As medical imaging is continuously evolving the researchers are finding ways to enhance diagnosis and treatment planning.

FREMONT, CA: The body's internal organs and bones are concealed behind skin and other tissue barriers and are not visible to the naked eye. The word "medical imaging" refers to technology that enables doctors to see inside the human body. Today medical imaging is extremely important for patient management.

What is Diagnostic Medical Imaging?

The method of determining a particular disorder or illness based on a detailed evaluation of the patient is known as a diagnosis. Unfortunately, many diseases and conditions affect parts of the body that aren't noticeable to the naked eye.

Diagnostic medical imaging can help diagnose by assisting the physicians in seeing any potential anomalies within the body. Medical imaging, for example, may reveal if a patient's bones have been fractured or dislocated after an injury.

How does Medical Imaging work?

The use of 'invisible' waves like electromagnetic radiation, magnetic fields, or sound waves is used in diagnostic medical imaging. Understanding the various forms of waves will help to understand better about medical imaging research.

The waves are produced by a source placed on one side of the body, migrate through the body (through the area of interest), and reach a detector on the body's opposite side. Various body tissues consume the waves to varying degrees. As a result, the detector creates an image made up of 'shadows' of different body tissues.

What is Medical Imaging used for?

Spot diagnosis: 

As the name implies, it is the most popular application of diagnostic medical imaging. An image will tell the doctors exactly what is wrong with a patient immediately. Fractures, cysts, cancers, and abnormalities of the bone can all be detected with plain radiographs and CT scans.

Monitoring disease progression: 

The use of diagnostic medical imaging to evaluate the stage and progress of a disease is common. A contrast-enhanced CT or MRI can be used to establish the exact location of the disease in a patient with cancer, while PET scans can identify any metastases. A type of bone scan called SPECT has been proven to help monitor Parkinson's disease progression.

Treatment planning: 

Medical imaging can also help with treatment planning by enabling surgeons to estimate the size of a lesion and the scope of surgery ahead of time. Surgeons may use medical imaging technology to perform virtual surgery either directly in the software or after importing and constructing stereolithographic models.
