Indiana Radiologic Technologist Licensing Guide

Most of the radiology family in Indiana runs on the general license. A handful of credentials genuinely diverge, and those are the ones worth reading closely. Below is one subsection per real difference, then roll-up lines for everything else.

Nuclear Medicine Technologist

Divergence: separate license. Administers radiopharmaceuticals and performs nuclear medicine imaging procedures.

• Fee: $60 application, $60 renewal, every 2 years
• Credential: Listed as its own license category under 410 IAC 5.2-3-1; requires certification/registration in nuclear medicine technology (ARRT-N or NMTCB), distinct from the radiography credential

How it differs from the general license: Issued as a distinct license category, not folded under the radiographer license. A radiographer license alone does not authorize nuclear medicine practice; it requires its own nuclear-medicine certification and license.

Radiation Therapist

Divergence: separate license. Administers therapeutic radiation (radiation therapy) to patients.

• Fee: $60 application, $60 renewal, every 2 years
• Credential: Listed as its own license category under 410 IAC 5.2-3-1; requires current ARRT certification in Radiation Therapy from a JRCERT-accredited program

How it differs from the general license: A distinct license category separate from radiography. A radiographer license does not authorize radiation therapy; the therapist must hold ARRT-T certification and obtain the separate therapy license.

Limited-Scope X-Ray Operator (Limited Radiographer)

Divergence: limited-scope tier. Performs only the limited radiographic procedures within the scope of the specific limited license category held (e.g., dental, chest, chiropractic, podiatric, general, or cardiac catheterization).

• Fee: $60 application, $60 renewal, every 2 years
• Credential: Issued in defined limited categories (dental, chest, chiropractic, general, podiatric, and cardiac-catheterization radiography) under 410 IAC 5.2-3-1, each tied to a limited scope of practice rather than full ARRT radiography registration

How it differs from the general license: A reduced-scope credential below the full radiographer license. Each limited category authorizes only a narrow set of radiographic procedures and does not permit general radiography or fluoroscopy beyond its defined scope.

CT Technologist

Divergence: facility-credentialed. Performs computed tomography imaging; in Indiana this is done under the holder's base radiographer license with facility-level credentialing against ARRT post-primary CT certification.

• Credential: No separate Indiana state credential. ARRT post-primary CT certification (ARRT-CT) is pursued voluntarily and credentialed by the employing facility

How it differs from the general license: Indiana does not issue a CT license or add-on. ASRT lists Computed Tomography as not regulated by the state, so CT competency is verified by the hiring facility against ARRT post-primary certification rather than the state board.

MRI Technologist

Divergence: no state credential. Performs magnetic resonance imaging; not licensed or permitted by the state of Indiana.

• Credential: No Indiana state credential. MRI uses no ionizing radiation and is outside the radiation-control licensing scheme; ARRT-MR is a voluntary post-primary certification credentialed by the employer

How it differs from the general license: Indiana's licensing scheme is grounded in ionizing-radiation control (410 IAC 5.2 / IC 16-41-35), and MRI emits no ionizing radiation. ASRT lists Magnetic Resonance as not regulated, so the state issues no MRI credential.

Sonographer (Diagnostic Medical Ultrasound)

Divergence: no state credential. Performs diagnostic medical ultrasound; not licensed or permitted by the state of Indiana.

• Credential: No Indiana state credential. Ultrasound uses no ionizing radiation; ARDMS/ARRT-S certification is voluntary and credentialed by the employer

How it differs from the general license: Sonography is outside Indiana's ionizing-radiation licensing scheme. ASRT lists Sonography as not regulated by the state, so no state credential is issued.

Medical Physicist

Divergence: no state credential. Medical/health physics work; not licensed as an individual practitioner credential by Indiana under the radiologic technology scheme.

• Credential: No Indiana state license for medical physicists. The 410 IAC 5.2 scheme governs radiographers, nuclear medicine technologists, radiation therapists, and limited radiographers, not physicists; only a small number of states (e.g., TX, FL, HI, NY) license medical physicists

How it differs from the general license: Indiana does not issue an individual medical-physicist license under its radiologic technology rules. Medical physicist practitioner licensure exists in only a handful of states, which do not include Indiana per the 410 IAC 5.2 / IDOH framework.

Specialties that follow the general Indiana license

These run under the general radiologic technologist license and need no separate state credential: Mammography.

Before you pay: confirm your modality

Within radiology, whether a modality needs its own state credential is not consistent, and it is the thing travelers most often get wrong. MRI, nuclear medicine, radiation therapy, sonography, and CT can each be a separate state license in one state, a facility credential checked against your ARRT registration in the next, and nothing extra in a third.

The divergences we verified for Indiana are above. What we cannot see is your specific assignment and the site you land at. Before you submit any application fee for an advanced modality, confirm with your recruiter whether Indiana issues a state credential for it or whether the facility handles that against your certification. We would rather you ask first than pay for something the role never required.
