| Computed tomography (CT) is an essential tool in diagnostic imaging for evaluating many clinical conditions. In recent
years, there have been several notable advances in CT technology that already have had or are expected to have a
significant clinical impact, including extreme multidetector CT, iterative reconstruction algorithms, dual-energy CT, conebeam CT, portable CT, and phase-contrast CT. These techniques and their clinical applications are reviewed and illustrated
in this article. In addition, emerging technologies that address deficiencies in these modalities are discussed. Magnetic
Resonance Imaging (MRI) has been a potential tool in diagnostics in lesions in human body. It is accurate due to the sound
biological principle behind it. It has an array of unique features; but is not free from certain constraints which hinder the
smooth progression of its course. This article throws light on the salient features and constraints pertaining to MRI, with an
insight towards the future prospects of the sameddd |
