Greater Regional Radiology offers a vast array of imaging services including: Nuclear Medicine; 3D Mammography; Ultrasound; Cardiac Ultrasound, PET Scan; in-house CT spiral scan and MRI scans; Bone Densitometry and all general X-ray procedures.

With our PACS system, you can easily complete your exams locally and we will ensure your exam results are quickly shared with your attending and specialty physician.

Nuclear Medicine:

Greater Regional installed a E. Cam Dual head machine in 2004.  This equipment is a variable dual headed system designed for cardiac imaging and general purpose nuclear medicine imaging. For this test, a patient is injected with a small amount of radioactive material called a tracer. The tracer will concentrate in the area of interest, and a nuclear camera will record the image for study by our radiologists.

The following exams are currently conducted in our Nuclear Medicine section:

  • Whole body bone scans
  • Limited bone scans
  • 3 phase bone scans
  • Myocardial perfusions
  • Hida scan
  • Solid gastric emptying
  • Liquid gastric emptying
  • Mugas
  • Venilation and perfusion lung scan
  • Parathyroid scan
  • I-123 Thyroid uptake and scan
  • TC Thyroid scan
  • Sentinel Node localization

For additional information regarding nuclear medicine exams available at Greater Regional, please call the Radiology Department at 641-782-3508.

3D Mammography:


Women who undergo routine mammograms now have the latest screening and diagnostic technology available to them at Greater Regional Medical Center in Creston. Greater Regional added the Selenia® Dimensions® breast tomosynthesis system in September 2013.

Greater Regional is one of the first women’s centers in Iowa to offer tomosynthesis for breast cancer screening. Breast tomosynthesis helps radiologists identify and characterize individual breast structures without the confusion of overlapping tissue. 

The center’s Selenia® Dimensions® breast tomosynthesis system is made by Hologic, a world leader in digital mammography. The system offers exceptionally sharp breast images, an advanced ergonomic design providing more patient comfort, and the ground-breaking tomosynthesis platform designed to deliver superior screening and diagnostic performance.

Breast cancer screening with tomosynthesis when combined with a conventional 2D mammography has a higher cancer detection rate than conventional 2D mammography alone.   Radiologists are reporting that tomosynthesis technology gives them increased confidence with a significant reduction in recall rates.


During a tomosynthesis exam, multiple, low-dose images of the breast are acquired at different angles.  These images are then used to produce a series of one-millimeter thick slices that can be viewed as a 3D reconstruction of the breast.

By offering women the latest technology in mammography, Greater Regional hopes to increase the number of area women who will be routinely screened.  Breast cancer is the second leading cause of cancer death among women, exceeded only by lung cancer.  Statistics indicate that one in eight women will develop breast cancer sometime in her lifetime. The stage at which breast cancer is detected influences a woman’s chance of survival. If detected early, the five-year survival rate is 98 percent. 

Greater Regional is committed to the fight against breast cancer. In offering breast tomosynthesis digital mammography. If you would like to schedule a mammogram or have questions about this important breast health procedure, please contact 641-782-3508.


Greater Regional added the Aplio Ultrasound and the Xario Ultrasound systems in 2009.  An ultrasound test is a non-invasive procedure that uses reflected sound waves to produce a picture of a blood vessel or internal organ. Ultrasound services are provided Monday through Friday by appointment at Greater Regional. Special instructions pertaining to your specific ultrasound examination will be provided by your physician.

Enhancing diagnostic confidence through the development of cutting-edge imaging technologies, Greater Regional Medical Center recently added the Toshiba America Medical Systems, Inc. -- AplioTM ultrasound system in 2012 which is the company's newest innovation for ultrasound examinations. This new technology offers the latest advancements in diagnostic performance and enhanced imaging and can perform a complete array of ultrasound exams including vascular, abdominal, obstetrics and gynecology procedures.

In addition, Greater Regional Radiology will now offer 3 dimensional and 4 dimensional real-time motion viewing for expectant moms between 24 and 32 weeks gestation who have had a normal fetal ultrasound.  Expecting parents will be able to purchase printed images and/or a CD of their baby.  This is a non-medical exam and not covered by insurance or interpreted by a physician.  To learn more about this opportunity, call 641-782-3508.  This technology purchase was made possible through contributions and donations made to the Greater Regional Healthcare Foundation.

Positron Emission Tomography Imaging (PET): 


Since 2005, Greater Regional has offered the Discovery ST, a PET/CT system completely optimized for cancer care. This system integrates a Positron Emission Tomography (PET) scanner with a multi-slice Computer Tomography (CG) scanner and is capable of 2D and 3D imaging with a larger bore for all patient studies or sizes. This Discovery ST system provides physicians with more sensitivity, speed, resolution, and diagnostic confidence when treating cancer patients. The “ST” in Discovery ST stands for “See and Treat,” which is what this system allows physicians to do. The Discovery ST assists our physicians in seeing the disease and planning radiation therapy treatment.  

Less time on the table means faster results and greater patient comfort.  The Discovery ST allows healthcare providers to not only “see” the disease, but begin to “treat” it.  

Before having a PET/CT scan, the patient receives a dose of a radiopharmaceutical tracer containing substances that mimic those normally used in the body including water, sugar, proteins, and oxygen. These tracers accumulate in diseased cells. During the scan, the tracers are detected by the system creating an image of the patient and highlighting any abnormal physiology. This image helps our physicians determine if disease is present, the location and extent of disease, and track how rapidly it is spreading.  

For additional information regarding PET scan exams available at Greater Regional, please call the Radiology Department at 641-782-3508.

Computerized Tomography Scan (CT):

To make CT exams as fast, safe and accurate as possible for patients, Greater Regional Medical Center  installed the AquilionTM PRIME CT system from Toshiba America Medical Systems, Inc. in March 2014.  Aquilion PRIME provides faster exams at as low as reasonably achievable doses, while producing high-quality images required for accurate diagnoses.

“The speed of the Aquilion PRIME enables our clinicians to obtain critical patient information for enhanced diagnoses faster than before,” explained JR Rockhold, Radiology Director.  “The design of the Aquilion PRIME allows us to successfully image a range of patients, from pediatric to bariatric, to further improve patient safety and comfort in our community. Our team is proud to have the most current state of the art technology to ensure the highest quality care and service for our patients.”

The Aquilion PRIME’s large bore opening offers a more spacious feeling for patients, while a higher table weight limit expands the range of patients who can be imaged. In addition, the Aquilion PRIME comes standard with industry-leading dose-reduction software.
In addition, the CT scan is also used for many of our cancer center patients in the preparation phases for radiation therapy. 

For additional information regarding CT scans available at Greater Regional, please call the Radiology Department at 641-782-3508.

Magnetic Resonance Imaging (MRI):

Greater Regional Medical Center added the Vantage Titan Magnetic Reasoning Imaging Equipment from Toshiba in-house in 2009. The Titan MRI system features Pianissimo TM technology, which reduces exam noise, to provide you with a quieter, more comfortable experience. Pianissimo is a musical term meaning play softly, so instead of the loud pounding other MRI systems produce, the sound you will hear is more like a gentle tapping. The quiet nature of our system also makes communications between you and the technologist easier.

Titan features an ultra-short, open bore providing a larger, more spacious environment during your MRI exam. The MRI sees through bone and soft tissue, and is especially helpful to diagnose brain and nervous disorders, such as tumors, certain spinal conditions, abnormal fluid in the skill, stroke and traumatic injuries. Like the CT scan, the MRI test is painless and non-invasive.

Your MRI exam provides doctors with high quality images they can use to diagnose and evaluate your physical condition. The Titan system provides more room in the magnet and less noise during the exam, so it is easier to remain motionless during your procedure.

Your comfort, combines with the latest exam techniques on our Titan, assures that your doctor gets the best possible images for the most accurate diagnosis.

What Should You Expect on Exam Day?

  • No special preparations are required prior to your exam. You may eat and drink normally, although it is best to limit your caffeine intake. Women should also refrain from wearing eye shadow or mascara.
  • Prior to the exam you will be asked to remove all jewelry and metal objects.  During the exam, just like a photograph, the most accurate images will be taken when you are still.
  • The technologist may place an MRI coil around the part of the body to be scanned.  Like an antenna, the closer the coil is to the area of interest on your body, the better the image quality of your exam.
  • MRI scans do not use any X-rays or other types of potentially harmful radiation.
  • Immediately following the scan, you may resume your normal activities unless otherwise directed by your physician.
