Ultrasound

At the NRH ultrasound is performed by highly trained radiographers and the radiologist. Ultrasound uses high frequency sound waves to examine internal organs, joints, tendons and blood vessels. An ultrasound scan will not make you feel any different or have any adverse side effects. A small amount of warm gel is placed on the area of interest and with gentle pressure on the skin surface the examination is undertaken within a few minutes.

Please note that some ultrasound procedures require preparation – see below.

– Abdominal ultrasound – you must have nothing to eat for four hours before the appointment, but you may still drink water. Continue to take any prescribed medication.

– Abdomen and pelvis ultrasound – you must eat nothing for four hours before the appointment, but you may still drink water. You must drink half a litre (500mls) of water one hour before the scan – you must not empty your bladder.  Continue to take any prescribed medication.

– Kidneys, bladder and pelvis ultrasound – you must have a full bladder so please drink half a litre (500mls) of water one hour before your scan – you must not empty your bladder. Continue to eat normally and take any prescribed medication.

– Children – please encourage your child to drink plenty so that they have a full bladder when they arrive for the appointment. Continue to take any prescribed medication.

DXA 
DXA (Dual-Energy X-ray Absorptiometry) is a specialist X-Ray exam used to measure your bone strength or bone mineral density.  Osteoporosis is one of the conditions that can cause loss of bone mass.  Bones that are not very dense can become weak and are more likely to break.

Density measurements are taken of bones at specific areas of your body – usually at the lower back, hip, wrist or forearm.  The results show whether you have lost bone density. The measurements also help determine the presence of osteoporosis and can be used to estimate your risk of a possible bone fracture.  If you are being treated for bone loss, a follow-up exam can also show if the therapy is working.

There is little or no preparation for this exam. Please do not take any calcium supplements 24 hours before the exam.  Dress comfortably but try to avoid clothes with metal zips, buttons or belts.
