We report a case of acute idiopathic scrotal edema (AISE) in a 4-year-old boy who presented with acute scrotal pain and erythema. The clinical features, ultrasound appearance, and natural history of this rare diagnosis are reviewed. In this report, we highlight the importance of good ultrasound technique in differentiating the etiology of the acute scrotum and demonstrate the color Doppler "Fou...

Ultrasound is a popular imaging modality for its safety and low cost. Its role in the diagnosis of breast cancer is discussed, and its performance is then compared those of mammography (gold standard) and MRI. Besides conventional B-mode and color or power Doppler ultrasound images, latest development of acoustic radiation force impulse (ARFI) and supersonic shear imaging and their application ...

BACKGROUND The aims of the present study were: to assess standard ultrasound and color-Doppler patterns for the study and characterization of salivary gland tumors; to define the improvement in the color-Doppler ultrasound image after injection of a signal amplifier (Levovist); to compare morphological and vascular aspects of the neoplasm with data obtained during postoperative histopathologica...

A 37-year-old man presented to the emergency department (ED) for palpitations, anxiety, and weight loss. Physical examination revealed a pulse of 104 beats/min, blood pressure 140/92 mmHg, respirations 12 breaths/min, and oral temperature 99 F. Neck examination was notable for a diffusely enlarged thyroid without discrete nodules. Bedside emergency ultrasound (EUS) was performed with a high fre...

Visualize extraordinary levels of detail and contrast resolution with exceptional penetration at higher frequencies even on difficult patients For the past 30 years, ultrasound has experienced dramatic changes as manufacturers strive to develop new solutions to meet the needs of clinicians. From the pioneering days of static B-scan to color Doppler and real-time imaging, each brought major dyna...

OBJECTIVES Our purpose was to investigate cervical lymphadenopathies by using color Doppler spectral analysis and power Doppler ultrasonography methods as well as B-mode ultrasound and to classify them as malignant or benign lesions and to compare the results with the histopathological findings. PATIENTS AND METHODS Sixty-nine lymph nodes of 69 patients were evaluated with color and power Dop...

We intended to compare gray-scale vs. color Doppler ultrasound findings in cold thyroid nodules. Sixty-four patients with cold thyroid nodules for whom the presumptive diagnosis of malignancy (based on isotope scan study) had been made were consecutively included. They underwent gray-scale and color Doppler sonography studies. Based on histopathologic examination of surgically removed nodules, ...

Principles of TDI Doppler echocardiography relies on detection of the shift in frequency of ultrasound signals reflected from moving objects. With this principle, conventional Doppler techniques assess the velocity of blood flow by measuring high-frequency, low-amplitude signals from small, fast-moving blood cells. In TDI, the same Doppler principles are used to quantify the higheramplitude, lo...

Objective: To prospectively assess the diagnostic performance of Doppler ultrasound and grayscale imaging for the discrimination of benign and malignant adnexal masses. Study design: Observational study. Duration: January 2002 to December 2003. Setting: Mother and Child Health (MCH) Center, Unit II, Pakistan Institute of Medical Sciences, Islamabad, Pakistan. Subjects: Patients with an adnexal ...

Advanced ultrasound technology has been a valuable tool in the assessment of placental anatomy and physiology. Con­ ventional two­dimensional (2D) sonography reveals placental morphological characteristics, 2D color Doppler can assess blood flow in the placenta, 2D power Doppler can evaluate placental vascular trees, and three­dimensional (3D) ultra­ sound gives more detailed information on the...
