BackgroundClassifying uterine fibroid using the International Federation of Gynecology and Obstetrics (FIGO) classification system assists treatment decision-making and planning. This study aimed to study whether different fibroid locations…

BACKGROUND: Primary epithelial ovarian carcinoma is sub-classified into serous, mucinous, endometrioid and clear cell subtypes. Neoadjuvant chemotherapy has become an alternative treatment option past several years, as serous carcinoma, the…

OBJECTIVE: Although mural nodules are considered to be the most important hallmark in the recognition of ovarian cancers accompanied with endometriotic cysts, benign neoplasms and even inflammatory diseases can show similar MRI findings. We…

To assess the usefulness of fat-saturated magnetic resonance (MR) imaging in detecting small endometrial implants, 258 pigmented lesions of endometriosis from 80 consecutive patients with histopathologically diagnosed pelvic endometriosis w…

Endometriosis may be the precursor of clear cell or endometrioid ovarian cancer. In this review, we focus on the prevalence of endometriosis in ovarian cancer and related clinical and epidemiological issues. According to 15 published report…

OBJECTIVE: To determine whether magnetic resonance imaging (MRI) and serum levels of CA-125 can be used to evaluate patients with endometriomas before initiating medical treatment. DESIGN: Comparative study before and after medical treatme…

To determine whether the cyst fluid characteristics of endometrioma can be evaluated by magnetic resonance imaging (MRI), 36 endometriomas obtained from 24 patients (age range 21-43 years; mean 34 years) were studied. MRI was performed < 2 …

We evaluated the usefulness of magnetic resonance imaging (MRI) for assessing the response of patients with endometriomas to medical therapy. MRI was performed before and after treatment in 20 consecutive patients with at least one endometr…

It is difficult to distinguish a small endometrial implant from adipose tissue by magnetic resonance imaging (MRI). I assessed the usefulness of fat saturated MRI in detecting small endometrial implants by comparing it with conventional MRI…

Preoperative MRI using fat-saturation technique was performed in a patient with endometriosis. Endometrial implants as small as 3 mm were accurately diagnosed by MRI. The fat-saturation technique is useful for diagnosing small endometrioma.
