Parotid gland tumors: preliminary data for the value of FDG PET/CT diagnostic parameters.
The purpose of this article is to establish (18)F-FDG metabolic imaging parameters to differentiate benign and malignant tumors of the parotid gland. ⋯ FDG PET/CT SUV(max), metabolic tumor volume, and total glycolytic activity are imaging parameters to differentiate benign and malignant tumors of the parotid gland.

Usefulness of dynamic contrast-enhanced MRI in differentiating between septic arthritis and transient synovitis in the hip joint.
The purpose of this study was to show the usefulness of dynamic contrast-enhanced MRI (DCE-MRI) and to determine the optimal time window in MRI for differentiating between septic arthritis and transient synovitis in painful hip joints. ⋯ DCE-MRI is useful in differentiating between septic hip arthritis and transient synovitis. If static contrast-enhanced coronal MRI is used, the optimal time for the acquisition of contrast-enhanced coronal MRI is approximately 3.5 minutes.

Chronologic change in the growth plate after radiofrequency-induced thermal injury: MRI-histologic correlation.
The purposes of this study were to assess chronologic changes in normal growth plate after radiofrequency-induced thermal injury and to evaluate the feasibility of MRI for revealing alteration of the growth plate. ⋯ Radiofrequency-induced thermal injury causes early closure of the physis. MRI can depict the extent of radiofrequency-induced thermal injury and alterations in the physis that lead to early closure.

Pediatric sedation in a community hospital-based outpatient MRI center.
Although the demand for pediatric MRI is increasing, it is uncommon to find sedation being offered at community hospital-based outpatient centers. We present our safety, efficacy, and outcome data at a community hospital-based outpatient imaging center. ⋯ Dexmedetomidine offers an option for pediatric sedation for MRI at community hospital-based outpatient settings. It preserves respiration but elicits deviations in blood pressure and heart rate that have not required pharmacologic intervention. Dexmedetomidine offers a safe, effective, and efficient agent for sedation for children undergoing MRI in an outpatient setting.
