Market context
Texas allied-health employers often look for CT technologists with current ARRT registration, Texas Medical Board CMRT, AHA BLS, and prior CT experience, so demand tends to favor candidates who already meet core credentialing requirements. These roles are competitive because employers need clinicians who can work independently, maintain imaging quality, and keep pace with patient volume.
