Preface We are delighted to present Diagnostic Imaging: Gynecology, third edition, the most comprehensive point-of-care imaging resource for gynecologic disorders. The goal of this book is to take the wide range of wonderfully complex topics related to gynecologic imaging and simplify them into a useful and easy-to-understand reference for caretakers at any level of experience, including trainees, general radiologists, gynecology imaging specialists, and gynecologists. This has been achieved using concise, bulleted text and thoughtful grouping of pertinent disease entities by organ, including uterus, cervix, vagina/vulva, ovary, fallopian tubes, multiorgan disorders, and pelvic floor.
Our passionate team of radiologists has thoroughly updated the text and references from the successful second edition, reflecting recent advances in technology and understanding of pathologic conditions as well as changes to TNM/WHO classifications, FIGO staging, and AJCC prognostic groups. Extensive efforts have been made to revamp the already fabulous image galleries with new, high-quality, instructive cases for every entity. More than 2,300 annotated images (and an additional 840 supplemental digital images) exhibit multimodality correlation between ultrasound, sonohysterography, hysterosalpingography, MR, PET/CT, and gross pathology.
The superb radiologic images we present were only possible because of the fine work of our remarkable sonographers and CT/MR technologists. We are also fortunate to collaborate with Laura Wissler, Lane Bennion, and Richard Coombs, who are the most talented and experienced medical illustrators. They possess a rare combination of profound anatomic knowledge and an ability to generate elegant representations of complex structures. Their contributions allow those who contemplate their illustrations to quickly attain a deeper level of comprehension.
This production was especially efficient because of the cohesive efforts of our team, including the image editors (Lisa Steadman and Jeffrey Marmorstone), text editors (Arthur Gelsinger, Rebecca Bluth, Nina Themann, Terry Ferrell, and Megg Morin), graphic designer (Tom Olson), production editors (Emily Fassett and John Pecorelli), lead editor (Kathryn Watkins), and senior manager (Karen Concannon).
Our team is very proud of this work, and we are sure that this new volume will be a rich and oftenused addition to your practice’s collection of resources.

□Ifthereisfluidwithinendometrialcavity,itshould beexcludedbymeasuringeachendometriallayer separately
□Evaluatefocalendometrialthickeningormasses (colorDopplermaybehelpfultoevaluatefor vascularstalk)
□IfIUDispresent,dedicatedimaginginlongitudinal andtransverseplanesshouldbeobtained
□Acquisitionof3Dvolumewithcoronalreformatted imageisusefultoevaluateIUDposition
–Cervicalimages
□Transverseandlongitudinalimagesthroughcervix
–Insettingofpriorhysterectomy,vaginalcuffshould beevaluated
○Adnexalimaging
–Ovariesshouldbemeasuredin3orthogonalplanes
–ObtaincolorandpulsedwaveDopplerimagesof ovaries,documentingarterialandvenouswaveforms
–Measureanyabnormaladnexallesionin3planesand evaluateforDopplerflowwithinlesion
–Determineiflesionarisesfromovaryorisseparate fromovary
□GentlypresswithEVprobe;adnexallesionarising fromovarywillmovewithovary,whereas paraovarianlesionwillmoveindependentfrom ovarywithpressure
–Bladderfilling&/oremptyingcanhelpdetermine etiologyandlocationofpelviccystincaseswhere largecystismistakenforurinarybladder
–Ifovariesaredifficulttofind,obtaincoronalviewof uterinefundusandanglelaterallytoregionofbroad ligament
□Alternatively,locateiliacvasculatureinlongitudinal planeandslowlyimagetowardmidline
–Scanbetweenuterusandovariestoassessforother adnexalmasses
□Mayidentifyparaovariancysts/masses,ectopic pregnancy,ordilatedfallopiantube
□3Dultrasoundcanhelpconfirmtubularnatureof suspectedhydrosalpinx
○Posteriorcompartment/cul-de-sacimaging
–Evaluateforfreefluid
–Torusuterinusiscommonlocationforadhesionsfrom deeppelvicendometriosis;mayperform"slidingsign" betweenposterioruterusandanteriorrectum
○Inpatientswithfocaltenderness/pain,thisregionshould bethoroughlyevaluated
•Incasesofpelvicmasses,TAUSmayalsoincludeevaluation ofkidneysforhydronephrosis/hydroureter
•ForTVUSevaluation,EVprobeshouldbeslowlyandgently inserted
○Asprobeisbeinginserted,assessforvaginalwallmasses
○Scangenerallyperformedthroughanteriorvaginalwall withprobepositionedinanteriorfornix
○Ifuterusisretrovertedorretroflexed,scanmaybe performedthroughposteriorvaginalwall
○Somepatientshavepainwhencervixismanipulated,so avoidexcessprobepressure
○Inpatientswithbowelgasobscuringvisualizationof ovary,gentleabdominalpressurecandisplacebowel loopsandallowforbettervisualization
•Transperinealevaluation
○Sagittalmidlineviewsofvagina,cervix,andloweruterus areobtained
○Parasagittalviewsasindicated
○Ifperformedduringpregnancy
–Relationshipbetweeninternalcervicalosand placentalmarginshouldbeevaluated
–Measurecervixandassessforfunneling
