In the 28w scan when they didnt get a clear shot of her spine the report said questionable sacrococcygeal open neural tube defect?

Get another scan. Scan quality varies with the equipment used and the experience of the tech.Some physicians spend most of their work day doing high resolution scans that are the most specific for determining what is going on.I would check with the OB and review the scan.See if a better scan is available or what else they can do to confirm what is going on.
