ultrasoundcarotid.jpgWhat is an ultrasound?
An ultrasound is a medical imaging test that uses high frequency sound waves to produce real-time images of internal organs or blood vessels.  An ultrasound works by placing a gel on the body and then moving an instrument called a transducer over the area to be examined.  The transducer emits sound waves that reflect off of body parts at differing rates, producing images of the internal structures of the body. 

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: It is very important not to eat or drink anything for 4 hours prior to your exam. This ensures optimal visualization of the upper abdominal organs.

Approx. length of exam: 30 minutes





Arterial Duplex
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

Approx. length of exam: 30 minutes-45 minutes





Carotid Duplex
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

Approx. 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; For transvaginal pelvic ultrasound – arrive with an empty bladder

Approx. length of exam: 30 minutes

 




Renal Ultrasound
This exam studies both kidneys and the urinary bladder. 
Patient Prep:  Arrive with a full bladder

Approx. 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 or drink for 8 hours prior to exam.

Approx. 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

Approx. length of exam: 30 minutes





Venous Duplex
This exam interrogates the deep veins in the arms or legs by using the transducer to gently press on the veins, looking for compressability.  Duplex is used to assess for appropriate venous flow.
Patient Prep:  There is no prep for this exam

Approx. length of exam: 30 minutes





Ultrasound is also used for guidance in many biopsy procedures, such as:


Fine Needle Aspiration (FNA)
This procedure is typically done to sample nodules of the thyroid or other superficial structures.  This is a very simple outpatient procedure performed by a radiologist.
Patient Prep: No blood thinners or aspirin x 5 days

Approx. length of exam: 1 ½ - 2 hours





Liver Biopsy
Ultrasound guidance is used by a radiologist to place a needle into an area of the liver where a small sample is taken by a biopsy device.  Patients will start in our Radiology Care Unit as well as recover there after the procedure, under the care of our Radiology Care Nursing Staff.
Patient Prep: No blood thinners or aspirin x 5 days; nothing to eat or drink after midnight

Approx. length of exam:  1 hour of pre-bx workup by nursing staff; followed by 30 minutes for the actual biopsy; then 30 minutes to 1 hour of observation/ recovery time with nursing staff      



       
              
Paracentesis
This procedure is done to drain fluid from the peritoneal cavity of the abdomen.  Ultrasound guidance is used by the radiologist to place a catheter into a safe pocket of fluid. This is an outpatient procedure, only  local anesthetic is used. 
Patient Prep: No blood thinners or aspirin x 5 days. 

Approx. length of exam: highly dependent on the amount of fluid to be drained, but typically will take 1-2 hours.
