Ultrasound I: Abdominal Ultrasonography01:20

Ultrasound I: Abdominal Ultrasonography

341
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 I: CT and MRI

417
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Ultrasonography01:17

Ultrasonography

5.1K
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...

Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Diagnostic Ultrasound

Background:

  • Traditional diagnostic methods for gastrointestinal (GI) diseases include endoscopy and barium enema.
  • Cross-sectional imaging like CT and MRI are increasingly used, but transabdominal ultrasonography (US) faces challenges due to bowel interference and image limitations.
  • Despite limitations, GIUS efficacy is recognized, with published guidelines from international federations.

Purpose of the Study:

  • To review current practices in gastrointestinal ultrasonography (GIUS).
  • To provide guidance on equipment, systematic scanning, and interpretation of GIUS findings.
  • To promote the effective use and global adoption of GIUS for diagnosing GI disorders.

Main Methods:

  • Systematic scanning based on sonoanatomy.
  • Precise estimation of layered wall structures using color Doppler.
  • Review of equipment perspectives, scanning procedures, normal GI tract findings, and 10 diagnostic items.

Main Results:

  • Optimal equipment settings and knowledge of sonoanatomy enable effective GIUS diagnosis.
  • Systematic scanning and color Doppler assessment allow for disease diagnosis and inflammation evaluation.
  • The review details normal findings and specific diagnostic criteria for various GI conditions.

Conclusions:

  • Gastrointestinal ultrasonography (GIUS) is an effective tool for diagnosing GI diseases.
  • Proper technique, including systematic scanning and color Doppler, is crucial for accurate diagnosis and inflammation assessment.
  • This review aims to enhance medical practitioners' ability to perform GIUS effectively.
