High-resolution pulmonary arterio- and venography using multiple-bolus multiphase 3D-Gd-mRA.
The purpose of this study was to demonstrate selective visualization of pulmonary arteries and veins with high spatial resolution for improved detection of vascular pathologies. Time-resolved pulmonary three-dimensional gadolinium-enhanced magnetic resonance angiograms (3D-Gd-MRA) were acquired with an ultrashort 3D fast low-angle shot (FLASH) sequence (TR/TE 2.3/0.9 msec) using asymmetric k-sp...
متن کاملFlexible phase-encoding in 3D coronary MRA with balanced SSFP
Fig. 3. Comparison of PE schemes in bSSFP CMRA of the right coronary artery. Conspicuity of the distal RCA was good in all three schemes. Fig. 2. Flexible PE schemes with partial Fourier acquisition in the PE (kY) dimension and k-space corners removed from sampling, colorized from red to blue to reflect the sequence of acquisition. Plots of the first and last acquisition trains are shown, refle...
متن کاملtreating refractory hypertension: renal denervation with high-resolution 3d-angiography
a 53-year-old male was referred to our department for refractory primary hypertension. despite high doses of 6 anti-hypertensive drugs, ambulatory monitoring of blood pressure (bp) revealed a mean bp of 160/90 mmhg. under local anaesthesia, renal denervation with radiofrequency was performed supported by high-resolution 3d angiography, which helped confirm the position of the applications in a ...
متن کاملVRI: 3D QSAR at variable resolution
Ž . ABSTRACT: VRI Variable Resolution Invariants is a new approach to quantitative structure]activity relations that makes use of three-dimensional features of molecules at different levels of spatial resolution as well as levels of resolution in atomic properties. These descriptors are independent of any numbering of the atoms of a molecule. They are also independent of rigid translation and r...
متن کاملWhole-Heart Coronary MRA
Background MRI was first reported to visualize the ostia of the coronary arteries in the late 1980’s (1, 2). Tremendous progress has been made in coronary MRA ever since. One of the milestones was the acquisition of k-space data in a segmented mode (3, 4), allowing collection of an entire data set within multiple heartbeats. Early coronary MRA studies used two-dimensional (2D) technique to acqu...
