To determine the relationship of increasing body mass index (BMI) and abdominal fat on the effective dose acquired from computed tomography (CT) abdomen and pelvis scans. ⋯ Increasing BMI and abdominal fat significantly increases the effective dose received from CT abdomen and pelvis scans.

Sevoflurane anesthetic has recently been administered by anesthesiologists during voiding cystourethrograms in a centre where radiologists are not permitted to deliver pediatric sedation. ⋯ No adverse events or effects on diagnostic quality of the pediatric voiding cystourethrogram were encountered when using sevoflurane. The majority of surveyed caregivers thought that anesthesia made voiding cystourethrography an easier experience for their child.

Multicenter Study
Changing radiation dose from diagnostic computed tomography examinations in Saskatchewan.
Follow-up study to observe if provincial mean effective radiation dose for head, chest, and abdomen-pelvis (AP) computed tomographies (CTs) remained stable or changed since the initial 2006 survey. ⋯ Significant dose and variation reduction was seen for single-phase CT chest and AP examinations between 2006 and 2008, whereas CT head dose increased over the same interval. These changes, combined with increased utilisation, resulted in per capita increase in radiation dose from CT between the 2 studies.

To document the prevalence and pattern of risk factors for contrast-induced nephrotoxicity (CIN) in an outpatient population referred for contrast-enhanced computed tomography (CT) (CECT) studies. ⋯ In an ambulatory outpatient population, many patients presenting for outpatient CECT studies will have risk factors for CIN or for kidney function impairment (low eGFR) at baseline. Kidney function assessment, therefore, is indicated in this patient population before CECT.

In the intensive care unit (ICU), prognosticating patients who are comatose or defining brain death can be challenging. Currently, the criteria for brain death are clinical supported by paraclinical tests. Noncontrast computed tomography (CT) shows diffuse loss of grey-white differentiation consistent with infarction. We hypothesize that the extent of hypodensity is predictive of poor neurologic outcome or brain death. ⋯ Diffuse loss of grey-white matter differentiation is subtle but specific for poor neurologic outcome, which may allow earlier prognostication of patients in whom clinical parameters are difficult to assess.
