A novel millisecond NMR imaging method is introduced, which generalizes the principle of stopped‐pulse experiments. It has been dubbed QUEST for QUick Echo Split imaging Technique. Repeated dephasing and excitation is used to divide a primary free induction decay into an exponentially growing number of echoes. Very few gradient lobes and RF pulses already generate large numbers of echoes, so neither gradient switching speed nor RF absorption represents any real limitation. True spin echoes are easily produced.
