|July 25, 2012
Summary
Imaging research in osteoarthritis (OA) saw a decline in publications, with magnetic resonance imaging (MRI) and radiography studies decreasing significantly. Most OA imaging research focuses on the knee, but hand imaging is gaining traction.
Area of Science:
- Orthopedics and Musculoskeletal Disorders
- Radiology and Medical Imaging
- Biomedical Research
Background:
- Osteoarthritis (OA) is a degenerative joint disease impacting millions worldwide.
- Accurate and advanced imaging techniques are crucial for understanding OA progression and developing effective treatments.
- The landscape of OA imaging research is dynamic, necessitating regular reviews of current trends and methodologies.
Purpose of the Study:
- To conduct a comprehensive review of original English-language publications on osteoarthritis imaging.
- To analyze trends in imaging modalities, including MRI, radiography, and ultrasound, from September 2011 to March 2012.
- To provide an overview of imaging research impact within the OA community, excluding in vitro and animal studies.
Main Methods:
- An extensive PubMed search was performed using keywords: "osteoarthritis" combined with specific imaging modalities (MRI, radiography, ultrasound, CT, nuclear medicine).
- Publications were selected based on relevance and potential impact, focusing on high-impact journals.
- Literature was categorized by imaging type (radiography, various MRI techniques, ultrasound) and joint site, excluding OARSI 2012 presentations.
Main Results:
- A notable decrease in publications was observed for "MRI and osteoarthritis" (-38.1%) and "radiography and osteoarthritis" (-56.9%) during the review period.
- Magnetic resonance imaging (MRI) studies predominantly focused on epidemiologic and methodologic aspects of OA.
- Radiography and ultrasound received significantly less research attention compared to MRI.
Conclusions:
- The period reviewed showed a decline in OA imaging research output, particularly in radiography.
- While knee imaging remains dominant, there is a growing research interest in imaging other joints, notably the hand.
- MRI continues to be a primary focus for OA imaging research, with an emphasis on epidemiological and methodological advancements.

01:17Ultrasonography
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.

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...
01:19Imaging Studies VII: Vascular Imaging
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...
