Abstract:
The use of thoracic ultrasound as a diagnostic tool in the emergency department, intensive care unit or in patients with pulmonary diseases is increasing steadily. It is used to guide percutaneous tracheostomies, to assess pleural effusions, to rule out pneumothorax, and to guide the placement of endovascular and pleural catheters. It is also useful in the assessment of patients with dyspnea. The aim of this review is to provide the practical and technical basics for the use of this diagnostic tool among internists and specialists in pulmonary diseases.

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...
