About Our Radiologists

Our team is of Board-certified radiologists, residing within the USA, most with fellowship education. Physician credentialing is performed using the standards of the Joint Commission, which can allow credentialing at your facility by proxy. This decreases the credentialing burden on your own staff and speeds approval for medical staff privileges.

We typically assign a dedicated team of physicians to cover a facility. This allows Excalibur consistent, meaningful relationships between your facility, the referring physicians and technical staff.

Cardiology support is available with our Board-certified staff.

“Our small hospital in central Washington has no on-site radiologist and we have been using Excalibur for many years. We’re consistently impressed with the accuracy & speed of reads on all of our imaging needs. We can contact Excalibur 24/7 for any special needs or emergency interpretations.
