Clearer Image of Computed Tomography by Reconstruction Analysis Method

Computed tomography (CT) has been widely used for long. In recently years, the useful application of CT would be the method of the reconstruction images. Historically speaking, reconstruction images were conducted so far by algebraic reconstruction technique (ART), filtered back projection (FBP), iterative reconstruction (IR) algorithms and so on. There are various effects of reconstruction image of CT in clinical practice. Two cases with such beneficial experiences were reported. Case 1 is 74-year-man with hypertension. He was diagnosed to have abdominal aortic aneurysm (AAA). By reconstruction images, the general shape and details were clearly observed including regulating background data. Case 2 is 48-year-female without history of low back pain. When she received abdominal CT, she was pointed out to have lumbar disc herniation between L4 and L5. The diagnosis was done from the lateral tomography of lumbar vertebrae. By reconstruction images with colored modification, the detail status of herniation was clearly observed. Consequently, reconstruction image method of CT would be useful and effective. Further evolution of CT apparatus and development of computer analysis would be expected for better clinical practice and research in the future.
