Abstract:
Fine needle aspiration biopsy (FNA) is the key step in selecting most patients with thyroid nodules for or against surgery. Accurate acquisition of cytologic samples from suspicious lesions is achieved by adding ultrasound guidance to optimize targeting as well as to enable sampling from nonpalpable lesions. This article discusses the indications, variations, and technical details of ultrasound-guided FNA.

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...
