Ultrasonography01:17

Ultrasonography

8.3K
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...

Assessing Blood pressure using a doppler ultrasound01:19

Assessing Blood pressure using a doppler ultrasound

2.8K
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

422
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Imaging Studies VII: Vascular Imaging

448
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Area of Science:

  • Medical Imaging
  • Cardiovascular Technology
  • Biomedical Engineering

Background:

  • Vascular ultrasound has relied on B-mode, color flow, and spectral Doppler for 25 years.
  • Image quality improvements have been the primary change in vascular ultrasound technology.
  • Several advanced technologies have emerged with potential for clinical application.

Purpose of the Study:

  • To describe four key vascular ultrasound technologies and their research origins.
  • To assess the impact of these technologies on clinical practice.
  • To identify future trends in vascular ultrasound technology.

Main Methods:

  • Literature review tracing the research origins of four specific vascular ultrasound technologies.
  • Analysis of commercial availability and clinical impact of these technologies.
  • Discussion of emerging technologies and their potential future applications.

Main Results:

  • Four technologies discussed: 3D ultrasound (1994), color vector Doppler (1994), wall motion (1968), and shear wave elastography (2010).
  • Despite contributions to understanding vascular disease, these technologies have had minimal impact on clinical practice.
  • Improvements in image quality have been significant, while 2D array transducers and high frame rate imaging show future promise.

Conclusions:

  • Advanced vascular ultrasound technologies have largely failed to translate into widespread clinical practice.
  • Continued development in areas like 2D array transducers and high frame rate imaging may influence future clinical adoption.
  • Enhanced image quality remains a key driver of progress in vascular ultrasound.
