en 29062797 <p>Background: Infertility is a common health problem requiring imaging to delineate the anatomical causes in women. Three dimensional multi-detector computed tomography hysterosalpingography (3D-MDCT-HSG) offers an easy workup for uterine, tubal and peritoneal factors.<br /> Methods: To present the spectrum of uterine, tubal and peritoneal factors on 3D- MDCT-HSG and determine its diagnostic accuracy for female factor infertility, a prospective study was conducted on 25 infertile women with non-diagnostic HSG from November 2012 to March 2014. Sixty four slice MDCT acquired the scan during pre-ovulatory phase by contrast instillation into uterine cavity. A blinded reviewer interpreted the 3D-MDCT-HSG and results were compared with final diagnosis made on hystero-laproscopy in 22 patients. Diagnostic accuracy of 3D-MDCT-HSG for various factors was expressed as sensitivity, specificity, positive and negative predictive value.<br /> Results: MDCT-HSG demonstrated definite findings in 96% of patients having non-diagnostic HSG. In this study, tubal, uterine and peritoneal abnormalities were present in 68.75%, 56% and 32% of cases, respectively. 48 tubes in 25 patients were evaluated of which 22 tubes were blocked constituting the commonest finding present in 15 (60%) patients. The sensitivity, specificity, positive predictive value and negative predictive value for uterine factors was 83.33% ,100%, 100% and 96.84%, respectively, for tubal factors 93.55%, 94.68%, 85.29% and 96.83%, respectively and for peritoneal factors 62.5%, 92%, 71.43% and 88.46%, respectively. Mean effective radiation dose was 1.76&plusmn;0.18 <em>mSv</em> in MDCT-HSG.<br /> Conclusion: 3D-MDCT-HSG can detect various factors responsible for female infertility especially tubal and uterine; in cases where HSG fails to clearly delineate the pathology.</p> Female factor, Hystero-laparoscopy, Hysterosalpangiography, Infertility, Multidetector CT 323 333 https://www.jri.ir/article/707 https://www.jri.ir/documents/fullpaper/en/707.pdf ShuchiBhattGuru Teg Bahadur Hospital, New Delhi, Indiadrshuchi@hotmail.com1701MurtazaSumbulGuru Teg Bahadur Hospital, New Delhi, India1702RajpalRajpalGuru Teg Bahadur Hospital, New Delhi, India1703GitaRadhakrishnanDepartment of Obstetrics and Gynaecology, University College of Medical Sciences, Delhi University, New Delhi, India1704
