RESUMEN
A retrospective analysis of 73 patients who had undergone X-ray mammography (XRM), automated sonomammography (ASM), and hand-held sonomammography (HSM) was performed to evaluate the clinical role of both types of sonomammography (SM) relative to XRM. The results were classified on the basis of mammographic and sonographic findings. Clinical and/or surgical proof was obtained in all 73 patients. The SM was complementary to XRM, depending on the radiographic breast density. When comparison was made between ASM (4.5 MHz) and the HSM (7.5 MHz), the pathologic condition was better identified by HSM in 86% of the cases. Moreover, in no cases was ASM better than HSM.

The evaluation of pelvic masses is routinely performed by transabdominal ultrasound. However, by placing the transducer into the vagina (the endovaginal approach), imaging resolution is improved and morphologic detail of true pelvic organs is increased. Twenty-one cases in which nonobstetrical pelvic pathology was suspected clinically were evaluated by both the endovaginal and (conventional) transabdominal approach. Each case was evaluated for efficacy of the two approaches independently and the results compared to the clinical outcome. Endovaginal scanning offered more accurate diagnostic information in 13 of the 21 cases (62%). Additional information was obtained by the endovaginal approach in seven of these 13 cases (55%). No significant difference was observed in 33%. Endovaginal ultrasound offers a diagnostic tool complementary to the transabdominal technique in the evaluation of pelvic masses in the female patient.

Endovaginal ultrasound (US) was performed in 38 pregnant women at 5-12 menstrual weeks, when the initial transabdominal sonograms had been considered inconclusive or equivocal. Clinical follow-up disclosed 32 intrauterine pregnancies (12 living, 18 spontaneous incomplete abortions, and two embryonic demises) and six ectopic pregnancies. In the 32 intrauterine pregnancies (normal and abnormal), the correct diagnosis was made in all cases with endovaginal US. The endovaginal images demonstrated the intrauterine embryo, its heart motion, and the yolk sac more clearly and more often when these structures were not apparent on the transabdominal scans. Abnormal gestational sacs were better resolved. In the six cases of ectopic pregnancy, while an extrauterine ectopic sac was visualized in only three, absence of an intrauterine gestational sac was confirmed in all cases with endovaginal scanning. No endovaginal study yielded less information than its transabdominal counterpart. Endovaginal sonography is likely to be diagnostic when transabdominal images fail to yield a definitive diagnosis in early pregnancies.
