Abstract

Background: Lumbar MRI examination at T2 weighted is recommended using the Fast Spin Echo (FSE) sequence because it can detect early symptoms of a pathology, such as edema, tumors, infections, fractures, ligament injuries, and produce images with strong signals in CSF including details of nerve roots. Based on the observations of researchers at MRCCC Siloam Hospital Semanggi Jakarta that uses TR values ​​in the range of 3500-7500 ms with 3 Tesla MRI. This study aims to determine the differences in image quality and anatomical information as well as knowing the TR values ​​that produce best quality and anatomical information on Lumbar MRI on T2WI FSE. Methods: This type of research is an experiment, then a different friedman test was carried out to determine differences in image quality and anatomical information with variations in TR values ​​that produced best image quality and anatomical information. Result: Friedman test shows there are significant differences between the variation of TR on anatomical information produced with p-value < 0.001. The friedman test results obtained p-value SNR < 0.001, CNR < 0.001 and scan time < 0.001. TR which produces best image quality and anatomical information is TR 5500ms with mean rank 2.32 on Lumbar MRI examination by T2WI FSE sequence sagital slices.

Abstract

This study aims to evaluate the efficiency of use by radiographers and image quality in the use of dental holders that have been modified with silicone rubber in dental radiography procedures. Motivated by the problem in the use of conventional dental holders that often cause discomfort for patients and the potential for motion artifacts, a modification with silicone rubber was proposed. The study sample involved 16 repetitions on each head cadaver using both the innovative and control dental holders. The results of the paired t-test showed a significant difference in efficiency of use by radiographers and image quality between the two groups. The efficiency of use by radiographers increased, supported by a Cohen's d value of 9.632. The modification with silicone rubber showed better images, with a Cohen's d value of 0.325, attributed to the adjustable conus guide capability according to the size of the patient's mouth and jaw as well as the increased comfort with the silicone rubber material. This study recommends the adoption of the modified dental holder to improve procedure efficiency and quality of dental radiography results.
