Introduction/Background*Ovarian cancer is usually staged surgically . Radiologic staging using CT scan along ca125 is used before surgery . Ultrasound can be used in staging before surgery related to the advances in technology and machines. Ultrasonography has some advantages over CT and MRI being a dynamic procedure during which the assessment of sliding and vascular patterns are evaluated . Vascularity can assess the nature of the lesion and the borders . We are trying here to spot the lights over this staging along with a pictorial illustration of different stages.

Methodology With advances in machines , sonography has become an accurate staging method for early and advanced gynecological tumors. Other techniques, such as computed tomography and magnetic resonance imaging, can be used as an adjunct to ultrasound in specific cases. There are still limitations in some cases In such cases, a complementary imaging method or diagnostic laparoscopy can be used. Staging of ovarian cancer is as follows. Stage 1 with ovarian involvement, stage 2 with pelvic affection, stage 3 with abdominal and nodal affection and stage 4 with extra abdominopelvic metastasis.

Result(s)*. Ultrasound is main imaging method for the differential diagnosis of benign and malignant ovarian tumors based on IOTA classification .Ultrasound can be used to detect early and locally advanced cancers along with detection of extrapelvic tumor in the abdominal cavity in the form of parietal or visceral carcinomatosis, omental and/or mesenteric infiltration. we can proceed with pattern recognition by expert , deal as malignant or apply IOTA adnex model. Secondly , we proceed with Staging of ovarian cancers .

Conclusion*Ultrasound can be used in staging ovarian cancer iota malignant cases and after pattern recognition with some limitation.
