The current study was performed to assess the diagnostic accuracy of ultrasound compared to CT scan as a gold standard in the diagnosis of craniosynostosis. 44 infants (17 girls) under 1 year old, clinically suspected to have craniosynostosis, were first sonographically examined by a pediatric radiologist and were later referred to another blinded pediatric radiologist to examine CT scan with 3...

errors and variations in interpretation can happen in clinical imaging. few studies have examined the biased effect of clinical information on reporting of brain ct scans. in a blinded double crossover design, we studied whether three radiologists were biased by clinical information when making ct scan diagnosis of the brain. three consultant radiologists in three rounds with at least a one-mon...

    Background: The aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3D reconstructive CT scan imaging. Methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. Preoperatively, all the patients underwent a CT scan according to a standard ...

trauma is the most common reason in 1-34 years olds. in patient with multiple traumas, the head is the most common involved part. the importance of computed tomography (ct scan) in diagnosis of brain trauma is well established and ct of the brain is a choice method. finding lesion in brain traumatic patient is very important so goal of this study is finding of brain ct scan in traumatic patient...

PURPOSE To compare the dose and image quality of a standard dose abdominal and pelvic CT with Filtered Back Projection (FBP) to low-dose CT with Adaptive Iterative Dose Reduction 3D (AIDR 3D). MATERIALS AND METHODS We retrospectively examined the images of 21 patients in the portal phase of an abdominal and pelvic CT scan before and after implementation of AIDR 3D iterative reconstruction. Th...

BACKGROUND Despite its superb lateral resolution, flat-panel-detector (FPD) based tomosynthesis suffers from low contrast and inter-plane artifacts caused by incomplete cancellation of the projection components stemming from outside the focal plane. The incomplete cancellation of the projection components, mostly due to the limited scan angle in the conventional tomosynthesis scan geometry, oft...

introduction bolus is a soft and resilient material which is used for increasing skin dose or to even out the irregular patient contour. the main property of various materials used presently as bolus is the water-equivalent electron density. ethyl methacrylate is used as a soft-liner in dentistry and its physical and chemical properties are proved to be nontoxic for human body. the goal of this...
