Diagnostic imaging: radiography or resonance? MRI or CT scan?
The use of diagnostic imaging in medical practice has seen rapid growth in the last three decades , thanks above all to the development of the technologies used and its increasingly essential integration with information technology. Precisely for this reason it is therefore a quick, simple and safe tool for defining the state of the disease X ray procedure in Rockaway.
Over the years, the increase in clinical supply has been followed by an inevitable increase in the demand for services : it is estimated, in fact, that the number of examinations provided in developed countries is increasing, with an annual growth rate of 5-11%. The request that is not always appropriate and justified is also an accomplice to this increase, which brings with it, among other consequences, an extension of the waiting lists.
In a radiology department the most performed services are:
CT (computed tomography)
MRI (nuclear magnetic resonance)
X-ray or MRI? MRI or CT scan? What are the differences? What is the best performance?
The first thing to clarify is that there is no better examination than another in general, it is a question of different methods , chosen and prescribed by the specialist doctor following an accurate assessment of clinical appropriateness. Only by following scientifically supported guidelines is it possible to define which is the most suitable test to be performed in relation to the cost / effectiveness ratio and the needs of the population .
Radiography: how are images acquired?
Radiographs are the most frequently performed examinations in Radiology, they consist in the acquisition of images through the delivery of ionizing radiation : the anatomical part subject to examination is placed between the X-ray tube (which generates and delivers X-rays) and the detection system (which receives and “reads” the rays).
Not all the rays emitted, however, reach the detector, in fact some of them pass through the body. The rays are stopped according to the thickness and type of fabric encountered, consequently what is created on the detector is nothing more than a two-dimensional map that is transformed by the computer into the classic black background image with lighter and darker areas .
