Comparative in anatomical information and artifacts between T2W TSE Cartesian sequences and T2W TSE BLADE sequences on axial cervical MRI examinations

Observation of the T2W TSE Cartesian sequence of Axial Cervical MRI Examinations still lacks a blurring on the image. One solution to overcome the blurring problem is using the BLADE trajectory. According to Finkenzeller (2014) states that TSE BLADE is significantly superior with optimum sharpness, depiction of cerebral spinal fluid, and detection of all lesions. In addition, TSE BLADE can suppress motion artifacts. The purpose of this study was to determine differences in anatomic information and artifacts between the T2W TSE Cartesian and BLADE on axial MRI cervical examination and which sequences were more optimal in terms of anatomic information and artifacts. This type of research is a quantitative study with an experimental approach involving 10 volunteers and 2 respondents specializing in radiology. Each voluntary MRI cervical examination was performed using axes T2W TSE Cartesian and BLADE sequences. Image results were examined by respondents to obtain anatomical information and artifact. The data were processed and analyzed using Cohen's Kappa test and Wilcoxon test. The results showed that there were differences in anatomic information and artifacts between the T2W TSE Cartesian and BLADE on axial MRI cervical examinations with p-values of 0.038 or p <0.05 for differences in anatomic information, and p-values of 0.024 or p <0.05 for differences in artifacts. Sequence test results indicate that the TSE BLADE is more optimal than the TSE Cartesian, using the TSE BLADE sequence can suppress blurring artifacts so as to improve anatomical information. Conlusion: There is a difference in anatomical and artifact information between T2W TSE Cartesian and T2W TSE BLADE on Axial Cervical MRI examination. T2W TSE BLADE is superior compared to T2W TSE Cartesian (paper)
