Abstract:
Peripheral nerve imaging is a powerful tool in evaluating peripheral neuropathy. This review aims to provide an overview of the anatomy, clinical significance and pathologies of small peripheral nerves, typically less than 2 mm in diameter. High frequency ultrasound probes offer the best assessment of these nerves whilst permitting real-time clinical correlation, while the role of MRI is inherently limited by spatial resolution constraints and the lack of patient contact. This review discusses techniques for sonographic identification, strategies for optimal visualization and common ultrasound-guided procedures.

01:20Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
