Multi-slice CT scan
Multi-slice CT scan Section
CT scan, or computed tomography scan (CT scan), is one of the advanced medical imaging techniques. After plain radiography, CT scans provide the most significant assistance in evaluating lesions in the human musculoskeletal system. Today, the use of CT scans has become an integral part of diagnosing and even treating many diseases.
Using CT scan images, it is possible to observe internal body tissues and examine their structure. This information can help detect potential diseases. CT scan images provide cross-sectional views of the body. Compared to simple X-ray images, CT scans offer significantly greater detail, showing the structure of bones and even many other types of tissues within the body. This technique also allows for the visualization of the interior of bones. Modern CT scan images are far more precise than before, and the speed of these devices has also improved, such that performing a CT scan typically takes only a few minutes.
Virtual bronchoscopy (Virtual Bronchoscopy)
Bronchoscopy is the direct visualization of the airways and respiratory passages of the lungs, following the nose, mouth, esophagus, pharynx, and larynx. The airways include the trachea and main bronchi. Using specialized instruments, these passages can be examined to assess various conditions such as tumors, infections, inflammation, foreign bodies, and bleeding. One of the most important reasons for performing a bronchoscopy is the early detection and timely treatment of lung cancer. Lung cancer is one of the most dangerous types of cancer, and therefore, high-risk individuals, such as smokers, should be monitored by a physician to determine if this procedure is necessary.
Common method of implementationBronchoscopyWhat is it?
Currently, in bronchoscopy centers, the procedure is performed as follows: After the patient follows preliminary steps such as fasting, they are administered either general anesthesia or a sedative, depending on the type of bronchoscopy. Subsequently, the specialist inserts a rigid tube, known as a bronchoscope (similar to an endoscope), through the nose or mouth into the larynx and the patient’s airways. The bronchoscope is advanced as far as possible to examine the airways thoroughly.
Virtual bronchoscopyWhat is it, and how is it done?
Virtual bronchoscopy is a technique in which no tube is inserted into the patient’s airways. Instead, a lung CT scan is performed, and advanced computer software is used to reconstruct and visualize the overall structure and internal surfaces of the respiratory passages, as well as lung tissue. This allows for the detection of any lesions or tumors. The procedure is very simple: the patient is instructed to hold their breath, and a lung CT scan is then conducted. No anesthesia or post-procedure care is required.

AdvantagesWhat is the difference between virtual bronchoscopy and conventional bronchoscopy?
In virtual bronchoscopy, the patient experiences minimal discomfort because nothing is inserted into the body, and there is no need for anesthesia or sedatives. Another advantage of this method is that in cases of severe airway narrowing, a bronchoscope tube cannot pass through; however, in virtual bronchoscopy, the airways can still be visualized even after narrowing. Additionally, virtual bronchoscopy has the capability to reconstruct images of lung tissue, a feature not available in conventional bronchoscopy. The time required to perform virtual bronchoscopy is also shorter compared to the traditional method.
What needs to be done to perform a virtual bronchoscopy?
Currently, virtual bronchoscopy and specialists trained in performing and interpreting it are available at this clinic. Therefore, upon the diagnosis and request of the specialist physicians for a virtual bronchoscopy, you can contact pardis noor clinic to promptly proceed with this safe and reliable procedure.

Frequently Asked Questions
What is the main difference between a CT scan and a simple X-ray?
CT scans provide cross-sectional images of the body, offering significantly greater accuracy in visualizing the structure of bones and soft tissues compared to standard X-rays. With this advanced technique, physicians can even examine the interior of bones with precision, whereas X-rays deliver a simpler image.
What advantage does virtual bronchoscopy have over the traditional (conventional) method?
The most significant advantage of virtual bronchoscopy is that it is completely non-invasive; no tubes are inserted into the patient’s airways. Unlike the conventional method, which requires general anesthesia, sedatives, and fasting, the virtual method relies solely on a CT scan of the lungs and computer reconstruction to detect lesions and tumors. This approach eliminates the need for post-procedure care or anesthesia.
Who are the primary candidates for undergoing bronchoscopy to diagnose lung cancer?
Since lung cancer is one of the most dangerous types of cancer, performing bronchoscopy on high-risk individuals, such as smokers, is crucial for early diagnosis and timely treatment. This procedure allows for the accurate evaluation of various conditions, including tumors, infections, inflammations, and even the presence of foreign objects in the airways.
Considering that the patient is exposed to radiation during virtual bronchoscopy, is this dangerous for them?
Since lung cancer is one of the most dangerous types of cancer, performing bronchoscopy is crucial for high-risk individuals, such as smokers, to enable early diagnosis and timely treatment. This procedure allows for the precise evaluation of various conditions, including tumors, infections, inflammations, and even the presence of foreign objects in the airways.
