Modern medicine has seen medical imaging go through multiple
advancements. The information related to human body really helps in
diverse clinical applications. Numerous kinds of medical imaging
techniques have broken the surface over all these years, with each of
these having their own special features and some disadvantages too.
There are varied methods based on x-ray that fulfill the purpose of conducting medical imaging, which may include conventional or plain x-ray, mammography and computed tomography (CT). Sometimes, contrast agents are brought into use to bring enhancement in x-ray images such as in angiography examinations.
Nuclear medicine utilizes molecular imaging, which includes usage of varied techniques to envisage biological processes that occur in different organisms' cells. Radiopharmaceuticals i.e. little radioactive marker amounts are brought into use for carrying out molecular imaging.
This, however, is not the limit. Some other kinds of medical imaging may comprise ultrasound imaging and magnetic resonance imaging (MRI). MRI and ultrasound differ from the previous kinds of imaging methods, since they work without ionizing radiation.
While strong magnetic fields are used in MRI and no irreversible biological effects are seen in the patient, high-frequency sound waves are used in ultrasound and images of soft tissues as well as internal parts of the body are obtained.

These diseases may be detected even before a CT or MR image could display them. In case molecular imaging was not there, these diseases would need a biopsy or surgery to be detected at an early stage. A biopsy indicates tissue removal so that the test could be conducted under the microscope. Brain or bone disorders along with heart and kidney ailments, gastrointestinal disorders, lung disorder and cancer are often diagnosed using molecular imaging.
