Methods of imaging the brain Imaging the brain's structure and examining its physiology, both in the acute and elective setting, are now the domain of multiplanar, computer-assisted imaging. The imaging modalities in use today include the following: 1. Computed tomography…
Imaging modalities 1. Plain films . These are cheap, widely available and valuable screening tools in the preliminary assessment of osteoarticular symptoms. Standard views require a minimum of two views perpendicular to each other, e.g. antero-posterior and lateral projections. The…
Positron emission tomography imaging Positron emission tomography (PET) imaging is a technique used to detect and accurately stage malignant disease, to differentiate benign and malignant tissue, and to assess response to treatment. Until recently, PET imaging availability was restricted due…
