Evaluating and managing adrenal incidentalomas REVIEW ■
Adrenal masses that are found incidentally should be evaluated with both imaging and hormonal studies. The attenuation coefficient on noncontrast computed tomography (CT), expressed in Hounsfield units (HU), is better than tumor size in differentiating adrenal adenomas and hyperplastic lesions from nonadenomas. All patients should undergo hormonal evaluation for Cushing syndrome and pheochromoc...
متن کاملComparison of Tissue Density in Hounsfield Units in Computed Tomography and Cone Beam Computed Tomography
OBJECTIVES Bone quality and quantity assessment is one of the most important steps in implant treatment planning. Different methods such as computed tomography (CT) and recently suggested cone beam computed tomography (CBCT) with lower radiation dose and less time and cost are used for bone density assessment. This in vitro study aimed to compare the tissue density values in Hounsfield units (H...

متن کاملClinical utility of computed tomography Hounsfield characterization for percutaneous nephrolithotomy: a cross-sectional study
BACKGROUND Computed Tomography (CT) is considered the gold-standard for the pre-operative evaluation of urolithiasis. However, no Hounsfield (HU) variable capable of differentiating stone types has been clearly identified. The aim of this study is to assess the predictive value of HU parameters on CT for determining stone composition and outcomes in percutaneous nephrolithotomy (PCNL). METHOD...
متن کاملDifferentiation between adrenal adenomas and nonadenomas using dynamic contrast-enhanced computed tomography
This study was performed to evaluate the findings including the time density curve (TD curve), the relative percentage of enhancement washout (Washr) and the absolute percentage of enhancement washout (Washa) at dynamic contrast-enhanced computed tomography (DCE-CT) in 70 patients with 79 adrenal masses (including 44 adenomas and 35 nonadenomas) confirmed histopathologically and/or clinically. ...
