Medical Image Analysis is one of the most common and important use cases of Data Science in the Healthcare sector. Medical Image Analysis deals with creating images of various body parts that can be used for Diagnostic and Treatment purposes. Some of the Medical Imaging techniques include CT scans, Sonography, X-Ray, MRI  (Magnetic Resonance Imaging), etc.

Previously, doctors would manually analyze these images and look for anomalies. However, this method was not very reliable and often doctors were unable to suggest proper diagnosis or treatments to the patients. But, with the advancement in technology, it has become possible to examine medical images with high accuracy. Thus, Data Science in Healthcare plays an important role in inspecting the anomalies present in the Medical Images and providing accurate diagnoses and treatments.

2) Predictive Analytics
