EPIMix Versus CT Brain Pediatric Study

Study Overview
=================
Brief Summary
-----------------
This study aims to assess the diagnostic feasibility and diagnostic performance of a new fast MR sequence EPIMix for neuroradiological evaluation in comparison to computed tomography of brain in pediatric population.

Detailed Description
-----------------
The study aims to assess the feasibility of fast MR sequence for neuroradiological evaluation in comparison to computed tomography of brain in pediatric population. Imaging quality is analysed with regards to artefacts and lesion conspicuity as well as its diagnostic potential in rendering a probable diagnosis. The primary study aim is to define feasibility and the AUC for diagnostic performance of minute MRI compared to computed tomography. Included patients are children age 4-18 with suspicion of cerebral pathology with referral to elective computed tomography of the brain. Study participants are in addition to computed tomography investigated during same day at 3T MR.

| Lesion location determination | Anatomical localization of abnormality (Cerebrum, Cerebellum, Brainstem, Intraventricular, Subarachnoid space including basal cisterns, Intra-orbital, Skull/Skull base/dural, Other) | At 0 hours | 
| Diagnostic imaging quality | Diagnostic imaging quality (5 point Likert scale; 1 - Excellent diagnostic imaging quality, 2 - Good diagnostic imaging quality, 3 - Sufficient diagnostic imaging quality, 4 - Restricted diagnostic imaging quality, 5 - Poor diagnostic imaging quality) | At 0 hours | 
| Lesion description | For example effect on brain parenchyma and size | At 0 hours | 
| Diagnostic confidence | Five point Likert scale (Very confident, Predominantly confident, Fairly confident, Only slightly confident, Not at all confident) | At 0 hours | 
| Clinical diagnostic summary report | Text (one sentence summary of the finding including type of lesion and location) | At 0 hours | 
| Ability to rule out diseases | A list of diseases. Number of positive versus negative cases for each investigation (including: Tumor, Abscess, Parenchymal Haemorrhage, Acute Ischemia, Hydrocephalus, Neuroinflammation, Subarachnoid hemorrhage, Extraaxial fluid collection) | At 0 hours |
