“…In such cases where US is indeterminate, MRI is the diagnostic imaging modality. Ectopic gestational sac is usually extra-ovarian, T1 hypointense, T2 hyperintense with ring like or dot like enhancement & surrounding hematoma (21). In our study we had an intact ectopic tubal pregnancy.…”

“…In women of reproductive age group presenting to the emergency department with bleeding PV or pelvic pain, ectopic pregnancy (EP) is a dreaded diagnosis due to associated increased morbidity & mortality (10,21). There is rising incidence of EP with increasing sexually transmitted diseases and use of assisted reproductive techniques (21).…”

Objective: Gynecological emergencies continue to be a diagnostic challenge. Although ultrasound is an excellent first line imaging modality, there are many instances where sonographic findings are indeterminate. The purpose of this study was to assess the emerging role of MRI in gynecological emergencies. Methods: 88 patients with acute pelvic pain or bleeding per vagina who underwent MRI at our imaging department between October 2012 and September 2014 were reviewed. The final diagnosis was established by surgical findings in 69 cases, endovascular intervention & biopsy in 1 respectively. The remaining 17 cases underwent follow-up MRI. Results: MRI was diagnostic in 84 (95.5%) out of 88 patients and non-diagnostic in 4 cases. The commonest gynecological emergency was pelvic inflammatory disease. Imaging findings in 71 (80.7%) patients were correlated with surgery or biopsy. The overall sensitivity and PPV of MRI in acute gynecological pathologies was 96.6% and 98.8%. Conclusion: Women presenting to the emergency room with acute pelvic pathology require prompt diagnosis to ensure timely management. MRI is superior to ultrasound in pelvic lesion characterization and is the problem solving modality when initial ultrasound is inconclusive. Our study demonstrated that MRI can play a significant role in providing accurate diagnosis in gynecological emergencies.

“…In a study of 24 patients with clinically suspected ectopic pregnancy, but inconclusive TVUS, the ectopic gestational sac was identified with MRI in 22/24 patients. While other imaging features such as T2 characteristics, T2*, and dynamic contrast enhancement were the primary tools for detection and characterization, Takehashi et al reported that 91% of implantations demonstrated a ring-like or stippled pattern of restricted diffusion [27].…”

Non-oncologic applications of diffusion-weighted imaging (DWI) in the genitourinary system

et al. 2015

Diffusion-weighted imaging (DWI) has become an increasingly used tool in abdominal and pelvic magnetic resonance imaging (MRI), primarily in the oncologic setting. DWI sequences are being added to routine MRI protocols at many institutions, and as its use has spread, more non-oncologic applications have been explored. The purpose of this article is to provide a review of DWI applications in inflammatory, infectious, autoimmune-mediated, and ischemic processes affecting the genitourinary system.

“…11 Transvaginal US demonstrates a gestational sac (GS) when hCG levels are greater than 2000 mIU/mL, 12 with a sensitivity of 69% to 99% and a specificity of 84% to 99.9%. 13 Sometimes US provides a definitive diagnosis showing an extrauterine GS with a yolk sac or embryo; more frequently, it is only suggestive of an EP showing the presence of an adnexal mass (the most common sonographic finding in EP) and pelvic free fluid. [14][15][16] The adnexal mass usually appears as a saclike ring, solid or complex (Fig.…”

Ectopic pregnancy: MRI findings and clinical utility

Abstract: MRI is an effective modality for diagnosing EP with a high detection rate of extrauterine GSs. The combination of direct and indirect signs is useful for establishing the correct diagnosis.
