Recent developments in techniques for respiratory motion correction in PET-CT imaging

The advent of hybrid imaging in the form of PET CT has revolutionised the practice of respiratory medicine. Due to the high sensitivity and specificity of this technique, it is possible to detect pulmonary pathologies in early stages with high degrees of certitude thereby facilitating prompt diagnosis and treatment. However, the presence of respiratory motion artefacts depreciates the diagnostic accuracy of this technique. Multiple motion correction techniques have been developed to overcome this predicament. In this paper, these techniques have been reviewed from existing scientific literature. DOI: http://dx.doi.org/10.3329/bjnm.v17i1.22496 Bangladesh J. Nuclear Med. 17(1): 84-90, January 2014
