One of the great advantages of MRI is its ability to image physiological flow of fluids (e.g. blood flow) often without the need for intravenous contrast. This allows for the imaging of arteries, veins and CSF flow. Read more about MR angiography. Read more about MR venography. Read more about CSF flow studies. See more The simplest way to think about the multitude of sequences available on modern scanners is to divide them according to the dominant influence on the appearance of … See more When describing most MRI sequences we refer to the shade of grey of tissues or fluid with the word intensity, leading to the following absolute terms: 1. high signal intensity = white 2. intermediate signal intensity = grey 3. low … See more T2 weighted (T2W) sequences are part of almost all MRI protocols. Without modification the dominant signal intensities of different … See more T1 weighted (T1W) sequences are part of almost all MRI protocols and are best thought of as the most 'anatomical' of images (historically the T1W sequence was known as the … See more WebThe history of NMR (known as MRI) begins with a french mathematician Jean Baptiste Joseph Fourier (1768–1830) who developed a mathematical method to analyze the heat transfer between solid bodies. Later this discovery made rapid processing of phase and frequency signals possible in NMR. The unit strength of a magnetic field is the Tesla (1 ...
