Ultrasonography01:17

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...
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...

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...
Imaging Studies for Cardiovascular System I:Echocardiography01:17

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...
Thoracic Aorta01:15

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

Area of Science:

  • Emergency Medicine
  • Radiology
  • Critical Care Medicine

Background:

  • Dyspnea and hypotension pose diagnostic challenges in emergency settings.
  • Traditional evaluation methods have limitations.
  • Lung ultrasound (LUS) is increasingly essential for thoracic emergencies.

Purpose of the Study:

  • To review the principles of thoracic ultrasound.
  • To describe sonographic features of key thoracic emergencies.
  • To provide a framework for using LUS in severe dyspnea assessment.

Main Methods:

  • Review of evidence-based sonographic features.
  • Focus on pneumothorax, pleural effusion, pneumonia, and pulmonary edema.
  • Framework development for clinical application.

Main Results:

  • Lung ultrasound demonstrates high sensitivity, comparable to CT scans for many indications.
  • Key sonographic findings for specific conditions are outlined.
  • A structured approach to LUS in dyspnea is presented.

Conclusions:

  • Thoracic ultrasound is a fundamental technique for assessing patients with severe dyspnea.
  • LUS aids emergency physicians in diagnosing critical thoracic conditions efficiently.
  • The review provides practical guidance for integrating LUS into clinical practice.
