Multi-Slice Computed Tomography

Paper Summary:

In the last decade, computed tomography (CT) has undergone major advances and the development of multi-slice computed tomography can be considered as revolutionary because it has not only enhanced diagnostic imaging capabilities, but also ensured better patient compliance and comfort. The paper explores the numerous advantages that multi-slice computed tomography offers, the current applications of multi-slice computed tomography, future trends and also attempts to determine if there are any drawbacks to this procedure. A table and a number of photographs are included after the bibliography.

From the Paper:

"The continuous evolution of computed tomography has seen many technological improvements, and multi-slice computed tomography is one such revolutionary development. It has numerous advantages like faster acquisition speed, reduced artifacts, reduced need for contrast, high resolution images etc. Although this imaging modality has some drawbacks like increased radiation exposure, and difficulty in reviewing, reporting and archiving data, the benefits clearly outweigh the disadvantages.
"The clinical applications of multi-slice computed tomography include the ability to detect small lung nodules, visualization of cranial vessels and aneurysms, cardiac imaging and virtual colonoscopy. The future trends in development will include functional and perfusion imaging, advanced image processing and computer-aided diagnosis programs. Problems like noise and excess radiation exposure is likely to be tackled effectively."
