Important Principles of radiographic Interpretation
- An essential first step is to ensure that there are an adequate number of images of diagnostic quality that display the region of interest in its entirety.
- When using plain or projection images, multiple images at slightly different projection angles and images exposed at right angles to one another often provide significant additional information.
- When appropriate, the use of advanced forms of diagnostic imaging can also provide valuable diagnostic information.
- Recent research has shown that the employment of a systematic search strategy by novice clinicians improves their ability to detect abnormalities in panoramic images. A systematic search strategy involves the identification of a list of normal anatomic structures that would be contained within the image.
- Understanding the basic disease mechanism underlying the changes that each type of abnormality can render in the diagnostic image is more effective in enhancing a clinician’s diagnostic accuracy.
- The non-analytic strategy: assumes that simply viewing an abnormal finding automatically leads to a holistic diagnostic hypothesis, which is followed by a deliberate search for features that support the initial hypothesis.
- The analytic or systematic strategy: a step-by-step analysis of all the imaging features of an abnormal finding so that a diagnosis can be made based on these findings.
