What RadNet Is and How It Operates
RadNet is a network of imaging centers across the United States that provides diagnostic imaging services, including X-rays, CT scans, MRI scans, ultrasounds, and mammograms. The network operates in multiple states and serves patients who need imaging procedures ordered by their healthcare providers. Understanding what RadNet does can help you know what to expect when you schedule an appointment.

RadNet facilities are standalone imaging centers, meaning they focus specifically on taking and interpreting medical images rather than providing full medical care. A doctor or healthcare provider must order your imaging procedure before you can schedule an appointment. RadNet does not determine what imaging you need—your healthcare provider makes that decision based on your medical situation.
The company operates hundreds of imaging centers in different states, each staffed with radiologic technologists who operate the imaging equipment and radiologists who interpret the images. RadNet's role is to perform the imaging procedure and provide the results to your ordering physician. This separation of services means RadNet handles the technical imaging side while your doctor handles the medical decisions about your care.
RadNet facilities typically handle high volumes of patients, which means they are experienced in managing many different types of imaging appointments. The centers are designed to process patients efficiently while maintaining quality standards. Each facility has its own scheduling system and specific procedures, though they follow similar general processes across the RadNet network.
Practical takeaway: Before scheduling a RadNet appointment, confirm that your doctor has ordered an imaging procedure and obtain the order details. Know which type of imaging you need (X-ray, CT, MRI, ultrasound, or mammogram) and ask your doctor if there are any specific instructions you should follow before your appointment.
Pre-Appointment Scheduling and Preparation Steps
Scheduling a RadNet appointment is typically straightforward, though the exact process may vary by location. You can usually schedule by calling the facility directly or, at some locations, through an online scheduling system. When you call to schedule, have your insurance information ready along with your doctor's order or prescription for imaging. The scheduling staff will need to know what type of imaging you need and any medical details that might affect how the procedure is performed.

During scheduling, you will likely be asked several standard questions. The staff needs to know if you have any metal implants (such as pacemakers, metal joints, or dental work), as these can affect certain types of imaging, particularly MRI. They will ask if you are pregnant or might be pregnant, since this affects which imaging procedures are appropriate and how they are performed. You will also be asked about any allergies, particularly to contrast dyes, which are sometimes used during imaging procedures.
Different types of imaging require different preparation. For CT and X-ray procedures, preparation is usually minimal—you might simply need to wear comfortable clothing and remove metal objects. For MRI appointments, you will need to arrive early to complete safety screening forms. Ultrasound appointments often require you to fast (not eat or drink) for several hours beforehand, depending on what area is being imaged. Mammogram appointments may need to be scheduled at certain times in your menstrual cycle, and you should avoid using deodorant or powder on the day of the appointment.
When you schedule, ask the facility specifically what you should do to prepare for your particular type of imaging. Request written instructions if available, as these details are important to follow correctly. Some facilities mail preparation instructions, while others provide them over the phone or online. Write down the appointment date, time, location, and parking information. Ask how early you should arrive—most facilities ask you to come 10 to 15 minutes early to complete paperwork.
Practical takeaway: After scheduling, write down all preparation instructions specific to your type of imaging and follow them exactly. Call the facility back if you are unclear about any instruction, and mention any medical conditions or implants that might affect your imaging when you call to schedule or arrive for your appointment.
What Happens When You Arrive at the Facility
When you arrive at a RadNet facility, you will first check in at the front desk. Bring your insurance card and photo identification. You may also want to bring your doctor's order if you have a copy. At check-in, staff will confirm your personal information, insurance coverage, and the type of imaging you are scheduled for. This process typically takes 5 to 10 minutes. Expect to fill out or update patient registration forms, which ask for your medical history, current medications, and emergency contact information.

After check-in, you will be directed to a waiting area. The wait time before your imaging procedure begins can range from a few minutes to 30 minutes or more, depending on how busy the facility is and whether the previous patient's imaging took longer than expected. Many RadNet facilities have comfortable waiting areas with seating, and some have televisions or reading materials. Some locations offer online waiting room check-in systems that let you wait in your car until closer to your appointment time.
When it is time for your imaging, a radiologic technologist will call your name and bring you to the imaging room. The technologist is the person who operates the imaging equipment and takes the pictures. Before beginning the procedure, the technologist will explain what will happen during the imaging, answer any questions you have, and may ask additional screening questions about metal implants or allergies. For certain types of imaging, you may be given a hospital gown to wear and asked to remove jewelry, glasses, and other metal items.
The imaging room itself looks different depending on what type of equipment is being used. CT scanners look like large tunnels with a table that moves through them. MRI machines are similar but are typically louder and more enclosed. X-ray rooms have a large machine positioned over or beside a table or wall panel. Ultrasound rooms are quieter and more comfortable, with a bed and a monitor for you to potentially view the images. The technologist will position you and explain what you will feel or hear during the procedure.
Practical takeaway: Arrive 10 to 15 minutes early with your insurance card and ID. Be prepared to wait, and plan to spend 30 to 60 minutes at the facility total, though the actual imaging procedure is usually shorter. Wear comfortable, easy-to-remove clothing and avoid wearing metal jewelry or items that might interfere with imaging.
Understanding the Imaging Procedure Itself
The actual imaging procedure is painless, though you may experience discomfort depending on the type of imaging and your physical condition. X-ray procedures are quick, usually lasting only seconds to a few minutes. You stand or sit in front of an X-ray machine, and the technologist positions your body to capture the needed images. You will be asked to hold still and may be asked to hold your breath for a moment while the image is taken. X-rays involve brief exposure to radiation, but the dose is small and considered safe for diagnostic purposes.

CT scans take longer than X-rays, typically 10 to 30 minutes depending on what is being scanned. You lie on a table that moves slowly through a large machine. The machine makes soft clicking or whirring sounds. Some CT scans require contrast dye, which is a liquid you drink before the scan or that is injected through an IV. The contrast helps certain structures show up more clearly in the images. If you receive IV contrast, you may feel a warm sensation or slight metallic taste, which is normal and temporary.
MRI procedures are longer, typically lasting 30 to 60 minutes. You lie on a table and are moved into a large machine that creates strong magnetic fields and radio waves to produce images. MRI machines are significantly louder than CT machines, and you will hear banging or buzzing sounds during the scan. Some people find MRI uncomfortable because of the enclosed space, though most facilities now have larger or open-design machines that are less confining. You must remain very still during the scan. Some MRI scans also use contrast dye injected through an IV.
Ultrasound procedures typically last 20 to 45 minutes. You lie or sit on a bed, and the technologist applies a clear gel to the area being scanned and moves a handheld probe over the skin. The probe emits sound waves that create images on a monitor. Ultrasound involves no radiation and no discomfort, though you might feel slight pressure from the probe. During ultrasound, you can often see your images on the monitor, and the technologist may explain what they are seeing in real time.
Mammograms are brief procedures that usually take 15 to 30 minutes. You stand in front of the mammography
