What the Record Tells You

St Charles Imaging Center is an NPI registry record for an MRI centre at 558 St Charles Dr, 111 in Thousand Oaks, California 91360. CMS issued NPI 1396097929 on 5 October 2012, and the organisation last updated its own entry on 26 September 2025. That is recent, so the contact details are likely current.

The record carries one imaging taxonomy code: Magnetic Resonance Imaging (MRI) clinic/center (261QM1200X). The MRI-specific code means the organisation registered itself as a magnetic resonance imaging centre, the strongest signal the registry gives that a scanner is on site.

Thousand Oaks sits in the Oxnard-Thousand Oaks-Ventura, CA metropolitan area (Ventura County), which has 27 imaging-centre records on the California side in the September 2026 file, 3 of them with the MRI code, out of 1,513 across California. The nearest alternatives in the registry are Shariar Cohen MD CORP (0.0 miles, Thousand Oaks), Rolling Oaks Radiology Medical CORP Corporation (1.1 miles, Thousand Oaks) and Thousand Oaks Radiology Group (1.4 miles, Thousand Oaks), with 2 more within 1.4 miles.

For a cash-pay benchmark, our California freestanding-centre estimate is $600 to $1,800 for a typical single-region MRI. At California hospitals the cash price is measured rather than estimated: $153 to $8,216 for a brain MRI, median $2,307, from 122 of the 169 California hospitals whose own price files we have read, out of 276 in the state, files dated to September 2026. This centre's own prices are not in the registry: call (805) 230-2700 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 California: 122 hospitals measured

Freestanding imaging centre, estimated

$600 to $1,800

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

Hospital outpatient, measured

$153 to $8,216

Median $2,307 cash against a median gross charge of $5,150, from 122 of the 169 California hospitals whose own price files we have read, out of 276 in the state, files dated to September 2026.

Bay Area and LA imaging centres are competitive; UCSF and Cedars hospitals at the top end. 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 24 hospitals publish a “cash price” that is its chargemaster restated rather than a discount, reaching $20,680; those are kept out of the band above and counted here instead. 12 more hospitals list this code at prices more than three times apart in the same file, from $19 to $1,825, 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.
