CT perfusion for stroke: Should you use it?

November 03, 2010

CT perfusion for stroke leaped from clinical discussion forums to the front pages in the last 13 months.

Contrast FLAIR tops FLAIR and contrast T1-weighted images

October 14, 2010

Contrast-enhanced FLAIR is more sensitive than other MRI techniques due to T2 prolongation and T1 shortening.

Contrast FLAIR tops FLAIR and contrast T1-weighted images

When considering which is the most sensitive MRI technique for detecting disease in the brain, the choice is usually between contrast-enhanced T1-weighted imaging and T2-weighted fluid-attenuated inversion recovery (FLAIR) imaging.

As era of 3T MR takes hold, new opportunities emerge

December 01, 2006

Like an expanding bubble, the number of MR applications continues to rise exponentially. Looking back over the last 27 years, I see several major MRI epochs: low- to midfield systems (late 1970s to mid-1980s), 1.5T with 10 mT/m gradients (mid-1980s to mid-1990s), and 1.5T with echo-planar gradients (mid-1990s to early 2000s). We entered a new epoch a few years ago: 3T with echo-planar gradients. Examining changes currently occurring, and understanding why they occur, can help us predict further changes to come over the next decade.
