Echo Time
Description: Time in ms between the middle of the excitation pulse and the peak of the echo produced (kx=0). In the case of segmented k-space, the TE(eff) is the time between the middle of the excitation pulse to the peak of the echo that is used to cover the center of k-space (i.e.,-kx=0, ky=0).

Effective Echo Time
Description: The time in ms between the middle of the excitation pulse and the peak of the echo produced for kx
Preferred ID: DICOM:0018_9082 Type: term ID# ILX:0103680 Score: 450.34576
Effective Echo Spacing
Description: The effective sampling interval, specified in seconds, between lines in the phase-encoding direction, defined based on the size of the reconstructed image in the phase direction.

Dwell Time
Description: Actual dwell time (in seconds) of the receiver per point in the readout direction, including any oversampling. For Siemens, this corresponds to DICOM field (0019,1018) (in ns).
