Inclusion Criteria
1) Children = 12 years of age requiring MRI of the head under procedural sedation for medical reasons
2) Written informed consent form parents/legal guardians before enrolment
Exclusion Criteria
1) Refusal to participate in the study by guardians and/or children
2) Patients with a known instability of the cervical spine
3) Patients with airway abnormalities
4) Patients with tracheostomy
5) Poor image quality of the MRI images, which would make a qualitative intertpretation impossible.
Study & Design

- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Angular range [in degrees] of head extension in defined age groups, which has the largest volumetric diameter of the air column [cm3] (=”optimal positioning”).
- Secondary Outcome Measures
Name Time Method 1) Correlation of the optimal positioning on the MRI image with the clinical assessment (thoracic excursions, work of breathing, breathing sounds) of the anesthesiologist<br>2) Correlation of optimal positioning with the capnography curve (etCO2). Since the respiratory gas flow depends on the condition of the upper airways, changes in head position that has a relevant effect on the airways are also reflected in the capnography curve (area under the CO2 curve).<br>3) Description of other measures and manoeuvres that may be required to maintain a patent airway, e.g. chin lift, Esmarch manoeuvre or devices to maintain a patent airway
