Use of magnetic resonance imaging in evaluation of placental invasion

The MRI features of placental adhesion disorder and their diagnostic significance: systematic review

“…27 The sagittal plane at T2W is considered the best orthogonal plane to display the level and scope of invasion. 19 Because of the excellent soft-tissue resolution and multiplanar capability of MRI, the level of invasion in the majority of the included studies has been correctly identified in concordance with the pathological and surgical findings. 19 The MRI field strength in almost all included papers was 1.5 T. Three tesla has the advantage that it provides greater signal intensity, but it also has some theoretical disadvantages, such as susceptibility artefacts, dielectric effects, and chemical shift artefacts.…”

Conventional MRI features for predicting the clinical outcome of patients with invasive placenta

“…Low signal intensity bands on T2-weighted imaging appear as areas with nodular or linear disposition, extending from the uterine-myometrial surface to placenta (16,17). They represent abnormally thickened fibrous tissue or areas of fibrin deposition because of repetitive intraplacental hemorrhage.…”

“…on T2-weighted images, focal disruption of placental-myometrial interface, and placenta protrusion sign were listed as distinctive findings of placental invasion on MRI (15)(16)(17)(18). However, to the best of our knowledge, there has been no study correlating MRI features with maternal clinical outcome after UAE-assisted CS delivery until now.…”

Caesarean Scar Pregnancy: Treatment with Bilateral Uterine Artery Chemoembolization Combined with Dilation and Curettage

“…5 With the continuing growth of the trophoblastic tissue, the blood supply becomes very rich and irregular, and the bladder artery may become one of the supply arteries of the gestational sac. 16 In the present study, one patient demonstrated bladder artery staining after BUACE. In our opinion, DSA demonstrated in this case that the bladder artery had become a supply artery of the gestational sac, but there was no additional supportive evidence Although obvious arteriovenous malformations were not evident in the patients in the present study, the uterine drainage vein, often shown during the A delay in diagnosis and/or treatment of CSP can lead to uterine rupture, major haemorrhage, hysterectomy and maternal morbidity.…”
