UNLABELLED Capabilities of color and power Doppler sonography (DS) were prospectively evaluated for diagnosis of acute pyelonephritis and for prediction of scarring by comparison with 99mTc-dimercaptosuccinic acid scintigraphy (DMSA). METHODS Fifty-seven children (mean age, 5 +/- 3 y) with acute pyelonephritis were investigated by biologic testing, DS (DS 1), and DMSA (DMSA 1). Patients who w...

PURPOSE To evaluate hepatic vein flow patterns and velocities in children with acute viral hepatitis and to compare the findings to a group of healthy children, with duplex sonography. MATERIALS AND METHODS Forty children with acute viral hepatitis were enrolled in group 1 and forty healthy children were enrolled in group 2 (control group). Both groups underwent gray scale and duplex sonograp...

background: to evaluate the efficacy of color doppler ultrasound (cdus) in differentiating benign and malignant cervical lymph nodes by detecting differences in blood flow patterns. materials and methods: in this cross‑sectional prospective study, 25 untreated patients with clinical evidence of cervical lymphadenopathy were evaluated. cdus was performed for 80 cervical lymph nodes. the gray sca...

Carcinoma of the prostate gland is the most common neoplasm in men. Its treatment depends on multiple factors among which local staging plays a significant role. The basic method is transrectal ultrasound imaging. This examination enables imaging of the prostate gland and its abnormalities, but it also allows ultrasound-guided biopsies to be conducted. A conventional gray-scale ultrasound exami...

BACKGROUND Assessment of synovitis in rheumatoid arthritis (RA) is a major issue for a proper treatment administration; it has been proven that ultrasound (US) examination could be of valuable help and it is currently being investigated as a possible outcome measure for the disease. It is, though, of greatest importance to accurately establish the place of US scores among the already validated ...
