Ovarian ca. Ct is not very sensitive in early stages , pelvic ultrasound or trans vaginal us is far better.
Ovarian CA detection. Ultrasound examination (uss) has a higher sensitivity of detecting ovarian cancer (93%) compared to a ct scan (63%). Although a ct scan could miss it 37% of the time, it is more likely to be correct (87%) to tell that a mass is ovarian cancer compared to ultrasound (42%). A tumor marker test in the blood (ca125) may also help in the diagnosis if the uss or ct is abnormal.
