Abstract:

Objectives: Aspirated objects generally represent items accessible to children. When metallic candy wrapper aspiration is questioned, radiographic studies may aid diagnosis. An infant with repeated chest radiographs negative for a metallic foreign body was found to have a multi-layer metallic candy wrapper in the left main bronchus. The purpose of this study was to determine whether conventional and dual-energy radiographic techniques exclude the presence of aspirated metallic foil wrappers. Methods: Single-layer and multi-layer metallic candy wrappers were radiographically studied with conven

The study also evaluated inter-observer and intra-observer reliability during repeated assessments. Material and Methods Marginal bone around 29 implants in 17 patients was assessed using standardized digital intraoral and digital panoramic radiographs. Two observers evaluated bone level by noting the thread at which marginal bone seemed to be attached at distal and mesial surfaces of the implant

Abstract:

The authors present their radiographic criteria for assessing fusion of the lumbar spine after anterior interbody fusion with intradiscal implants. These criteria include the assessment of plain radiographs, dynamic motion radiographs, and thin-cut computerized tomography scans. Fusion within the instrumented spinal motion segment can be determined using radiographic evaluation to assess spinal alignment on sequential examinations, angular and translational changes on dynamic motion studies, and device–host interface, and to identify new bone formation and bone remodeling.

Background Dorsal/volar tilt is an important radiographic measurement commonly included in the treatment decision of distal radius fractures (DRFs). However, studies have shown that forearm positioning relative to rotation (i.e., supination and pronation) can affect the measured tilt value but with substantial interobserver variance. Purpose To examine whether interobserver agreement on radiographic tilt measurement is influenced by forearm rotation. Material and Methods We radiographed 21 cadaveric forearms at 5° rotational intervals between 15° supination and 15° pronation on lateral radiogr

Abstract:

Radiographic examinations are used to discover and define the type and extent of disease in many clinical situations. Currently, it is common for dental patients to receive dental radiographic examinations on a routine schedule with little variation in spite of different patient signs and symptoms. Such routine scheduling of radiographic examinations may result in unnecessary patient exposure. There is also the possibility of under-utilization of radiography; this can result in inadequate or excessively delayed diagnosis. Patient selection criteria are descriptions of clinical conditions deriv

Congenital vertebral malformations (CVM) are common in brachycephalic ‘screw-tailed’ dogs; they can be associated with neurological deficits and a genetic predisposition has been suggested. The purpose of this study was to evaluate radiography as a screening method for congenital thoracic vertebral malformations in brachycephalic ‘screw-tailed’ dogs by comparing it with CT. Forty-nine dogs that had both radiographic and CT evaluations of the thoracic vertebral column were included. Three observers retrospectively reviewed the images independently to detect CVMs. When identified, they were clas

Abstract:

Consistently accurate radiographic diagnosis of talocalcaneal tarsal coalitions is difficult because of the complex anatomy of the subtalar articulations. Standard techniques that include special radiographic views and plain tomography are useful but often inconclusive. In this study, computerized tomography (CT) was used to evaluate suspected talocalcaneal coalitions in patients with the clinical diagnosis of peroneal spastic flatfoot. CT demonstrated bony and nonbony coalitions in 14 of 22 patients studied. In the remaining eight patients, CT effectively ruled out the diagnosis of subtalar c

All measurements, with the exception of ventrodorsal depth, correlated significantly (P < 0.05) with liver weight and volume.
