To determine the effect of baseline estimated glomerular filtration rate (eGFR) on causal association between intravenous iodinated contrast material exposure and subsequent development acute kidney injury (AKI) in propensity score-matched groups patients who underwent material-enhanced or unenhanced computed tomography (CT).This retrospective study was HIPAA compliant institutional review board approved. All contrast-enhanced (contrast group) (non-contrast CT 2000 2010 were identified...
To determine the risk of emergent dialysis and short-term mortality following intravenous iodinated contrast material exposure.This single-center retrospective study was HIPAA compliant institutional review board approved. All material-enhanced (contrast group) unenhanced (noncontrast abdominal, pelvic, thoracic computed tomography scans from 2000-2010 were identified. Patients in noncontrast groups compared propensity score-based 1:1 matching to reduce intergroup selection bias. with...
Based on a single clinical trial, it has been suggested that the contrast agent iodixanol, which is isotonic to human plasma, may be less nephrotoxic than other nonionic agents in renally impaired patients after intra-arterial injection. We compared effects renal function of iopamidol-370 injection (796 mOsm/kg) and iodixanol-320 (290 with chronic kidney disease undergoing contrast-enhanced multidetector computed tomography (CE-MDCT) examinations using multicenter, double-blind, randomized,...
The accuracy of coronal and sagittal magnetic resonance (MR) imaging was examined in the assessment rotational sideways displacements temporomandibular joint (TMJ) disk. Rotational disk displacement implies a combination anterior medial or lateral displacements, whereas pure without an component. Multiple 3-mm-thick MR images were obtained 18 fresh TMJ autopsy specimens compared with observations corresponding cryosections. correctly delineated mediolateral position 15 joints (83%)...
PURPOSE: To determine the weighted average sensitivity of magnetic resonance (MR) imaging in prospective detection acute neck injury and to compare these findings with those a comprehensive conventional radiographic assessment. MATERIALS AND METHODS: Conventional radiography MR were performed 199 patients presenting level 1 trauma center suspected cervical spine injury. Weighted sensitivities specificities calculated, across eight vertebral levels from C1 T1 was formed. Fourteen parameters...
The authors performed direct sagittal computed tomography (CT) on 4 cadaver temporomandibular joints (TMJ) and examined 51 TMJs in 47 patients clinically. results were correlated with anatomical sections clinical arthrographic findings. A fat plane between the bellies of lateral pterygoid muscles, termed "lateral pad," served as basis for detection internal derangements by CT. CT was 94% accurate detecting meniscal 96% degenerative arthritis. suggest that rather than arthrography be employed...
Internal derangements of the temporomandibular joint (TMJ) may be a significant factor in etiology painful dysfunction jaw and associated clinical symptoms. In two-year prospective investigation, 170 TMJs 85 patients were studied with plain tomography prior to arthrotomography. Arthritis was detected 19 (22%), predominantly second fourth decade life, which correlated internal depicted by arthrotomography, operative findings, histopathological examination condylar surface. The authors suggest...
Selective renal artery catheterization and angiography are commonly performed diagnostic procedures; however, the effects of these procedures on blood How (RBF) renin release have only been partially described. A biphasic RBF response has well documented during selective in dogs. The autoregulatory mechanisms governing responses uncertain. renin-angiotensin system major parameters contrast media, hypertonicity viscosity, suggested as important factors. In canine model, we examined acute...
Findings in 31 pediatric patients with pain and dysfunction of the temporomandibular joint (TMJ) are reported. The average age was 14 years (range, 8-16) duration symptoms 21.4 months 3 mo.-5 yr.). Internal derangements were found 29 (94%) degenerative arthritis 13 (42%). In 12 (39%), problem could be traced to an injury jaw. Secondary condylar hypoplasia associated meniscal abnormality (10%). Further awareness internal TMJ population should permit greater recognition their etiology. It is...
