تصوير المدوارة الحرة لحالة الاضطراد هو عبارة عن تتابع للتصوير بالرنين المغناطيسي يستخدم حالة الاضطراد للمغنطة، ويعتمد على تتابع تدرج الصدى مع تقصير وقت التكرار.
, Steady-state free precession (SSFP) imagin … Steady-state free precession (SSFP) imaging is a magnetic resonance imaging (MRI) sequence which uses steady states of magnetizations. In general, SSFP MRI sequences are based on a (low flip angle) gradient echo MRI sequence with a short repetition time which in its generic form has been described as the FLASH MRI technique. While spoiled gradient-echo sequences refer to a steady state of the longitudinal magnetization only, SSFP gradient-echo sequences include transverse coherences (magnetizations) from overlapping multi-order spin echoes and stimulated echoes. This is usually accomplished by refocusing the phase-encoding gradient in each repetition interval in order to keep the phase integral (or gradient moment) constant. Fully balanced SSFP MRI sequences achieve a phase of zero by refocusing all imaging gradients. zero by refocusing all imaging gradients.
, 穩定態自由旋進造影(steady-state free precession, SSFP, imaging)利用到核磁共振中的一種特殊穩定態達成的造影方式，一般分類上屬於梯度迴訊家族。旋進亦稱為進動，因而在翻譯上，此技術可能有些不一樣的名字，中國大陆地区譯作穩態自由進動成像、定常态自由进动成像。
