Optimization of Image Quality and Radiation Dose on Lumbosacral Examination Using Computed Radiography

Introduction

Computed radiography (CR) has become a widely used imaging modality in medical diagnostics, particularly in the field of radiology. The lumbosacral examination is a common radiographic procedure used to diagnose various spinal disorders. However, the quality of the images obtained and the radiation dose received by the patient are crucial factors that need to be optimized. In this study, we aimed to evaluate the effect of tube voltage (KV) on image quality and radiation dose during lumbosacral examination using computed radiography.

Background

Computed radiography (CR) is a digital imaging modality that uses a photostimulable phosphor plate to capture images. The quality of the images obtained is dependent on various factors, including the tube voltage (KV), tube load (MAS), and the distance between the examination object and the detector. The radiation dose received by the patient is also an important consideration, as excessive radiation exposure can lead to adverse health effects.

Methodology

In this study, we measured the effect of tube voltage (KV) on image quality and radiation dose during lumbosacral examination in anteroposterior and lateral positions. The tube voltage (KV) used was 125, 80, and 65, while the tube load (MAS) was varied from 16 to 25. The dose analysis was performed using data from the tube voltage (KV) and the tube load (MAS) at a distance of 100 cm from the examination object.

Results

The results of this study showed that the application of higher techniques with tube voltage (KV) tends to reduce the value of image density compared to techniques that use standard or low tube tubes (KV). This is an important finding, considering that image quality is a key factor in medical diagnosis. The higher the tube voltage used, the radiation intensity received by the patient is also increasing.

Further analysis found that the highest contrast was produced at a variation of 65 kV with a load of 16 MAS, while the lowest contrast occurred at a voltage of 125 kV with a load of 25 MAS. This indicates that, although the use of high KV can provide images with sharper details, there are trade-offs in terms of decreased image density and potential for increasing radiation doses.

Discussion

The results of this study highlight the importance of optimizing radiographic examination techniques to minimize radiation risk while ensuring adequate image quality. The selection of parameters, such as tube voltage (KV) and tube load (MAS), is crucial in achieving this balance. The maximum radiation dose received by the patient is found in the use of 125 kV and 25 MAS, emphasizing that attention must be given to the selection of parameters to minimize radiation risk while still ensuring adequate image quality.

Conclusion

In conclusion, this study provides useful information for radiographers and other medical practitioners in improving image quality and reducing the dose of radiation received by patients during lumbosacral examination. The findings of this study underscore the need to optimize radiographic examination techniques to be in line with safe and effective radiological principles. By paying attention to the right criteria when choosing radiographic parameters, medical professionals can ensure that the results obtained are not only reliable in diagnosis but are also safe for patients.

Recommendations

Based on the findings of this study, the following recommendations are made:

Optimize radiographic examination techniques: Radiographers and other medical practitioners should pay attention to the selection of parameters, such as tube voltage (KV) and tube load (MAS), to minimize radiation risk while ensuring adequate image quality.
Use lower tube voltage (KV): The use of lower tube voltage (KV) can provide images with adequate quality while reducing the radiation dose received by the patient.
Monitor radiation dose: Medical professionals should monitor the radiation dose received by patients during radiographic examinations to ensure that it is within safe limits.
Provide education and training: Radiographers and other medical practitioners should receive education and training on the optimization of radiographic examination techniques to minimize radiation risk.

Future Directions

Future studies should focus on optimizing radiographic examination techniques for other imaging modalities, such as digital radiography (DR) and computed tomography (CT). Additionally, studies should investigate the use of artificial intelligence (AI) and machine learning (ML) algorithms to optimize radiographic examination techniques and reduce radiation dose.
