[Abstract] Objective To investigate the imaging features of multi-mode and multi-parameter magnetic resonance examination in the diagnosis of placenta accreta. Materials andMethods The routine magnetic resonance imaging and multiple b value DWI were performed in 69 pregnant women with placenta accreta as placenta accreta group and 56 pregnant women without placenta accreta as control group. Placenta accreta was analyzed in routine rapid magnetic resonance imaging sequence and multiple b value DWI.Results The routine sequence showed: ①The placental patchy low signal shadow was found in both balance turbo field echo (BTFE) and single-shot fast spin-echo (SSFSE) sequences (called "sentinel black spot", with the most effective diagnosis) accounting for 49.28% (34/69);②The low signal lines of placenta and myometrium disappeared accounting for 62.32% (43/69); ③The mother's face of placenta was locally raised or wavy accounting for 73.91% (51/69); ④Anomalous increase of subfacial sinuses in placenta accounting for 71.01% (49/69). All four imaging features were statistically significant (P<0.05). DWI manifestations: placental tissue signals penetrated myometrium in 12 cases, placental nail-like, nodular protrusion into myometrium in 24 cases, there were 46 cases with localized protuberance or wavy appearance of placenta mother, at placenta accreta DWI signal increased slightly, rough 19 cases, 6 cases of signal reduction at b0 placenta implantation, all the five imaging features were statistically significant (P<0.05).Conclusions Multi mode and multi parameter MRI can provide reliable MRI features in the diagnosis of placenta accreta.
