CT scan (computerized tomography)


CT scan is usually done to diagnose an infection, identify masses and tumors, and helps study blood vessels. It also guides a surgeon to the right area during a biopsy.

During this test, the patient lies in a doughnut-shaped machine that takes pictures of the body. The scanner is used in combination with a digital computer to create "slices" of different organs of the body, making it possible to detect diseases sooner than with a regular X-ray.  

To prepare for a CT scan:

Wear loose, comfortable clothing free of metal snaps and zippers, if possible. When you arrive, you will be asked to remove metallic jewelry, watches, hair pins, hearing aids, removable dental work and glasses if they are in the area being scanned.
If you are having a CT scan of the abdominal area, you may need to drink a liquid contrast. This will be given to you, with instruction, in advance. You may be asked to not eat or drink anything for four hours before your scan. Your health care provider will instruct you which medications, if any, cannot be taken.

The scan typically takes 30 minutes or less. You will be asked to hold very still in specific positions as instructed by a technologist. You may be asked to hold your breath during some scans to reduce blurring on the images. If your scan requires the use of a contrast, you may be given another contrast material during the scan by IV injection. This may make you feel warm inside, but the sensation only lasts a few moments and is not painful. After the scan, you will be asked to drink plenty of fluids. 

Spot the early stages of heart disease with a heart calcium scoring test.

Heart calcium scoring

Heart calcium scoring is an easy and powerful way to spot the early stages of heart disease while there's still time to stop it. It's a simple exam that can detect years of plaque build-up long before you have symptoms of heart disease. This potentially life-saving test only takes 15 minutes. 

The test is performed with a cardiac CT scan to identify the presence, location and amount of calcified plaque in the coronary arteries. Calcified plaque can signal the presence of atherosclerosis, a disease of the vessel wall known as coronary artery disease. People with this disease have an increased risk for heart attack. 

In general, men over the age of 30 and women over the age of 40 should consider having a heart calcium scoring. Anyone with the following risk factors should also consider heart calcium scoring:

  • High cholesterol levels
  • Family history of heart disease
  • Diabetes 
  • High blood pressure
  • Cigarette smoking
  • Overweight or obese
  • Physically inactive

A doctor’s referral is necessary to have this test. The cost for heart calcium scoring is $49.95.

MRI (magnetic resonance imaging)


An MRI is a non-invasive and painless procedure in which radio waves and powerful magnets linked to a computer are used to create remarkably clear and detailed pictures. MRI scanners are well suited to image the non-bony parts or soft tissues of the body. It is often used for disease detection, diagnosis and treatment monitoring. The brain, spinal cord and nerves, as well as muscles, ligaments, and tendons are seen much more clearly with MRI than with regular X-ray and CT; for this reason MRI is often used to image knee and shoulder injuries.

To prepare for an MRI:

For your safety, you will be asked to put on a patient gown for the test. Clothing with metal or pockets will not be allowed in the scanning room. Certain types of metal in the area being scanned can cause significant errors, called artifacts, in the images. It is important that metal objects are not brought into the scanning room. You will be asked to remove your jewelry, watch, hairpins, bobby pins and hearing aids. A typical exam lasts between 30 to 60 minutes for each body area being scanned. You should allow extra time because the exam may last longer than expected. 

The magnet makes a “knocking” sound as images are being taken. In between scans, the machine is quiet. The MRI technologist will provide you with either ear plugs or headphones for you to listen to music during your exam.

Interventional Radiology 

Interventional radiology uses imaging such as CT, ultrasound and X-ray to help guide minimally invasive procedures such as inserting catheters, wires, and other small instruments and tools into your body. Doctors use this technology to diagnose or treat conditions instead of using a scope (camera) or with surgery. Interventional radiologists are often involved in treating cancers or tumors, blockages in the arteries and veins, fibroids in the uterus, back pain, liver problems and kidney problems.

Interventional procedures often carry less risk, require smaller incisions and take less recovery time than surgery. These procedures are done by board-certified radiologists, doctors with advanced training in minimally invasive treatments that use imaging guidance. Preparation for this scan varies by patient based on the test being conducted. To learn more, visit Green Bay Radiology.

Nuclear Medicine


 Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of, or treat, a variety of diseases, including cancers, heart disease, gastrointestinal, endocrine, skeletal and other abnormalities within the body.
With ordinary X-ray, an image is created by passing X-rays through the body. In contrast, nuclear medicine procedures use a radioactive material, called a radiopharmaceutical or radiotracer, which is injected into the bloodstream, swallowed or inhaled as a gas. This radioactive material accumulates in the organ or area of the body being examined, where it gives off a small amount of energy in the form of gamma rays. Special cameras detect this energy and produce detailed pictures on both the structure and function of organs and tissues in the body.

Scanning can begin immediately after injection, or be delayed for several hours or even days. Scan time also varies, with some scans as short as 30 minutes and others several hours. Preparation for nuclear medicine exams varies, so instructions should be reviewed and followed carefully for each exam.



Ultrasound is a type of imaging that uses high-frequency sound waves to look at organs and structures inside your body. It serves many purposes such as viewing a baby during pregnancy, helping to diagnose a variety of conditions, helping to assess organ damage following an illness, and it is used to help evaluate symptoms such as pain, swelling and infection. Ultrasound is also used to guide procedures such as needle biopsies.

During an ultrasound, you lie on an examination table and a clear gel is applied to the areas of the body being studied. This helps the transducer make firm contact with your body. It is then moved back and forth over the area of interest and uses high frequency sound waves to obtain images. 


X-ray, commonly referred to as radiography, uses ionizing radiation to provide images of the body. Radiography is used in many ways to diagnose disease and injuries. Some common exams are X-rays, GI fluoroscopy exams and joint injections (arthrograms). Preparation for this scan varies by patient based on the test being conducted.
