Abstract
We first discuss historical developments in tomographic imaging used for medical diagnosis. To discuss magnetic resonance imaging, we introduce the fundamental ideas of magnetic moment, nuclear magnetic moment, and total magnetization. Then, we clarify the notions on classical precession and the principle of magnetic resonance signal detection and explain spin–lattice and spin–spin relaxation. Further, the relevant details of MRI machine and its components like magnetic gradient coils, signal generation, and pulse sequence–k-space imaging are discussed in brief form.
We then introduce computed tomography (CT) based on X-rays. Basic concept of X-ray, different generations of CT, EBCT, helical CT, etc., are introduced. Various clinical applications of CT scan image are discussed in brief. The last item discussed is positron emission tomography scan (PET scan), its basic principle, and utilities. The concluding remarks regarding these imaging techniques and comparison in medical diagnosis are made.
