abstract background: screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (apn). diuretic tc-99m mercaptoacetyltriglycine (mag3) scintigraphy with zero time injection of furosemide (mag3-f0) was observed to display focal parenchymal disorders. the advantages of mag3 include: lower radiation dose and short duration of the test. the aim of this stu...

Real-time cranial sonography via the anterior fontanelle was used serially over a 3- and 6-week period, respectively, to evaluate two infants who developed multicystic encephalomalacia secondary to Citrobacter neonatal meningitis. Sonographic findings included heterogeneous parenchymal echogenicity, gyral prominence, periventricular hypoechoic areas from which cystic spaces evolved, and develop...

INTRODUCTION A clinical index that discriminates disease progression independent of histopathologic features may be valuable in the best timing of biopsy. OBJECTIVE This study addresses the question if a clinical index based on cortical echogenicity, renal length to body height ratio (KL/H), and serum creatinine levels predicts renal survival. METHODS The study enrolled 154 patients. Biopsy...

INTRODUCTION The most common hereditary kidney condition is autosomal dominant polycystic kidney disease. It is the cause of 5-10% of end-stage renal disease. Its symptoms are generally late-onset, typically leading to development of hypertension and chronic kidney disease. Ultrasonography is the imaging modality of choice in its diagnosis and management. The aim of this study is to determine t...

OBJECTIVES To assess the predictive importance of ultrasonic grade 1 hyperechogenicity in potential live related kidney donors in the absence of urinary abnormalities and with perfect renal function. SUBJECTS AND METHODS The study included 34 potential living related kidney donors with this abnormality; their mean (SD, range) age was 32.7 (8.45, 23-48) years. Ten matched healthy donors with n...

AIM To estimate heritability and environmental effects on renal parenchymal thickness. METHODS In this twin study, renal parenchymal thickness of 98 Hungarian healthy adult twin pairs (68 monozygotic, 30 dizygotic) without kidney disease was measured bilaterally using renal ultrasound with Esaote MyLab 70X ultrasound machine with low-frequency curved transducers (1-8 MHz). RESULTS In both m...

Seventy-seven clinically normal children with kidneys of normal size were examined sonographically. Renal parenchymal volumes were calculated and related to age, height, body weight and body surface area; growth charts were constructed. A significant correlation was found between the renal parenchymal volume and the body somatometric parameters. The present report thus provides norms for renal ...

Cranial sonograms of six children with brain tumors (one newborn, four infants, and one 4-year-old child) are presented. In four, sonography showed a large tumor mass and displacement of adjacent structures. In two, the tumors were demonstrated as areas of abnormal brain parenchymal echogenicity without obvious mass effect. Two of the tumors were diffusely echogenic, one was primarily cystic, a...

In the neonate, ventriculitis and inflammatory infiltration of the choroid plexus usually accompany meningitis. Intracranial sonograms were reviewed from six infants referred for evaluation because of clinically suspected or confirmed ventriculitis. Findings included ventricular dilatation with irregularity of the ventricular margins and increased periventricular echogenicity. The choroid plexu...
