Ultrasound Interpretation · Maternal-Fetal Medicine

The ultrasound experts, reading your scans.

Obstetric ultrasound is the single imaging modality MFM physicians train longest to master. Ouma puts that expertise behind your scans, reading remotely for OB practices, MFM groups, mobile-ultrasound companies, and midwives nationwide. You get higher diagnostic quality, less liability for the referring provider, and access to reimbursement you may not be capturing today.

Two things we bring

Quality for your patients. Revenue for your practice.

Quality

Reads that catch what others miss

The subspecialist best trained on pregnancy imaging reads every scan.

  • MFM physicians spend roughly 18 months of subspecialty training focused on obstetric imaging, far beyond a radiologist's few months or an OB/GYN's one to two. For the pregnant patient, MFMs are the imaging experts.2
  • The data backs it up. Across 6,400+ scans at 11 practices, MFM tele-interpretation found a potential missed diagnosis in 34.5% of scans sonographers had read as normal, cardiac anomalies most of all.1
  • Ouma follows AIUM, SMFM, ACOG, and ISUOG standards. The read sits with the subspecialist best trained to make it, raising diagnostic quality and reducing the referring provider's liability.
Revenue

Reimbursement you can't currently capture

The scans get read by experts, and the reads stay billable to you.

  • Obstetric ultrasound is reimbursed by level. A practice can only bill for the scan levels it is credentialed and equipped to perform and read. Many OB practices lack the subspecialty expertise for higher-level scans.
  • Partnering with Ouma opens that revenue back up. Patients get advanced, MFM-level imaging read in-house instead of referred out, and the associated reimbursement stays with your practice.
  • Quality and revenue come from the same decision. The scans get read by the experts, and the reads get billed where the care happens.

How it deploys

We adapt to how you already work

Ouma is built to slot into your existing imaging workflow rather than force a new one on you. Two places matter most.

Your reading software, or ours

Already running a PACS or reporting platform like ViewPoint or Astraia? We read natively inside your existing solution, no migration, no new logins for your team.

Don't have one, or don't want to manage it? We deploy our own cloud-based PACS, so the technology is our problem, not yours. Scans in, expert reads back.

Your sonographers, scanning at an MFM level

Ouma does not employ sonographers. Your sonographers stay your sonographers. What we add is the expertise behind them.

Our MFMs meet regularly with your scanning team, review studies, and give direct feedback. Over time your imaging gets better at the source, not just at the read.

Where we work

Wherever the scan happens, we're the reader

Lighten an MFM practice's read load

Already have MFMs? We take interpretation volume off their plate so your physicians can focus on the patients in front of them, added read capacity without added headcount.

Inside an OB/GYN office

We embed as the reader behind your office's scans, so patients get imaging and expert interpretation in one place. Your OBs shed the liability and skill burden of high-level reads.

Into maternity deserts

This is what Ouma has mastered. Patients get scanned close to home, but there is often no reliable expert nearby to read the study. We are that reader.

Study spotlight

We didn't just claim MFM reads catch more. We measured it.

The case for MFM interpretation is not a marketing line. It is published evidence, and Ouma helped write it.

In a peer-reviewed study of 6,403 obstetric scans across 11 practices, MFM tele-interpretation found potential missed diagnoses in 34.5% of scans that had been read as normal. Fetal cardiac anomalies were the highest-missed category.

Ouma's CEO, Dr. Sina Haeri, is a co-author. This is the exact problem our interpretation service exists to solve.

The read behind the desert

Across roughly 100 mobile-ultrasound sites and home-birth and community-midwife practices, patients can get a scan but often have no reliable expert to interpret it.3 The nearest MFM can be a two- to four-hour drive away.

Ouma is the reader on the other end of those scans. A mother in a maternity care desert gets subspecialty-level interpretation without the drive. It's the same gap our workforce research documents: more than 90% of U.S. counties have no practicing MFM,4 and roughly 35% are maternity care deserts.5

It's also why we partnered with Pulsenmore, whose FDA-authorized home-ultrasound probe lets patients perform basic scans from home under MFM supervision. The device puts the scan in the patient's hands; Ouma puts the expert behind the read.

The entry point into the broader teleMFM relationship

Ultrasound interpretation is often where a practice first works with Ouma, and it opens the door to the full subspecialty. These services extend the same MFM expertise across the rest of the pregnancy.

Frequently asked

Common questions about remote OB ultrasound interpretation

Our imaging partnerships team can set up reads in your PACS or ours.

Talk to our team →

Who reads OB ultrasounds for mobile and independent providers?
Ouma's board-certified maternal-fetal medicine physicians read them remotely. Every read is by an MFM subspecialist, not a generalist or software.

What is a 76811 detailed fetal anatomy scan?
CPT 76811 is the detailed fetal anatomic ultrasound, a more comprehensive evaluation than the standard 76805 anatomy scan. Ouma reads detailed anatomy scans to AIUM, SMFM, ACOG, and ISUOG standards.

Can you outsource OB ultrasound interpretation?
Yes. Ouma is a remote OB ultrasound reading service already serving roughly 100 mobile-ultrasound sites and community-midwife practices, returning same-day reads with no need to staff an in-house MFM.

How do mobile ultrasound providers get their scans read?
Scans flow to Ouma through your existing PACS or our proprietary cloud-based PACS; our MFM physicians interpret them and return the read the same day, licensed in all 50 states.

How fast is turnaround?
Same-day turnaround on ultrasound reads.

Do MFM reads actually catch more?
In a peer-reviewed study of 6,403 scans across 11 practices, 34.5% of normal sonographer reads had a potential missed diagnosis on MFM re-read, with cardiac anomalies the most frequently missed category. These reads sit within Ouma's tele-MFM program.
