Marro K, Lee D, Shankland E, Mathis C, Hayes C
J Magn Reson Imaging . 2011 Nov; 34(6):1414-21. PMID: 22113992
Purpose: To demonstrate that, when injecting an artificial reference signal for quantitation purposes, the real and artificial signals can be acquired separately, using a single radiofrequency (RF) channel, with no...

Marro K, Lee D, Shankland E, Mathis C, Hayes C, Friedman S, et al.
PLoS One . 2011 Jan; 5(12):e15166. PMID: 21203385
Accurate conversion of magnetic resonance spectra to quantitative units of concentration generally requires compensation for differences in coil loading conditions, the gains of the various receiver amplifiers, and rescaling that...

Khokhlova T, Canney M, Lee D, Marro K, Crum L, Khokhlova V, et al.
J Acoust Soc Am . 2009 Apr; 125(4):2420-31. PMID: 19354416
Both mechanically induced acoustic cavitation and thermally induced boiling can occur during high intensity focused ultrasound (HIFU) medical therapy. The goal was to monitor the temperature as boiling was approached...

Marro K, Hyyti O, Kushmerick M
NMR Biomed . 2005 May; 18(5):322-30. PMID: 15884098
Arterial spin labeling (ASL) techniques are now recognized as valid tools for providing accurate measurements of cerebral and cardiac perfusion. The labeling process used with most ASL techniques creates two...
