A Cone Beam Computed Tomography (CBCT) scan is a new form of advanced imagery that is quickly becoming essential to various fields, from dentistry to medical imaging. This article will discuss what a CBCT scan is and why it is used, as well as the specifics of the process and the analysis of the results.
What is a CBCT scan?
A CBCT scan is a three-dimensional X-ray technology, similar to a traditional CT scan. CBCT imaging differs from a conventional CT scan because the beam of radiation travels in a cone shape, rather than a fan shape, which means that it can be used at a lower radiation dose. It also results in a quicker image acquisition process. CBCT technology is often used when doctors need to get a more detailed picture of a particular area of the body, such as the lower jaw or skull.
Why is a CBCT scan necessary?
A CBCT scan is necessary in certain cases if a more detailed image of a patient’s bones, teeth, or tissues is required. Common uses for a CBCT scan include evaluating oral surgery, diagnosing issues in the lower jaw and sinuses, and determining the best course of treatment for orthodontics.
CBCT scans offer many benefits over traditional 2D X-rays and CT scans, such as a higher image resolution, a lower radiation dose, as well as the ability to download the DICOM (Digital Imaging and Communications in Medicine) files directly to a computer for analysis.
How is a CBCT scan performed?
Before a CBCT scan, a healthcare professional will bring a patient to a room with the CBCT scanner in it and explain the process, as well as any necessary preparatory information, such as a consent form to sign. Prior to the scan, the patient should remove any loose fittings and wear comfortable clothing. A radiopaque marker is usually attached to the area that will be scanned to help the radiologist locate and interpret the resulting image. In some cases, a contrast agent may be ingested, injected, or inhaled in order to highlight certain body parts before the scan is performed.
During the scan, the patient is placed in the correct position and asked to remain still, while the scanner is rotated around them. The entire imaging process takes between 15-30 seconds and it can be used on both adult and pediatric patients. The radiologist is in charge of the entire process, ensuring that the radiation dose used is as low as possible, while still producing a clear image.
Analysis of the CBCT results
After the CBCT scan is complete, the images are processed and ready for the radiologist to interpret. The radiologist compares the images to previous ones, as well as the visual and written information provided by the referring physician. The radiologist may also use image processing software to produce a 2D or 3D image of the data for a clearer view of the patient’s anatomical structures.
The radiologist can then determine if there are any issues, such as loose fittings, fractures, infections, or tumors. Once the scan is finished and analyzed, the images and findings can be stored and shared digitally, with the referring physician and other healthcare providers, in order to build a comprehensive treatment plan for the patient.
In conclusion
A CBCT scan is both a necessary and effective way of obtaining detailed anatomical images of a patient’s skull and mouth. It is becoming increasingly essential to various different fields and is an essential tool for diagnosing and treating a variety of conditions. The process is simple, with a lower dose of radiation than traditional CT scans, and the results can be analyzed quickly and effectively for a comprehensive treatment plan.
