Abstract

Bakcground: The differences in fat suppression MR images between Proton Density Fat Saturated sequence with STIR sequence in MRI pedis sagital view. This research aims to analyze the differences of SNR, CNR, and the details MR images. Methods: Secondary data were using by non-probability sampling technique with 10 purposive sampling of pedis MR images Proton Density Fat Saturated sequence and STIR sequence sagittal view in DICOM were done by using imageJ software. The instrument of this research consisted of a worksheet and questionnaire. Result: This research showed SNR p value/sig 0,000 < 0,05 and CNR p value/sig 0,575 > 0,05. In Proton Density Fat Saturated sequence sagittal view the detail of ekstra-articular fluids value is 1,76, tendon Achilles value is 2,88, joint space value is 2,86 and bone marrow value is 2,04, contrast resolution value is 2,418, noise ratio value is 2,32. Pedis MR images of STIR sequence sagittal view the details of ekstra-articular fluids value is 2,92, tendon Achilles value is 3,28, joint space value is 2,84 and bone marrow value is 3,4, contrast resolution value is 3,022 and noise ratio value is 2,44. Conclusion: There is a significant difference of SNR value, no significant differences in CNR value and value of MRI pedis sequence Proton Density Fat Saturated sagittal detail is clear enough to show tendon achiles, bone marrow, joint space and not clear to show ekstra-articular fluids. STIR nice to show tendon achiles and bone marrow and clear enough to show ekstra-articular fluids and joint space.
ANALISIS INFORMASI CITRA MRI GENU POTONGAN AXIAL ANTARA SEQUENCE SHORT TAU INVERSION RECOVERY (STIR) DAN SEQUENCE T2-SPECTRAL ATTENUATION INVERSION RECOVERY (T2-SPAIR) Ramandasari, Suci; Gunawati, Shinta; Winarno, Guntur; Edy W, Mahfud; Heriyanto, Fransiscus

Abstract

Background : This research aims to analyze the information of genu axial section image quality using T2 STIR and SPAIR sequences at Mayapada Hospital. Methods : The design of this research is quantitative analytics with experimental approaches conducted at the Mayapada Hospital Radiology Installation with the study population taken from all MRI genu examination patients during September-December 2020 with a study sample of 5 patients aged 18-40 years with various complaints on Genu. Then, reconstruction is carried out with a stunt cut techniques on STIR and SPAIR sequence. Result : The result of this study showed a difference in T2 STIR d an T2 SPAIR with p value of 0.025 < 0.05. Conclusion : The contrast of MRI genu sequence STIR is brighter than SPAIR sequence as evidenced by the calculation of CNR value of STIR sequence 8,388 higher than SPAIR sequence value of 5,345. So it can be concluded that in MRI genu examination, the CNR value on the STIR sequence of a stunt pieces with SPAIR sequence of a stunt pieces has a significant difference.

Abstract

Background : This study aims to determine the differences in the quality of anatomical image information and to determine the best reconstruction variation of the Mastoid CT scan. Methods : The design of this study was quantitative and qualitative analysis, conducted in the radiology unit of Banten Hospital with the study population was all patients who underwent a head CT scan. The sample was taken using a purposive sampling technique specifically for the Mastoid CT Scan examination with clinical mastoiditis. Image reconstruction was performed with three variations of the filter, namely bone standard, bone smooth, and bone sharp for analysis. Result : The results obtained were that there were no significant differences in the SNR values of the three filter variations, but there were differences in the CNR values of the three filter variations. Conclusion : Based on the study conducted, it can be concluded that data obtained qualitatively according to clinical and the results of interviews with ENT specialists and radiologists that the bone sharp filter gets the highest rate which is used to analyze Mastoid CT images, and it is recommended to assess mastoid CT images with clinical mastoiditis.
