The impact of nonstandard hip rotation on densitometric results of hip regions and potential misclassification of diagnosis.

Unlabelled: The present study is intended to investigate the degree to which insufficient internal rotation could impact the densitometric results and change the diagnosis. A significant difference was found between the results in nonstandard compared with standard rotation and an increase in the BMD and T- and Z-scores from nonstandard to standard rotation. Likewise, a change in diagnosis was observed in a significant proportion of patients.

Rapid Decomposition of 99mTc-MAA Complex During Lung Perfusion Imaging.

A 30-year-old woman with a recent episode of dyspnea was presented. The lung perfusion scan using Tc-MAA (macro-aggregated albumin) initially revealed an acceptable lung-to-background activity ratio implying a proper radiopharmaceutical preparation and radiolabeling efficiency. Unexpectedly, later during the scan, rapidly increasing concentration of activity was observed in salivary glands, thyroid and stomach.

Shifting paradigms in the management of pediatric differentiated thyroid cancer from static to dynamic risk stratification: a step forward toward precision medicine.

Introduction: This study aimed to assess the usefulness of a risk-adopted management system known as dynamic risk stratification (DRS) in comparison with the American (ATA) and European Thyroid Associations' (ETA) risk classifications in the management of pediatric patients with differentiated thyroid cancer (DTC).

Materials And Methods: The current study included 50 pediatric patients with DTC who were treated with total or near total thyroidectomy and radioiodine ablation whose risk assessment was initially defined according to the ATA and ETA guidelines. During the two years after initial treatment, patients were reclassified according to their DRS.
