PURPOSE To compare anatomic, radiographic, and computed tomographic (CT) measurements of the proximal femur in an Indian population. METHODS 26 left and 24 right dried cadaveric femurs were obtained. Each femur was divided into segments at 10 cross-sectional levels from proximal to distal. At each level, anteroposterior (AP), lateral, 45-degree internal oblique, and 45-degree external oblique...

BACKGROUND The sagittal diameter of the cervical spinal canal is of clinical importance in traumatic, degenerative, and inflammatory conditions. A small canal diameter has been associated with an increased risk of injury; however, there is a lack of reliable normative data on spinal canal diameters in different age groups in the United States population. The purpose of this study was to use dir...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 60-year-old woman showed blackish pigmentation around both eyes for 2 years, with clinical examination revealing waxy hyperpigmentation and small nodules (A). 12.7 mg/dL; and 24-hour urinary protein, 75 mg. A peripheral blood smear showed normocytic, normo...

OBJECTIVE To evaluate and compare the diagnostic efficiency of a digital radiographic system (RadioVisioGraphy -RVG-) in combination with a diagnostic assisting program (Logicon) with RVG in basic mode, magnification and conventional radiography (Kodak). STUDY DESIGN A study was made of 384 proximal surfaces corresponding to 192 posterior teeth. The diagnostic techniques employed comprised Ko...

Introduction: Variable resolution x-ray (VRX) CT is a new type of CT that can image objects at various spatial resolutions. In a VRX CT scanner, the spatial resolution increases at the cost of reduction in the field of view (FOV). An important factor that limits the spatial resolution of the VRX CT is the effect of focal spot size. Also, the optimum magnification is different at each incident a...

Preoperative planning is of paramount importance in obtaining reproducible results in modern hip arthroplasty. Planning helps the surgeon visualize the operation after careful review of the clinical and radiographic findings. A standardized radiograph with a known magnification should be used for templating. The cup template should be placed relative to the ilioischial line, the teardrop, and t...

In this paper, a defect grading method for digital radiographic images from CMOS x-ray linear array detector was put forward, which is based on a standard defect-grading comparison sample and a computer-aided defect interpretation method. A standard defect-grading comparison sample was designed and used to help measuring the distortion and magnification of the images, and to grade the defects i...
