In many cases, these are reported as incidental findings, but occasionally studies are ordered specifically to locate wayward devices or assess for complications related to them. This requires radiologists to be able to correctly identify a wide range of foreign bodies, recognize their expected location, and assess for any associated complications. The purpose of this article is to familiarize the reader with a variety of foreign bodies and their usual positions in the female reproductive tract as well as their associated complications, if any.\u0000\u0000Methods: A search was performed of our institutional database, Montage, to find examples of frequently encountered foreign bodies of the external genitalia, vagina, cervix, uterus, and fallopian tubes in their expected positions. Further searches were made to illustrate common complications related to each.\u0000\u0000Results: Imaging of foreign bodies including external genital piercings, tampons, menstrual cups, pessaries, contraceptive rings, brachytherapy applicators, intra uterine contraceptive devices, and internal and external tubal closure devices were compiled across multiple modalities including x-ray, CT, MRI, and ultrasound. Complications including migration, perforation, and infection were reviewed.\u0000\u0000Conclusion: Foreign bodies of the female reproductive tract are ubiquitous and should be readily recognized by radiologists. Comprehensive evaluation includes assessment for correct location and device-related complications.","PeriodicalId":132118,"journal":{"name":"Open Journal of Radiology and Medical Imaging","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130348548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several guidelines have addressed delineation of the prostate bed but with variable specification of the inferior border relative to the penile bulb or to the first CT slice distal to visible urine in the bladder neck. This work determines the correlation between the caudal aspect of the anastomosis shown by the tip of the urethrogram cone and MRI anatomy.\u0000\u0000Materials and Methods :\u0000\u0000Sixteen patients receiving adjuvant radiotherapy following prostatectomy underwent diagnostic MRI in addition to planning CT with Urethrogram. The CT Reference Slice, tip of urethrogram cone and superior aspect of penile bulb were delineated.\u0000\u0000Results:\u0000\u0000MRI clearly demonstrates the penile bulb but not the anastomosis. In these 16 patients, the tip of the urethrogram cone was a median 3.9 mm cranial to the penile bulb (range 0-10.3 mm).\u0000\u0000Conclusion: We show marked variability in the distance between penile bulb and the tip of the urethrogram cone. In all sixteen patients, placing the inferior border of the CTV 15mm cranial to the penile bulb would have failed to treat the caudal aspect of the anastomosis, a frequent site of local relapse, that cannot be reliably landmarked by any other anatomic structure. Individualizing the treatment volume to patient anatomy is the only way to ensure consistent coverage without treating a larger than necessary volume in many patients. We recommend the use of planning urethrogram to minimize the potential for geographic miss.","PeriodicalId":132118,"journal":{"name":"Open Journal of Radiology and Medical Imaging","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122234285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
