Imaging Services at Parkwest

Our Imaging Services departments provide patients with high quality diagnostic and interventional services. Utilizing state-of-the-art technology our skilled technologists and nurses assist radiologists in providing excellence in patient care.

Our primary goal for Imaging Services is to assist physicians and other healthcare members in the diagnosis and therapy of patient’s disease through the use of radiography, radioisotopes, radio frequency and magnetic fields. All services are offered 24 hours 7 days a week. Specific outpatient times are listed for each modality.

Imaging

The following four principles represent the philosophy of Imaging Services:

  1. Provide imaging services as accurately, safely, and expeditiously as possible. Always be aware of radiation protection and minimization of patient exposure.
  2. Always be aware of radiation protection and minimization of patient exposure.
  3. Maintain open lines of communication between, patients, family, physicians, employees, and the general public in order to promote the well being of the public we serve.
  4. Treat all individuals with respect, dignity, and kindness at all times.

CT Scans

CT scans (computed tomography scans) were originally developed in the 1970s. A CT scan combines the power of X-ray technology and computerized imagery to take layered pictures of hard and soft tissues, including organs and bones. Approximately 2700 scans are performed monthly at Parkwest. All Technologists are ARRT registered.

Three scanners are in operation at Parkwest: Siemens Force-Dual Source CT scanner, a Siemens Drive-Dual Source CT scanner, and a GE 64-slice VCT (Volume Computed Tomography) scanner.

Exam Information

Patients are encouraged to wear comfortable clothing with minimal jewelry and metal. Some exams may require removal of earrings, necklaces, hair pins, dentures, partials, etc. to ensure quality images.

Always inform the technologist or RN if you are pregnant or may be pregnant.

Upon arrival, patients will be registered and escorted to the Out-patient waiting area.  If Lab work is required, this will be completed prior to the CT exam. A technologist or RN will explain the procedure prior to the exam and answer questions.

Oral and/or IV contrast may be required for the CT exam. If so, our experienced Technologists or RN’s will instruct the patient to drink the oral contrast and/or will start an IV line to administer the contrast. Preparation time varies depending upon the exam.

  • IV contrast is used to enhance the organs and vessels.
  • Oral contrast is used to differentiate the stomach, small bowel, and colon.
  • For many patient 40 oz. of water is used as the oral contrast depending upon how your physician ordered the scan.

Most exams take less then 10 minutes to complete and require minimal preparation. Exams requiring additional time and preparation are as follows:

CT Abdomen/Pelvis: For patients requiring oral contrast, no food or drink for 4 hours prior to the exam.

Biopsies and Drainages: Patients are required to report to the hospital 2 hours prior to their exam. After registration is complete, the patient is taken to Radiology Holding Room for preparation of the exam, i.e. medical history, IV line started if required, site preparation, etc. Patients requiring sedation or having an invasive procedure must have a driver to take them home. Patients on blood thinners may be required to stop taking the medication prior to the exam. Consult your physician or call Imaging Services before stopping any medication.

If your physician requests copies of your exam, a CD will be provided prior to your discharge.

Diagnostic Imaging (X-Ray)

X-Rays are a type of radiation called electromagnetic waves. X-Ray imaging creates pictures of the inside of your body.In the hospital setting, X-Rays are emitted by a machine as individual particles that pass through the body and then get detected. Radiation protection and minimization of patient exposure is always considered for patient safety. All Technologists are ARRT registered.

Exam Information

Patients are encouraged to wear comfortable clothing with minimal jewelry and metal. Some exams may require removal of earrings, necklaces, hair pins, dentures, partials, etc., to ensure quality images.

Always inform the Technologist or RN if you are pregnant or may be pregnant.

A technologist or RN  will call the patient the day prior to the exam to further explain the exam, as well as any preparation needed.

For some exams, patients may be required to drink barium and will be encouraged to drink plenty of fluids post procedure. Some exams may also require patients to be NPO (nothing by mouth-including water). If you are unsure please contact the Imaging Department.

Patients on blood thinners may be required to stop taking the medication prior to the exam. Consult your physician or call Imaging Services before stopping any medication.

If your physician requests copies of your exam, a CD will be provided prior to your discharge.

MRI Scans

MRI at Parkwest is an American College of Radiology Accredited (ACR) facility and features both a a 3 Tesla Siemens Magnetom Vida and a 1.5 Tesla Siemens Magnetom Sola. Both systems are 70 cm bore size which complies with bariatric accommodations. Table weight limit is 550lbs.

MRI (Magnetic Resonance Imaging) is a non-invasive procedure that uses powerful magnets and radio waves to create detailed images of the body. Unlike conventional radiography and CT, no radiation is used. All Technologists are ARRT registered with advanced registry in MRI.

Exam Information

A technologist or tech aide will call the patient the day prior to the exam. During this call the staff representative questions patients about metal implants, pacemakers, etc., and will address any questions. Patients are encouraged to wear comfortable clothing, but will be required to change into a gown prior to the start of the study. 

Upon registration, patients will be escorted to our outpatient waiting area. A technologist or tech aide will explain the procedure prior to the exam, review the medical history form and ask safety questions about metal implants, pacemakers, etc.

Because of the strong magnets, certain metal objects are not allowed into the room:

  • Items such as jewelry, watches, credit cards and hearing aids can be damaged.
  • Hair pins, safety pins, metal zippers and similar objects.
  • Removable dental work should be taken out prior to the exam.
  • Pens, pocket knives, and belts can be dangerous projectiles and should not be taken into the magnet room.

MRI also should not be used for people with metal objects in their bodies, such as:

  • Some pacemakers, defibrillators, and neurostimulators
  • Some brain aneurysm clips
  • Some artificial heart valves
  • Inner ear (cochlear) implants

In addition to the above, Lululemon, a popular ath-leisure brand, has been found to have metal fibers in the clothing. It is important that patients change into a gown to be safe.

Patients who are claustrophobic may have difficulty completing the exam. Ear plugs will be provided for the patient due to the loud noises generated from the MRI during normal operation. Exam time may be 30 minutes or greater. Some procedures require IV contrast after the initial exam. A technologist or RN will start your IV line so the contrast can be injected and the second phase of the scan will be completed.

If your physician requests copies of your exam, a CD will be provided prior to your discharge.

Nuclear Medicine

Nuclear Medicine specializes in medical imaging of an organ’s metabolic function. The procedure requires a radioactive isotope which is either injected through an IV line (INT) or administered orally into the body. Small amounts of radiation is then detected through one of the following cameras for interpretation: GE Ventri, GE MPR, GE Infinia, or a Siemens Evo. All Technologists are NMTCB certified.
