Unlabelled:
Improvements in ultrasound (US) resolution have led to the application of this non-ionizing imaging modality in the diagnosis of soft tissue disorders affecting the head and neck region. Although operator experience is paramount in image interpretation, US has the advantage of being inexpensive, safe and widely available. Ultrasound is the first line imaging modality for suspected salivary gland tumours and is useful in evaluating superficial neck swellings, such as lymph node disease, soft tissue cysts and vascular malformations. Ultrasound also improves the success rate when used for guidance during fine-needle aspiration cytology (FNAC).
Clinical Relevance:
This paper aims to provide the general practitioner with an overview of the basic principles of image formation, the advantages and disadvantages of US, and an outline of its indications for conditions that might present to the dental practitioner.

Ultrasound 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...
