Cass Regional Medical Center's medical imaging department utilizes some of the most advanced radiologic technology available, including a 1.5T, 70 cm bore Siemens Aera MRI (magnetic resonance imaging machine), a 64-slice high-speed CT, a 16-slice CT scanner, PET/CT, teleradiography, digital mammography, vascular sonography, echocardiology (including transesophageal—TEE), nuclear medicine, nuclear heart procedures, fluoroscopy, tomography, state-of-the-art ultrasound, stereotactic breast biopsy, and bone densitometry. Cass Regional's medical imaging department utilizes PACS (picture archiving and communications system), through which crystal-clear digital diagnostic images (such as x-rays and CT scans) are quickly taken and transferred electronically to the radiologist for interpretation. The medical imaging department also periodically offers reduced-rate mammograms. Radiologists interpret test results on-site and via teleradiography 24 hours per day.

All imaging tests and procedures can be scheduled through Cass Regional's central scheduling department by calling 816.380.5888, ext. 7880.

Imaging procedures

Bone density

Dexa, or bone density testing, which is used to measure bone strength and diagnose osteoporosis, is available Monday through Friday from 8 a.m. to 4:30 p.m.


Computed tomography (CT) uses x-rays to provide detailed pictures of structures inside the body. CT scans of the brain, soft tissue neck, sinus and facial bones, chest, pulmonary embolism, abdomen and pelvis, appendix, spine, upper and lower extremities, angiography, and CT-guided biopsy are available 24 hours a day, 7 days a week. 

Calcium scoring CT and cardiac CT are available by request.


Recent studies have suggested that 3-D mammography, when used in conjunction with traditional 2-D digital mammograms, leads to higher rates of cancer detection and reduces false alarms for patients.

"3-D mammography is especially beneficial for the 25 percent of women who have dense breasts," explains radiologist Aaron Lewis, MD. "Greater tissue density decreases the sensitivity of traditional 2-D mammograms, because the overlapping structures can hide a tiny cancer or create something that looks like a mass but is not. With 3-D mammography, we can potentially find smaller cancers earlier and reduce the number of callbacks for additional testing."

3-D mammography and digital mammography with CAD is available Monday through Friday from 7:30 a.m. to 5:30 p.m., and on the first Saturday of each month from 7 a.m. to noon. 

Breast sonography is available Monday through Friday from 6:30 a.m. to 5:30 p.m.

Needle localization breast biopsies and stereotactic breast biopsies are available Monday through Friday from 8 a.m. to 4:30 p.m.


Magnetic resonance imaging (MRI) uses a magnetic field and pulses of radio wave energy to provide detailed pictures of organs and structures inside the body including:

  • Imaging of the brain and brain stem. 
  • Bone marrow bleed.
  • MR angiography-brain.
  • MR angiography-neck.
  • MRI internal auditory canal structures, pituitary, orbit, temporomandibular joint, abdomen, breast and pelvis.
  • MR angiography-abdomen.
  • MR angiography-chest, pelvis, Eovist, liver.
  • MR cholangiopancreatography.
  • Upper and lower extremities and spine.
  • MR angiography-pelvis.

MRI services are available from 8 a.m. to 5 p.m. on Monday, Wednesday and Friday and from 8 a.m. to 8:30 p.m. on Tuesday and Thursday.

Nuclear medicine

Nuclear medicine scans utilize a special camera to provide detailed pictures of structures of the body. These pictures are taken after a radioactive tracer is inserted in the arm and absorbed by the tissues and organs.

Bone scan, biliary, thyroid, gastric emptying study, GI blood loss scan, lung scan, liver, spleen, renal scan and renal captopril is available Monday through Friday from 6:30 a.m. to 4:30 p.m.

Nuclear stress testing, pharmacological nuclear stress and MUGA scan is available Monday through Friday from 6:30 a.m. to 4:30 p.m. 


Positron emission tomography (PET) scans utilize a special camera and radioactive tracer to view organs of the body. This scan is done in conjunction with a CT scan, combining both procedures into one single exam. This procedure is available every other Tuesday. 

Sonography (ultrasound)

Sonography testing creates imaging of soft tissue structures of the body by transmitting high-frequency sound waves and recording the information on a monitor.

Abdominal, prostate, pelvic, transvaginal pelvic, OB, aorta, chest, breast, kidney, liver, neck (soft tissue), pancreas, testicle and thyroid sonograms are available Monday through Friday from 6:30 a.m. to 7 p.m. and can be performed by an on-call technologist after hours and on weekends, if necessary.

Carotid doppler, venous sonography, arterial doppler, ankle-brachial index tests, and renal dopplers are available Monday through Friday from 6:30 a.m. to 7 p.m.

Ultrasound guided needle, ultrasound guided abscess drainage, prostate biopsy, paracentesis and thoracentesis procedures are available Monday through Friday from 7:30 a.m. to 4:30 p.m. 

Stress echocardiograms are performed Monday through Friday from 7 a.m. to 5 p.m.

Transesophageal echo (TEE) is a type of echo in which the ultrasound transducer, positioned on an endoscope, is guided down a patient's throat into the esophagus. The TEE test provides a closer look at the heart's valves and chambers, without the interference from the ribs or lungs. This test can only be performed at the request of a cardiologist. Cass Regional performs TEE tests Tuesday through Friday. 

X-ray and diagnostic radiology

Routine x-rays, myeolograms (cervical, thoracic and lumbar), hysterosalpingiograms, arthrograms, sialograms and Dobbhoff placement are available 24 hours a day, 7 days a week. Fluoroscopy (GI, barium enema, air contrast barium enema, barium swallow and esophograms) are available Monday through Friday from 7:30 a.m. to 4:30 p.m.
