Diagnostic Imaging

Advanced MRI

St. Joseph Mercy Hospital in conjunction with St. John River District Hospitals offer access to Magnetic Resonance Imaging (MRI) through Advanced MRI.

An MRI is an imaging technique that produces detailed pictures of internal organs and tissues. The images are created through the use of magnetic fields and radio waves. For some procedures a contrast agent is used to increase the detail of the image. As most MRI services are provided on an outpatient basis, Advanced MRI is pleased to offer two locations to best meet patient's needs, including: 

Mercy Health Center, in Fort Gratiot Township
St. John River District Hospital, East China Township

For more information about Advanced MRI services or to make an appointment, please call 810-985-1455.

PET Scan

Positron Emission Tomography (PET) is a test that combines computer tomography (CT) and nuclear scanning to assist physicians with the diagnosis of disease and treatment planning. PET images are different than more traditional radiology studies. X-ray, CT, Ultrasound or MRI procedures look at the structure of different organs. PET images contain information about the body's chemistry and cell function. PET scans combined with other radiology procedures give your doctor powerful information that can aide in your care.

Although used for a number of diagnostic procedures, PET-CT is most readily used in the diagnosis and treatment planning for cardiology, neurology and cancer studies.

PET-CT is provided at Mercy Health Center through a mobile unit that visits the community each week.

7 a.m. - 6 p.m. Mondays
Mercy Health Center, Fort Gratiot
Appointments are provide by physician referral. Physicians can schedule appointments by calling 1-877-688-6122.

32-Slice CT Scanning and Cardiac Scoring

A computer axial tomography (CAT), often referred to as CT scan utilizes the processes of two computers to generate a three-dimensional (3D) image from flat X-ray pictures, one slice at a time. CT scanners use highly complex programs to interpret the X-ray images, the X-ray images are then merged together - slice by slice, angle by angle - to create the 3-D image. CT scans can be used to obtain information about almost any body organ.

St. Joseph Mercy's CT Scanner provides advanced diagnostic testing for most diseases, because it provides high quality images utilizing very small slices that allow a radiologist to identify and interpret abnormalities that may otherwise have been missed with other technology. For example, it allows small cancers to be identified at a much earlier stage.

St. Joseph Mercy Hospital is home to a 32-slice CT scanner, with some of the most advanced capabilities. Your doctor may order this type of diagnostic imaging when there is a need to evaluate internal organs.

Cardiac Scoring

St. Joseph Mercy Hospital now offers Cardiac Scoring.

Coronary heart disease is the leading cause of death among American adults. Approximately 50 percent of individuals often exhibit no symptoms and feel healthy just prior to a heart attack. To help you understand your risk for heart attack, St. Joseph Mercy offers Cardiac Scoring. Cardiac Scoring accurately measures the amount of calcified plaque in the arteries providing you with the information necessary to develop a preemptive care plan with your physician.

Utilizing the advanced diagnostic capabilities of St. Joseph Mercy's 32-slice CT Scanning equipment, cardiac scoring provides for computer tomography in a noninvasive method to evaluate the potential for cardiac disease especially for those at high-risk for heart disease.

Heart scores are generally not covered by insurance. The cost of St. Joseph Mercy's comprehensive Cardiac Scoring service is $395, and includes:

  • Exam
  • Radiologist reading
  • Detailed cardiac scoring report, sent directly to the patient and his/her physician

No physician referral is necessary for Cardiac Scoring. To find out more, and to make your appointment, please call 810-985-1455.
