Colour Doppler ultrasonography replacing surgical exploration for acute scrotum: myth or reality?
Traditionally, every patient with an acute scrotum needed surgical exploration for definitive exclusion of testicular torsion. ⋯ US has proven to decrease the number of emergency scrotal explorations, length of hospital stay and hence reduce the cost of management of acute scrotum.

Review Case ReportsIntracranial involvement in extramedullary hematopoiesis: case report and review of the literature.
Intracranial involvement in extramedullary hematopoiesis (EMH) is rare, but it should be suspected in patients with myelofibrosis presenting with chronic severe headache. We present a 9-year-old girl with known myelofibrosis whose headaches were unresponsive to routine treatment. ⋯ CT examinations of the chest and abdomen had demonstrated bilateral thoracic paraspinal masses caused by EMH, suggesting the possibility that the intracranial involvement might also be related to EMH. The diagnosis was confirmed by sulfur colloid isotope scan.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialComparison of gadobenate dimeglumine (Gd-BOPTA) with gadopentetate dimeglumine (Gd-DTPA) for enhanced MR imaging of brain and spine tumours in children.
Gadobenate dimeglumine (Gd-BOPTA) demonstrates superior enhancement of brain tumours in adult patients than Gd-DTPA. ⋯ At an equivalent dose Gd-BOPTA is significantly better than Gd-DTPA for visualization of enhancing CNS tumours in paediatric patients.

Comparative StudyCT can reduce hospitalization for observation in children with suspected appendicitis.
There are no clinical or laboratory tests that can eliminate the possibility of appendicitis in a child with abdominal pain that suggests the diagnosis. The standard of care is to admit these children to the hospital for observation. More than twice as many children hospitalized for abdominal pain suggesting appendicitis are subsequently sent home after observation compared to those who undergo appendectomy. ⋯ Our data suggest that when the appendix can be visualized, CTRC can accurately identify a normal appendix and reduce the number of children hospitalized for observation for possible appendicitis.

The investigation of the acute abdomen in infants and children has evolved during the last two decades, placing imagers at the forefront of the evaluation and diagnosis of acute right lower quadrant abdominal problems. US and CT have recently been shown to be equally accurate in the diagnosis of acute appendicitis, but not everyone agrees. ⋯ We attained a high degree of diagnostic accuracy in patients presenting with findings suggestive of appendicitis using US as the primary imaging modality. Our false-positive appendectomy rate was 3%. Therefore, triage of the acute abdomen with US supported by CT when required has considerable merit, especially when considering that US is noninvasive and does not use ionizing radiation.
