1. Standardization of penile hemodynamic evaluation through color duplex-doppler ultrasound
RESUMO INTRODUÇÃO: A avaliação vascular da função erétil por meio da ultrassonografia com Doppler colorido do pênis (UDCP) pode trazer benefícios na tomada de decisão. Infelizmente, a falta de padronização na condução de UDCP resulta em alta variabilidade do exame, além de poder comprometer a interpretação dos resultados. OBJETIVO: Os obje

2. Comparison between peak systolic velocity of the inferior thyroid artery and technetium-99m pertechnetate thyroid uptake in differentiating Graves’ disease from thyroiditis
ABSTRACT Objectives The differentiation between the various etiologies of thyrotoxicosis, including those with hyperthyroidism (especially Graves’ disease [GD], the most common cause of hyperthyroidism) and without hyperthyroidism (like thyroiditis), is an important step in planning specific therapy. Technetium-99m (99mTc) pertechnetate thyroid scanning

3. A pancreatic hemorrhagic pseudocyst with pseudoaneurysm and the role of doppler ultrasonography: a case report
SUMMARY Hemorrhagic pseudocysts with pseudoaneurysms are a rare and fatal complication of chronic pancreatitis due to the erosion of pancreatic to peripancreatic arteries. The timing of the rupture cannot be accurately predicted, but prompt diagnosis and management are essential to prevent further bleeding. We describe the case of a 68-year-old man who prese

4. 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

5. 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

6. 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

7. 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

8. 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

9. 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

10. Ultrassonografia e CA-125 como preditores de malignidade em mulheres com tumores anexiais / Ultrasonography and CA-125 as predictors of malignancy in women with adnexal tumors
Introduction: Ovarian cancer is the deadliest gynecologic neoplasm and it is the fifth leading cause of cancer-related deaths in women. The survival rate is low, not exceeding 40% after 5 years and is directly related to tumor stage at the time of diagnosis. To date there is still no screening method that is effective at reducing mortality from this neoplasm

11. Hemodinâmica uterina avaliada por ultrassom Doppler colorido e taxa de fertilidade de vacas submetidas à IATF com sêmen analisado por sondas fluorescentes / Uterine hemodynamics assessed by color Doppler ultrasound and fertility rate of cows submitted to FTAI with semen analyzed by fluorescent probes
Após a inseminação artificial, as fêmeas apresentam reação inflamatória transitória e fisiológica, que pode resultar em alterações na vascularização uterina. A ultrassonografia Doppler colorido é uma técnica não invasiva, que vem sendo utilizada para estudar a hemodinâmica do trato reprodutivo de bovinos. Os objetivos deste trabalho foram ve

12. The role of the resistive index in Hashimoto's thyroiditis: a Sonographic pilot study in children
OBJECTIVE: The role of Doppler ultrasonography in the diagnosis of diffuse thyroid diseases is not well established. In particular, Doppler ultrasonography findings in children with Hashimoto's thyroiditis are very limited. We examined gray-scale and Doppler ultrasound findings in Hashimoto's thyroiditis in children in an attempt to understand the feasibilit
