Abstract
Introduction: In many clinical situations, the radiologist wants to eliminate the contributions of fat from the total signal without affecting the water signal including in wrist joint. Frequency Selective Inversion Pulse is one of fat suppression methods where SPIR and SPAIR are among the two methods applying Frequency Selective Inversion Pulse.
Objective: This study aims to compare two fat suppression techniques SPIR and SPAIR in the magnetic resonance images of the wrist joint and to evaluate the best image quality for the clinical usefulness.
Methods: This is a quantitative research with experimental approaches conducted in Premier Bintaro Hospital. Data in form of 56 images of coronal T2WI-FSE wrist joint from 28 volunteers with two variations of the method, SPIR, and SPAIR Fat Suppression are presented. Assessment of anatomical information carried out by the radiologist and analysed with Wilcoxon Signed-Rank Test at 95 % confidence level.
Results: This research shows that there is a difference of anatomical information in MRI Wrist joint sequence coronal of T2WI-FSE between SPIR and SPAIR Fat Suppression.
Conclusion: SPAIR is the method which is clearer to show the anatomical information of wrist joint. The application of selective adiabatic inversion pulse in SPAIR makes suppression of amplitude and modulation of frequency.
