Endometriosis is a common gynaecological condition of unknown aetiology that primarily affects women reproductive age. The accepted first-line imaging modality pelvic ultrasound. However, magnetic resonance (MRI) increasingly performed as an additional investigation in complex cases and for surgical planning. There currently no international consensus regarding patient preparation, MRI protocols or reporting criteria. Our aim was to develop clinical guidelines evaluation endometriosis based...

Abstract Breast density is an independent risk factor for the development of breast cancer and also decreases sensitivity mammography screening. Consequently, women with extremely dense breasts face increased late diagnosis cancer. These are, therefore, underserved current mammographic screening programs. The results recent studies reporting on contrast-enhanced MRI as a method in provide compelling evidence that this approach can enable important reduction mortality these cost-effective....

The use of computed tomography (CT) and magnetic resonance (MR) imaging has increased tremendously in the past 2 decades. Hence, pregnant breast-feeding women, although generally healthier than population at large, are also more likely to require contrast material–enhanced imaging. When a contrast-enhanced CT or MR study is being considered for lactating patient, potential risks fetus related exposure radiation, high fields, agents must be weighed carefully against misdiagnosis due...

Approximately one-quarter of adnexal masses detected at ultrasonography are indeterminate for benignity or malignancy, posing a substantial clinical dilemma.To validate the accuracy 5-point Ovarian-Adnexal Reporting Data System Magnetic Resonance Imaging (O-RADS MRI) score risk stratification masses.This multicenter cohort study was conducted between March 1, 2013, and 31, 2016. Among patients undergoing expectant management, 2-year follow-up data were completed by 2018. A routine pelvic MRI...

Purpose To construct and undertake preliminary validation of a magnetic resonance (MR) imaging scoring system designed for use in pelvic MR performed characterization adnexal masses that were indeterminate at ultrasonography (US). Materials Methods The institutional ethics committee approved this retrospective study granted waiver informed consent. population comprised 394 women who underwent between January 1, 2008, October 30, 2010, 497 seen US. Then, chronologically divided into training...

An update of the 2010 published ESUR recommendations MRI sonographically indeterminate adnexal mass integrating functional techniques is provided. algorithmic approach using sagittal T2 and a set transaxial T1 T2WI allows categorization masses in one following three types according to its predominant signal characteristics. 'bright' due fat or blood content can be simply effectively determined combination T1W, T2W FST1W imaging. When there concern for solid component within such mass, it...

Objectives To assess the influence of gray-level discretization on inter- and intra-observer reproducibility texture radiomics features clinical MR images. Materials methods We studied two independent MRI datasets 74 lacrymal gland tumors 30 breast lesions from different centers. Two pairs readers performed three two-dimensional delineations for each dataset. Texture were extracted using softwares (Pyradiomics an in-house software). Reproducible selected a combination intra-class correlation...

We summarise here the information to be provided women and referring physicians about percutaneous breast biopsy lesion localisation under imaging guidance. After explaining why a preoperative diagnosis with is preferred surgical biopsy, we illustrate criteria used by radiologists for choosing most appropriate combination of device type sampling technique Then, describe commonly devices, from fine-needle tissue larger needles, namely core needle vacuum-assisted how mammography, digital...

Abstract Objective To provide up-to-date European Society of Urogenital Radiology (ESUR) guidelines for staging and follow-up patients with ovarian cancer (OC). Methods Twenty-one experts, members the female pelvis imaging ESUR subcommittee from 19 institutions, replied to 2 rounds questionnaires regarding techniques structured reporting used pre-treatment evaluation OC patients. The results survey were presented other authors during group’s annual meeting. lexicon was aligned American...

Abstract Purpose To evaluate the utility of dynamic contrast enhancement (DCE) MRI for distinguishing among benign, borderline and invasive epithelial ovarian tumors. Materials Methods We analyzed preoperative studies 37 patients with tumors (10 11 borderline, 16 invasive). A DCE‐MRI sequence was acquired regions interest (ROIs) were drawn in adjacent myometrium. total three patterns defined. Dynamic data parameterized using mathematical models that included amplitude (EA), time half rising...

Abstract Unilateral axillary lymphadenopathy is a frequent mild side effect of COVID-19 vaccination. European Society Breast Imaging (EUSOBI) proposes ten recommendations to standardise its management and reduce unnecessary additional imaging invasive procedures: (1) in patients with previous history breast cancer, vaccination should be performed the contralateral arm or thigh; (2) collect data for all referred services, including undergoing cancer staging follow-up examinations; (3) perform...
