Measurement of pulmonary arterial pulse wave reflection from single-slice phase-contrast and steady-state free precession MRI
نویسندگان
چکیده
Pulmonary arterial hypertension (PAH) is associated with elevated pulmonary vascular resistance, resulting in increased reflection of pressure and flow waves from distal vessels. The gold standard for assessing PAH is right heart catheterization, an invasive procedure that carries a 5% risk of major complications. We validate a noninvasive method for quantifying pulmonary arterial reflection using phase-contrast (PC) and steady-state free precession (SSFP) sequences acquired in a single slice.

Balanced Phase Contrast Steady State Free Precession (PC-SSFP): Velocity Encoding by Gradient Inversion
chnique for velocity measurements (PC-SSFP) is presented that combines CINE Phase Contrast (PC) MRI and balanced Steady State Free Precession. Sensitivity to through plane velocities was established by inverting (i.e. negating) the slice select gradient for consecutively executed balanced SSFP pulse sequences. Velocity sensitivity (venc) could be adjusted by increasing the first moments of the ...

INTRODUCTION: Balanced steady-state free precession (b-SSFP) techniques yielding high SNR images in short scan times with T2-like image contrast have several appealing attributes for clinical breast MRI [1]. Clinical T2 imaging in the breast is routinely performed using a fat suppressed 2D Fast Spin Echo (FSE) pulse sequence with high in-plane spatial resolution. The 3-5 mm slice thickness obsc...
متن کاملSSFP and GRE phase contrast imaging using a three-echo readout.
A technique for rapid in-plane phase-contrast imaging with high signal-to-noise ratio (SNR) is described. Velocity-encoding is achieved by oscillating the readout gradient, such that each 2DFT phase-encode is acquired three times following a single RF slice-selective excitation. Three images are reconstructed, from which both flow velocity and local resonance offset are calculated. This techniq...
