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...

Area of Science:

Orthopedics
Radiology
Medical Imaging

Background:

Radiography is the standard for osteoarthritis (OA) diagnosis but struggles with early-stage detection and progression monitoring.
Early recognition of OA remains a significant clinical challenge despite treatment advancements.

Purpose of the Study:

To review current advanced imaging modalities for osteoarthritis (OA) diagnosis and monitoring.
To evaluate the effectiveness of various imaging techniques beyond conventional radiography for OA assessment.

Main Methods:

A clinical review of literature published between 2006 and 2016.
Searches were conducted on MEDLINE, PubMed, and professional orthopaedic and imaging websites.
Study design was a Level 4 clinical review.

Main Results:

Magnetic resonance imaging (MRI) offers comprehensive, noninvasive assessment of joint injury and OA with superior soft tissue detail.
Computed tomography (CT) and CT arthrography (CTA) can evaluate OA but involve radiation and are invasive.
Ultrasound is effective for synovitis but not for tracking OA progression.

Conclusions:

MRI, CT, and CTA are viable options for diagnosing and monitoring osteoarthritis (OA).
Technological improvements and cost reductions may enhance the utility of these advanced modalities for early OA detection.
