Value of MRI in Differentiation of High T1 Weighted Image Signal Lesions of the Ovary in Patients with Pelvic Pain, NESREEN MOHEY, TAMIR A. HASSAN and HAITHAM A. DAWOOD
Abstract
Aim of the Work: To evaluate the value of MRI in differ-entiation of high T1 weighted image signal lesions of the ovary in patients with pelvic pain.
Material and Methods: Sixty non pregnant female patients aged 20-48 years (mean 28 years) presented with gynacological pelvic pain with indeterminate US findings of ovarian lesion. MRI pelvis was done for the 60 patients, and revealed 29 patients with high T1WI signal ovarian lesion/lesions and were included in the study. Data from both MRI and US were obtained, and the definite diagnosis was established by his-topathological examination (HPE) of the laparoscopicaly excised ovarian lesions.
Results: Final diagnosis of the 29 patients on the base of HPE of the laparoscopicaly excised ovarian lesions showing high T 1 WI signal was hemorrhagic ovarian cyst found in 17 patients (58.6%), ovarian endometrioma found in 5 patients (17.2%) and teratodermoid found in 7 patients (24. 1 %). US was conclusive in 16 patients (55.2%) while MRI was con-clusive in 28 patients (96.6%).
Conclusion: MRI is valuable tool in differentiation of high T 1 WI signal lesions of the ovary in patients with pelvic pain. The use of fat suppressed sequences helps to differentiate hemorrhagic lesions form fat containing lesions.
