Fat suppression spectral adiabatic inversion recovery (SPAIR) to optimize the quality of MRI pelvis image

Introduction: : The ovary is a complex and heterogeneous tissue arrangement, making it easy to trigger ovarian tumors. Magnetic Resonance Imaging (MRI) is a diagnostic tool that is safe to use for ovarian tissue and can produce optimal images on soft tissue. This study aims to optimize the quality of pelvic MRI images using the Fat Suppression Spectral Adiabatic Inversion Recovery (SPAIR) technique. Methods: This research was conducted at Brain Clinic Surabaya using MRI GE 1.5 T aircraft. Data analysis used was the ROI and Histogram methods. Results: The results of the study based on the SNR, CNR, Variance, and Standard Deviation values showed that the Ovary and Colon tissue was very good in the T1 Contrast SPAIR sequence, because the tissue structure was heterogeneous, containing lots of water and fat. The Vesica Urinaria network is excellent in T1 Fat Saturation sequences. The SPAIR technique is selective against heterogeneous tissue and is able to suppress fat well using adiabatic pulses. The Vesica Urinaria network is optimal in the SPAIR technique, because the intensity and signal distribution at each pixel is very high. Conclusion: So the quality of the pelvic MRI anatomical image is influenced by the variation of the sequence in T1 Contrast.
