[Modern imaging of ovarian cysts].

Ultrasonography and specially vaginal endosonography is at present the technique of choice for the screening of ovary cysts. Nevertheless, the method have some limits in the study of solid lesions and big masses; that's where CT scan and MRI have good indications: CT is more reliable than US to detect fat in teratomas. CT and MRI are superior to US in determining big tumor extend because of their ability of multiplanar study. MRI permit a molecular characterisation of cystic lesions.
