Helical CT with only colonic contrast material for diagnosing diverticulitis: prospective evaluation of 150 patients.
We prospectively evaluated a helical CT technique in which contrast material is administered only through the colon for the imaging of suspected diverticulitis. ⋯ Helical CT obtained after contrast material administered only through the colon is accurate (99%) for confirming or excluding clinically suspected diverticulitis and for suggesting alternative conditions (78%) when they are present. This CT technique avoids the risks, discomforts, and costs of oral and i.v. contrast material administration and allows immediate scanning.

Peripherally inserted central venous catheters: factors affecting patient satisfaction.
We studied factors that affect satisfaction of patients who have undergone placement of peripherally inserted central venous catheters (PICCs) by interventional radiologists and patients' willingness to undergo placement of future PICCs. ⋯ PICC placement above the elbow is more acceptable to patients than placement at the elbow. PICC placement above the elbow and patients' perception of less interference by the PICC with activities of daily living are positively related to patient willingness to undergo future PICC placement.

Central venous access: low internal jugular vein approach using imaging guidance.
The use and safety of a low internal jugular vein cannulation technique for central venous access was prospectively evaluated. ⋯ The inferior internal jugular vein provides a safe and direct route to the superior vena cava and right atrium for central venous access. Use of an internal jugular vein cannulation site at the base of the neck avoids kinking of tunneled and untunneled catheters.
