25 Although color Doppler ultrasonography has been used to evaluate testicular blood flow in 26 many species, very little has been done in goat. Eight male Shiba goats were exposed to a 27 single intramuscular injection of either gonadotropin-releasing hormone (GnRH group; 28 1μg/kg BW) or human chorionic gonadotropin (hCG group; 25 IU/kg BW). Plasma 29 testosterone (T), estradiol (E2), and inh...

Transcranial Doppler ultrasonography has been used to detect microemboli in the middle cerebral artery during orthopedic surgery. We conducted a comprehensive systematic literature review of transcranial Doppler ultrasonography in orthopedic surgery to evaluate its status in this setting. Fourteen studies were selected for qualitative analysis. The highest number of patients studied was 45; emb...

OBJECTIVES To analyze the nasal superficial arterial vasculature and to compare these anatomic findings with the results of ultrasonography Doppler investigations to evaluate nasal blood flow in physiological and pathologic conditions. METHODS We performed 40 ultrasonography Doppler investigations in patient volunteers, 20 facial anatomic dissections in fresh cadavers, and a review of the lit...

Pulmonary sequestration is a rare pulmonary parenchymal anomaly. The localization of the aberrant artery and its relation with sequestration are of importance in the process of diagnosis in the preoperative period. The feeding artery can be identified by color Doppler ultrasonography. We report two cases of pulmonary sequestration in two adolescents, aged 11 and 13 years old, and this report do...

Penile Mondor's disease is a thrombophlebitis of the superficial dorsal vein of the penis. It is a rare clinical diagnosis and generally resolves spontaneously. A simple physical examination is sufficient for diagnosis but color Doppler ultrasonography is often carried out as a further investigation. We describe two patients who developed priapism due to penile Doppler ultrasonography which was...

Background: Morbidly adherent placenta can be diagnosed prenatally by different modalities. 2D, 3D multi-slice Doppler ultrasound and MRI have emerging roles in prenatal diagnosis of morbidly placenta, but histopathological is the gold standard.Aim work: To detect accuracy over 2D-Doppler accreta relation to postpartum histopathology intrapartum findings.Patients Methods: This study was conduct...

The patient was a 19-year-old man who was examined due to persistent penile erection, which appeared following a blow to the perineal region during work. Color Doppler ultrasonography of the corpora cavernosa revealed a cavity in one part of the cavernous artery that suggested a blood leak, and a diagnosis of high flow type priapism due to trauma was made. Bilateral internal pudendal arteriogra...

OBJECTIVES To observe the phenomenon of human ejaculation dynamically using color Doppler ultrasonography. METHODS Human ejaculation was observed using transrectal color Doppler ultrasonography in a healthy man and a patient with retrograde ejaculation. Ejaculation was induced manually with audiovisual sexual stimulation. The ejaculatory phenomenon was analyzed and compared with that of retro...
