Several other methods of achieving dynamic range control were also discussed in the previous chapter. These methods are typically unsharp mask filters with large kernel sizes, and multi-scale approaches such as multi scale image contrast amplification (MUSICA) developed by the Agfa-Gevaert company (Vuylsteke & Schoeters, 1999). In achieving their goal of dynamic range control, these methods alt...

This paper describes opacification and identification of two surgically constructed pancreatico-jujunal shunts. A fibreoptic panendoscope was used with retrograde injection via the ampulla of Vater (ERCP). This procedure makes possible more accurate anatomical evaluation and so more precise clinical appraisal of both pre- and post-surgical states.

Esophageal atresia without tracheoesophageal fistula is a rare esophageal anomaly in children. We have successfully applied three-dimensional technique of computed tomography on four consecutive babies with this anomaly in order to accurately measure the length of the gap between the two esophageal segments, which is important for preoperative plan and the feasibility and timing of delayed prim...

Background: Evaluation of the accurate position after radial head arthroplasty remains a challenge for surgeons.Standard radiographs are used to evaluate the position of the implant, however, results regarding radiographicdeficiencies on clinical outcome are not consistent. In this retrospective study our main aim was to determine if subtleradiographic deficiencies after radia...

Acquisition and interpretation of equine skull radiographs is notoriously difficult. However, by dividing the skull into anatomic regions and considering the radiographic appearance of various pathologic changes that occur in these regions, the process of evaluation becomes simpler. This report aims to review acquisition of skull radiographs and radiographic appearance of various diseases in or...

Methods A total of 6824 children (3477 boys and 3347girls) aged from 6 to 17 years old recruited from 352 classes of primary schools, and junior and senior high schools were screened for scoliosis. 442 children showed physical signs of potential scoliosis (Angle of Trunk Rotation at Adam’s forward bending test of five degrees or more) and were referred for posteroanterior radiographic evaluatio...

cent hemithorax is seen at frontal chest radiography are often encountered. Because such an abnormality is related to various conditions, including radiographic artifacts, chest wall abnormalities, pulmonary vascular disorders with reduced perfusion, and lung parenchymal abnormalities with air trapping or compensatory overexpansion, a radiographic finding of increased radiolucency involving one...
