There are many imaging methods which can be used to assess the structure of the brain. As part of Macquarie MindScan, the main modalities in which structural imaging is conducted are magnetic resonance imaging and computed tomography.
Magnetic resonance imaging is the technique of choice for structural assessments as it offers superior image resolution, with no ionising radiation. However, MRI is not appropriate for all individuals. Contraindications to MRI include presence of metal implants and medical devices (e.g. pacemakers, cochlear implants, neurostimulator, and aneurysm clips), as well as severe claustrophobia. In a clinical setting, CT can be utilised to assess the structural integrity of the brain when MRI is contraindicated.
Details of structural MRI sequences are provided.
