Comparative StudyNon-breath-hold fast spin-echo versus breath-hold fast spin-echo and spoiled gradient-recalled echo MR imaging in the detection of hepatic tumors: correlation with surgical findings.
Our objective was to compare the sensitivity of non-breath-hold T2-weighted fast spin-echo with and without fat suppression, breath-hold T2-weighted fast spin-echo without fat suppression, and spoiled gradient-recalled echo (GRE) MR imaging for detecting hepatic tumors using surgical findings as the standard of reference. ⋯ Gadolinium chelate-enhanced spoiled GRE imaging is more sensitive than T2-weighted MR imaging obtained with a breath-hold or a non-breath-hold technique.

Safety and efficacy of sedation in children using a structured sedation program.
The purpose of this study was to evaluate the safety and efficacy of sedating pediatric outpatients in a radiology department using a structured sedation program modeled after the guidelines of the American Academy of Pediatrics. ⋯ Sedation of children can be done in a safe and highly efficacious manner in a hospital radiology department using a structured sedation program modeled after the guidelines of the American Academy of Pediatrics.

The purpose of this study was to evaluate the usefulness of MR imaging in revealing occult fractures in patients with clinically suspected acute scaphoid fractures who have normal or equivocal findings on radiographs. ⋯ MR imaging can reveal occult wrist fractures when findings on radiographs are normal or equivocal.

Placement of long-term central venous catheters in outpatients: study of 134 patients over 24,596 catheter days.
Our goal was to investigate the feasibility of inserting long-term central venous access devices in outpatients using a simple technique that minimizes the risks of complications linked to venipuncture and errors in management. ⋯ Outpatient CVC placement is feasible because the procedure is not adversely affected when the patient is not hospitalized. The drawbacks are identical to those faced by inpatients. Improved materials and more extensive information on the management of patients with long-term CVCs would help reduce complications further.
