113052​

Mean Transit Time​

The time required for blood to pass through a region of​

 

 

 

tissue.​

 

113053​

Pixel by pixel multiplication​

Values are derived by the pixel by pixel multiplication of​

 

 

 

two images.​

 

113054​ Negative Enhancement Integral​The area described by the baseline and the signal loss​ due to passage of contrast bolus in tissue in a perfusion​ experiment. Abbreviated NEI or N1.​

113055​ Regional Cerebral Blood Flow​The absolute flow rate of blood perfusing a region of the​Retired.​

 

 

brain as volume per mass per unit of time. The mass​

 

 

divisor may be approximated by a measurement of​

 

 

volume assuming a tissue density of 1.​

as volume per mass. The mass divisor may be​

 

 

approximated by a measurement of volume assuming a​

 

 

tissue density of 1.​

113057​

R-Coefficient​

Correlation Coefficient, r.​

113058​

Proton Density​

Values are derived by calculating proton density values.​

113059​

Signal Change​

The relative change in signal.​

113060​

Signal to Noise​

The ratio of the desired signal to the level of noise.​

113061​

Standard Deviation​

Values are derived by calculating the standard deviation​

113062​ Pixel by pixel subtraction​

Values are derived by the pixel by pixel subtraction of​

 

 

two images.​

113063​

T1​

The time constant for the decay of longitiudinal​

 

 

magnetization caused by spin-lattice relaxation. The​

 

 

inverse of the longitudinal relaxation rate constant, i.e.,​

 

 

T1 = 1/R1.​

113064​

T2*​

The time constant for the decay of transverse​

 

 

magnetization caused by a combination of spin-spin​

 

 

relaxationandmagneticfieldinhomogeneity.Theinverse​

 

 

of the transverse relaxation rate constant, i.e., T2* =​

 

 

1/R2*.​

113065​

T2​

The time constant for the decay of transverse​

 

 

magnetization caused by spin-spin relaxation. The​

 

 

inverse of the transverse relaxation rate constant, i.e.,​

 

 

T2 = 1/R2.​

113066​ Time Course of Signal​

The time course of signal.​

113067​

Temperature encoded​

Values are derived by calculating values based on​

 

 

temperature encoding.​

113068​

Student's T-Test​

Values are derived by calculating the value of the​

 

 

Student's T-Test statistic from multiple image samples.​

113069​

Time To Peak​

The time from the start of the contrast agent injection to​

 

 

the maximum enhancement value.​

113070​

Velocity encoded​

Values are derived by calculating values based on​

 

 

velocity encoded. E.g., phase contrast.​

Z-Score​

ValuesarederivedbycalculatingthevalueoftheZ-Score​

 

 

statistic from multiple image samples.​

113072​

Multiplanar reformatting​

Values are derived by reformatting in a flat plane other​

 

 

than that originally acquired.​
