Summary
This summary is machine-generated.Ultrasound (US) is a reliable and valid tool for screening dysphagia, or swallowing impairment. This systematic review and meta-analysis confirms its effectiveness in clinical practice.
Area Of Science
- Diagnostic imaging
- Swallowing disorders
- Ultrasound applications
Background
- Dysphagia, or swallowing impairment, can be conveniently identified using ultrasound (US).
- Evaluating the validity and reliability of US measurements for assessing swallowing function is crucial.
Purpose Of The Study
- To conduct a systematic review and meta-analysis.
- To evaluate the validity and reliability of US measurements for assessing dysphagia and swallowing impairment in adults.
Main Methods
- Systematic search of Embase, Medline, Cochrane Library, Web of Science, CINAHL, and Scopus databases.
- Inclusion of 38 studies assessing US measurements like hyoid bone displacement, thyrohyoid approximation, and muscle thickness.
- Data synthesis using random-effects meta-analysis following PRISMA guidelines.
Main Results
- Pooled sensitivities and specificities for US measurements in identifying dysphagia were reported.
- Correlation coefficients for displacement and cross-sectional area (CSA) with swallowing function were calculated.
- High intrarater and interrater reliability values were observed for various US parameters, including displacement, CSA, and muscle thickness.
Conclusions
- Ultrasound (US) demonstrates reliability and validity as a screening tool for dysphagia and swallowing impairment.
- Standardized and universal US protocols are recommended to enhance comparability and reliability in clinical settings.

Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.
Endoscopic Ultrasound (EUS):
Technological Integration: EUS is a sophisticated integration of optical endoscopy and ultrasonography. The endoscope visualizes the mucosal surface directly, while the ultrasound component penetrates deeper to visualize organs and structures beyond the gastrointestinal wall.

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...
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...
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection....
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
