Decreasing Function01:27

Decreasing Function

267
A decreasing function describes a relationship where the output consistently declines as the input increases. This means that for any two input values, if one is greater than the other, the corresponding output is smaller. Mathematically, a function f is decreasing on an interval I if for every x1 < x2​ in I, f (x1) > f (x2). This type of behavior is visually identified on a graph that slopes downward from left to right.The nature of a function can be analyzed by calculating...

Decreased Body Temperature01:29

Decreased Body Temperature

1.0K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Decreased pulse rate01:14

Decreased pulse rate

894
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Partial Fractions01:28

Partial Fractions

215
A partial fraction is a component of a rational expression represented as the sum of simpler fractions. When a rational function is expressed as a ratio of two polynomials, it can often be decomposed into a sum of fractions whose denominators are simpler polynomials, typically linear or irreducible quadratic factors. This process is called partial fraction decomposition, and it is used to simplify complex expressions for integration, solving equations, or analysis.Partial fraction decomposition...

Poisson's Ratio01:23

Poisson's Ratio

1.1K
Poisson's ratio is a material property that indicates their stress response. It explains the connection between the elongation or compression a material undergoes in the direction of an applied force and the contraction or expansion it experiences perpendicular to that force. When a slender bar is loaded axially, it stretches in the direction of the force and contracts laterally. Poisson's ratio is the negative ratio of this lateral contraction to the axial elongation. The negative sign...

Odds Ratio01:09

Odds Ratio

1.8K
The odds ratio (OR) is a statistical measure used extensively in epidemiology and research to quantify the strength of association between exposure and outcome across different groups. Unlike relative risk, which compares the probabilities of an event occurring, the odds ratio compares the odds of an event occurring in the exposed group to the odds of it occurring in the unexposed group. The odds, in this context, are calculated as the probability of the event happening divided by the...

Area of Science:

  • Magnetic Resonance Imaging (MRI)
  • Diffusion-Weighted Imaging (DWI)
  • Image Reconstruction Techniques

Background:

  • Readout segmentation of long variable echo-trains (RESOLVE) offers reduced distortion in MRI compared to single-shot echo planar imaging.
  • However, RESOLVE's extended imaging time necessitates acceleration techniques.
  • Readout partial Fourier (RPF) is a method to shorten imaging time by undersampling k-space.

Purpose of the Study:

  • To investigate the impact of the readout partial Fourier (RPF) method on apparent diffusion coefficient (ADC) values and image uniformity in RESOLVE MRI.
  • To evaluate signal intensity, noise, and signal-to-noise ratio (SNR) as factors influencing ADC and uniformity.
  • To observe image artifacts associated with RPF implementation.

Main Methods:

  • Implementation of the readout partial Fourier (RPF) technique within the RESOLVE imaging sequence.
  • Acquisition of diffusion-weighted imaging (DWI) data at varying RPF acceleration factors.
  • Quantitative analysis of apparent diffusion coefficient (ADC) values, image uniformity, signal intensity, noise, and signal-to-noise ratio (SNR).
  • Qualitative assessment of image artifacts.

Main Results:

  • A decrease in the data acquisition ratio due to RPF led to an increase in apparent diffusion coefficient (ADC) values.
  • Image uniformity was found to decrease as the data acquisition ratio was reduced by RPF.
  • Specific artifacts were observed and documented, correlating with the degree of RPF undersampling.

Conclusions:

  • Readout partial Fourier (RPF) significantly affects ADC quantification and image uniformity in RESOLVE MRI.
  • The trade-off between accelerated imaging time and quantitative accuracy necessitates careful consideration.
  • Specialized indices or correction methods may be required for accurate ADC mapping when employing RPF in RESOLVE sequences.
