  1. Qual è la differenza tra MRI e MRA? Un MRA, o angiografia a risonanza magnetica, è un tipo di risonanza magnetica che utilizza i campi magnetici e le onde radio della risonanza magnetica per produrre immagini di vasi sanguigni all'interno del corpo, consentendo ai medici di individuare i problemi che potrebbero causare una riduzione del flusso sanguigno
  2. Riassunto; L'imaging del tenso re di diffusione (DT I) è una tecnica RM che permette l'analisi delle proprietà diffusive e della direzionalità del flusso delle molecole d'acqua all'interno dei tessuti in vivo.

Hyperpolarized (HP) carbon 13 (13 C) MRI is an emerging molecular imaging method that allows rapid, noninvasive, and pathway-specific investigation of dynamic metabolic and physiologic processes that were previously inaccessible to imaging.This technique has enabled real-time in vivo investigations of metabolism that are central to a variety of diseases, including cancer, cardiovascular. An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body. MRIs are more detailed in their images. Choosing between an MRI and CT scan Magnetic resonance imaging or MRI is a non-invasive radiology scan used to diagnose diseases, diagnosis, and to monitor treatment. MRIs are painless, and it avoids X-ray radiation exposure. Side effects of an MRI are claustrophobia and anxiety An MRI machine creates the images using a magnetic field and radio waves. This test is also known as a brain MRI or a cranial MRI. You will go to a hospital or radiology center to take a head MRI
