13. High frequency ultrasound with color Doppler in dermatology
Abstract: Ultrasonography is a method of imaging that classically is used in dermatology to study changes in the hypoderma, as nodules and infectious and inflammatory processes. The introduction of high frequency and resolution equipments enabled the observation of superficial structures, allowing differentiation between skin layers and providing details for

14. Blood flow velocity in monocular retinoblastoma assessed by color doppler
OBJECTIVE: To analyze the flow of retrobulbar vessels in retinoblastoma by color Doppler imaging. METHODS: A prospective study of monocular retinoblastoma treated by enucleation between 2010 and 2014. The examination comprised fundoscopy, magnetic resonance imaging, ultrasonography and color Doppler imaging. The peak blood velocities in the central retinal

15. Suture granuloma after orchiectomy: sonography, doppler and elastography features
ABSTRACTSuture granuloma is a mass forming benign lesion that develops at the site of surgery as a foreign body reaction to non-absorbable suture material. We present a case of suture granuloma that developed at the inguinal region after orchiectomy, and define the sonography, color Doppler sonography and real-time ultrasound elastography findings in correla

16. Avaliação da artéria subclávia direita na ecografia do primeiro trimestre
OBJETIVO: Avaliar a artéria subclávia direita durante a ecografia do primeiro trimestre, descrever a técnica para a sua avaliação e, em caso de identificação de artéria subclávia direita aberrante (ARSA), determinar sua associação com alterações cromossómicas e/ou malformações cardíacas e sua orientação. MÉTODOS: Estudo prospectivo que c

17. Is quantitative diffusion-weighted MRI a valuable technique for the detection of changes in kidneys after extracorporeal shock wave lithotripsy?
Objective The aim of this study was to evaluate the capability and the reliability of diffusion-weighted imaging (DWI) in the changes of kidneys occurring after extracorporeal shock wave lithotripsy (ESWL) treatment for renal stones. Materials and Methods A total of 32 patients who underwent ESWL treatment for renal stone disease between June and December 2

18. In-office bleaching effects on the pulp flow and tooth sensitivity – case series
Laser Doppler flowmetry (LDF) is a noninvasive method capable of evaluating variations in pulp blood flow (PBF) and pulp vitality. This method has thus far not been used to assess changes in blood flow after in-office bleaching. The aim of this case series report was to measure changes in PBF by LDF in the upper central incisor of three patients submitted to

19. Estudo da doença carotídea em pacientes com doença arterial periférica
Objetivo: estudar estenose das artérias carótidas nos pacientes com doença arterial periférica sintomática.Métodos: avaliaram-se consecutivamente 100 portadores de doença arterial periférica sintomática, nos estágios de claudicação intermitente, dor em repouso ou lesão trófica. A estenose carotídea foi estudada pelo eco-color-doppler, sendo co

20. High-frequency ultrasound associated with dermoscopy in pre-operative evaluation of basal cell carcinoma
The recent development of high-frequency ultrasound, associated with the improved sensitivity in color Doppler, enabled the identification of various skin structures and layers. In basal cell carcinoma, the 22 MHz frequency ultrasound permits the delimitation of tumor margins, while color Doppler, determines its vascularization. We present two cases in which

21. Elevated levels of plasma osteoprotegerin are associated with all-cause mortality risk and atherosclerosis in patients with stages 3 to 5 chronic kidney disease
Osteoprotegerin (OPG) regulates bone mass by inhibiting osteoclast differentiation and activation, and plays a role in vascular calcification. We evaluated the relationship between osteoprotegerin levels and inflammatory markers, atherosclerosis, and mortality in patients with stages 3-5 chronic kidney disease. A total of 145 subjects (median age 61 years, 6

22. Value of color doppler ultrasound, kub and urinalysis in diagnosis of renal colic due to ureteral stones
Purpose Despite the routine use of helical CT in diagnosis of renal colic, there are recent concerns regarding the radiation exposure, overuse and costs. We attempted in this retrospective study to evaluate the accuracy of ultrasound (gray-scale and color Doppler with twinkling), KUB and urinalysis in diagnosis of renal colic due to ureteral calculi presen

23. Can Doppler or contrast-enhanced ultrasound analysis add diagnostically important information about the nature of breast lesions?
OBJECTIVES: Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after micr

24. Efficacy of spermatic vein ligation in patients affected by high grade left varicocele
Purpose: To study the effect of high grade varicocele treatment in infertile patients. Materials and Methods: Seventy-five patients were selected by the following criteria: infertility persisting for more than 1 year; abnormal semen parameters; no other infertility-related disease; no obvious causes of infertility in the subject’s partner; basal eco-col
