Discover ways to manipulate tomography images
Simply put, tomography is an X-ray that provides a 360-degree image. Therefore, it is an exam that generates these sliced images, which can be analyzed from any angle.
The results of CT scans come out quickly, being available in most hospitals, both for emergencies and for diagnosing orthopedic injuries or investigating diseases.
Thanks to advances in technology, doctors today are able to manipulate the images obtained from tomography exams, in order to make the diagnosis more assertive.
Next, check out the main ways to manipulate these computerized images.
Multiplanar reconstruction, also known as MPR, is a technique that allows, from a single series of images, made in a well-defined orientation, to generate other series of images in other orientations.
One of the main positive points of this technique is that the images generated do not lose their quality. In other words, it is possible to visualize a certain area of the exam in several orientations simultaneously, facilitating the doctor’s work and improving the quality of the diagnosis.
MPR allows the doctor to analyze the examination in different sections (coronal, axial or sagittal), contributing to the visualization of the structures in a completely three-dimensional way.
Maximum or minimum intensity projection
These techniques are known as Mip / Minip. It consists of applying intensity attenuation to some structure, thus allowing the manipulation of tomography images.
This technique is very useful when it is necessary to highlight certain structures, such as small vessels, bronchioles or even contrast points to improve the diagnosis. In addition, this tool is widely used in chest CT scans, as it is an important support in the location of emphysema, cysts or nodules in the lungs.
With the application of the Hounsfield scale (HU unit), the doctor is able to bypass a specific region that he wants to analyze, in addition to being able to measure the radiodensity of some structure.
When the tomography is performed in a specific region of the body, the affected tissues and elements end up absorbing different levels of radiation and, therefore, it can become difficult to identify exactly what each area is. That is why the Hounsfield scale is so important for medicine.
The system itself even manages to compare the scale and point out what is in the area selected by the doctor: blood, water or some other liquid, for example.
As the name implies, several image management systems allow the use of auxiliary tools to create a three-dimensional view of the exam.
The three-dimensional visualization of the exam is very useful, for example, in the evaluation of bone injuries and fractures.
It is also widely used in the preoperative for some surgeries, because 3D allows the doctor to make a complete assessment of the structures that will undergo interventions.
Regardless of the technique, it is important to note that the use of image manipulation technologies allows for better planning of less invasive surgeries, for example.
In addition, these tools have become increasingly useful, not only in diagnostic centers, but also for professionals who work in offices.
