“…Acquaintance with the normal and abnormal findings of the anterior uterine wall is of critical importance for radiologists in this era of ever-increasing caesarean sections. 13 An oval or triangular area of hypoattenuation, which represents edema, can be seen in the myometrium in the anterior lower uterine segment 5 ( Fig. 14 ).…”

“…A healed cesarean scar appears as a narrow transverse line in the anterior lower uterine segment, best evaluated in the sagittal section. 13 At the level of the scar, thinning and retraction of the anterior myometrium creates wedge-shaped defects which causes distortion of the tissues adjacent to the scar and may give “hourglass” shape on sagittal views. 13…”

Purpose This article aims to review the pertinent anatomy and the incidental abnormalities involving the female genital tract on multidetector computed tomography (MDCT) through a pictorial review. Methods The review is based on critical analysis of the existing literature as well as our experience in dealing with incidental lesions involving the female genital tract. Results The lack of awareness regarding the normal appearances of the female pelvis on MDCT can puzzle the inexperienced radiologist and create management dilemmas for the treating clinician. It is important for radiologists to recognize normal appearances of the female genital tract on MDCT to prevent misinterpretation as pathology. The identification of incidentalomas of the female genital tract on CT can further guide whether additional workup is required or not. This pictorial review familiarizes radiologists with the normal appearances of the female genital tract on MDCT and a few common incidentalomas. Conclusion It is imperative for a clinical radiologist to be familiar with the anatomy and common incidental lesions involving the female genital tract.

“…e MRI images based on the DDID algorithm predicted that the PF support was more serious and worse. At the same time, it has to study the early change experience of vaginal support for the women after delivery, which can provide important information to guide future prevention work [7][8][9]. e segmentation parameters and denoising performance on the MRI image of DDID algorithm were compared with those of GF and NLM algorithms.…”

This study was to explore the denoising and segmentation effect of dual-domain image denoising (DDID) algorithm, and the Galois field (GF) and nonlocal means (NLM) algorithms were introduced for comparative analysis. 40 primiparas in the hospital from January 2018 to January 2020 were divided into an experimental group (caesarean section (CS), group E) and a control group (vaginal delivery (VD), group C). The peak signal-to-noise ratio (PSNR) and segmentation parameters of DDID algorithm were compared with GF algorithm and NLM algorithm. It was found that the DDID showed higher overall accuracy (OA) and lower false positive rate (FPR) and false negative rate (FNR). The PSNR of DDID was higher than the other two algorithms. GF algorithm showed the highest edge retention index (ERI). The incidence of pelvic organ prolapse (POP) in group E and group C was 9/20 (45%) and 5/20 (25%), respectively, with extreme difference ( P < 0.05 ). Evaluation of the effects of delivery on the pelvis of primiparas with MRI three-dimensional (3D) reconstructed images based on the optimized DDID showed a superior and stable denoising effect and good segmentation, so it was worthy of clinical promotion and application.

“…It is worth mentioning at this point that there is no general consensus in the literature as far as naming of changes in the uterus after C-section is concerned, with interchangeably used terms: scar, scar defect, deficient cesarean scar, dehiscence, niche, isthmocele, pouch, diverticulum [10,11,19,20].…”

“…There is a long list of possible maternal and fetal complications related to the uterine scar after C-section, including uterine scar dehiscence, uterine rupture, abdominal and pelvic adhesions, uterine synechiae, ectopic pregnancy, anomalous location of the placenta, placental invasion, and-rarely-vesicouterine or uterocutaneous fistulas [9,10]. Other maternal complications include (chronic) pelvic pain, (chronic) incision site pain, dysmenorrhea, abnormal vaginal bleeding, endometriosis, and reduced future fertility [11].…”

The rate of Cesarean sections (C-sections) in Poland increased from 21.7% in 2001 to 43.85% in 2017 even though the Polish Society of Gynecologists and Obstetricians highlights the negative consequences of C-section for both mother and child and recommends to make every possible effort to reduce its percentage, following the World Health Organization recommendations. There is a long list of possible complications related to the uterine scar after C-section, including uterine scar dehiscence, uterine rupture, abdominal and pelvic adhesions, uterine synechiae, ectopic pregnancy, anomalous location of the placenta, placental invasion, and-rarely-vesicouterine or uterocutaneous fistulas. Ultrasound (US) remains the first-line modality; however, its strong operator-and equipment dependence and other limitations require further investigations in some cases. Magnetic resonance imaging (MRI) is the second-line tool which is supposed to confirm, correct, or complete the sonographic diagnosis thanks to its higher tissue resolution and bigger field of view. This article will discuss the spectrum of C-section complications in the MR image-rich form and will provide a systematic discussion of the possible pathology that can occur, showing comprehensive anatomical insight into the pelvis after C-section thanks to MRI that facilitates clinical decisions.
