• Ultrasound

  • Ultrasound St. Catherine Hospital Kansas Ultrasound produces images using high-frequency sound waves rather than x-rays. Sound waves are directed into the body from a transducer through the skin surface. When these sound waves come into contact with the internal structures, part of the sound energy is reflected back to the body surface, to the transducer where it is converted electronically into an image.

    It is used to evaluate numerous structures such as the gall, bladder, spleen, liver, kidneys, breast, heart, and thyroid.

    Doppler Ultrasound detects blood flow in the veins and arteries and is used to evaluate and diagnose problems such as blood clots and atherosclerotic disease. These same techniques are used to evaluate the heart at rest and for a stress echocardiogram.

    Common ultrasound tests that may be ordered by your provider include:

    • Abdominal Ultrasound: This exam includes imaging of the liver, gallbladder, bile ducts, kidneys, spleen, pancreas, aorta, and IVC. This exam is generally ordered for abdominal pain or abnormal blood work results.
      Patient Prep: I t is very important not to eat or drink anything for 8 hours prior to your exam. This ensures optimal visualization of the upper abdominal organs.
      Approximate length of exam : 30 minutes
    • Arterial Doppler : This exam is generally performed on the arteries in the legs or arms. It is used to assess the speed, direction, and pattern of flow in the arteries. Any areas of plaque, stenosis, or aneurysm will also be documented.
      Patient Prep: There is no prep for this exam
      Approximate length of exam : 30 minutes-45 minutes
    • Carotid Doppler: This exam is used to assess the carotid arteries in the neck, which help supply blood flow to the brain. It is used to assess the speed, direction, and pattern of flow in the arteries. Any areas of plaque, stenosis, or aneurysm will also be documented. This exam can be ordered when a patient is experiencing stroke like symptoms, dizziness, headache, or before certain surgeries as a pre-op workup.
      Patient Prep: There is no prep for this exam
      Approximate length of exam : 30 minutes
    • Pelvic Ultrasound : This exam assesses the uterus, ovaries, and surrounding pelvic structures. Most often an internal, transvaginal transducer is used for optimal visualization of these structures.
      Patient Prep: For transabdominal pelvic ultrasound- arrive with a full bladder
      Approximate length of exam : 30 minutes
    • Renal Ultrasound: This exam studies both kidneys and the urinary bladder.
      Patient Prep: Arrive with a full bladder
      Approximate length of exam : 30 minutes
    • Renal Doppler: This exam studies both kidneys, the urinary bladder, and the blood vessels that supply blood and drain blood from the kidneys.
      Patient Prep: Nothing to eat for 8 hours. Arrive with a full bladder.
      Approximate length of exam : 60 minutes
    • Thyroid/ Neck Ultrasound: This exam is performed on the thyroid and/or surrounding structures to look for any abnormalities.
      Patient Prep: There is no prep for this exam
      Approximate length of exam : 30 minutes
    • Venous Doppler: This exam interrogates the deep veins in the arms or legs by using the transducer to gently press on the veins, looking for compressibility. Duplex is used to assess for appropriate venous flow.
      Patient Prep: There is no prep for this exam
      Approximate length of exam : 30 minutes
    • Obstetrical Ultrasound: This exam evaluates the size and age of a fetus and assesses its growth, development and well-being during pregnancy. Fetal ultrasound can be used to detect some, but not all, fetal abnormalities. This screening allows appropriate treatment to be given during pregnancy and childbirth.
      Patient Prep: Full bladder
      Approximate length of exam : 30 minutes
    • Aorta Ultrasound: This exam evaluates the main artery that travels through your abdomen and delivers blood to all vital organs. It is used to assess the speed, direction, and pattern of flow in the aorta. Any areas of plaques, stenosis, or aneurysm will also be documented.
      Patient Prep: Nothing to eat or drink for 8 hours prior to exam
      Approximate length of exam : 30 minutes
    • Echocardiogram: This test is used to look at how blood flows through the heart chambers, heart valves, and blood vessels by placing the transducer on various locations of your chest or abdominal wall. This test is done to look for the cause of abnormal heart sounds (murmurs), an enlarged heart, unexplained chest pains, shortness of breath, or irregular heartbeats.
      Patient Prep: There is no prep for this exam
      Approximate length of exam: 60 minutes
    • Testicular Ultrasound: This test is used to evaluate the size, texture and blood flow of the testicles and contents of the scrotum.
      Patient Prep : There is no prep for this exam.
      Approximate length of exam : 30 minutes
    • Ultrasound Guided Biopsy: The goal of a biopsy is to remove a sample of tissue for testing in a laboratory. A biopsy can help diagnose abnormalities such as infection, inflammation or malignancy. During your biopsy, an imaging physician will use an ultrasound scanner to accurately guide a needle to the site of the biopsy. The needle will then be used to remove a tissue sample.
      Patient Prep : Please discuss this with your physician prior to the exam.
      Approximate length of exam : 45-60 minutes
    • Venous Insufficiency Doppler: This test includes a venous Doppler exam as well as evaluates the superficial veins for incompetence. It also looks for varicose veins and communicating veins.
      Patient Prep : There is no prep for this exam.
      Approximate Length of exam : 1-1.5 hours
    • Breast: This test shows all areas of the breast including the area closest to the chest wall. It is used to see whether a breast lump is filled with fluid (a cyst) or if it is a solid lump. This may be done after an abnormal mammogram or if the patient is feeling a lump or pain.
      Patient Prep: There is no prep for this exam.
      Approximate length of exam : 30 minutes

     After your test, an experienced radiologist will analyze your ultrasounds and send a report to your referring physician who will inform you on your test results.
