What the Record Tells You

Omi Diagnostics, the trading name of Diagnostics Imaging Services, is an NPI registry record for a radiology clinic/centre at 6584 Professional Pl, Suite D in Riverdale, Georgia 30274. CMS issued NPI 1548567654 on 25 February 2011, and the organisation last updated its own entry on 25 February 2011. That was 15 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. The same business holds a sibling registration at this address under the name Open MRI Centers of Georgia (NPI 1972507481); they are covered by this page rather than given their own.

Riverdale sits in the Atlanta-Sandy Springs-Roswell, GA metropolitan area (Clayton County), which has 216 imaging-centre records on the Georgia side in the September 2026 file, 16 of them with the MRI code, out of 380 across Georgia. The nearest alternatives in the registry are Radiology Associates of Clayton, P.C. (0.2 miles, Riverdale), South Atlanta Radiology Associates, P.C. (1.3 miles, Riverdale) and Ammed Medical Imaging (1.3 miles, Riverdale), with 1 more within 1.3 miles.

For a cash-pay benchmark, our Georgia freestanding-centre estimate is $480 to $1,300 for a typical single-region MRI. At Georgia hospitals the cash price is measured rather than estimated: $238 to $2,428 for a brain MRI, median $1,212, from 19 of the 47 Georgia hospitals whose own price files we have read, out of 96 in the state, files dated to August 2026. This centre's own prices are not in the registry: call (770) 991-6001 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 Georgia: 19 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

$238 to $2,428

Median $1,212 cash against a median gross charge of $2,789, from 19 of the 47 Georgia hospitals whose own price files we have read, out of 96 in the state, files dated to August 2026.

Atlanta has dozens of independent centres; rural Georgia far less competitive. 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 15 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $11,676; those are kept out of the band above and counted here instead. 9 more hospitals list this code at prices more than three times apart in the same file, from $37 to $1,826, 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.
