The Finger Ultrasound is a non-invasive diagnostic exam that captures images of the anatomical structures of the finger and discovers any abnormalities in the imaged area. An ultrasound is a very safe and reliable diagnostic imaging resource that assesses pathology and guides physicians towards your individualized treatment plan.
The following is a non-exhaustive list of information that a diagnostic finger ultrasound can provide:
- Acute injury to the fingers (including strains, tears or ruptures)
- Vascular abnormalities
- Nerves (ie. median nerve, ulnar nerve)
- Complex regional pain syndrome
- Finger clubbing
- Dupuytren’s contracture
- Trigger finger
If you have any signs or symptoms of pain in the finger region, such as discomfort, pain, swelling, numbness, tingling, or burning sensations, and want to get a diagnostic ultrasound, a referral from a general practitioner or family doctor is required for this exam.
HOW DO I PREPARE FOR A FINGER ULTRASOUND APPOINTMENT?
There are no specific preparations necessary for the finger ultrasound but your doctor may provide you with specific instructions. Dress in clothes that allow for easy access to examine the finger, otherwise, a medical gown will be provided.
A water-based gel is used to improve the transmission of the ultrasound waves. However, if you have any allergies to gel it is important to let the ultrasound technician know before the examination. In addition, please let the ultrasound technician know if you have had any previous surgery around the imaged area.
If you are pregnant or suspect that you may be pregnant, please notify your doctor. If you have any questions or concerns about preparing for your ultrasound, please discuss these with your physician before your appointment.
WHAT SHOULD I EXPECT DURING A FINGER ULTRASOUND APPOINTMENT?
Upon arrival, you will be shown to a private room. You will be asked to remove any jewelry that may interfere with the ultrasound procedure. When ready, the ultrasound technician will apply a small amount of a water-based gel to the transducer head and gently move it along your finger with mild to moderate pressure to capture clear images. The technician may ask you to change positions in order to capture all necessary images. Once finished, you will be able to wipe off the gel.
The assessment is approximately 15 minutes long for one finger and 30 minutes for more than one finger.
Shortly after your appointment, a radiologist will review your images and send a report to your general practitioner or family physician. Once the report is reviewed, your doctor will contact you with the results.
