Summary
Computed tomography (CT) and magnetic resonance (MR) arthrography are safe and effective for diagnosing cartilage injuries. These techniques help assess joint stability and guide treatment decisions for osteochondral lesions.
Area of Science:
- Radiology
- Orthopedics
- Medical Imaging
Background:
- Articular cartilage imaging is crucial for diagnosing joint diseases.
- Conventional MRI, CT, and MR arthrography are established methods for cartilage evaluation.
- Radiologists require expertise in indications and safe injection techniques for arthrography.
Purpose of the Study:
- To detail cross-sectional arthrography techniques for various joints.
- To provide general and joint-specific considerations for practical arthrography application.
- To outline common indications for cartilage imaging using arthrography.
Main Methods:
- A literature search was conducted on PubMed using keywords related to arthrography and cartilage imaging.
- The search included terms like 'CT arthrography', 'MR arthrography', 'cartilage lesion', and specific joint arthrography.
Main Results:
- CT and MR arthrography are valuable and safe for cartilage imaging.
- These methods verify and specify chondral pathologies, aiding therapeutic decisions for osteochondral lesions.
- CT arthrography offers higher resolution in small joints (wrist, elbow, ankle) compared to MR arthrography.
Conclusions:
- CT and MR arthrography are essential tools for evaluating chondral and osteochondral lesions.
- CT arthrography can be advantageous in small joints due to superior resolution.
- Ultrasound guidance is increasingly used for joint puncture, and joint traction shows promise for MR arthrography.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

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...

Implementation is the execution of the nursing care plan developed during the planning phase.
The five steps to implementing effective nursing care include reassessing the patient, reviewing and revising the existing nursing care plan, organizing the resources and care delivery, anticipating and preventing complications, and implementing nursing interventions.

2.7K
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...
