Increased reproducibility in RV mass measurement at end-systole
Background Cardiovascular magnetic resonance (CMR) has been shown to be accurate and reproducible for right ventricular (RV) function evaluation. RV mass, assessed in enddiastolic (ED) phase, is one of the least reproducible CMR derived variables. The end-systolic (ES) phase could offer an alternative way to improve reproducibility, since the selection of basal slice and visualization of the us...
متن کاملUmbilical venous blood flow measurement: accuracy and reproducibility.
Umbilical venous blood flow could be considered a direct and physiological measurement of vascular placental function, representing the quantity of oxygen and nutrients reaching the fetus. The advent of high-technology ultrasound and pulsed Doppler has overcome some of the limitations of early studies. Indeed, Doppler measurement of umbilical venous blood flow has been found to be accurate when...
متن کاملDiffusion MRI tractography of the human heart In Vivo at end-diastole and end-systole
Diffusion Tensor MRI (DTI) of the human heart in vivo has to date been performed in 2D and at a single phase of the cardiac cycle. Here we perform 3D tractography of the human heart in vivo at both end diastole and end systole. We show that fiber orientation in the subepicardium becomes more oblique during systole, and that scalar indices of diffusion (mean diffusivity and fractional anisotropy...
متن کاملRight ventricular mass has better reproducibility in systole than diastole in patients with suspected pulmonary hypertension
Background Accurate estimation of right ventricular (RV) measurements is important in the clinical assessment of patients with pulmonary hypertension and has a potential role as an end-point in clinical trials. However, there is no clear agreement as to how RV mass measurements should be performed. RV mass is traditionally measured in diastole even though RV musculature is known to be thicker i...
متن کاملAnatomy-aware measurement of segmentation accuracy
Quantifying the accuracy of segmentation and manual delineation of organs, tissue types and tumors in medical images is a necessary measurement that suffers from multiple problems. One major shortcoming of all accuracy measures is that they neglect the anatomical significance or relevance of different zones within a given segment. Hence, existing accuracy metrics measure the overlap of a given ...
