Risonanza Magnetica Whole Body con Diffusione

🗞️ Subscribe to our newsletter: https://www.usi.it/newsletter-usi 🔎 Book your exam: https://www.usi.it/ Whole-body diffusion imaging is an MRI technique that allows us to examine the entire body without ionizing radiation (i.e., potentially dangerous radiation) and without the use of contrast agents, which in some cases can cause serious allergic reactions. For the first time, a complete, reliable, and simple examination of the human body is available, without any risks whatsoever. The name of this technique (diffusion) refers to an application of MRI that is sensitive to the diffusion of water molecules. In tumors, the diffusion of water molecules is lower because the density of tumor cells is higher. Whole-body diffusion detects the movement of water molecules, which glow when they are concentrated in tumor tissue. Malignant tumors are significantly brighter than healthy tissue. The full-body scan lasts about 20 minutes, during which the patient must remain still. The images obtained are very similar to those of a CT scan. PET is an invasive test that involves the use of radioactive nuclear medicine. It is widely used in oncology but cannot be used in normal subjects. The non-invasive nature of the technique allows it to be used extremely safely for whole-body cancer screening. It should be noted that this type of scan can only be performed with high-field MRI machines ranging from 1.2 (or 1.5?) to 3 Tesla, such as those available at USI.
