The Episurf MRI Protocol Knee for Siemens MRI machines consists of six (or seven) MRI sequences. These include one 3D sequence and five (or six) 2D sequences: The settings for all these sequences are described in detail in the following text. 2. Protocol installation 2.1 Settings, 3D-sequenc Magnetic resonance imaging (MRI) offers considerable promise in this regard. Not only can MRI quantify articular cartilage volume and morphology with high precision and accuracy, but it can also examine several other important articular components, and thus offer a unique opportunity to evaluate the knee and other joints as whole organs

This physical therapy protocol applies to primary total knee arthroplasty. In a revision total knee arthroplasty, or in cases where there is more connective tissue involvement, Phase I and II should be progressed with more caution to ensure adequate healing. Progression to the next phase is based on Clinical Criteria and/or Time Frames a The MRI scanning protocol consists of 4 consecutive imaging sequences (excluding localizers). The first imaging sequence is a high‐resolution knee scan done with a knee coil. The last 3 scans are low‐resolution, done with the body coil, in succession, without moving the patient

In the United States, the number of joint replacements has increased; 332,000 total hip replacements and 719,000 total knee replacements were performed in 2010 . Simultaneously, there is a trend toward joint replacement occurring in younger, more active patients Purpose: Measurement protocols which have been optimized for MRI at field strengths of 1.5 T or 3 T cannot be directly transferred to 7 T. Specific absorption rate limitations, different tissue relaxation times, as well as new image artifacts require adjustments of the sequence parameters. The goal of our study was to investigate and optimize various sequences for 7 T imaging of the knee

A 5-minute knee magnetic resonance imaging protocol with parallel imaging is comparable to a standard knee MRI protocol, according to a study comparing the two that was conducted at New York University. Study results showed that the imaging results were diagnostically interchangeable and that the 5-minute knee MR images produced similar. Therefore, MRI, along with conventional tools like CT or X-rays, can help diagnose and evaluate conditions of the knee. Possible conditions include knee pain and swelling, bleeding in the tissues around the joint, fractures, tumors, both primary and metastatic, pain or trauma and complications of the knee.2 Magnetic resonance imaging (MRI) is a technology often used to investigate the sources of knee problems. 1  It works by creating a magnetic field that causes the water molecules in tissue, bones, and organs to orient themselves in different ways.
