Osteoarthritis and Cartilage
|November 3, 2024
Summary
Recent literature shows magnetic resonance imaging (MRI) remains crucial for osteoarthritis (OA) research. Artificial intelligence (AI) is increasingly used alongside human assessment in OA imaging studies.
Area of Science:
- Orthopedics
- Radiology
- Medical Imaging
Background:
- Osteoarthritis (OA) is a prevalent degenerative joint disease.
- Accurate imaging is essential for OA diagnosis, staging, and research.
- Current research trends in OA imaging require regular review.
Purpose of the Study:
- To review recent literature on osteoarthritis (OA) imaging.
- To identify emerging trends in OA imaging research.
Main Methods:
- Narrative review of English publications from April 2023 to March 2024.
- PubMed search using terms: osteoarthritis, radiography, ultrasound, CT, MRI, DXA, AI.
- Focused on knee and hip OA imaging, including AI applications.
Main Results:
- No significant change in CT, MRI, and AI publications compared to the previous year.
- Reduction in radiography and ultrasound OA research papers.
- Observational studies on knee and hip OA were prominent; AI applications in OA imaging were also covered.
Conclusions:
- Magnetic resonance imaging (MRI) continues to be a dominant modality in OA imaging research.
- Artificial intelligence (AI) tools are increasingly integrated as adjuncts in OA imaging research.

01:23Knee Joint
1.5K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

01:20Imaging Studies for Cardiovascular System III: X-Ray
147
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

4.3K
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.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

01:31Osteoclasts in Bone Remodeling
2.8K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...
