Finding a Location Near You

RAYUS Radiology locations span multiple states, though coverage is regional rather than nationwide, and available services vary by center. The most reliable way to confirm what’s offered near you is to use the official location search, entering your city, state, or ZIP code, then reviewing the specific exams and procedures listed for that site.

Some facilities operate under related brand names, such as Insight Imaging or regional partners like Midwest Breast Care, reflecting the network’s history of mergers with independent imaging providers. If your paperwork or signage shows a different name than “RAYUS,” it likely still connects to the same underlying scheduling, records, and billing systems.

Imaging Services Offered

Every RAYUS Radiology imaging center offers a distinct mix of services, so confirming what’s available at your chosen location matters before you schedule.

Core diagnostic imaging includes MRI — available in high-field, 3T, open, and open upright configurations, along with specialized studies like MRI enterography and elastography — CT (including CT angiography, virtual colonoscopy, lung cancer screening, and cardiac calcium scoring), standard X-ray and fluoroscopy, and ultrasound, including ultrasound-guided biopsy and vascular screening exams.

Breast imaging covers 2D and 3D mammography, breast ultrasound, breast MRI, image-guided biopsies, and breast cancer risk assessment. PET/CT and nuclear medicine support cancer staging and neurological evaluation, bone density (DXA) scans assess osteoporosis risk, and EKG offers a quick, non-invasive heart screening.

Separately, dedicated pain and vascular care programs provide image-guided procedures such as epidural steroid injections, facet joint injections, radiofrequency rhizotomy, vertebroplasty, varicose vein treatment, and peripheral artery disease treatment, performed by interventional radiologists rather than diagnostic technologists.

Outpatient Imaging vs. Hospital Imaging

Many patients referred for imaging can choose between a hospital radiology department and an independent outpatient center. The two settings differ in cost, convenience, and comfort.

The right setting depends on your clinical situation and insurance network. Hospital imaging is necessary for emergencies or inpatient care, while independent outpatient centers are generally built around routine, physician-referred exams. Confirm with your doctor and insurer which setting applies to your specific case, since facility fees and network coverage vary by plan.

How to Schedule an Appointment

Most appointments begin with a referral from your physician, who sends an order to the imaging center. Staff often call patients directly beforehand to review preparation instructions and confirm whether any prior imaging is on file for comparison. You can also contact your chosen center directly to schedule or ask exam-specific questions, since online self-scheduling availability differs across individual locations rather than functioning as one unified national system.

If you need to cancel a RAYUS Radiology appointment, most centers require at least 24 hours’ notice.

Appointment Checklist

Bring the following to every visit, regardless of exam type:

• Photo ID
• Insurance card
• Physician referral or order form
• Current medication list
• Prior imaging (CDs, films, or reports), if instructed
• A list of any implants, metal fragments, or medical devices

Why prior imaging matters: When a radiologist can compare your new scan against previous exams, they can identify interval changes — whether something has grown, shrunk, or stayed stable over time. This comparison often improves diagnostic accuracy and can reduce the need for additional follow-up testing that would otherwise be ordered just to establish a baseline.

Arrive 15 minutes early, wear comfortable clothing, avoid underwire bras and metal fasteners, and leave valuables at home.

Preparing for Your Exam

General guidelines apply across most exams, but specific requirements depend on what you’re having done.

MRI: Most MRI exams require no dietary restriction, and you can take medications as usual, with exceptions for certain specialized studies like MRCP, which requires no eating or drinking for four hours beforehand. You’ll remove all metal, including jewelry, and change into scrubs, since even some fabrics contain trace metal that poses a burn risk near the scanner’s magnetic field. Patients with pacemakers, aneurysm clips, metal fragments in the eyes, or other implanted devices must notify staff before scheduling, since some devices make MRI unsafe or require special protocols.

CT with contrast: Avoid eating or drinking anything except water for four hours beforehand. Contrast is typically administered through an IV in your hand or arm.

Ultrasound: Preparation depends on the body part. Pelvic ultrasounds for patients under 18 or those being evaluated for fibroids require drinking 24 ounces of water two hours prior; kidney ultrasounds require avoiding food and drink for at least two hours; gallbladder and abdominal ultrasounds require six to eight hours of fasting; vascular ultrasounds need no preparation.

Cardiac calcium scoring CT: Avoid caffeine and other stimulants for three hours before your appointment.

Breast biopsy and injection procedures: Bring details of prior mammograms performed elsewhere, and arrange for someone to drive you home afterward.

What Happens During Your Visit

Understanding the flow of a typical appointment can ease first-visit anxiety. While details vary by exam type, most visits follow a similar structure:

1. Check-in. Arrive 15 minutes early, present your ID and insurance card, and complete any outstanding paperwork.
2. Health screening. A technologist reviews a short health questionnaire, confirms your identity, and discusses any allergies, implants, or pregnancy status.
3. Changing area. For most exams, you’ll change into a gown or scrubs and store your belongings in a locker.
4. Contrast discussion, if applicable. If your exam requires contrast, staff explain the process and place an IV before the scan.
5. The scan. A technologist positions you on the exam table. For CT and MRI, the technologist operates the scanner remotely from an adjoining room while communicating with you throughout.
6. Recovery and discharge. For most diagnostic scans, you simply change back into your clothes and leave — no formal checkout is required. Interventional procedures like injections or biopsies may include a brief monitored recovery period first.
7. Results timeline. Your images are sent electronically to a radiologist for interpretation, and a report goes to your referring provider. If additional images are needed, staff typically call within 24–48 business hours to schedule a follow-up.

Managing Claustrophobia or Anxiety

If you’re concerned about feeling closed in during an MRI, select centers offer alternatives including High-Field Open MRI, which has open sides with nothing pressing on your arms or shoulders, and Open Upright MRI, where you’re typically seated or standing with nothing in front of your face. These options aren’t available everywhere, so ask when scheduling if this is a concern. During any MRI, you can use an emergency call button to stop the exam at any time, request headphones for music, or use breathing techniques and an eye covering to help manage anxiety.

Accessing Results Through the Patient Portal

The RAYUS Radiology patient portal lets you view exam information and results online. Because the network has grown through mergers with other imaging providers, the specific portal system you’ll use depends on where you were seen — some patients use a portal tied to their regional center, others use a broader shared system across the wider network, and mammography patients typically use a separate portal designed for breast imaging results, accessed by entering their date of birth.

If you don’t already have a login, you generally can’t self-register. Call the center where you had your exam or where you’re currently scheduled, and staff will verify your identity and issue an access code or email invitation.

Patient Portal Troubleshooting

If you’re having trouble accessing your results, these are the most common issues and how to resolve them:

• Invitation expired or never arrived. Portal invitations are time-limited. Call your local center to request a new one rather than trying to re-register on your own.
• Logged in but can’t find your exam. You may be using the wrong portal for your exam type. If you were seen at a mammography-specific site, try the dedicated breast imaging portal instead of the general one, or vice versa.
• Forgot your username or password. Use the self-service password reset option on your portal’s login page, which requires your registered username. If you no longer know your username, contact the center where you had your exam.
• Report appears but images won’t load. This is often a browser or connection issue. Try a different browser, clear your cache, or check your internet connection before contacting support.
• Results not showing days after your exam. Portal availability depends on when the radiologist finalizes the report and it syncs to the system; if it’s been longer than staff indicated at your visit, call your local center directly.

Insurance and Billing

Most major insurance plans are accepted, though coverage and network status vary by location and by your specific plan, so verifying acceptance at your chosen center is worthwhile before scheduling.

Common Insurance Scenarios

• Commercial insurance: Your copayment, coinsurance, and deductible apply according to your plan’s in-network benefits, and the imaging center bills your insurer directly.
• Medicare: Imaging is generally covered under Medicare Part B when medically necessary and properly ordered, subject to your standard Part B deductible and coinsurance.
• Prior authorization: Many insurers require pre-approval before advanced imaging like MRI, CT, or PET/CT. This is typically initiated by your referring physician’s office, and your appointment may need to wait until authorization is confirmed.
• Self-pay: If you’re uninsured or choosing to pay out of pocket, ask your local center about self-pay pricing before scheduling.
• Out-of-network: If your plan doesn’t include your chosen center, you may face higher out-of-pocket costs; check network status in advance, though federal balance-billing protections may still apply in certain situations.

Paying Your Bill

You can pay online as a guest or by creating an account to view statements and enroll in paperless billing, by phone through the number listed on your statement, by mail using the payment coupon included with your bill, or by applying for financial assistance through the billing office if you’re having trouble affording your bill.

Your Rights Under the No Surprises Act

Outpatient imaging providers are subject to the federal No Surprises Act, which protects patients from unexpected balance billing — for example, when an out-of-network radiologist reads your scan at an in-network facility without your knowledge. In these situations, you’re only responsible for your normal in-network cost-sharing amount, and the provider cannot bill you for the difference. If you believe you’ve been incorrectly billed, you can dispute the charge through your insurer or the federal No Surprises Help Desk.

How Results Reach Your Doctor

After your exam, images are transmitted electronically in DICOM format — the standard medical imaging file type — to a board-certified radiologist, who reviews the study and generates a diagnostic report. That report is delivered to your referring provider through the imaging network’s reporting infrastructure, often the same system (PACS, or picture archiving and communication system) that stores and shares the images. If you need a personal copy of your images for surgery or a second opinion, most centers can provide a CD or film through their medical records office on request.
