Two-dimensional and three-dimensional imaging of uterus and fallopian tubes in female infertility.

Noninvasive imaging techniques play an important role in the female infertility diagnostic algorithm. In this review article, a description of the diagnostic performance and potential clinical value of both computerized tomographic virtual hysterosalpingography (CT-VHGS) and magnetic-resonance virtual hysterosalpingography (MR-VHSG) is made, describing for both techniques, to guarantee the best possible diagnostic outcome, patient preparation and normal and principal pathologic findings. Both noninvasive diagnostic imaging modalities improve the diagnostic confidence in identification of the specific cause of female infertility. These procedures are well tolerated and can be performed without tenaculum and sedation. The combined analysis of all the imaging data offers the gynecologist a wide information spectrum, enabling a better therapeutic decision. CT-VHSG and MR-VHSG are consistent diagnostic imaging modalities for the evaluation of the female reproductive system, with an excellent diagnostic performance compared with traditional diagnostic exams and allowing a comprehensive assessment of the female reproductive system.

[Interest of multidetector CT virtual hysterosalpingography in the diagnosis of utero-peritoneal fistulas about 4 cases]. / Intérêt de l'hystéroscanner dans le diagnostic de la fistule utéro-péritonéale à propos de 4 cas.

We report four cases of uterine fistula found with the multidetector CT virtual hysterosalpingography. Patients were received for suspicious of a utero-peritoneal fistula at hysterosalpingography. They were young people at childbearing age (average age of 33 years), multigravidae, two of whom were nulliparous, one primiparous and one multiparous. We noted a history of voluntary interruption of pregnancy by curettage and a cesarean section. For the opacification, we used the classic hysterography standard equipment by means of 1/5 diluted iodine with saline solution as contrast. The multidetector CT virtual hysterosalpingography revealed small uterine perforations including three which were located in uterine posterior face at cervico-isthmic area and corporeal area, bringing about a utero-peritoneal fistula. The multidetector CT virtual hysterosalpingography is a simple and powerful technique for the diagnosis of utero-peritoneal fistula. It is convenient and then deserves an important place in the evaluation of uterine fistula.

Histerosalpingografía virtual por TC multidetector de 64 filas: hallazgos en 2.500 pacientes / 64-Row multidetector CT virtual hysterosalpingography: findings in 2500 patients

Objective. To depict typical features of virtual hysterosalpingography (VHSG) in infertile patients. Material and methods: 2500 VHSG performed using a 64-row MDCT were evaluated. Results: Cervical abnormalities visualized corresponded to parietal irregularities (21 percent); thickened folds (9 percent); polyps (11 percent); diverticula (5 percent); cervical strictures (8 percent), and synechiae (1.5 percent). At the level of uterine cavity, polyps (44 percent); submucous myomas (8 percent); intramural and subserosal fibroids (11 percent); synechiae (10 percent); malformations (10 percent); adenomyosis (4 percent), and cesarean section scar (3 percent). Unilateral hydrosalpinx (7 percent) and bilateral hydrosalpinx (2 percent). Tubal obstruction was reported in 6 percent of cases. The average radiation dose was 0.94 mSv. Eighty-four percent of the patients reported mild pain or no postoperative discomfort. Conclusions: The virtual hysterosalpingography allowed a proper assessment of the internal genital organs, providing useful diagnostic information on infertility and other gynecological disorders. It constitutes a virtually painless, low-dose radiation technique, besides being well tolerated by patients.

Objetivo. Ilustrar los hallazgos característicos de la histerosalpingografía virtual (HSG-V) en pacientes en estudio de infertilidad. Material y métodos: Se evaluaron 2500 HSG-V efectuadas con un equipo de TCMD de 64 filas. Resultados A nivel del cuello se visualizaron irregularidades parietales (21 por ciento); pliegues engrosados (9 por ciento); pólipos (11 por ciento); divertículos (5 por ciento); estrechez (8 por ciento; y sinequias (1,5 por ciento). A nivel de la cavidad: pólipos (44 por ciento); miomas submucosos (8 por ciento); intramurales y subserosos (11 por ciento); y sinequias (10 por ciento); malformaciones (10 por ciento); adenomiosis (4 por ciento); cicatriz de cesárea (3 por ciento). Hidrosalpinx unilateral (7 por ciento) y bilateral (2 por ciento); obstrucción tubaria en el 6 por ciento de los casos. La dosis de radiación promedio fue 0.94 mSv. El 84 por ciento de los pacientes refirieron disconfort leve o ausente. Conclusiones: La HSG-Virtual permitió una adecuada evaluación de los órganos genitales internos, brindando información diagnóstica útil en infertilidad y otros desórdenes ginecológicos. Es una técnica poco dolorosa, bien tolerada por las pacientes y con baja dosis de radiación.
