| خلاصه مقاله | Introduction: To examine the importance of magnetic resonance imaging (MRI) in suspicious cases for prenatal detection of placenta accrete (PA). MRI is increasingly being used based on its superior soft tissue resolution, especially for fine visualization of the placenta in the posterior uterine wall, the placenta-uterine interface, and invasion of adjacent organs. Loss of T2 hypo intense interface, heterogeneous intraplacental sign, and intraplacental T2 dark bands were more likely to be seen in these patients. Method: All scans were performed on a 1.5 T scanner with a 6-channel phased array body coil. The patient's uterus was scanned in the transverse, sagittal, and coronal planes, using the long axis of the patient's uterus as a reference. Various scanning sequences were utilized, including T2-weighted imaging (T2WI), T2-weighted half-fourier acquisition single shot turbo spin echo (T2-HASTE), T2-weighted true fast imaging with steady-state precession (T2-TrueFISP), T1-weighted volume interpolated body examination (T1-VIBE), and diffusion-weighted imaging (DWI). In all examinations, imaging signs associated with PA were reviewed, such as myometrial thinning, loss of T2 hypointense interface, and others. MRI was able to identify the presence of PAD in all cases with 100% sensitivity and its absence with 37.5% specificity. Result: The features with the highest sensitivity were intra placental dark bands (100%), myometrial thinning/loss of interface with myometrium (100%), placental heterogeneity (75%), and uterine contour abnormality (75%). Recognizing the presence of risk factors, low-signal-intensity bands, and thinning/loss of placental–myometrial interface will aid in its analysis. Conclusion: Diagnosis of placenta accrete by MRI has good accuracy and predictive value that warrants clinical promotion. MRI plays a crucial role in the prenatal detection of placenta accrete, especially in cases where suspicious signs are present. The use of MRI can provide detailed information about the placental structure and its relationship with the uterine wall, aiding in the timely diagnosis and management of this condition. |
