Field mapping without reference scan using asymmetric echo-planar techniques.
Improvements in Bo mapping and shimming were achieved by measuring the static field information in multiple subsequent echoes generated by an asymmetric echo-planar readout gradient train. With careful compensation, eddy current effects were shown to affect the adjustment of the shim coils minimally. In addition to reducing the time required for field mapping by two-fold, the sensitivity was si...
متن کاملEcho-Planar Susceptibility Mapping
Purpose: Quantitative susceptibility mapping (QSM) is a valuable new approach for subcortical brain iron mapping [1,2]. However, acquisition times are typically on the order of 5-10 minutes, which is acceptable in dedicated studies but limits wider use in the clinic for standard brain exams due to the considerable time penalty. The aim is to develop and test an extremely rapid means (under 10 s...

متن کاملA novel object-independent "balanced" reference scan for echo-planar imaging.
Interleaved echo-planar imaging (EPI) is susceptible to significant ghosting artifacts, resulting primarily from system time delays that cause data matrix misregistration. Most EPI applications rely on "reference scans" to measure delays, and post-processing algorithms are used to correct these errors. Unfortunately, delay estimates made with most reference scan techniques are object dependent,...
متن کاملRapid T2* mapping using interleaved echo planar imaging.
Magnetic resonance imaging methods that are sensitive to T2* are widely used in the study of blood oxygenation changes, most notably in functional studies of the brain. In these studies the signal intensity change in T2*-weighted imaging is related to the coupling of cerebral blood flow and metabolism. Rapid measurement of T2* itself would offer a valuable method to quantify blood oxygenation c...
