ReviewPost-operative cardiac lesions after cardiac surgery in childhood.
A new population of patients in cardiology has been growing steadily so that the number of grown-ups with congenital heart disease (GUCH) is almost equal to those under paediatric care. The dramatic improvement in survival should lead to a larger number of GUCH patients than children with CHD in the new millennium. ⋯ Cardiovascular CT and MRI are often complementary in providing comprehensive complex anatomical evaluation, haemodynamic assessment of residual postoperative lesions and complications of surgery. A thorough understanding of postsurgical corrections is a prerequisite for choosing the optimal imaging techniques and achieving an accurate evaluation.

ReviewNew MR sequences (diffusion, perfusion, spectroscopy) in brain tumours.
While MRI has been instrumental in significantly improving care in children harbouring brain tumours, conventional sequences lack information regarding functional parameters including cellularity, haemodynamics and metabolism. Advanced MR imaging modalities, such as diffusion (including diffusion tensor imaging and fibre tractography), perfusion and spectroscopy have significantly improved our understanding of the physiopathology of brain tumours and have provided invaluable additional information for treatment planning and monitoring of treatment results. The contribution of these methods to the characterization of brain neoplasms in children is the focus of the present manuscript.
