Lung Perfusion CT: Differentiation between Lung Cancer and Progressive Massive Fibrosis
PURPOSE: To evaluate the usefulness of perfusion CT in the differential diagnosis between progressive massive fibrosis and lung cancer. MATERIALS AND METHODS: We retrospectively analyzed the perfusion CT image of 20 lesions in 13 patients with progressive massive fibrosis. Using 16 channel …

Implementation,Validation and Application of an Automated Motion Correction Algorithm in Hepatic Perfusion CT for Image-Guided Radiotherapy
Functional imaging holds promise in guiding, evaluating and predicting efficacy of cancer treatment. Perfusion imaging provides high resolution functional information generated by applying a model to a dynamic series of contrast enhanced anatomical images. The objectives of this thesis are: 1) to …

Dynamic Cone-beam Reconstruction for Perfusion Computed Tomography
Perfusion CT (Computed Tomography) is a dynamic imaging technique whose aim is to assess the blood supply to tissue. The limited field of view of current CT detectors restricts its use to perfusion studies of a small volume. The introduction of large area detectors in CT, however, will allow …

Advanced Applications of Cardiac Computed Tomography for the Difficult-to-Image Patient
… the development of computed tomographic (CT) imaging the challenges of capturing the heart, with its perpetual, vigorous motion, and in particular the tiny detail within the coronary arteries, has driven technological progress. Today, CT is a widely used and rapidly growing modality for …

Combination therapy studies with the vascular disruptive agent combretastatin-a4-phosphate (CA4P)
… shutdown of tumour core, with minimal effects at the well perfused periphery. CA4P showed minimal anti-tumour activity in single agent phase I studies. This thesis examined the feasibility of CA4P combination therapy, examining the hypothesis that two agents may be additive or synergistic, …
