The Hounsfield units into density conversion for a commercial treatment planning system (TPS) is discussed. The impact of an average calibration table provided by the manufacturer on computed doses was investigated when a customer calibration could not be included in the TPS. The maximum error determined on the computed monitor units per Gy was found to be about 2%, being below 1% on average. T...

The variability assessment of the rib bone mechanical properties during the growth process is still missing. These properties could not be obtained in vivo on children. Relationships have been obtained between Hounsfield Units from computed tomography (CT) and mechanical properties (e.g. for the cortical bone on adults). As a first step for investigation of the mechanical propertie...

Introduction: Cone-beam CT (CBCT) is an imaging system which offers three-dimensional (3D), multiplanar images and has many advantages over computed tomography (CT) including shorter acquisition times for the resolution desired in dentistry, lower radiation dose to the patient, reasonable price and higher spatial resolution but CBCT scanners are unable to display actual Hounsf...

Muscle atrophy has been demonstrated in patients suffering from osteoarthritis of the hip, but little is known about muscular recovery after total hip replacement (THR). A total of 20 patients with unilateral osteoarthritis of the hip were assessed before, six months and two years after THR. The cross-sectional area and radiological density of the muscles of the hip, thigh, calf and back were m...

This study compared sensitivity and specificity of multidetector-row computed tomography and duplex Doppler ultrasonography in detecting atherosclerotic carotid plaques complicated with intraplaque hemorrhage. Carotid plaques from 50 patients operated for carotid artery stenosis were analyzed. Carotid endarterectomy was performed within one week of diagnostic evaluation. Results of multidetecto...

Dual energy CT is a recent upgrade to this diagnostic imaging technique. The purpose of critical narrative review lay out the clinical applications Hounsfield Units and their variation across x-ray spectrum using DECT. We explore new reconstruction methods parametric maps helpful for diagnosis prevalent pathologies such as fatty liver disease, urolithiasis, identify complications after interven...
