OBJECTIVE Using human volunteers and phantoms emulating CSF, we analyzed the effects of varying protein concentration on the signal intensity of saline solution. Also, for different fluid-attenuated inversion recovery (FLAIR) sequences, we compared protein concentration thresholds above which the signal from these solutions becomes hyperintense to that from brain parenchyma. SUBJECTS AND METHODS Nine albumin solutions of varying concentrations (3.9 mg/dl to 2500 mg/dl) were imaged using fast… CONTINUE READING
