[Comparison between isteropac and a new non-ionic contrast medium for hysterosalpingography (B-15000)].

The authors refer the results of a double blind hysterosalpingographic study with a traditional ionic contrast medium (Isteropac) and a new non-ionic one (B-15000). Both the contrast have provided good quality images, without significant intolerance. Moreover the new non-ionic contrast medium has shown an easier utero-tubal transit with a sensible reduction of the examination length and a better diagnostic result.

[Hysterography and hysteroscopy. Comparative study of 50 patients].

Hysterography and hysteroscopy have been compared in the diagnosis of endouterine benign pathology, in a group of 50 patients, complaining meno-metrorrhagia, sterility, infertility or amenorrhea. Hysterography resulted more sensible (95.3%), but less specific (86.3%) than hysteroscopy (88.8% and 95.6%).

[Peritubal adhesions and hysterosalpingography].

Hysterosalpingography cannot directly show pelvic adhesions due to pelviperitonitis, salpingitis, perimetritis or parametritis. Nevertheless this method is able to evidence an eventual tubal involvement by adhesive tissue. Located pools of contrast medium around the tubae is a well known radiological sign, but not the only nor the most frequently one observed. If the adhesions include the proximal end of the tubae, the contrast pooling may be absent. This paper analyzes, in controlled series of patients with pelvic adhesions, all the hysterosalpingographic signs which can indicate an adhesive tubal involvement.

[Prone position in hysterosalpingography].

The authors discuss the importance of prone hysterosalpingography to the aim of a careful tubal examination. Nearly all the complete or partial tubal obstructions, observed during supine hysterosalpingography, have been resolved by the simple prone position. The high percentage (91%) of successes, without pharmacological help, recommends the routine use of this simple method in all cases of doubtful tubal obstructions.

Normal uterus and uterine malformations.

The uterus is well visualized with sonography with the definition of its morphofunctional characteristics and the physiologic variations in relation to hormonal stimuli. With high frequency endovaginal and intrarectal probes, anatomical details are optimal. Color Doppler enables the study of blood flow in the pelvic vessels and supplies functional information. Hysterosalpingography is the most accurate method for the study of the uterine cavity and the evaluation of tubal patency. In the study of uterine malformations, sonography represents the procedure of first choice, able to diagnose anomalies of fusion and development of müllerian ducts. In cases of dubious or ascertained malformations, hysterosalpingography is mandatory to complete the sonographic findings.

Radiologic imaging of the fallopian tubes.

Aim of the present article is to illustrate the radiologic findings which afford the most reliable diagnosis with hysterosalpingography, in the evaluation of tubes in infertile patients. Based on the more regular anatomical patterns with details of minor anatomical variants, a common cause of infertility, the signs of the various types of tubal obstruction, are examined. The nature of the latter is not always organic: the implementation of simple albeit often resolutive technical devices as change of position or the use of more sophisticated but well-tolerated maneuvers as the interventional ones, may help detect normal patterns hidden by false (functional) obstruction. Careful analysis of tubal morphology down to the obstructed portion allows the identification of true pathologic patterns, making this exam even more valid in the diagnostic approach to the infertile patient.

Magnetic resonance imaging of pelvic endometriosis.

Endometriosis is a multifocal disease involving multiple pelvic sites. Although laparoscopy is the elective exam in the study of patients with clinically suspected endometriosis, MR imaging represents a valid noninvasive procedure for the study of areas unapproachable with laparoscopy. On MR imaging, areas of endometriosis over 1 cm in size appear homogeneously hyperintense in T1-weighted images and hypointense in T2-weighted images, while areas of endometriosis less than 1 cm in size appear hyperintense in T1-weighted images and with variable signal in T2-weighted images. Endometriosis may also appear as small cystic lesions, hyperintense in T1-weighted images. While MR imaging has some limitations in the visualization of small endometriotic implants and adhesions, it has the ability to characterize the lesions, to study extraperitoneal locations and the contents of pelvic masses. The reliability of MR imaging findings of endometriosis and the assessment of pelvic organ involvement is important for guiding subsequent laparoscopy.
