Radiology is used by almost every patient, from the routine to the comPlex.

St. John leads the way with our all-digital imaging system. This technology brings higher image quality and faster review times so doctors can more easily diagnose patients and begin treatment sooner. All tests are read by a board-certified radiologist.


Regular Mammograms can save your life.

A mammogram is an x-ray that detects breast tumors or other conditions. Talk with your doctor about how often you need a mammogram screening. Early detection is the key to beating breast cancer, and regular tests could save your life. St. John is committed to offering the best mammography equipment available.

Our comfortable, relaxing mammography suite employs all-digital imaging technologies to detect cancerous areas that may be missed with traditional mammograms. Diagnosis is further enhanced by computer-aided detection (CAD), which marks areas of concern for further examination by your doctor.

To make an appointment for a mammogram at St. John, please call 918-856-5789.  Please complete a mammography history sheetand bring it with you to your appointment.

Magnetic Resonance Imaging (MRI) uses magnets and radio waves to form detailed pictures of cross sections of internal body tissues.

These cross sections are then assembled into three-dimensional computer images called slices.  Our open-bore MRI offers peace of mind to patients hesitant about traditional MRIs due to claustrophobia or anxiety.

Please download the MRI patient questionnaire and bring it with you to your appointment.

CT Scans

Computed Tomogrpahy (CT) combines x-rays with computer scans.

Multiple cross sectional images of the body are taken and assembled by a computer into three-dimensional images. Our 64-slice CT scanner provides exceptionally detailed views of the diagnosis area with the lowest radiation exposure for the patient.

Preparing for your CT scan: If a contrast agent is to be used in your CT scan, you should not eat solid food for four hours prior to the exam. To protect your kidneys, we ask that you drink 3 (12-16 oz) glasses of clear liquid within the four hours prior to your exam, unless you have a fluid restriction.

Bone Density

This full-body imaging system enables physicians to detect changes in patients' bone density quickly and without discomfort.

Bone density scans detect areas of increased or decreased bone mass and can aid in identifying abnormal processes such as a tumor, infection or fracture.


Ultrasound uses sound waves to examine and measure internal body structures and detect abnormalities.

Many people associate ultrasounds with checking a baby's health during pregnancy, but they can also be used for abdominal, breast, carotid and blood vessel exams.

St. John offers a full-spectrum of routine and fluoroscopy procedures. For supplemental information, visit the American College of Radiology.

Nuclear Medicine

Nuclear Medicine is the study of treatment of disease in the internal organs and tissues.

Positron Emission Tomography (PET), an advancement in Nuclear Medicine and digital imaging, is an exam which uses the injection of a radiopharmaceutical to display chemical functioning of organs and tissues undetectable through any other means.

Interventional Radiology

Interventional X-ray studies which allow doctors to see into the body's major blood vessels. The procedure involves inserting a very thin tube (catheter), injecting a contrast agent into the tube and then taking X-rays.
