Dr. Grobbelaar has practiced solely in ultrasound since 1995, bringing decades of experience to diagnostic imaging in Hermanus.
Medical degree completed at the University of Pretoria.
Completed ultrasound training at Steve Biko Pretoria Academic Hospital.
Began her practice in Pretoria at Eugene Marais Hospital.
Moved to Hermanus Mediclinic, where she has practiced in ultrasound ever since.
Ultrasound is a safe, painless imaging technique that uses sound waves to produce detailed images of the inside of the body.
The imaging, also called ultrasound scanning or sonography, involves the use of a transducer (probe) & specialised sound conducting gel placed directly on the skin.
When Ultrasound Can Help
The following situations can benefit from an ultrasound examination.
We use inaudible sound (frequencies between 2–18MHz) to examine and scan organs, joints
and blood vessels.
Sound waves are transmitted into the body using a transducer (probe) placed against the skin.
The sound waves travel through the body and are reflected back when they encounter different tissues and structures.
The transducer receives these returning sound waves and converts them into electrical
signals.
A computer processes these signals to create a real-time image of the structures being
examined.
Directional Doppler is used to measure the velocity and direction
of blood flow, making it useful
in examinations of the heart and
blood vessels.
Measures the velocity and direction of blood flow and is useful in heart and blood vessel examinations.

Picks up very low and slow flow and can be used to assess perfusion.
When the wall of the main blood vessel weakens, mainly due to atherosclerosis, the vessel can begin to dilate.
In addition, ultrasound allows the abdominal aorta to be measured and
monitored, helping us
follow its diameter changes.
When the aorta dilates above 3 cm in diameter, patients are followed up yearly to monitor
its growth.
When the aorta dilates more than 4.5 cm, patients are then referred to vascular surgeons for consideration of a stent.
Monitoring the diameter of the abdominal aorta helps identify changes that may require further assessment.
When patients experience blackouts, dizzy spells,
strokes or temporary loss of consciousness, we examine
the carotid arteries to assess the vessel walls and
blood flow.
The 2D image allows us to look for
calcification, plaque, narrowing
or thickening of the vessel lining, while Doppler
assesses the movement of blood
through the arteries.
