Abstract
Improved T2 values and signal to noise ratio obtained by magnetic resonance image synthesization. Each measured echo signal intensity is divided by a correcting factor that is a function of the echo number to obtain corrected echo signal intensity. A characteristic curve is best fitted to the corrected intensity values and the intensity values of the curve are used.
