Here is the Latest Technology Multislice Tomography
(Update: ) - general subjects
Multislice Tomography (MS-CT) new generation advanced and multi-section computed tomography. It is the technology that scans the human body in very thin sections (sections smaller than 1mm) within seconds.
So what are the benefits of having too many thin sections?
Think of it this wayLet's compare the human body to a watermelon, each organ being a watermelon slice, and diseases in the seeds inside the watermelon slice. If you cut the watermelon slice thick, we may not see the seeds (disease, pathology) hidden in the slice. When very thin sections are made, it is possible not only to detect the presence of the beans, but also to obtain very important information about their content, location and size.
By means of Multislice Computed Tomography (MS-CT) scans made using the latest technology, the organs in the human body are literally transferred to the virtual environment in a three-dimensional (axial, coronal, sagittal) way.Virtual Anatomical examination"Is called. For example Virtual angiography, Virtual colonoscopy, virtual endoscopyvirtual cystoscopy, virtual bronchoscopy etc.
Multislice Tomography (MS-BT) Usage Areas
Virtual Pulmonary Angiography
Pulmonary vessels can be examined with Multislice Tomography pulmonary (embolism, aneurysm, AVM, tumor formation)
Virtual Thoracic Tomography
With Multislice Tomography (VCT 64 Detector), lungs can be examined non-invasively with high image quality. Virtual bronchoscopy can be done. Bronchial and pulmonary vascular diseases can be demonstrated with high resolution.
Virtual Carotid Angio
With the introduction of Multislice Tomography into clinical use, it has taken its place as the gold standard in carotid vertebral system angiography.
Abdominal, Renal and Peripheral Virtual Angio (angio tomography)
With Multislice Tomography (VCT 64 Detector), atherostlerotic plaques in the vessels, previously placed grafts and stents, emboli that cause acute obstruction can be visualized non-invasively in a very short time and with high resolution.
Virtual Cerebral Angiography
It can dynamically evaluate the functional state of the brain and its anatomic. Blood volume, blood flow and transit velocity in the brain can be calculated. In addition, non-invasive angiographic imaging of the brain and neck vessels with VCT is possible.
Since early diagnosis can be life-saving, traditional colonoscopy is used for screening in high-risk patients. However, many patients avoid this procedure. Sedation is required during the procedure. Virtual colonoscopy has become an alternative diagnostic method for this patient group. With Multislice Tomography (VCT 64 Detector), the large intestine can evaluate not only the inner surface but also the outer surface.
LOMBAR DISC AND SPINE IMAGING
More precise results can be obtained by creating three-dimensional and sagittal coronal and axial images in disc herniation imaging. Especially in patients with metallic orthopedic material such as prosthesis, the deterioration in image quality observed in previous CT examinations is completely corrected with 64 vct.
What is FDG uptake?
FDG is a type of sugar. FDG stands for "2-deoxy-2- [fluorine-18] fluoro-D-glucose". Fdg uptake or FDG accumulation; It is one of the metabolic criteria used in evaluating the response to treatment in cancer patients.
F-18-FDG, a type of sugar administered intravenously, and PET technology, which displays the metabolic functions in the human body, plays an important role in the diagnosis and follow-up of various brain and heart diseases, especially cancer.
Fdg uptake means tissue that uses glucose more than other tissues. Although Fdg uptake in the lesion depends on many factors, there is a strong relationship between the FDG uptake of the lesion and the number of cancer cells:
- Decreased Fdg uptake, decreased number of viable tumor cells,
- Increased Fdg uptake is associated with an increase in the number of viable tumor cells and tumor progression.
Examples of FDG uptake
Positron emitting radionuclides are biogenic elements and they can bind relatively easily to organic molecules compared to conventional radioisotopes. In the literature, more than 500 radiopharmaceuticals that can participate in different biochemical and metabolic pathways for PET imaging have been described.
Despite this diversity, fluoro-18-deoxy-Dglucose (FDG) labeled with Fluoro-2-deoxy-Dglucose (FDG) is currently the only PET radiopharmaceutical used in clinical imaging due to its ease of manufacture and commercial distribution, and its high clinical efficiency.
FDG is licensed for human use in almost all countries and is allowed to be produced and distributed commercially. F-18 has a relatively long half-life (2 hours) compared to other PET radionuclides and therefore environmental PET imaging within a few hours from regional production (cyclotron) centers The fact that it can be distributed to centers is an important factor that makes the use of FDG widespread.
In addition, the development of computer-controlled fully automatic FDG synthesis units integrated into the cyclotron facilitates the production of FDG compared to other PET radiopharmaceuticals. Thus, it has become possible to perform PET imaging without cyclotron investment and operating costs.
Moreover, the fact that FDG can effectively monitor tumor extent by revealing increased glucose metabolism, which is a common indicator of malignant tumors, is the most important factor that makes its clinical use widespread.
