While many reasons are not a cause for concern, there is a possibility of serious health conditions such as an ectopic pregnancy. If echo_time shrinks down, you have a transport issue to address as best you can with buffering. If echo_time is still to large, you'll need to start digging into the PHP C code.

SpletPurpose: Both measurements have drawn interest in many applications, especially in skeletal muscle studies, which have short T2 values. Multiple echo single-shot schemes have been proposed to obtain those variables simultaneously within a single scan, resulting in a reduction of the scanning time. SpletMean scan time was 131 s (125-141 s) in ZTE and 467 s (453-508 s) in UTE. ZTE images were obtained with less acoustic noise. Conclusion: Implementing ZTE as an additional sequence in routine lung MR is feasible. ZTE can provide high-resolution pulmonary structural information with better SNR and CNR using shorter time than UTE.
