Ultrasound I: Abdominal Ultrasonography01:20

Ultrasound I: Abdominal Ultrasonography

Introduction:
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...

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Area of Science:

  • Radiology
  • Oncology
  • Pathology

Background:

  • Ultrasound-guided fine needle aspiration biopsy (FNAB) is a valuable tool for lesion evaluation.
  • It serves as an effective alternative to surgical procedures for malignancy assessment.
  • Minimizing unnecessary operations is crucial in diagnostic pathways.

Purpose of the Study:

  • To present an effective and accessible protocol for ultrasound-guided FNAB.
  • To guide residents and physicians with limited interventional experience.
  • To standardize the FNAB procedure for improved diagnostic accuracy.

Main Methods:

  • The study is based on over 350 FNAB procedures performed over two years.
  • The protocol includes detailed patient preparation, needle selection, and aspiration techniques.
  • Visual aids such as images and graphics are incorporated for clarity.

Main Results:

  • The protocol facilitates accurate detection and evaluation of both solid and cystic lesions.
  • On-site cytologic preparation is described for rapid preliminary diagnosis.
  • The procedure is demonstrated to be easily performed with high effectiveness.

Conclusions:

  • This tutorial provides a practical, easy-to-follow protocol for ultrasound-guided FNAB.
  • It aims to enhance the skills of physicians performing interventional procedures.
  • The described method aids in reducing unnecessary surgical interventions for lesion evaluation.
