Expertise and professionalism in radiology

The Regional Imaging Center, located inside Terre Haute Regional Hospital, provides diagnostic imaging examinations for outpatients, inpatients and emergency room patients. Our imaging services staff is experienced and knowledgeable, ensuring quality diagnostic images.

Our technologists are skilled in anatomy, patient positioning, examination techniques, radiation safety and basic patient care. Registered radiologic technologists, RT (R), must complete a minimum two-year formal education and must pass a national certification examination. To maintain their registration, they must earn continuing education credits every biennium.

Diagnostic images are interpreted by a radiologist. A radiologist is a physician who earns a four-year doctoral degree to become an MD or DO. Then they complete a four-year residency in diagnostic radiology.

Regional Hospital’s imaging services provides a registered nurse during all invasive procedures performed within our department. During the procedure, a nurse will monitor your vitals, assist the radiologist and administer medication when needed.

Terre Haute Regional Hospital has a Radiation Safety Committee (RSC), which meets on a routine basis to review the safe usage of radioactive materials and radiation generating equipment. The RSC ensures that all employees working near radioactive materials have sufficient training and experience to perform their duties in accordance with the regulatory requirements. The committee also reviews the process for radiation safety of all employees, patients and visitors.

Imaging results and next steps

After you receive your examination, your radiologist reviews and dictates the results of the examination. Then the radiologist sends the report to the ordering physician. Your referring physician will then discuss the results with you.

Please note that the technologist will not be able to provide the results of your examination.

A copy of your examination is available to you for a specialist referral, comparison study or second opinion. We can provide you with a CD or film copy at the time of your exam, or it can be requested by calling (812) 237-1625. When you pick up your examination results, you will need to bring picture identification.

Imaging services provided

Diagnostic imaging

Diagnostic imaging is also known as x-ray. The examination uses electromagnetic energy beams to produce images onto film or on a computer. A computer processes the image, which is called computerized radiography or digital radiography. X-rays are used to visualize the inside of the human body looking for injury or illness. The most common types of x-rays are of bones, the lungs and the abdomen.


A fluoroscopy is a type of x-ray that is visible at the immediate time of the image. This is sometimes referred to as a “live x-ray.” It is viewed on a monitor that resembles a television. The most common types of examinations that use fluoroscopy are:

  • Upper gastrointestinal series (UGI)
  • Barium esophogram
  • Air contrast barium enema (ACBE)
  • Barium enema (BE)
  • Voiding cystourethrogram (VCUG)
  • Cystograms
  • Modified barium swallow (3-phase swallow study or cookie study)
  • Hysterosalpingograms
  • Fistulagrams/sinus tract injection
  • Diaphragm movement (sniff test)

Computed Tomography (CT)

A CT scan consists of a rotating x-ray machine that generates images in a “slice-like” format, much like the slices in a loaf of bread. A CT scan is used to diagnose many conditions such as tumors, bone fractures, bleeding blood clots and more. CT scans are invaluable for examining an organ’s size and shape and in the evaluation of many different diseases.

CT examinations can vary in time from 10 minutes to more than an hour, depending on the area of concern. The technologist will place you on a table with a small pad. The table will move automatically through a large cylinder. Some scans require you to hold your breath, but you can be assured your technologist will instruct you about this. An IV will be needed for contrast administration, if needed.

MRI (magnetic resonance imaging)

Magnetic resonance imaging differs from traditional x-rays in a number of ways. MRI’s utilize radio waves and a strong magnetic field, which allows them to produce very detailed, cross-sectional images of the body. An MRI is similar to a CT scan, but the MRI is conducted without the use of radiation.

The length of an MRI can vary from 30 minutes to two hours per section of anatomy being imaged. You will be asked to remove jewelry, glasses, coins, keys, credit cards and any clothing with metal objects. The technologist conducting you MRI will place a special plastic or padded coil around the body part being examined. You should not feel anything during the scan.


Terre Haute Regional Hospital’s imaging services department provides MRI, CT and diagnostic radiographic arthrograms. An arthrogram is a procedure that entails having the radiologist insert a small needle in to the joint of interest and injecting contrast media and/or medication. After the contrast media is injected, images are taken in the appropriate modality (MRI, CT or diagnostic radiography).

Nuclear medicine imaging

Nuclear medicine imaging is unique because it documents the structure and the function of a specific body part. Specialists use nuclear medicine as a treatment of a disease and/or disorder. A nuclear medicine technologist administers small amounts of radioactive material, called radiopharmaceuticals, to the patient to obtain diagnostic information about organs, bone and tissue. The technologist uses a special camera and computer to create an image for the radiologist to interpret.

At Terre Haute Regional Hospital, our nuclear medicine department is in accordance with the National Regulatory Compliance (NRC). This governmental agency oversees reactor safety and security; radioactive material safety, security and licensing; plus fuel management, including storage, disposal and recycling.

Your examination will require a radioisotope to be administered intravenously, by inhalation or by ingestion. You will be given specific instructions prior to and after your examination. If you have any questions, please call the imaging services department at (812) 237-1625.

Ultrasound (sonogram)

Sonographers use high frequency sound waves to obtain images of organs and tissues in the body. No radiation is used during ultrasound examinations.

Sonographers within the imaging department at Terre Haute Regional Hospital use the most advanced ultrasound equipment, with color flow/spectral analysis Doppler and gray scale imaging with 3-dimensional capabilities. These comprehensive ultrasound services include:

  • Obstetrical
  • Gynecologic
  • Abdominal echo
  • Breast imaging
  • Thyroid
  • Gall bladder
  • Renal
  • Superficial lump testing
  • Organs/tissues of concern

The majority of ultrasounds are painless. Patients might experience discomfort during the examination due to the pressure applied to the area of concern. A warm gel will be applied to the area being scanned. If you have any questions, please contact the imaging services department at (812) 237-1625.

Fetal ultrasound 4-D/3-D

4-D/3-D imaging of the unborn child is offered as an imaging service for entertainment purposes only. It produces images of the facial, hand and feet features of the child to be given to the mother, but the images will not be read by the radiologist as a diagnostic procedure. It is suggested that this be performed at 28 to 32 gestational weeks.

Bone densitometry and BMI

Bone densitometry is a type of imaging examination that measures your bone mineral density. This test can detect low bone density before a fracture occurs. It can also predict chances for future fractures, confirm an osteoporosis diagnosis, determine rates of bone loss and monitor the effects of treatment. Terre Haute Regional Hospital utilizes a state-of-the-art DXA densitometer.

For those who desire an accurate body mass index (BMI), our bone density machine can also supply a printout of your exact BMI.

Patients must be at least 20 years of age and weigh less than 350 pounds. We ask that patients refrain from taking calcium supplements for 12 hours before their examination. The examination takes approximately 20 minutes to complete.


At Terre Haute Regional Hospital, we utilize mammograms and digital mammography to help maintain breast health and detect possible lumps as early as we can. It is suggested that women over the age of 40 receive an annual mammogram. For more information on women’s health and mammography, please visit our mammography page.

PET scan

Positron emission tomography (PET) is a test that uses special imaging cameras and a radioactive type of sugar to produce pictures of the function and metabolism of the cells in the body. Computerized tomography (CT) is an x-ray test that generates a detailed view of the anatomy or structure of organs and tissues in the body. The CT scan can show the dimension of vessels, lymph nodes and organ systems. A PET/CT scan merges both technologies into a single machine. It provides a picture of function (PET), a picture of anatomy (CT) and a merged picture of both the body’s metabolism and structure.

Prior to your examination, you should inform your physician or technologist if you are diabetic or if there is a chance you are pregnant. Your PET/CT scan will require an intravenous injection and you will be asked to drink fluids following the examination.

Prior to the exam, you will receive a small injection of radioactive sugar (FDG). You will be asked to sit or lie down on a stretcher or sit in a chair for 30 to 60 minutes while the FDG travels throughout your body. The technologist will then assist you to the scanner. The CT portion of the exam is completed first, followed by the PET portion. You may be asked to hold your breath for several seconds while the CT scan is performed.

The length of the exam is determined by your height and the area of interest. Most PET/CT scans are typically completed within 20 to 40 minutes. When the total scan is finished, the computers will produce images for the doctor to review.

Interventional radiology

Interventional radiologists specialize in minimally invasive, targeted treatments, performed using imaging guidance. These often are a good alternative to surgery, because they are less invasive and less risky. The patient benefits by experiencing less pain, with a shorter recovery time. Interventional radiologists guide small instruments, such as catheters, through the blood vessels or other pathways to treat disease.

Biopsies are safely performed with imaging guidance such as ultrasounds, mammography, x-ray and/or computed tomography (CT). These types of imaging are used to determine exactly where to place the needle and perform the biopsy. Often, tissue is removed by placing a needle through the skin to the area of abnormality. Once the tissue is removed, it is delivered to the laboratory for further testing.

Drainages and aspirations can be safely performed by using an ultrasound, mammography, x-ray, and/or computed tomography (CT). These types of images determine exactly where to place the needle and perform the procedure. An image-guided drainage or aspiration is the removal of fluid that relieves pressure and may be examined for disease. Often, the fluid is removed by placing a needle through the skin to the area of abnormality. Once the fluid is removed, it may be delivered to the laboratory for further testing.
