Magnetic Resonance Imaging (MRI) was developed on the principle of Nuclear Magnetic Resonance (NMR), first observed in 1938 by Rabi [1] and subsequently formulated in 1946 by Bloch [2] and Purcell [3]. During the next two decades, NMR remained primarily a spectroscopy tool due to limited imaging technology, computing power, and clinical awareness. Its medical potential was not realized until 1971, when Damadian first noted that NMR relaxation times differed in cancerous and normal tissue [4]. La…
