MR Finger Printing-will it change MRI as we know?
An article in Nature reports a new technique called MR finger printing.   Authors introduce novel approach to data acquisition, post-processing and visualization—which is termed ‘magnetic resonance fingerprinting’ (MRF)—that permits the simultaneous non-invasive quantification of multiple important properties of a material or tissue. MRF thus provides an alternative way to quantitatively detect and analyse complex changes that can represent physical alterations of a substance or early indicators of disease. When paired with an appropriate pattern-recognition algorithm, MRF inherently suppr...

Multisystem Atrophy versus Parkinsonism-MRI- Teaching Points
What your Neurologist wants to know?  Brain MRI in patients with MSA-P and MSA-C may reveal atrophy of the putamen, pons, and middle cerebellar peduncles. On T2 MRI sequences, signal changes include hypointensity of the posterior putamen (also described as a slit-like void), a hyperintense lateral putaminal rim, and hyperintensities of the middle cerebellar peduncles. These changes are supportive of the diagnosis of MSA rather than idiopathic Parkinson disease.  The "hot cross bun sign" refers to hyperintense T2 signal in the shape of a cross within the pons that arises from degeneration of transvers...

Most MR systems in use today operate at fields ranging from 0.2- to 3-Tesla. According to the latest guidelines from the U.S. Food and Drug Administration, clinical MR systems using static magnetic fields up to 8.0-Tesla are considered a “non-significant risk” for adult patients. The exposure of research subjects to fields above this level requires approval of the research protocol by an Institutional Review Board and the informed consent of the subjects.  Currently, the most powerful MR system used for human subjects operates at 9.4-Tesla, but there are plans to develop even higher field strength scanners...
