Can MRI Replace CT in Evaluating Semicircular Canal Dehiscence?
WebMRI machines work by exploiting the interaction of the magnetic field, hydrogen ions, and radiofrequency (RF) pulse. When you put a patient in a strong magnetic field, their hydrogen ions align in the direction of the magnetic field. Applying an RF pulse will change the direction of alignment of these hydrogen ions. WebThe FIESTA MRI might be considered as an additional method to evaluate the movement of the articular disk and the mandibular condyle. Most TMJs images with a slow free open-close movement (cycles≦3) could be successfully obtained by the dynamic FIESTA MRI. its dark and hell is hot release date
