Incidence of CT Contrast Agent-Induced Nephropathy: Toward a More Accurate Estimation.
Acute kidney injury is common among hospitalized patients and likely leads to inflated reports of the incidence of CT contrast agent-induced nephropathy as a cause of acute kidney injury. For a more accurate estimation, we compared the incidence of acute kidney injury immediately after contrast agent administration and a few days afterward in the same population. We also controlled for a creatinine level increase starting before and continuing after CT, which may be incorrectly associated with the scan itself. ⋯ There appears to be a minimal risk of CT contrast agent-induced nephropathy at mild to moderate levels of renal dysfunction.

Estimates of diagnostic reference levels for pediatric peripheral and abdominal fluoroscopically guided procedures.
The objective of our study was to survey radiation dose indexes of pediatric peripheral and abdominal fluoroscopically guided procedures from which estimates of diagnostic reference levels (DRLs) can be proposed for both a standard fluoroscope and a novel fluoroscope with advanced image processing and lower radiation dose rates. ⋯ Estimates of dose indexes of pediatric peripheral and abdominal fluoroscopically guided, clinical procedures should assist in the development of DRLs to foster management of radiation doses of pediatric patients.
