BACKGROUND/AIMS Common bile duct stones are associated with the extent of dilation of the common bile duct as well as its angulation. Multidetector computed tomography (MD CT) has a good resolution for the definition of the anatomical features of the common bile duct. METHODS The multiplanar reformation images of 398 patients that underwent multidetector CT for the diagnosis of disorders not ...

PURPOSE To identify factors that affect functional outcome one year after distal radial fracture treatment. METHODS 521 women and 121 men aged 16 to 92 (mean, 59) years with distal radial fractures underwent external fixation (n=123), open reduction and internal fixation (n=63), a combination of both (n=10), distal radial osteotomy for symptomatic malunion (n=90), or casting with (n=194) or w...

introduction radiographs provide unique information about the status of periodontium and permanent records of condition of bone throughout the course of the disease. interproximal images record the distance between the cementoenamel junction and the crest of the interradicular alveolar bone, more accurately. the aim of this study was to investigate the effect of different vertical angles of x-r...

OBJECTIVES The aim of this study was to perform an investigation of the effects of the longitudinal straightening of coronary arteries by stents and the possible association with major adverse cardiac events (MACE) (primary end point) and angiographic restenosis (secondary end point). BACKGROUND Stent deployment straightens a tortuous artery, and any consequent arterial longitudinal stretch m...

For k ≥ 3, a k-angulation is a 2-connected plane graph in which every internal face is a k-gon. We say that a point set P admits a plane graph G if there is a straight-line drawing of G that maps V (G) onto P and has the same facial cycles and outer face as G. We investigate the conditions under which a point set P admits a k-angulation and find that, for sets containing at least 2k2 points, th...

BACKGROUND The clinical diagnosis of thumb ulnar collateral ligament disruption has been based on joint angulation during valgus stress testing. This report describes a definitive method of distinguishing between complete and partial ulnar collateral ligament injuries by quantifying translation of the proximal phalanx on the metacarpal head during valgus stress testing. METHODS Sixty-two cada...

background : retakes of intra oral radiographs happen frequently in dental practice although radiographic courses train dental students in consecutive semesters. to reduce the patient exposure as much as possible it is mandatory to reduce the number of retakes both in radiology clinics and educational centers. materials and methods : 3188 periapical radiographs taken by bisect-angle technique w...

External fixation correction of angular deformities leads to secondary translation deformities when occurring around an axis located proximal or distal to the center of rotation of angulation (CORA); secondary length deformities result when correction occurs around an axis concave or convex to the CORA. With circular fixation, the hinge axis can be matched to the CORA. With monolateral fixation...
