Agenesis of the corpus callosum is associated with a wide range of neuropsychiatric symptoms. Cranial MRI confirms the diagnosis. We report a case of a 13-year-old boy with global developmental delay, mental retardation as well as neurological and psychiatric symptoms but without symptoms of ADHD who is unable to cope with school demands.

- - The study investigates the relationship between delayed tissue tracer transit (TTT) of (99m)Tc-MAG3 and functional decline in piglets with surgically induced hydronephrosis, finding that delayed TTT correlates with worsening kidney function and changes in kidney structure.
- - Twenty piglets underwent assessments using magnetic resonance urography (MRU) and diuretic renography (DR) both before and after surgery, revealing that 12 kidneys exhibited delayed TTT post-operation, indicating significant functional and histological changes.
- - The results suggest that delayed TTT in hydronephrosis is not just a marker of reduced kidney function but also suggests alterations in kidney physiology, particularly relating to increased activity of the
Magnetic resonance imaging (MRI) presents the main diagnostic tool for differentiation and staging of renal tumors in childhood. Nephroblastoma is the most common malignant tumor in children. Radiological findings play an important role in therapy study trials of SIOP (International Society of Pediatric Oncology), especially for indicating preoperative chemotherapy.

There has been great progress in diagnostic and therapeutic management of intussusception. Ultrasound (US) has been shown to be the first-choice imaging technique in diagnosing intussusception for reasons of high accuracy, simultaneous exclusion of differential diagnoses, and disclosure of additional pathologies.

Especially the occult dysraphisms are marked by suspect skin masses and other dermal anomalies. The purpose of this review is to demonstrate the indications and spectrum of spinal sonography in neonates and infants.

Magnetic resonance imaging also permits the evaluation of renal functional processes using fast dynamic sequences. Principally, an agent cleared by renal excretion is intravenously injected and its cortical uptake, parenchymal transport, and eventually its urinary excretion are followed with serial images.

Materials And Methods: Sixty-two patients with urinary tract dilatation underwent prospective examination with combined static-dynamic MR urography. A combination examination involved use of a static T2-weighted three-dimensional inversion-recovery fast spin-echo sequence and a dynamic T1-weighted two-dimensional fast field-echo sequence with gadopentetate dimeglumine-DTPA and furosemide application.
