giant uterine leiomyomas are extremely rare neoplasms and are challenging both diagnostically and therapeutically. a 49-year-old premenopausal female presented at our department complaining of abdominal pain and distention for several years. ultrasound (us), color doppler us, abdominal computed tomography imaging after administration of contrast material, and abdominal magnetic resonance imagin...

Vascular torsion is a rare renal transplant complication which requires prompt diagnosis and surgery to salvage allograft function. We report here a case of renal allograft torsion with interesting imaging findings on unenhanced CT and color Doppler ultrasound. A 60-year-old woman with a history of pancreas and kidney transplant presented to the emergency room with nausea, vomiting, abdominal p...

Transvaginal Doppler color flow mapping was performed on 8 Japanese women (normal, 1; menopause, 2; uterine myoma, 1; endometriosis, 2; pregnant, 2). In all 8, bilateral uterine arteries and branches could be clearly identified in shades of blue and/or red. The color flows were abundant in the pregnant women. Transvaginal Doppler color flow mapping is expected to be an important diagnostic tool...

BACKGROUND AND PURPOSE Experimental and clinical data suggest that insonation of echo-contrast agents with high acoustical power produces disintegration of microbubbles, resulting in a pseudo-Doppler phenomenon called stimulated acoustic emission (SAE). The purpose of this study was to investigate whether SAE might be detected by transcranial color Doppler imaging and whether these signals migh...

BACKGROUND Doppler images of pulmonary vessels in pulmonary diseases associated with subpleural consolidations have been described. Color Doppler easily identifies such vessels within consolidations while spectral Doppler analysis allows the differentiation between pulmonary and bronchial arteries. Thus, Doppler helps in diagnosing the nature of consolidations. To our knowledge, Doppler analysi...
