Sarkar SN, et al. - This research was carried out in order to determine how neck tissue contrasts, image artifacts and fat separation as opposed to fat suppression in terms of image quality compared between routine and iterative Decomposition (of Water Fat signal) using Echo Asymmetry & Least-squares Estimation Fast Spin Echo (IDEAL FSE) in patients clinically indicated for neck MRI. Experts drew the conclusion that high Signal-to-Noise ratio (SNR) inherent in IDEAL FSE consistently translated into high tissue contrast with image quality advantages in neck anatomy where large susceptibility variation and physiological motions reduced the image quality for conventional FSE T1 and T2. Nevertheless, statistically equivalent objective contrast estimates for parotid gland at isocenter were brought to light for IDEAL and conventional FSE. This was possibly attributed to the fact that at or near isocenter routine FSE worked well. It was also revealed that fat-specific IDEAL image sets added to the diagnostic specificity for fat deficient lesions.
