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...

The aim of this study was to measure the bone mineral density specific regions maxilla, mandible, and first cervical vertebra using Hounsfield unit trabecular microstructure pattern analysis compare two methods. In study, cone-beam computed tomography (CBCT) images were obtained from 58 patients. Trabecular thickness, number, separation, volume fraction measured in 484 for parameters grayscale ...

Racial differences in the characteristics of urinary calculi are poorly described South African context, limiting our local understanding urolithiasis pathology and thwarting efforts designing appropriate preventative interventions. We sought to investigate among main racial groups KwaZulu-Natal, Africa. conducted a retrospective chart review patients with at quaternary hospital Africa, during ...

Computer tomographic (CT) scans are used to correct for tissue inhomogeneities in radiotherapy treatment planning. In order to guarantee a precise treatment, it is important to obtain the relationship between CT Hounsfield units and electron densities (or proton stopping powers for proton radiotherapy), which is the basic input for radiotherapy planning systems which consider tissue heterogenei...

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...

Objective: Differences in bone density before and after regenerative endodontic treatment were examined in teeth with periapical lesions in Hounsfield Units (HUs) by using Cone Beam Computed
