We believe our machines are currently the best in the world, and include all the very latest ultrasound technology. The scans are performed by a sonographer, directly supervised by a radiologist, or by a specialist radiologist or obstetrician trained in the use of ultrasound.  \nWHAT IS ULTRASOUND?  \nAn ultrasound scan is a diagnostic imaging procedure that uses a transducer to send out sound waves at hig frequency. When the transducer is placed at certain locations and angles, the sound waves move through the skin and other body tissues to the organs and structures within. The sound waves bounce off the organs and return to the transducer. The transducer picks up the reflected waves, which are then converted by a computer into an electronic picture of the organs or tissues under study. Dolphins and bats navigate their way around using sound waves in exactly the same way as ultrasound.  \nDifferent types of body tissues affect the speed at which sound waves travel. Sound travels the fastest through bone, and moves most slowly through air. The speed at which the sound waves are returned to the transducer, as well as how much of the sound wave returns, is translated into a picture.  \nUltrasound is used to view internal organs as they function (in ‘real time’), and to assess blood flow through vessels. Ultrasound procedures are used to examine many parts of the body such as the abdomen, breasts, female pelvis, prostate, scrotum, thyroid and parathyroid glands, and the vascular system. During pregnancy, ultrasound is performed to evaluate the development of the fetus.  \nTechnological advancements in the field of ultrasound allow images that can be made in a threedimensional view and/or ‘four-dimensional view’. The added fourth dimension of 4D is motion, so that it is a 3D view with movement, and these scans are predominantly used in obstetric scanning. It is used to enhance visualization of fetal abnormalities, picked up by conventional imaging, such as cleft lip, so that parents can recognize what the doctors are describing.  \nWHAT ARE THE DIFFERENT TYPES OF ULTRASOUND SCANS?  \nDifferent ultrasound techniques exist for different conditions. Examples of some of the more common types of ultrasound examinations include the following:  \n• Doppler ultrasound: Doppler ultrasound can determine if there are any problems within the veins and arteries by measuring the speed and direction of flowing blood.  \n• Vascular ultrasound: Used to see the vascular system and its function, including detection of blood clots.  \n• Abdominal ultrasound: Used to detect any abnormalities of the abdominal organs (i.e. kidneys, liver, pancreas, gallbladder), such as gallstones or tumours.  \n• Renal ultrasound: Used to examine the kidneys and urinary tract, particularly to investigate kidney pain or blood in the urine (haematuria) .  \n• Obstetric ultrasound: Used to monitor the development of the fetus and maternal wellbeing.  \n• Pelvic ultrasound: Used to scan the uterus, ovaries and/or bladder to help diagnose pelvic pain symptoms, for example.  \n• Breast ultrasound: Used to examine a mass in the breast tissue, and for surveillance in conjunction with mammography.  \nASTRA RADIOLOGY: ULTRASOUND  \nASCOT HOSPITAL: 90 Green Lane East, Remuera ASCOT CENTRAL: 7 Ellerslie Racecourse Drive, Remuera AUT MILLENNIUM: 17 Antares Place, Rosedale BIRTHCARE, PARNELL: 20 Titoki Street, Parnell HIGHLAND PARK: Level 1, 14 Highland Park Drive, Highland Park ST HELIERS: Level 1, 8-10 Turua Street, St Heliers FOR ALL BOOKINGS TEL: (09) 520 9550 EMAIL: [us@astraradiology.co. nz](us@astraradiology.co. nz www.astraradiology.co.nz)[ www.astraradiology.co.nz](us@astraradiology.co. nz www.astraradiology.co.nz)  \nUltrasound CONTINUED  \n• Thyroid ultrasound: Used to see the t","cbCaijYmOGnkqVgN","https://ap.wps.com/l/cbCaijYmOGnkqVgN","pdf",150962,"English","# What is ultrasound?\n## Different types of ultrasound scans\n## Astra Radiology: Ultrasound (clinic locations)\n## Before an ultrasound\n## During an ultrasound","[{\"question\":\"How does an ultrasound scan create an image?\",\"answer\":\"A transducer sends high-frequency sound waves into the body.
