It is therefore critical that the public is made aware of the associated risks and necessary education is conducted. The voice of all radiologists, clinicians, and technicians should advocate for the safe use of CT scans for both children and adults. One issue that is crucial and needs to be addressed is CT radiation dose optimization and this should be addressed by both manufacturers and CT scanners by advocating for the balance between the benefits a patients derives from accurate CT scans against the risks involved. At all times the benefits derived should far much outweigh the risks involved when carrying out a CT scan on a patient. Consistent strategies for limiting patient radiation dose should be adopted by radiologists with the assistance of the medical physicists. On the other hand, the manufacturers should work towards improving CT technology to the level that will offer adequate diagnostic image quality and...

The recent two reported cases also suggest that there may be many more similar incidences happening around unnoticed. The two contrasting examples of overdoses of radiation at hospitals confirms that if the hospitals accept their responsibilities properly and try to serve the patient's in professional manner, such types of accidental over exposure can be avoided. Instead of creating a medical terror, the reporter managed to provide relevant information in a
Computed tomography, more commonly know as a CT or CT scan, is an X-ray technique that is used to produce very detailed images of internal organs located in various parts of the body, such as the head, chest, and abdomen. Doctors use the images produced through this procedure to help diagnose and treat diseases. Other terms for the technique are also called computerized tomography or computerized axial tomography (CAT). While
Computed Tomography (CT)Basic Fundamentals of ModalityComputer modality is the interaction between computers and humans, which can be unimodal or multi-modal (Karray et al., 2008). The fundamentals involve the usability of this interaction along with functionality. Functionality determines whether the purpose for which the interaction between humans and computer takes place is fulfilled or not. Usability is whether the adequate accomplishment of goals for which the interaction is created is effective
Conventional Tomography outlining the various aspects, issues and methods used. It has 10 sources. The field of medical imaging has been in existence for over one hundred years but new research and scientific breakthroughs have changed both its image and its role. Radiology is not only diagnostic but is expanding to encompass curative techniques as well. The most common radiological investigation remains the conventional X-ray but a wide range of
Positron Emission Tomography (PET) PET represents a new step forward in the way scientists and doctors look at the brain and how it functions. An X-ray or a CT scan shows only structural details within the brain. The PET scanner gives us a picture of the brain at work. - What is PET? The epigraph above is reflective of the enthusiasm being generated among clinicians concerning the advent of positron emission tomography
Medical Diagnostic Tools and the Effects of Nuclear Radiation on the Human Body Computed axial tomography (CAT) or computer tomography (CT) scanning technologies have been thoroughly incorporated into modern medical diagnostics. In some clinical respects, CT scans are preferable to magnetic resonance imaging (MRI) and much better than traditional X-rays. However, CT scans expose patients to more ionizing radiation and could conceivably contribute to cellular damage and to harmful cellular mutation
