| Popis: | In this study, the authors examined the usefulness of subtraction techniques in vertebral cancer patients by comparing contrast enhanced images with before/after contrast enhancement subtraction images. In patients with metastatic vertebral cancer, contrast enhanced images and subtraction images were acquired in sagittal and axial planes. On sagittal planes, between the first and the fifth lumbar vertebrae, in three areas of metastatic vertebral cancer and in areas above and below areas with vertebral cancer, signal to noise ratios (SNRs) and contrast to noise ratios (CNRs) were measured. On axial planes, in five vertebral cancer areas, right and left vertebral arches, and right and left longest muscle areas, SNRs and CNRs were also measured. In sagittal planes, when images were divided into contrast enhanced images and subtraction images, SNRs were relatively decreased in the areas above and below vertebral cancers. On axial planes, SNRs were relatively reduced in the right and left vertebral arch and ri... |
