Summary
Estimating left ventricular volume (LVV) and ejection fraction (LVEF) has significant errors. A 3D surface model using multiple views dramatically improves accuracy for better cardiac disease detection.
Area of Science:
- Cardiovascular Imaging
- Medical Physics
- Biomedical Engineering
Background:
- Left ventricular cavity volume (LVV) and ejection fraction (LVEF) are critical for clinical decisions.
- Current estimation methods have underappreciated and unquantified clinical errors.
Purpose of the Study:
- To rigorously quantify the accuracy and precision of common geometric-model-based LVV and LVEF estimation methods.
- To evaluate the impact of slice number and orientation on LVV and LVEF accuracy.
Main Methods:
- Utilized a high-resolution magnetic resonance imaging dataset with an independent ground truth.
- Assessed various geometric modeling techniques, including short-axis, long-axis, and combined 3D surface models.
- Investigated the influence of slice count and orientation on measurement uncertainty.
Main Results:
- Standard methods with limited views can yield LVEF uncertainty up to 49%.
- A 3D surface model incorporating multi-view anatomical data achieved superior accuracy: LVEF error <4% and LVV error <2.5% with 6 slices per view.
- Combined 3D models significantly outperformed methods relying solely on short-axis images.
Conclusions:
- Integrating multi-view anatomical data into conformal 3D surface models substantially reduces LVV and LVEF estimation errors.
- This improved accuracy holds significant potential for earlier and more reliable cardiac disease detection in clinical practice.

A line integral for a vector field is defined as the integral of the dot product of a vector function with an infinitesimal displacement vector along a prescribed path. If the prescribed path is closed, the integrals reduce to a closed-line integral. The closed-contour integral of the vector field is referred to in terms of the circulation of the vector field around the closed path. A vector with zero circulation around every closed path is called a conservative field, while one with non-zero...

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being consumed or permanently changed. They reduce the activation energy needed to convert the reactants into products. Enzymes are proteins, that usually work by binding to a substrate—a reactant molecule that they act upon.
Enzymes exhibit substrate specificity, meaning that they can only bind to certain substrates. This is mainly determined by the shape and chemical...

03:37Uncertainty in Measurement: Accuracy and Precision
100.8K
Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value.

Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

The goodness-of-fit test is a type of hypothesis test which determines whether the data "fits" a particular distribution. For example, one may suspect that some anonymous data may fit a binomial distribution. A chi-square test (meaning the distribution for the hypothesis test is chi-square) can be used to determine if there is a fit. The null and alternative hypotheses may be written in sentences or stated as equations or inequalities. The test statistic for a goodness-of-fit test is given as...
