The effect of international teleradiology attending radiologist coverage on radiology residents' perceptions of night call.

PURPOSE: The purpose of this study was to determine the effects of international teleradiology attending radiologist coverage (ITARC) of emergency examinations on radiology residents' perceptions of night call. METHODS: A survey was administered at 2 different radiology residency programs that have attending radiologists who cover the night shift via teleradiology from Israel 5 nights per week. The survey consisted of 12 questions concerning residents' education and anxiety during on-call shifts and the effects of ITARC on these aspects of residency training. The questions were answered on a scale ranging from 1 to 5, with 3 being neutral. RESULTS: The radiology residents felt that ITARC improved the on-call learning experience (score = 3.7; 1 = much worse, 5 = much improved). The residents felt neutral about the statements "Review of cases with the attending radiologist over the telephone is comparable educationally to having the attending radiologist in person at the workstation" (score = 3.0) and "Having an attending radiologist easily available diminishes the need for me to commit to a diagnosis on my own and is therefore detrimental to my education" (score = 2.9; 1 = strongly disagree, 5 = strongly agree). The residents' stress levels on call were high without ITARC (score = 1.8; 1 = very high, 5 = very low) and moderate with ITARC (score = 2.7). The residents' anxiety levels before a night on call were moderate without ITARC (score = 2.9; 1 = very high, 5 = very low) and low with ITARC (score = 3.7). CONCLUSIONS: Radiology residents felt that ITARC improved their educational experience. International teleradiology attending radiologist coverage also decreased radiology residents' stress and anxiety related to on-call shifts.

Multi-detector row CT urography in the evaluation of hematuria.

Hematuria can be well evaluated with a comprehensive contrast material-enhanced multi-detector row computed tomography (CT) protocol that combines unenhanced, nephrographic-phase, and excretory-phase imaging. Unenhanced images are obtained from the kidneys to the bladder and allow optimal detection of renal calculi, a common cause of hematuria. Renal parenchymal abnormalities, particularly masses, are best visualized on nephrographic-phase images, which also provide excellent evaluation of the other abdominal organs. Thin-section delayed images obtained from the kidneys to the bladder demonstrate the urinary tract distended with contrast material and are useful in detecting urothelial disease. Intravenous urography, ultrasonography, CT, retrograde ureterography and pyelography, cystoscopy, and ureteroscopy can all be used to evaluate patients with hematuria. In the past, a combination of several of these examinations was necessary to fully evaluate these patients. Now, however, this CT protocol may permit evaluation of hematuria patients with a single comprehensive examination, although more experience and data are needed to determine its efficacy in this setting.
