Ultrasound II: Endoscopic Ultrasound and FibroScan

Ultrasound II: Endoscopic Ultrasound and FibroScan

Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.
Endoscopic Ultrasound (EUS):

Ultrasonography

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...

Hearing

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

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...

Ultrasound I: Abdominal Ultrasonography

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...

Summary

Pacific herring cannot detect ultrasound, unlike some related fish. Their hearing is limited to lower frequencies, which may explain their responses to certain sounds.

Area of Science:

Marine Biology
Bioacoustics
Fisheries Science

Background:

Some clupeid fishes, like shad and menhaden, detect and avoid ultrasound (>20 kHz).
Other clupeids, such as sardines and anchovies, do not detect ultrasound.
Pacific herring (Clupea pallasii) are commercially important, and acoustic monitoring is vital for population assessment.

Purpose of the Study:

To determine the hearing sensitivity of Pacific herring to ultrasonic frequencies.
To understand if herring possess ultrasound detection capabilities.
To compare herring hearing abilities with other clupeid species.

Main Methods:

Auditory brainstem response (ABR) was used to measure hearing sensitivity.
Testing focused on the ability to detect ultrasonic signals.

Hearing thresholds were assessed across a range of frequencies.

Main Results:

Pacific herring were unable to detect ultrasonic signals up to 185 dB re 1 microPa.
Herring exhibited typical non-ultrasound-detecting clupeid hearing thresholds at lower frequencies (100-5000 Hz).

Conclusions:

Pacific herring lack the ability to detect ultrasound.
Their lower-frequency hearing sensitivity may explain observed behavioral responses to broadband sounds.
Findings contribute to understanding fish bioacoustics and acoustic impacts on marine populations.
