To evaluate the magnetic susceptibility properties of different anatomical structures within the knee joint using quantitative susceptibility mapping (QSM).


The arrangement of the collagen fibrils is significant, and likely the most dominant source of magnetic susceptibility anisotropy. Quantitative susceptibility mapping offers a means to characterize magnetic susceptibility properties of tissues in the knee joint. It is sensitive to collagen damage or degeneration and may be useful for evaluating the status of knee diseases, such as meniscal tears and cartilage disease.

Evaluar las propiedades de susceptibilidad magnética de diferentes estructuras anatómicas dentro de la articulación de la rodilla utilizando la cartografía cuantitativa de susceptibilidad (QSM).

La disposición de las fibrillas de colágeno es significativa y, probablemente, la fuente más dominante de susceptibilidad magnética anisotropía. La cartografía cuantitativa de susceptibilidad ofrece un medio para caracterizar las propiedades de susceptibilidad magnética de los tejidos en la articulación de la rodilla. Es sensible al daño o degeneración del colágeno y puede ser útil para evaluar el estado de las enfermedades de la rodilla, como los desgarres meniscales y la enfermedad del cartílago.

    Good blog! I really love how it is simple on my eyes and the data are well written. I am wondering how I could be notified when a new post has been made. I’ve subscribed to your RSS feed which must do the trick! Have a nice day!

  1. There are amazing modifications on the design of your webpage, I honestly like that! My site is about ticket dispute and presently there are a lot of stuff to do, I am yet still a starter in webpage design. Take good care!

  2. I’m curious to understand which site system you have been working with? I’m experiencing some small protection issues with my most recent website on free credit card numbers and I’d like to find one thing much more secure. Do you have any strategies?
