Abstract
PURPOSE Real-time virtual sonography (RVS) allows displaying and synchronizing real-time US and multiplanar reconstruction of MRI images. The purpose of this study was to evaluate the feasibility and ability of RVS to assess adenomyosis since literature shows US itself has a reduced diagnostic accuracy compared to MRI. MATERIALS AND METHODS This study was conducted over a 4-month period (March-June 2015). We enrolled in the study 52 women with clinical symptoms of dysmenorrhea, methrorragia and infertility. Every patient underwent an endovaginal US examination, followed by a 3T MRI exam and a RVS exam (Hitachi HI Vision Ascendus). The MRI image dataset acquired at the time of the examination was loaded into the fusion system and displayed together with the US images. Both sets of images were then manually synchronized and images were registered using multiple plane MR imaging. Radiologist was asked to report all three examinations separately. RESULTS On a total of 52 patients, on standard endovaginal US, adenomyosis was detected in 27 cases: of these, 21 presented diffuse adenomyosis, and 6 cases focal form of adenomyosis. MRI detected adenomyosis in 30 cases: 22 of these appeared as diffuse form and 8 as focal form, such as adenomyoma and adenomyotic cyst, thus resulting in 3 misdiagnosed cases on US. RVS confirmed all 22 cases of diffuse adenomyosis and all 8 cases of focal adenomyosis. CONCLUSIONS Thanks to information from both US and MRI, fusion imaging allows better identification of adenomyosis and could improve the performance of ultrasound operator thus to implement the contribution of TVUS in daily practice.

Abstract
The role of imaging after surgery is pivotal to drive clinical management of early and/or late onset complications. Most frequently used imaging technique after pelvic surgery is Ultrasound (US), Magnetic Resonance Imaging (MRI) and Computed Tomography (CT). While Ultrasound is a standard procedure, using grey scale and/or colour Doppler evaluation, MRI and CT scan protocols should be derived on the basis of the specific indication of the exam. Correct evaluation of female pelvis after gynaecologic surgery, having in mind the most frequent complications, is based on the correct use of the instruments and on the experience of the examiner, who should be aware of the history of the patient, type of surgery and clinical symptoms for which the exam is required; the clinician should be aware of the possibilities and limits of the different techniques, in order to choose the most appropriate imaging modality and promptly make a correct diagnosis.

Abstract
Congenital heart disease is one of the most frequent prenatal malformation representing an incidence of 5/1000 live births; moreover, it represents the first cause of death in the first year of life. There is a wide range of severity in congenital heart malformations from lesions which require no treatment such as small ventricular septal defects, to lesions which can only be treated with palliative surgery such as hypoplastic left heart syndrome. A good prenatal examination acquires great importance in order to formulate an early diagnosis and improve pregnancy management. Nowadays, echocardiography still represents the gold standard examination for fetal heart disease. However, especially when preliminary ultrasound is inconclusive, fetal MRI is considered as a third-level imaging modality. Preliminary experiences have demonstrated the validity of this reporting a diagnostic accuracy of 79%. Our article aims to outline feasibility of fetal MRI in the anatomic evaluation, the common indication to fetal MRI, its role in the characterization of congenital heart defects, and at last its main limitations.

Abstract
INTRODUCTION Endometriosis represents an important clinical problem in women of reproductive age with high impact on quality of life, work productivity and health care management. The aim of this study is to define the role of 3T magnetom system MRI in the evaluation of endometriosis. MATERIALS AND METHODS Forty-six women, with transvaginal (TV) ultrasound examination positive for endometriosis, with pelvic pain, or infertile underwent an MR 3.0T examination with the following protocol: T2 weighted FRFSE HR sequences, T2 weighted FRFSE HR CUBE 3D sequences, T1 w FSE sequences, LAVA-flex sequences. Pelvic anatomy, macroscopic endometriosis implants, deep endometriosis implants, fallopian tube involvement, adhesions presence, fluid effusion in Douglas pouch, uterus and kidney pathologies or anomalies associated and sacral nervous routes were considered by two radiologists in consensus. Laparoscopy was considered the gold standard. RESULTS MRI imaging diagnosed deep endometriosis in 22/46 patients, endometriomas not associated to deep implants in 9/46 patients, 15/46 patients resulted negative for endometriosis, 11 of 22 patients with deep endometriosis reported ovarian endometriosis cyst. We obtained high percentages of sensibility (96.97%), specificity (100.00%), VPP (100.00%), VPN (92.86%). CONCLUSION Pelvic MRI performed with 3T system guarantees high spatial and contrast resolution, providing accurate information about endometriosis implants, with a good pre-surgery mapping of the lesions involving both bowels and bladder surface and recto-uterine ligaments.

Abstract
OBJECTIVE To establish if a correlation exists between apparent diffusion coefficient (ADC) values, obtained by diffusion-weighted imaging (DWI), and placental aging. METHOD The study is divided into a retrospective phase and a prospective one.In the first phase, 145 pregnant women underwent fetal magnetic resonance imaging (MRI) for suspected disorders in several organs. We performed DWI (b value 0, 200 and 700 s/mm(2)) in all the fetuses, evaluating the patients in whom the whole placenta was visible.In the prospective phase, 50 women (52 fetuses) underwent MRI. We performed, in the same patient, two echo-planar sequences with b values of 0, 200 and 700, and 50, 200 and 700 s/mm(2), including the whole placenta.The ADC maps were calculated for all fetuses, divided into three groups based on gestational age (GA): group I: 20-26 weeks' gestation, II: 27-33, III: 34-40. RESULTS In the retrospective phase, ADC values had a range from 1 to 2.4 mm(2)/s, showing a significant correlation between ADC values and GA.ADC values obtained by DWI with b value 0, 200 and 700 s/mm(2) had a range from 0.8 to 2.5 mm(2)/s, with an inverse correlation between ADC values and GA, whereas the ADC values with b value 50, 200 and 700 s/mm(2) did not show any statistical correlation (range: 1.5-1.7 mm(2)/s). CONCLUSION DWI with ADC maps can not be considered markers for placental aging because they are affected by perfusional and circulatory motion.

Abstract
Data literatures report numerous association between giant congenital nevus and development alteration; only two cases describe its coexistence with thyroid disorders. However, we report the association of papillary thyroid cancer and giant congenital nevus. Papillary thyroid cancer is the most common differentiated thyroid cancer and has high prevalence in young women. In this paper we report: the case of a 18 years-old woman, affected by giant congenital melanocytic nevus on her back, who came to our observation because of one month of fever and increased volume of latero-cervical lymph nodes. Negative serologic tests allowed us to exclude lymphoma and mononucleosis. Because of the high risk (6%) that giant congenital melanocytic nevi could transform into malignant melanoma, we performed an ultrasound examination (US) of the cervical lymph nodes. The examination extended to the thyroid gland enabled us to visualize the same parenchyma alteration in both thyroid gland and lymph nodes. At last, fine-needle percoutaneus aspiration on thyroid lesion confirmed the presence of papillary carcinoma. In our case, thank to the optimal visualization of the parenchyma structure, US was diriment allowing a diagnosis of primitive thyroid lesion with an involvement of all lymph nodes in the neck. This findings legitimate the role of US as an accurate, noninvasive, radiation free and low-cost imaging technique in detecting differential diagnosis in the cervical lymphadenopathy, as well in preoperative staging thyroid carcinoma.
