Abstract：Objective To evaluate the application value of the fast magnetic resonance imaging technique
in the diagnosis of placenta previa. Methods 25 patients diagnosed with placenta previa underwent the
single shot fast spin echo (SSFSE) sequence and fast imaging employing steady state acquisition (FIESTA)
sequence scanning. The MRI features and clinic appearances of these 25 cases were analyzed. Results One
out of the 25 cases was marginal placenta previa, 6 cases were partial placenta previa, 18 cases were complete
placenta previa. Nine cases were placenta previa complicated with placenta accrete: 3 out of the 9 cases
were placenta adhesion, 5 of 9 were placenta increta, 1 of 9 was placenta penetration. MRI could show the
relationship between the placenta and the internal cervical orifices straightly. The linear low signal intensity of
the myometrium was discontinued in the cases complicated with placenta accrete, relatively high signal of the
placenta intruded into the myometrium from the discontinued place. Conclusion The fast MRI technique has
high clinical application value in the diagnosis of the placenta previa and placenta accrete.
