Where to Get Imaging Services in Chattanooga: Facilities, Access Points, and What to Expect

Imaging services in Chattanooga range from emergency departments that perform basic X-rays to specialized centers offering advanced MRI and CT protocols. This guide covers where to access imaging across the city, what each setting provides, and how to navigate referral pathways and scheduling—information that matters when you need results quickly or want to avoid unnecessary delays.

Hospital-Based Imaging: Erlanger and Baroness

Erlanger Health System operates the largest imaging network in Chattanooga. The main campus on East Third Street houses a full-service radiology department with CT, MRI, ultrasound, and fluoroscopy capabilities available 24 hours. Erlanger's emergency department performs imaging on-site; inpatient imaging turnaround for routine CT studies typically runs 2 to 4 hours, though acute presentations (stroke protocol, trauma) are prioritized. Erlanger also staffs interventional radiology, which handles image-guided biopsies, drainage procedures, and vascular interventions.

Baroness Hospital, located in East Brainerd, operates as a smaller acute-care facility with basic imaging capacity. It has radiography and ultrasound on-site but refers most CT and MRI studies to partner facilities. If you present to Baroness with a condition requiring advanced imaging, expect a transfer arrangement or a referral back to a center with those capabilities on campus.

Both hospitals accept Medicare, Medicaid, and commercial insurance. Out-of-pocket costs for imaging vary by study type and whether it is performed in an emergency or outpatient setting. A routine chest X-ray billed to insurance typically results in a patient responsibility of $50 to $150 after insurance; an MRI of the brain can range from $300 to $800 depending on complexity and insurance coverage. Uninsured self-pay patients should ask about financial assistance programs; Erlanger administers a sliding-scale indigent care fund.

Standalone and Outpatient Imaging Centers

Several independent imaging centers operate throughout Chattanooga, offering shorter wait times and sometimes lower out-of-pocket costs than hospital settings.

Diagnostic imaging at urgent care and imaging-only facilities: These centers focus on X-ray and ultrasound services and are used for straightforward cases—ankle sprains, shoulder pain, first-trimester pregnancy confirmation. They typically schedule same-day or next-day appointments and charge $80 to $200 for a single radiograph, less than a hospital copay for some insurance plans. These centers do not provide CT or MRI.

Specialty imaging networks: A few centers in the Chattanooga area offer open-bore or wide-bore MRI equipment, which matters for patients who are claustrophobic or obese (>300 pounds). Standard MRI machines have a 60-centimeter bore; wide-bore machines are 70 centimeters or larger. If you have known claustrophobia or weigh over 300 pounds, confirm bore size when scheduling rather than arriving unprepared. These specialized machines may add $100 to $300 to the cost of an MRI study, but insurance often does not distinguish, so you may not see a charge difference at the point of service.

Imaging in North Shore and East Brainerd

North Shore residents can access imaging through Erlanger's outpatient centers (the system operates imaging suites in addition to the main hospital). East Brainerd has Baroness and nearby independent centers. Southside imaging options are more limited; many Southside patients travel to East Third Street (Erlanger main) or to the North Shore for outpatient studies. Wait times to schedule an outpatient MRI or CT in Chattanooga typically run 1 to 3 weeks for non-urgent referrals; urgent studies (stroke, acute trauma) are performed immediately.

Insurance and Referral Pathways

Most insurers require a physician order before imaging. If you have imaging ordered by your primary care doctor or a specialist, call the facility directly to verify that your insurance is accepted and to confirm your coverage level. Some insurance plans designate preferred facilities where your copay is lower; imaging at an out-of-network center may incur higher patient responsibility. Ask your insurance company which facilities are in-network for imaging before scheduling.

Self-pay patients without insurance should ask facilities about cash-pay rates, which are sometimes 30 to 40 percent lower than the insurance allowable fee. Some centers negotiate directly with uninsured patients; it does not hurt to ask.

Pediatric Imaging

Erlanger operates a dedicated pediatric imaging section. Pediatric protocols use lower radiation doses than adult protocols and are calibrated for children's anatomy. If your child needs imaging, request a pediatric facility; adult machines and protocols increase unnecessary radiation exposure. Erlanger's pediatric radiologists specialize in reading children's studies, which improves diagnostic accuracy for conditions like intussusception or developmental hip dysplasia.

What You Need to Know Before Your Appointment

Bring your insurance card and photo ID. If you have had imaging at another facility, request those records—comparing old and new images can be diagnostically important and saves time. For MRI, disclose any metal implants (pacemakers, some aneurysm clips, metallic foreign bodies in the eye) before the appointment; these contraindicate MRI entirely or require special protocols.

Fasting is required for abdominal ultrasounds (nothing after midnight) but not for most CT or MRI studies. Confirm fasting requirements when you schedule. Bring a list of current medications. If you are pregnant or suspect pregnancy, tell the facility; X-ray and CT are typically avoided in pregnancy, though ultrasound is safe throughout.

For outpatient studies, allow 30 to 45 minutes for check-in and the study itself. Results are typically available within 24 hours; your ordering physician receives the report, and you can request a copy. Do not assume absence of results means there is nothing wrong—contact your doctor if you have not heard back within 2 business days.

The choice between hospital-based and standalone imaging depends on urgency, complexity, and insurance coverage. Emergency and inpatient imaging goes to hospitals by necessity. Routine outpatient studies (follow-up CT, spine MRI) can often be scheduled at independent centers with shorter wait times. Your referring physician can steer you to an appropriate facility, but asking about scheduling wait times and your out-of-pocket responsibility before booking saves frustration later.
