Several drawbacks of 2D radiography have been addressed by the use of 3D modalities such as CT/CBCT. However, these are associated with significantly increased radiation exposure. Hence, the role of MRI in routine orthodontic planning needs to be further investigated.

Objectives: The primary objective of this study was to investigate the feasibility of magnetic resonance imaging (MRI) usage over computed tomography (CT) to perform three-dimensional (3D) cephalometric analyses. The secondary objective is to find intra- and interobserver reliability of manual cephalometric landmarks identification in both CT and MRI scan data.
Methods: Data from 40 patients were used in this study, with orthodontists manually identifying 37 landmarks on both CT and MRI scans.
Background: Low dose corticosteroids (e.g., 6 mg dexamethasone) have been shown to reduce mortality for hypoxic COVID-19 patients.

Objective: 1st: To determine the association of cerebral oxygenation (rcSO) and concurrent neurodevelopmental outcomes between neonates with congenital heart disease (CHD) and healthy controls. 2nd: To examine the association of cerebral fractional tissue oxygen extraction (FTOE) with concurrent neurodevelopmental outcomes in the two groups. 3rd: To evaluate how type and severity of CHD influenced the associations in our primary and secondary objectives.

This Letter presents a search for highly ionizing magnetic monopoles in 262 μb^{-1} of ultraperipheral Pb+Pb collision data at sqrt[s_{NN}]=5.36 TeV collected by the ATLAS detector at the LHC. A new methodology that exploits the properties of clusters of hits reconstructed in the innermost silicon detector layers is introduced to study highly ionizing particles in heavy-ion data.
