T1 maps by K-space reduced snapshot-FLASH MRI.

Journal of computer assisted tomography

Nekolla S, Gneiting T, Syha J, Deichmann R, Haase A.
PMID: 1545039
J Comput Assist Tomogr. 1992 Mar-Apr;16(2):327-32. doi: 10.1097/00004728-199203000-00031.

The T1 maps evaluated from k-space reduced Snapshot fast low angle shot (FLASH) images provide high contrast parameter images for tissue characterization in vivo of any body region. An algorithm for computing T1 values that allows a fast and...

Snapshot FLASH MRI. Applications to T1, T2, and chemical-shift imaging.

Magnetic resonance in medicine

Haase A.
PMID: 2319937
Magn Reson Med. 1990 Jan;13(1):77-89. doi: 10.1002/mrm.1910130109.

Snapshot FLASH magnetic resonance imaging techniques have been developed to enable real-time imaging of MR parameters. The first realization of the method is based on a 64 X 128 FLASH tomogram acquired within 200 ms, using improved MR system...

A study of optimization of the complex hyperbolic secant inversion pulses.

Magnetic resonance in medicine

Mao J, Virapongse C, Fitzsimmons JR.
PMID: 2314217
Magn Reson Med. 1990 Feb;13(2):293-8. doi: 10.1002/mrm.1910130211.

The conjugate gradient method is used to optimize the inversion slice profile produced by complex hyperbolic secant selective pulses. An improved quality is obtained for the inversion slice profile at a price, however, of a lower immunity to the...

Slice profile improvement for a clinical MRI system.

Magnetic resonance imaging

Mao JT, Yan H, Fitzsimmons JR.
PMID: 2266803
Magn Reson Imaging. 1990;8(6):767-70. doi: 10.1016/0730-725x(90)90012-q.

Optimal control methods have been recently introduced to improve the design of selective radio frequency pulses and several optimized selective pulses that can produce excellent slice profiles have been reported. These pulses usually require high peak rf amplitudes to...

Current opinion in radiology

Revel D, Finck B.
PMID: 2204397
Curr Opin Radiol. 1990 Aug;2(4):581-5.

Directions in magnetic resonance imaging technology.

Medical progress through technology

Ortendahl DA, Crooks LE.
PMID: 2533656
Med Prog Technol. 1989;15(3):171-84.

Over the past few years there have been substantial improvements in the performance of magnetic resonance (MR) imagers. As image quality improved it became possible to perform studies in less time, increasing the throughput and the availability of the...

Two-dimensional selective adiabatic pulses.

Magnetic resonance in medicine

Conolly S, Pauly J, Nishimura D, Macovski A.
PMID: 1569869
Magn Reson Med. 1992 Apr;24(2):302-13. doi: 10.1002/mrm.1910240211.

Using the technique of separable k-space excitation, we have designed a two-dimensional selective adiabatic pulse that inverts magnetization from a square region in the xy plane with insensitivity to RF variations. We also have designed a two-dimensional adiabatic pulse...

A new approach to split resonator design.

Magnetic resonance in medicine

Harpen MD.
PMID: 1569874
Magn Reson Med. 1992 Apr;24(2):364-9. doi: 10.1002/mrm.1910240217.

Using a novel application of the method of images we show how a plane array of resonant elements can be substituted for the conducting plane in a semicylindrical or split resonator. In an experimental low-pass split resonator-plane array system...
