Procedures

Ultrasound and CT Guided Injections

This procedure uses CT or ultrasound to find the correct area where the injection should be given. For example, it can be used to help in finding the joint or soft tissue into which a corticosteroid (steroid type medicine) or local anaesthetic needs to be injected to reduce inflammation and provide pain relief. This procedure is most often used in the shoulder, knee, hip and spine.
A radiologist will perform the examination.
Preparation
Depending on the type of examination you are having you may need some preparation. For some scans you will be asked to change into a gown. Bring diagnostic scans to assist with locating the treatment area. You may need to bring a driver to take you home after examination, as you will not be allowed to drive home yourself. If this is the case, we will let you know during the appointment process.
Pregnant?
It is important that you tell your own doctor and The Cross Radiology if there is any chance you might be pregnant. This is important information, as it will make a difference in the way the procedure is carried out or a different test altogether might be required. Your safety and that of your unborn child is the number one priority.
Upon Arrival
On arrival, you are required to complete a consent form, outlining your medical history and allergies.
During the Procedure
You may also be asked to remove your pins, chains or other items of jewellery before the examination, as these can sometimes interfere with examination. Although many injections are painless, a local anaesthetic may be given if needed. The whole test should take 10 to 40 minutes, depending on the area being injected. If local anaesthetic is given, you will feel numbness in the area for up to 2 hours. This will affect your mobility.
Results
Our experienced radiologist will specify what kind of procedure was performed and what medication was used. You will be asked to wait for this report after your procedure. If any pathology was taken, they will be sent to pathology for testing. These pathology results will be sent directly to your doctor in 2-3 working days.
Risks
There are no known risks with the use of ultrasound. There is a small risk of infection due to the open wound. The procedure can be repeated but no more than three or four times a year to avoid damage to the joints. This will be discussed with you if needed.

The dose of radiation used in a CT scan is generally small and rarely produces harmful effects. If you have many CT scans, there is a slight increase in the lifetime risk of cancer. The small potential risk is balanced against the benefits of picking up serious heart disease. The radiation dose will be kept as low as possible. There is also some risk related to contrast (see Iodinated contrast consumer information sheet).

Ultrasound Guided Biopsies

An ultrasound-guided biopsy (core or fine needle aspiration biopsy) uses sound waves to help locate a nodule or abnormality within the breast/thyroid/neck and remove a tissue sample for examination under a microscope. The procedure is less invasive than surgical biopsy, leaves little to no scarring and does not involve exposure to ionizing radiation.
Nodules or abnormalities in the body are often detected by imaging examinations. However, it is not always possible to tell from these imaging tests whether a nodule is benign (non-cancerous) or cancerous.
Ultrasound guided biopsy procedures are performed by a specially trained radiologist with experience in needle aspiration and ultrasound.
A radiologist will perform the examination.
Preparation
This procedure requires little to no special preparation. This will be conveyed to you during the appointment process. Tell your doctor about any medications you're taking, such as aspirin or blood thinners.

Bring diagnostic scans to assist with locating the treatment area.

Upon Arrival
On arrival, you are required to complete a consent form, outlining your medical history and allergies.

For some procedures, you may be asked to change into a gown. You may also be asked to remove your hairclips, earrings, pins, chains or other items of jewellery before the examination, as these can sometimes interfere with examination.
During the Procedure
The area to be biopsied will be checked and an area of skin will be cleaned with an antiseptic. You maybe give local anaesthetic to numb the skin and insert a needle to obtain some tissue. Several samples of tissue may be required.

The whole procedure should take 10 to 40 minutes, depending on the area being biopsied.

If local anaesthetic is given, you will feel numbness in the area for up to 2 hours. This will affect your mobility.
Results
The extracted tissue will be sent to pathology for study and the pathologist examines the removed specimen and makes a final diagnosis so that treatment planning can begin.

The results will be sent to your treating doctor to discuss with you. This usually takes 2 to 4 working days.
Risks
The doctor believes the benefits to you from having this procedure exceed the risks involved.

The risks and complications with this procedure can include but are not limited to the following.

Common risks and complications include:
- Pain or discomfort at the puncture site. This may require medication.
- Bleeding or bruising may occur. This is more common if you take Aspirin, Warfarin, Clopidogrel (Plavix and Iscover) or Dipyridamole (Persantin and Asasantin).
- Failure of local anaesthetic which may require a further injection of anaesthetic or a different method of anaesthesia may be used.
- Nerve damage, is usually temporary, and should get better over a period of time. Permanent nerve damage is rare.

Less common risks and complications include:
- Infection, requiring antibiotics and further treatment.
- Damage to surrounding structures such as blood vessels, organs and muscles, requiring further treatment.
- Excessive bleeding from the puncture site. This may require other treatment and/or corrective surgery.
- An allergy to injected drugs, requiring further treatment.
- (Breast biopsies only) Pneumothorax, a collection of air around the lining of the lungs. This usually stops by itself but sometimes may require a tube to be inserted into the chest.
- The biopsy procedure may not obtain enough tissue and may need to be repeated at a later date.
- The procedure may not be possible due to medical and/or technical reasons.

Rare risks and complications include:
- Seizures and/or cardiac arrest due to local anaesthetic toxicity.
- Death as a result of this procedure is very rare.

Epidural/Nerve Root Injections

This is an injection of local anaesthetic and steroid (anti-inflammatory medication) drugs close to the nerves of the back or the epidural space in the spine. Conditions such as degenerative arthritis or disc prolapse can cause pain. The injection your doctor has requested is intended to relieve pain by reducing inflammation allowing increased mobility.
A radiologist will perform the examination.
Preparation
Bring diagnostic scans to assist with locating the treatment area.

Bring a driver to take you home after examination, as you will not be allowed to drive home yourself.
Pregnant?
It is important that you tell your own doctor and staff at the radiology facility where you are having the CT if there is any chance you might be pregnant. This is important information, as it will make a difference in the way the CT is carried out or a different test altogether might be required. Your safety and that of your unborn child is the number one priority.
Upon Arrival
On arrival, you are required to complete a consent form.

Please let us know if you take blood-thinning medication for example Aspirin, Warfarin, Debigatran or Clopidogrel, or if you have any allergies.

You will be required to change into a gown.

You may also be asked to remove your pins, chains or other items of jewellery before the examination, as these can sometimes interfere with examination.
During the Procedure
You will lie face down on the CT examination table. The procedure is performed under sterile conditions with the skin in the area to be injected cleansed. CT imaging is used to accurately locate the area to be injected and to guide the needle. The whole test should take 20 to 30 minutes.

You may experience some soreness or bruising at the needle site and, rarely, minor muscle spasm. You may also experience temporary numbness in the area for up to 2 hours due to the extra pressure of the injection solution in you facet joint. This will affect your mobility.
Risks
The dose of radiation used in a CT scan is generally small and rarely produces harmful effects. If you have many CT scans, there is a slight increase in the lifetime risk of cancer. The small potential risk is balanced against the benefits of picking up serious injury or disease. The radiation dose will be kept as low as possible, especially if you are pregnant or very young. If you had the contrast, there is also some risk related to this (see Iodinated contrast consumer information sheet).

Facet Joint Injections

The facet joints are the articulations between vertebral bodies that allow the vertebral column (spine) to move. Conditions such as degenerative arthritis and inflammation of the facet joints can cause pain.
The injection your doctor has requested is a mixture of local anaesthetic and steroid (an anti-inflammatory medication). The injection is intended to relieve pain by decreasing facet joint nerve activity and reduce inflammation allowing increased mobility.
A radiologist will perform the examination.
Preparation
Bring diagnostic scans to assist with locating the treatment area.

Bring a driver to take you home after examination, as you will not be allowed to drive home yourself.
