Inversion recovery and saturation recovery pulmonary vein MR angiography using an image based navigator fluoro trigger and variable-density 3D cartesian sampling with spiral-like order.

Contrast enhanced pulmonary vein magnetic resonance angiography (PV CE-MRA) has value in atrial ablation pre-procedural planning. We aimed to provide high fidelity, ECG gated PV CE-MRA accelerated by variable density Cartesian sampling (VD-CASPR) with image navigator (iNAV) respiratory motion correction acquired in under 4 min. We describe its use in part during the global iodinated contrast shortage.

Comparative Evaluation of Creatinine and Cystatin C Derived Glomerular Filtration Rate Methods in Hiv Patients on Therapy and Healthy Controls.

Background: Antiretroviral drugs are associated with adverse effects including chronic kidney disease. The onset of chronic kidney disease manifests with mild reduction in GFR. Early detection of chronic kidney disease is integral component of clinical medicine with major effect on disease labeling, intervention and drug dosing.

Arterial stiffness and left ventricular structure assessed by cardiac computed tomography in a multiethnic population.

Background: Arterial stiffness expressed by cardio-ankle vascular index (CAVI) is a marker of arteriosclerosis. It can increase vascular load, which in turn may affect the viscoelastic myocardial properties and the left ventricular compliance. In the present study, we sought to investigate the association between CAVI and left ventricular structure assessed by cardiac computed tomography (CT) in a multiethnic adult cohort.

Harmonizing multimodality imaging results using Bayesian analysis: the case of CT coronary angiography and CT-derived fractional flow reserve.

Coronary computed tomographic angiography (CCTA) may provide both anatomic and CT fractional flow reserve data (CTFFR). The objective is to use Bayesian analysis to develop a model wherein the probability of significant coronary artery disease (CAD) by CTFFR can be determined given the prior probability (P) of the combined clinical and CCTA result. 172 patients referred for CCTA and subsequently underwent coronary angiography were automatically referred to CTFFR analysis.
