Progress always leads to constant technological evolution, and there have been major advances in the field of Radiology as well. The most important of which has been the introduction of digitization of diagnostic processes.
Digital radiology is thus a big improvement over the analog mode, in which data are learned, stored and processed post acquisition by means of software and related hardware archives.
When compared with traditional radiography, the digital mode loses in spatial resolution, since the analog dot (the smallest element) is 2 µm in diameter (the silver bromide used in radiographic film), while the digital dot, or pixel, is a hugely larger square of space, which can range from 30 µm to 200 µm.
This variation results in a significant loss of information related to spatiality, however much the potential of the human eye is usually unable to notice such a difference under conditions of regular observation.
On the other hand, digital techniques have the faculty of a wide dynamic range, and their characteristic curve is nearly linear; possible exposure errors, which oftentimes can occur in radiology, equally bring as a dowry a useful image for diagnostic purposes. This makes us understand how, compared with conventional systems, an error in exposure will mean forcing the patient to repeat the examination, resulting in twice the exposure for the person being examined.
So as much as Digital Radiology is extremely convenient in particular conditions of research, monitoring and evaluation of overt pathologies, it is unsuitable in the evaluation of some affections of the human body, specifically for the research of problems that may affect the breast. Where mammography, on the other hand, fully makes up for this lack of resolution potential.
When Digital Radiology is ineffective, it can be replaced by Computed Tomography and Magnetic Resonance Imaging, sisters of Diagnostic Imaging.
No preparation
It is necessary to always submit the medical claim even if specialist, regardless of the type of service, contracted or private.
Bring previous instrumental and laboratory investigations and report current therapies.
The investigation can be performed within the first 10 days after the beginning of the menstrual cycle. After 10 days, the test can be performed ONLY if there has been abstention from intercourse or if intercourse has been protected. In the case of unprotected intercourse, wait for the next menstrual cycle before scheduling the appointment, or perform the beta HCG test and report to the Institute with the results (the test should be performed only if at least 15 days have passed since unprotected intercourse).
GENERIC, FOR INTESTINAL PROBLEMS OR FOREIGN BODY SEARCH:
There is no need for fasting or enema, which will be recommended if necessary depending on the clinical picture.
SPECIFICALLY FOR KIDNEY STONE RESEARCH:
Not during colic: Observe liquid diet the day before exam 6-8 hours before exam observe fasting perform cleansing enema 2/3 hours before appointment
In the course of colic: No preparation.
It is necessary to always submit the medical claim even if specialist, regardless of the type of service, contracted or private.
Bring previous instrumental and laboratory investigations and report current therapies.
RX examinations can be performed ONLY within the first 10 days after the beginning of the menstrual cycle. After 10 days, the exam can be performed ONLY if there has been abstention from intercourse or if intercourse has been protected. In the case of unprotected intercourse, wait for the next menstrual cycle before scheduling the appointment, or perform the beta HCG test and report to the Institute with the results (the test should be performed only if at least 15 days have passed since unprotected intercourse).
It should be noted that the test cannot be performed in case of certain or presumed pregnancy.
