Abstract:
Linear array endosonography, with its capacity to perform EUS-guided FNA and EUS-guided injections, as well as color mapping and Doppler ultrasonography, is becoming an important instrument for the endosonographer. Familiarity with linear array anatomy, as introduced here, is the critical foundation on which these diagnostic and therapeutic procedures can be performed safely and effectively.

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...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
