Medical imaging or x-ray imaging has contributed a lot to bringing improvement in the diagnosis or cure of different medical conditions, be it in kids or adults.
Medical imaging procedures are of varied types for children. These procedures differ in terms of the technologies and methods they implement. Ionizing radiation is used by radiography, fluoroscopy, and Computed tomography (CT) to produce body images. As the name implies, ionizing radiation is one of the different kinds of radiation with sufficient amount of energy which may lead to DNA damage. It can even increase the risk of developing cancer in the patient.
The principle on which the three techniques mentioned above are based is the same i.e. passage of an X-ray beam through the body and absorption or scattering of a part of x-rays by the internal parts. The rest of the x-ray pattern is transferred to a detector which gets recorded or processed further via a computer.
The purposes of fluoroscopy, radiography and Computed tomography (CT) are different. Radiography focuses on a single image which is recorded or stored to be assessed later. Fluoroscopy involves display of an x-ray image continuously on a monitor so that a process or contrast agent path could be monitored in real-time. High radiation doses may be experienced by the patient in fluoroscopy.
The third exam is CT or computed tomography, which involves recording of x-ray images while the patient has the detector move around his body. Individual pictures are reconstructed by a computer into cross-sectional images of internal body parts. As compared to conventional imaging, a CT test may also involve a high dose of radiation, since numerous individual x-ray projections reconstruct the CT image.
Benefits of imaging:
X-ray imaging tests are known as one among the most vital tools that helps in different kind of medical procedures such as painless detection of any illness, interventional procedures like stents, placing catheters or some other tool inside the body, and medical treatment planning support.
An important imaging examination generally involves a small risk as compared to the numerous benefits it offers in terms of helping in diagnosis of a problem accurately.
Information for Patients
According to what FDA suggests, a person’s health needs should be very carefully examined before he undergoes any kind of a medical imaging test. A physician should suggest that this test is necessary for figuring out the patient’s exact condition. The small risk that the medical imaging test exposes the patient to is overshadowed by the benefits it offers. Doctors and researchers should still try to find out measures to minimize the small risk.
