles.

For a cash-pay benchmark, our Oklahoma freestanding-centre estimate is $450 to $1,200 for a typical single-region MRI. At Oklahoma hospitals the cash price is measured rather than estimated: $493 to $8,887 for a brain MRI, median $1,361, from 16 of the 27 Oklahoma hospitals whose own price files we have read, out of 76 in the state, files dated to August 2026. This centre's own prices are not in the registry: call (580) 252-0553 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 Oklahoma: 16 hospitals measured

Freestanding imaging centre, estimated

$450 to $1,200

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

Hospital outpatient, measured

$493 to $8,887

Median $1,361 cash against a median gross charge of $1,930, from 16 of the 27 Oklahoma hospitals whose own price files we have read, out of 76 in the state, files dated to August 2026.

Oklahoma City Surgery Center pioneered transparent pricing. 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. A further 2 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $1,670; those are kept out of the band above and counted here instead. 2 more hospitals list this code at prices more than three times apart in the same file, from $54 to $469, 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.
