Disease occurrence rates in humans are rapidly rising for various reasons and so timely detection and treatment implementation are necessary to ensure successful cures. The disease diagnosis procedure varies based on the type and severity of the disease. Further, this scheme also depends on the infected area under examination. In most cases, verification by a doctor, followed by signal-based prescreening and image-based postscreening is widely recommended to confirm the disease and its severity. This chapter provides a detailed overview of image-supported disease screening procedures adopted in hospitals to examine the various internal organs, such as the breasts, heart, and brain. The various imaging modalities considered to examine the abnormalities in these organs are examined and the advantages and disadvantages of the considered imaging schemes are discussed. Compared to other imaging methods, magnetic resonance imaging is confirmed as one of the most widely adopted radiological procedures to identify disease in these organs with improved visibility.
