Correlation between urinary tract pure stone composition and stone morphology on plain abdominal film.
BACKGROUND Crystallographic composition of urinary tract stone varies in several chemical groups and determines the degree of fragmentation to extracorporeal shock wave lithotripsy (ESWL) which has been widely used for the treatment of renal and ureteral calculi. Visual prediction of stone composition by its morphology from plain radiograph may provide a simple method and clinical hint to decid...

متن کاملNormative Vertebral Hounsfield Unit Values and Correlation with Bone Mineral Density
Background: We hypothesized that vertebral bone mineral density as measured in Hounsfield units (HU) by computed tomography (CT) can correlate with values obtained by dual x-ray absorptiometry (DXA). Our study aimed to report such a correlation along with the normative HU values within a large, heterogeneous population. Methods: We identified 2,020 trauma patients with a CT scan encompassing an...
متن کاملRelationship between Hounsfield Unit in CT Scan and Gray Scale in CBCT
Background and aims. Cone-beam computed tomography (CBCT) is an imaging system which has many advantages over computed tomography (CT). In CT scan, Hounsfield Unit (HU) is proportional to the degree of x-ray attenuation by the tissue. In CBCT, the degree of x-ray attenuation is shown by gray scale (voxel value). The aim of the present study was to investigate the relationship between gray scale...
