Thesis
There are nearly 200 national medical quality registries in Scandinavia that collect a defined set of clinical data on patients with a specific diagnosis or condition, with the aim to monitor and improve healthcare services nationwide. However, there is great variation in the quality of data recorded in the registries. Therefore, a literature revie...

Background and aims CP is a clinical diagnosis caused by a brain anomaly or injury early in life. Cerebral MRI is increasingly used in the diagnostic work-up to demonstrate the location and extension of the lesion, and may in addition provide clues to aetiology and timing. The aim of this study was to describe the distribution of different MRI patt...
