OPTIMASI KUALITAS CITRA CT SCAN SINUS PARANASAL PADA PENGGUNAAN TEKNIK LOW DOSE (LITERATURE REVIEW)
- Bagikan:
CT scan is a diagnostic modality that uses X-ray radiation. In a CT scan, it is important to pay attention to the parameters used. Parameters that produce minimal radiation dose and good image quality are exposure factor. CT scan of the paranasal sinuses at the standard of examination using an exposure factor of 120 kV, 200 mAs. While using an exposure factor of 80 kV, 30 mAs with the use of iterative reconstruction method can provide good image quality. Examination of the paranasal sinuses is very close to radiation-sensitive organs such as the eyes and thyroid gland, so minimal radiation dose is required with good image quality. To find out the efforts made in optimizing the image quality of CT scans of the paranasal sinuses using a low dose technique.
This type of research uses descriptive research with a literature review approach. The data sources of this research are articles on journal websites such as Pubmed, Research Gate and Google Scholar. used to search for relevant articles. Search journals in this study using keywords, CT scan paranasal sinuses, low dose, image quality, optimization. The selection of articles was adjusted to the inclusion criteria and obtained eight articles and then conclusions were drawn.
Efforts were made to optimize the image quality of CT scans of the paranasal sinuses using a low dose technique, and it was concluded that the exposure factor was the best in obtaining a minimal radiation dose with good image quality in the range of 80-120 KV and 40-60 mAs. By using FBP and iterative reconstruction can improve the quality of the resulting image, but the use of iterative reconstruction produces a smooth and can reveal anatomy that is not visible in the use of FBP.
