Material and Methods: Between April 2022 and January 2023, patients with a histopathological diagnosis of endometrioma or endometriosis after laparoscopy were included in the study. A total of 18 patients with 30 endometrioma/endometriosis lesions were evaluated. SWI were evaluated for endometriosis foci detected in conventional MRI. Susceptibility artifacts detected in SWI but not in the conventional MRI were also noted. Results: There was no statistically significant difference between the diagnostic efficacies of SWI; T1 weighted imaging (WI) and T2 WI. While all of them had statistically significant diagnostic efficacy compared to the T2 dark spot sign. When the lesions were separated as ovarian endometrioma and deep pelvic endometriosis foci, no statistically significant difference was found between the diagnostic efficacies of the SWI sequence, while a statistically significant difference was found for the diagnostic efficacy of the T1 WI hyperintensity (p=1.000 and p=0.032, respectively). Conclusion: The diagnostic sensitivity of the SWI sequence in the diagnosis of endometrioma is similar to the fat-suppressed T1- WI hyperintensity and T2-WI hypointensity combination accepted as diagnostic criteria. The diagnostic superiority of the SWI sequence over the fat suppressed T1-WI sequence was shown in the detection of deep pelvic endometriosis foci. It was concluded that adding the SWI sequence to routine abdominal sequences and evaluating them with conventional MRI would increase the diagnostic efficacy for endometriosis.}, number={2}, publisher={Atatürk Üniversitesi}
