“…The ultrasound diagnosis enables precise measurement of the physiological tissue structure and morphology in patients, with the diagnostic value that has been proven in diseases including adenomyosis and primary fallopian tube cancer [ 15 ]. The thickness of the muscle layer in the lower segment of the anterior uterine wall is currently a common index for the clinical diagnosis of CSP, which can fully reflect the damage situation at the uterine scar [ 16 ]. The TVA and TAS are two common modalities of ultrasound diagnosis to provide effective and important information for the treatment and prognosis of patients.…”

Objective. To compare the diagnostic efficacy among transvaginal sonography (TVS), transabdominal sonography (TAS), and 3.0 T magnetic resonance imaging (MRI) in early cesarean scar pregnancy (CSP). Methods. The clinical data of 65 patients initially diagnosed with CSP in our hospital from November 2019 to November 2020 were selected for the retrospective analysis, and all patients received TVS, TAS, and 3.0 T MRI. Taking the pathological findings as the “gold standard”, the diagnostic efficacy of different diagnostic modalities in early CSP was compared. Results. In terms of the AUC value, the result was 3.0 T MRI > TVS > TAS, and among the three diagnosis methods, 3.0 T MRI had the highest diagnostic specificity, and TVS and 3.0 T MRI had the highest sensitivity; other than intragestational hemorrhage, the detection rates of other signs of disease by TVS and TAS were significantly higher than 3.0 T MRI ( P < 0.05). Conclusion. 3.0 T MRI has better diagnostic efficacy in early CSP than TVS and TAS, while TVS and TAS work better in diagnosing uterine bleeding, plumule, yolk sac, and fetal heartbeat than 3.0 T MRI. The results are more beneficial to the guidance on selecting treatment modalities.

“…The authors reported that diffusion-and fat saturation T1-weighted images were the most accurate for the detection of EPs, picking up 100.0% and 93.3% of the 15 cases, respectively. 27 As such, the authors concluded that the use of MRI for the early diagnosis of early EPs should be considered, following negative US findings in some highly suspicious cases. 27…”

“…22 Separately, studies by Yoshigi et al 25 and Si et al 26 that aimed to determine the role of MRI in the early diagnosis of an EP reported that the use of T2-weighted imaging was highly accurate in the detection and diagnosis of EPs. Masselli et al 27 also retrospectively reviewed 150 patients with a suspected diagnosis of EP, and analysed the clinical, US, and MRI features of 15 unusual cases. The authors reported that diffusion-and fat saturation T1-weighted images were the most accurate for the detection of EPs, picking up 100.0% and 93.3% of the 15 cases, respectively.…”

Heterotopic Pregnancy after In Vitro Fertilisation and Embryo Transfer Post-unilateral Salpingectomy: A Case Report and Literature Review

2022

Heterotopic pregnancy (HP) is the simultaneous occurrence of intrauterine and ectopic pregnancies (EP). The incidence of HPs occurring spontaneously ranges from 1 in 10,000 to 1 in 30,000. However, this incidence is reported to be 1 in 100 pregnancies following artificial reproductive techniques. HP is a potentially life-threatening condition that is frequently misdiagnosed, as most diagnoses for HPs are delayed, and are only made after rupture of the EP. A high index of suspicion is, therefore, required for an accurate and timely diagnosis in order to reduce maternal morbidity and mortality, which currently stands at 1 in 200,000 live births. The most common risk factors include pelvic inflammatory disease, previous EP, assisted reproduction techniques, and ovarian hyperstimulation syndrome. Transvaginal ultrasound is the gold standard for diagnosis. As detection of an intrauterine pregnancy often leads to the mistaken exclusion of a concomitant EP, a careful transvaginal scanning of the uterus and appendages should be performed in all females of reproductive age with a positive pregnancy test and red flags in anamnesis, and/or with clinical symptoms. Routine transvaginal ultrasound at Day 27 after embryo transfer could facilitate the diagnosis of HP; however, symptoms onset before or after Day 27 are clues to early diagnosis. MRI can be very helpful in diagnosing atypical cases.

“…MRI can be a useful problem‐solving tool in patients who have an inconclusive or confounding ultrasound, particularly when there are factors affecting the ultrasound image quality, such as severe tenderness, large body habitus, excessive bowel gas, and the coexistence of ovarian mass . MRI is highly accurate in identifying the location of an extrauterine gestational sac, as it can localize the gestational sac in 93–100% of patients with an inconclusive ultrasound . Localization of the sac can help to guide management decisions in both surgical candidates and candidates for conservative treatment …”

To evaluate the feasibility of magnetic resonance imaging in predicting unusual site ectopic pregnancy: a retrospective cohort study

Abstract: • MRI is being increasingly used as a problem-solving modality in ectopic pregnancy. • MRI plays an important role in early diagnosis of unusual ectopic pregnancy. • Knowledge of MRI features in EP is essential to determinate appropriate management.
