In recent years, with the development and advancement of medical technology, CT scanning has become one of the important tools for tumor diagnosis. However, despite the fact that CT film is one of the most common forms of diagnostic images, more and more physicians are turning to the use of digital images and avoiding the use of CT film.
So why don't doctors look at CT films anymore?
Starting from the characteristics of CT film, we can see some problems. First of all, CT film is a printed paper medium to display images, which limits how the images can be presented. Compared to digitized images, CT film has a relatively small number of layers.
Under normal circumstances, a CT scan can obtain data on hundreds of layers, but only a dozen or twenty layers can be displayed on film. This prevents doctors from getting a more complete picture when looking at the nodules. In addition, the film image is very small and cannot be enlarged. This makes it very difficult for doctors to look for small nodules and accurately determine their specific morphology, density, and CT values.
Secondly, there are some technical problems with the use of CT film for diagnosis. Since CT film is viewed through optical magnification, this makes the image susceptible to light interference.
In addition, doctors have very high requirements for the quality of film images, and any bit of noise or blur can have an impact on an accurate diagnosis.
In addition, some patients may take a picture of the CT film with their mobile phone and upload it to the doctor for diagnosis.
However, this often results in the image being flipped or inverted, making it impossible for doctors to accurately determine the location and shape of the nodule. In response to the above problems, the emergence of digital images provides doctors with better diagnostic tools.
First, digitized images are more informative. With digital technology, doctors can see more layers of the image, and they can zoom in or out as needed. This allows the doctor to more accurately assess the nature and characteristics of the nodule and make a more accurate diagnosis.
Secondly, the convenience of digital images also brings advantages to doctors. With electronic images, physicians can conduct remote diagnoses and case discussions anytime, anywhere, rather than being limited to the transmission of physical film. This not only saves time, but also promotes the efficient allocation and application of medical resources.
With the support of digital images, doctors can get a more complete view of the nodules by adjusting image parameters, applying blurring, and more. This method makes up for the shortcomings of the CT film form to a certain extent.
In summary, CT film, as a form of tumor diagnostic image, due to its limitations and technical problems, more and more doctors no longer view CT film directly, but turn to the use of digital images. Digital images not only provide richer information and more convenient operation, but also improve doctors' accurate judgment of the nature of tumors, providing more effective support for patients' diagnosis and **.
