Abstract
Medical imaging techniques are a helpful tool for physicians to diagnose and treat diseases. Some of these techniques are conventional and include X-rays, Ultrasounds while others are advanced imaging modalities such as MRI and CT scans. Recently, more and more physicians are relying on these advanced imaging modalities because of advancements in technology, increased patient demand, greater finances, and the fear of any malpractice suits in case of missed diagnosis. While these techniques, no doubt, offer a quicker and correct diagnosis owing to their sharp resolution and sensitivity, they do expose the patient to a great source of radiation, are expensive, time consuming, and are not an ideal means to be used in all situations. Thus, it is crucial to mitigate their unnecessary use. The following article focuses on the growing use of such techniques, their advantages and disadvantages and how to alleviate their exaggerated use.
