The study was conducted to investigate the effect of conservative surgery of ovarian endometriomas before an ICSI cycle. Ninety-nine patients with endometriomas who were referred to an intracytoplasmic sperm injection (ICSI) cycle were enrolled in the study. The patients were prospectively randomized into two groups; group I (49 patients) underwent conservative ovarian surgery before the ICSI cycle and group II (50 patients) underwent the ICSI cycle directly. The stimulation was started 3 months after the operation in group I and directly in group II. In the ovarian surgery group, stimulation was significantly longer (14.0 days in group I and 10.8 days in group II; P = 0.001), total recombinant FSH dose was significantly higher (4575 IU in group I and 3675 IU in group II; P = 0.001), and mean number of mature oocytes was significantly lower (7.8 in group I and 8.6 in group II; P = 0.032). There was no difference in terms of fertilization (86% in group I and 88% in group II), implantation (16.5% in group I and 18.5% in group II) and pregnancy rates (34% in group I and 38% in group II). Ovarian surgery resulted in longer stimulation, higher FSH requirement and lower oocyte number, but fertilization, pregnancy and implantation rates did not differ between the groups.

Purpose: To evaluate the contribution of MRI to ultrasound (US) in the diagnosis of fetal anomalies. Materials and Methods:After informed consent and institutional review board approval, concomitant US and MR imaging were performed for 184 fetuses with suspected anomalies in university hospital. Postnatal final diagnoses were obtained for 183 anomalies in 151 fetuses either by radiological examination, surgery, autopsy, or inspection. The prenatal US and MR diagnoses were compared with respect to postnatal diagnoses. Sign test was used to determine the statistical significance.Results: Both ultrasound and MR imaging correctly diagnosed 93 (50%) cases and failed in 12 (7%) cases. Ultrasound was superior in 7 (4%) cases. MR imaging was superior in 71 (39%) cases (P < 0.001). MR contributed to the prenatal diagnosis by the confirmation of the suspected US diagnosis in 13%, by demonstration of additional findings in 31% and by changing the diagnosis in 56% of the cases. The contribution rates were 55% for the central nervous system (CNS) (P < 0.001), 44% for thorax (P ¼ 0.016), 38% for gastrointestinal system (GIS) (P ¼ 0.031) and 29% for genitourinary system (GUS) (P ¼ 0.003) anomalies. In facial, cardiac and extremity-skeletal system anomalies, there was not a significant contribution of MR imaging over US.Conclusion: MR imaging can be used as an adjunct to US in the prenatal diagnosis of fetal anomalies of not only the CNS but also the non-CNS origin especially those involving the GIS, GUS and thorax. ULTRASOUND (US) IS the standard and primary modality used for the imaging of the fetus. It is widely available, easy to apply, cost-effective, safe for the fetus and allows real-time imaging. However, it has some limitations. Especially in case of oligohydramnios, large maternal body habitus and inappropriate fetal position, its effectiveness reduces. Also in the evaluation of some body parts and complex pathologies, the results of US might be unclear (1,2). In such cases, MR imaging is being increasingly used as a complementary imaging modality.Magnetic resonance imaging has the potential to improve diagnostic accuracy of the prenatal imaging and facilitate the pregnancy management (3-5). It offers a high spatial, temporal, and contrast resolution, which makes the detailed study of fetal pathologies possible. To date, it has not been shown that MR imaging has any adverse effects on the fetal growth or development (2,6).Multiple studies have up to now been published to compare the effectiveness of the prenatal US and MR imaging. These studies showed that MR imaging provides additional information to US in 36% to 57% of the cases (3,4,7,8). Although this effect has been well-established for CNS anomalies, it has not been well-documented for non-CNS anomalies. Additionally, there were some important limitations of these previous studies. In most of these studies, the comparison of the imaging methods had been made without postnatal correlation and MR results had been accepted as the gold-standard. Secondarily, in most...

Extrahepatic abdominal hydatid lesions have nearly identical imaging features, including the presence of cyst wall calcification, daughter cysts, and membrane detachment. The combinations of radiologic and serologic tests especially in patients living in the endemic areas contribute to the diagnosis. Despite their rarity, being familiar with the spectrum of radiologic findings in these unusual sites is helpful to improve diagnostic accuracy.
