Ultrasound – General & Vascular

Ultrasound or sonography produces imaging using high-frequency sound waves. It is especially useful for examining the aorta, carotids, blood flow in the extremities, breasts, bladder, thyroid, kidneys and other abdominal organs for conditions such as abdominal aortic aneurysm, peripheral artery disease, congestive heart failure, thyroid disorder and acid reflux.

During the procedure, the patient is positioned on an examination table and a warm, clear gel is applied to the area being examined. A transducer is then firmly pressed against the skin and swept back and forth to obtain the image.


Magnetic Resonance Imaging (MRI)

MRI provides physicians with a non-invasive method of obtaining high quality images. It combines a powerful magnet with an advanced computer system and radio waves to produce accurate, detailed pictures of organs and tissues in order to diagnose a variety of medical conditions such as thyroid disorder, congestive heart failure, abdominal aortic aneurysm, peripheral artery disease and acid reflux.

Mason City Imaging offers High-field MRI, which produces a high quality image in the shortest time allowing for the most accurate diagnosis to be made.

Preparation Required

The patient should wear comfortable clothing such as sweatpants and sweatshirt without metal snaps or zippers. Gowns are available if needed. Hairpins should not be worn. No jewelry or watches should be worn into the scan room. It is best to leave your jewelry at home.

An MRI exam is safe, simple and painless. However, because some metal interferes with the MRI machine, the patient cannot be examined if they have: brain aneurysm clips, pacemaker or pacing wires, metal fragments in the eye, inner ear implants, or implanted spinal cord or brain stimulator. The patient may leave immediately following the exam because the MRI has no side effects.

Results of the test

The test will be interpreted promptly and results will be sent to the ordering physician who will share the results with the patient.


Computed Tomography (CT)

CT is a way of looking inside the body using a special camera that takes a complete 360-degree picture. It combines the latest X-ray technology with high-speed computers to capture images of fast-moving physical process. It can be used to diagnose peripheral artery disease, thyroid disorder, abdominal aortic aneurysm, congestive heart failure and acid reflux. The images produced are cross-sectional and show much greater detail than standard X-ray films. This greatly enhances the healthcare provider’s ability to diagnose a medical condition.

To make a clearer picture of certain parts of the body, some CT exams require the use of contrast material. Two types of contrast materials used are barium, which the patient usually drinks, and a non-ionic solution, which is usually injected by means of an IV.

Preparation Required

Patients will be asked to change into a gown for most procedures. Metal objects can affect the image, so clothing with zippers, snaps, etc. should be avoided. Patients may be asked to remove hairpins, jewelry, eyeglasses, hearing aids and any removable dental work that could obscure the images. Patients may be asked to refrain from eating or drinking anything for 3-4 hours before the exam. Their healthcare provider will give instructions specific to a patient’s particular exam to them. The patient may leave immediately following the test.

Results of the test

The test will be interpreted promptly and results will be sent to the ordering physician who will share the results with the patient.
