In this paper we will focus especially on proton (hydrogen) MRS. Generally published literatures consist of reviews and articles about metabolites are long, complicated and emphasise on physical or on technical data. But with this article, we will try to explain basically how MRS could be used in daily practice of radiologists. First of all we tried to search all current literature only referencing the main ones to make this review and we want all of our colleagues to give feedback about this review. With collection of all these trick points and line up to appropriate order, it is possible to make this review a common guide for radiologists and a useful tool while reporting MRS.展开更多

Methods: We assessed the records of the patients who underwent paranasal sinus computed tomography imaging for suspected sinusitis. Results: We identified a total of 52 patients with a pre-diagnosis of maxillary sinusitis. Dental indentation was detected in 58 of 104 (55.7%) sinuses. Forty six of 58 sinuses (79.3%) with dental indentation had mucosal thickening higher than 2 mm. The difference between the groups was statistically significant (p = 0.007). Conclusion: Dental indentation should be kept in mind as a reason for chronic maxillary sinus inflammation, if an underlying cause cannot be identified.展开更多
