American Institute of Ultrasound in Medicine Proceedings J Ultrasound Med 32(suppl):S1–S134, 2013view of the literature was performed to assess the frequency of this conditionand its association with in vitro fertilization procedures.Results—We identified >250 reported cases, most of them casereports and some series. Among the articles, 5 cases of OEP were foundin patients with a history of salpingectomy, and 4 papers reported OEPafter ICSI-ET.Conclusions—OEP may be an unexpected finding in patientswith salpingectomy; unfortunately, this condition cannot prevent OEP.Monitoring of β-human chorionic gonadotropin levels and the accuracy ofultrasonographic diagnosis allowed a conservative therapeutic strategyand proper postoperative course.1540300 Ultrasound Screening of the Dense Breast: An Analysis ofthe Costs and Benefits to Both the Patient and the PractitionerRen Tianbo, Sirisha Jasti,* Katherine Kaproth-Joslin, AviceO’Connell Radiology, University of Rochester, Rochester,New York USAObjectives—Approximately 40% of all women undergoingscreening mammography are found to have dense breasts. Unfortunately,the sensitivity and specificity of mammography are reduced in patients withdense breasts, and some research indicates that dense breasts have an increasedrisk of breast cancer development. Recent studies have suggestedthat mammography combined with screening breast ultrasound can help detectbreast cancers in patients with dense breasts. California and Connecticutare currently the only 2 states where screening ultrasound has beenapproved, and New York has recently passed a bill requiring the inclusionof breast density information sent to women after their mammogram. Thepurpose of this presentation is to review the advantages and disadvantagesof screening breast ultrasound and to analyze the feasibility of screening ultrasoundas a standard screening protocol in current radiology practice, includingboth the cost and time expenses to the patient and practitioner.Methods—In this presentation, we will review the sensitivityand specificity of screening ultrasound plus mammography. We will analyzeboth the monetary and time costs to the patient and to the practitionerassociated with screening ultrasound plus mammography vs standardmammography alone, with a close examination of what is occurring inConnecticut and California, including who is or will be paying for theseexams. Finally, we will discuss the general impact of additional ultrasoundscreening of dense breast tissue in light of the US Preventive ServicesTask Force 2009 recommendations, where even routine mammographicscreening for breast cancer is being questioned.Results—The results of our analysis as described above will bediscussed in the presentation.Conclusions—With the recent US Food and Drug Administrationapproval of an automated breast ultrasound system and the push forscreening ultrasound as a standard screening procedure in Connecticutand California, as well as the new legislation passed in New York State tonotify women of their breast density, it is necessary to understand the costsand benefits of screening ultrasound to both the patient and the practitioner,including efficacy of the procedure.1540301 Ultrasound Features of Follicular Neoplasms and UltrasoundFeatures of Follicular Neoplasms Proven to Be FollicularCarcinoma at SurgeryAnnette Ho,* Michael Davis, Annemarie Buadu MedicalImaging, University of Arizona, Tucson, Arizona USAfollicular neoplasms were reviewed to determine how often these lesionshad calcifications and/or were cystic. Thirty-three of the patients diagnosedwith follicular neoplasms subsequently underwent thyroidectomy.The surgical pathology reports were reviewed to determine how frequentthe follicular neoplasms were malignant.Results—The database included 62 patients with follicular neoplasmsafter ultrasound-guided thyroid biopsy. On ultrasound imaging, 21of 62 follicular neoplasms had cystic components, and 13 of 62 follicularneoplasms had calcifications. Four of the 33 FNB follicular neoplasmlesions were found to be malignant on surgical pathology. One was diagnosedas follicular carcinoma, 1 as papillary carcinoma, and 2 as the follicularvariant of papillary thyroid carcinoma.Conclusions—Follicular neoplasms did not often have calcificationsand were often solid. Follicular neoplasms were more often benignlesions than malignant.1540408 Advanced Ultrasound Evaluation of Carotid Plaque: Cana Combined 2-Dimensional and 3-Dimensonal UltrasoundAnalysis Provide Additional Information and Identify SignificantPlaque Characteristics Responsible for Strokes?Lysa Legault Kingstone, 1,2 * Carlos Torres, 1 Geoffrey Currie 21Diagnostic Imaging, Ottawa Hospital, Ottawa, Ontario,Canada; 2 School of Dentistry and Health Sciences, CharlesSturt University, Wagga Wagga, New South Wales, AustraliaObjectives—Using ultrasound (US) to image plaque morphologymay improve stroke prevention by identifying atherosclerotic plaquesat higher risk for cerebrovascular events and associating morphologic characteristicswith additional risk factors. This study evaluated how integratingan advanced US plaque imaging analysis adjunct to stenotic gradingidentifies vulnerable characteristics in carotid atheromatous structure.Methods—Patients with known high-grade carotid artery disease,confirmed on computed tomography (CT), and who were scheduledfor a future endarterectomy, were recruited for this study. Prior to surgery,these participants received advanced US plaque imaging to identifycombined high-risk morphologic features such as specific homogeneity,internal echo texture, ulceration, surface irregularities, intraplaquehemorrhage/lipid core, and calcification. These identified morphologicfeatures were further enhanced with the use of high-frequency and 3D reformattedimaging. We strengthened the study’s results by analyzing thecarotid US imaging findings and then correlating them with their postendartertectomyhistologic studies.Results—At the time of abstract submission, final data collectionwas not yet available; however, preliminary results indicate a highcorrelation rate, sensitivity, and specificity between the US findings andthe detailed surgical specimens.Conclusions—Applying advanced US plaque imaging to furtheridentify significant plaque characteristics responsible for strokes canprovide insight into early causative conditions of carotid atherosclerosis.This advanced imaging protocol could potentially shift the paradigm inearly carotid plaque imaging and possibly predict the onset in asymptomaticor mild to moderate plaques.1540482 Utility of 3-Dimensional Plaque Imaging in Carotid StenosisLysa Legault Kingstone, 1,2 * Carlos Torres, 1 Geoffrey Currie 21Diagnostic Imaging, Ottawa Hospital, Ottawa, Ontario,Canada; 2 School of Dentistry and Health Sciences, CharlesSturt University, Wagga Wagga, New South Wales, AustraliaObjectives—To determine how often follicular neoplasms diagnosedby ultrasound-guided fine-needle biopsy (FNB) had cystic componentsor calcifications. Also, to determine how often follicular neoplasmsdiagnosed with FNB are proven to be malignant after thyroidectomy.Methods—Two hundred thirty-one lesions in 202 patients whounderwent thyroid biopsy were reviewed. Of these, 62 were diagnosed asfollicular neoplasms by ultrasound-guided FNB. Ultrasound features ofS107Objectives—Emerging data suggest that carotid plaque morphologyand severity can significantly affect the cerebrovascular prognosis.Recent studies have reported that 3D ultrasound (3DUS) used as anadjuvant imaging technique may provide additional information in theevaluation and risk stratification of vulnerable carotid plaque. The aim ofthis study was to evaluate the utility of 3DUS in characterizing plaquefrom various degrees of stenosis.
