Please arrive on time for your appointment or your appointment may have to be rescheduled. We do our best to keep to scheduled appointment times. Renal aortic ultrasound is available at our rooms in:įor further information please phone The Heart Group 623 6377 Where possible please take a ten minute walk prior to your appointment. You can continue to drink water ONLY as normal. Please do not eat for 4 hours before your appointment. This will be forwarded to your cardiologist who will send a report to you and your doctor with the results and a plan for management. The images are displayed on the screen and stored for later analysis. Our sonographer will apply a water based gel to the skin over the stomach and kidney area applying light to medium pressure to obtain images. The examination will take approximately 60 minutes. A Renal Doppler Ultrasound Scan is one of the most accurate ways to evaluate the blood flow to the arteries in the kidney to check the indication of any. You will need to lie flat on an examination couch. It is not invasive and does not involve radiation exposure. Ultrasound Left intrarenal Doppler examination shows a normal arterial curve with sharp systolic peak and resistance index <0.70 Intrarenal Doppler examination reveals a low resistance index (0.52) in the right kidney with flattened arterial curves ( parvus tardus ), suggestive for renal artery stenosis by the indirect method. The test uses ultrasound to image the kidneys and part of the abdomen. A renal artery ultrasound is a non-invasive imaging procedure that uses sound waves to create images of the renal arteries. Narrowing of the renal arteries leads to a reduction in blood supply to the kidney and is a significant and often treatable cause of high blood pressure. The renal arteries, that supply blood to the kidneys, can be narrowed either by atherosclerosis (cholesterol deposits in the artery wall) or fibromuscular dysplasia (a beaded overgrowth of the normal lining of the artery seen mainly in young people). Transcatheter Aortic Valve Implantation (TAVI).Electrophysiology Study with Catheter Ablation.Catheter Ablation for Atrial Fibrillation, also known as Pulmonary Vein Isolation Ablation.Coronary Angiography and Percutaneous Coronary Intervention (PCI).Cardiovascular Magnetic Resonance Imaging (Cardiac MRI).Coronary angiography and percutaneous coronary intervention (PCI).Ambulatory Blood Pressure Monitoring (ABU).The images show the direction and speed of blood as it flows through your arteries or veins. Agitated Saline Contrast Study (Bubble Study) Overview What is a Doppler ultrasound A Doppler ultrasound uses sound waves to produce images of blood moving through your circulatory system.The radiologists may sometimes speak to you in person during your examination. The images are looked at by a radiologist who will provide a written report for your doctor. During the use of the Doppler, you may hear whooshing noises which are a representation of the blood flow or pulse. The Doppler allows assessment of aspects of blood flow. During this procedure, it is common to use a form of ultrasound called Doppler. Measurements will be taken along the length of the vessels. During the scan, you will be asked to hold your breath and move into certain positions to allow a clear view of the aorta and associated vessels. ![]() ![]() The ultrasound probe is moved over the skin surface to see the structures below. First, a clear gel is applied to the skin over the area to be examined. Your examination will be performed by a sonographer who will introduce themselves, confirm your identity and the examination you are having done. However, ultrasound can provide benefit to patients who are very young, allergic to contrast or have poor kidney function as it does not require the use of contrast (“x-ray dye”) and does not use ionising radiation. Usually, other imaging is used to assess these structures, including CT, MRI and Angiography. Disruption of blood flow in these vessels can cause issues including hypertension, changes to kidney function, pain, and ischaemic effects (restricted blood flow causing a shortage of oxygen) on organs. The main vessels examined are renal arteries, celiac axis and SMA (Superior Mesenteric Artery).
