Ultrasound scanning uses high frequency sound waves to create images. The scans are performed by a sonographer, directly supervised by a radiologist, or by a specialist radiologist trained in the use of ultrasound.
The improved resolution of the very high frequency probes and ultrasound software has led to better visualisation of soft tissues. This is particularly illustrated in musculoskeletal imaging. Structures, such as the tendons at the shoulder and ankle, are now visualised and ultrasound can, therefore, evaluate sporting injuries and 'wear and tear' on ligaments and tendons.
Doppler ultrasound is based on the change in frequency of sound caused when it is reflected from moving blood cells. With colour doppler ultrasound, the information is colour-coded for velocity and direction, allowing a more graphic assessment of flow. Recently Power Angio imaging has become available and this allows assessment of slower flow situations compared with colour doppler ultrasound. Doppler is useful for quantifying blood flow and severity of stenosis, for example, in the assessment of the carotid arteries.
Tissue Harmonic Imaging is a relatively new technique which significantly increases contrast resolution in ultrasound by reducing image artifact, haze and clutter. It improves 2D imaging and can help salvage examinations initially deemed undiagnostic.
Compound imaging is another new technique and is used on most new generation ultrasound machines to remarkably increase resolution from conventional imaging methods.
The latest techniques in ultrasound are 3D and 4D imaging (0.6MB PDF). These techniques provide expectant parents with very realistic surface rendered images of fetal faces and bodies.
Ascot Radiology has three state-of-the-art ultrasound machines: an IU22, manufactured by Philips, and a Voluson and E8, both from GE. We believe our three machines are currently the best in the world, and include all the technology mentioned above.
Ascot Radiology also offers high quality paper prints (18x24cm), CDs, DVDs and video copies of the scan when required.
OBSTETRIC ULTRASOUND
At Ascot Radiology we are specialized in the area of obstetrics and gynaecology and are lucky enough to have many experts in the field working in conjunction with highly trained and experienced sonographers. We aim to provide expert scanning and counseling through all stages of your pregnancy.
Nuchal fold screening:
We are accredited in use the world renowned and respected Fetal Medicine Foundation screening programme from London. All of our sonographers/sonologists have been extensively trained and examined in nuchal measurements and nasal bone assessment to gain accreditation.
Fetal anatomy scanning (18-20weeks):
We give 1/2 hour appointment times for these scans so that they are not rushed. A thorough explanation during the scan, with a consultation from a specialist is also provided. There is also an option to include a short 4D scan and a printed 3D image, if pre-booked.
Echocardiography:
A detailed scan of fetal hearts done at 25-28 weeks for suspected heart abnormality.
3rd Trimester assessments:
including Doppler, biophysical profiles, and growth scans.
Amniocentesis and Chorionic Villus Sampling (CVS):
interventional procedures for chromosomal abnormality. For more information on either Amniocentesis or Chorionic Villus Sampling, please click on the Nuchal Assessment link below.
Obstetric Ultrasound Prices:

Routine scans (including Nuchal & 18 week anatomy scans): $60
DVD/CD of scan: $25
Printed image (18 x 24 cms): $10
2D package (including scan, DVD, e-mail images and a printed image): $130
4D package (as above and including a 5 minute 4D video and a 3D printed image): $180 Maternal request: 4D package (as above): $190
Vascular Scanning: veins and arteries of the abdomen and limbs. For example, carotid Doppler, renal artery assessment, and varicous vein mappings etc
Our state of the art equipment and highly trained staff mean we can provide our clients with a very high standard examination in all of these areas.
In Radiology today, many radiologists sub-specialise within their field. Our booking staff are experienced in making appointments with the best specialist to be involved in the study.
All of our specialists at Ascot Radiology also work within the public health system and because of this, have a wealth of experience in their own areas.
INTERVENTIONAL ULTRASOUND
It is very commonplace today to use radiology for interventional procedures to avoid surgery. We are very fortunate to have a highly experienced team of interventional radiologists working at Ascot Radiology to perform the following procedures;
Fine needle biopsies
Core samples
Renal biopsies
Nephrostomies
Breast biopsies and hookwires
Amniocentesis and CVS in pregnancy
Levovist hysterosalpingograms: to look at the fallopian tubes
Aspriations: of cysts and collections, for example
Sonosaline hysterography: to look at uterine cavity
If you require any of the above examinations, or have any questions regarding these procedures, we employ a full-time staff nurse within Ascot Radiology and she would be happy to help you.
