What the Record Tells You

Midwest Diagnostic Imaging Center is an NPI registry record for a radiology clinic/centre at 4120 Lindell Blvd in Saint Louis, Missouri 63108. CMS issued NPI 1417139023 on 5 December 2007, and the organisation last updated its own entry on 5 December 2007. That was 18 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: Radiology clinic/center (261QR0200X) and Mammography clinic/center (261QR0206X). It registered as a radiology clinic without the MRI-specific code, so ask which modalities it operates before assuming an MRI is available.

Saint Louis sits in the St. Louis, MO-IL metropolitan area (St. Louis city), which has 84 imaging-centre records on the Missouri side in the September 2026 file, 14 of them with the MRI code, out of 211 across Missouri. The nearest alternatives in the registry are Slucare Department of Radiology (1.2 miles, Saint Louis), Bellevue Radiology INC (3.4 miles, Saint Louis) and Watson Imaging Center (4.3 miles, Saint Louis), with 2 more within 5.3 miles.

For a cash-pay benchmark, our Missouri freestanding-centre estimate is $480 to $1,300 for a typical single-region MRI. At Missouri hospitals the cash price is measured rather than estimated: $237 to $2,884 for a brain MRI, median $1,168, from 28 of the 37 Missouri hospitals whose own price files we have read, out of 62 in the state, files dated to July 2026. This centre's own prices are not in the registry: call (866) 504-2674 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 Missouri: 28 hospitals measured

Freestanding imaging centre, estimated

$480 to $1,300

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

Hospital outpatient, measured

$237 to $2,884

Median $1,168 cash against a median gross charge of $2,420, from 28 of the 37 Missouri hospitals whose own price files we have read, out of 62 in the state, files dated to July 2026.

St Louis and Kansas City have competitive independent networks. 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 4 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $10,840; those are kept out of the band above and counted here instead. 5 more hospitals list this code at prices more than three times apart in the same file, from $278 to $2,709, 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.
