RSNA Centennial Article: Gone but Not Completely forgotten­ pictorial review of "antiquated" radiologic procedures [corrected].

The field of diagnostic and therapeutic radiology has always been characterized by constant innovation and creativity to evolve to its current form. There are numerous imaging techniques that were once prevalent but have become outdated and were replaced by the current examinations and modalities, which improve diagnostic accuracy and patient outcomes. Many of these outdated examinations were first described in the journal Radiology during its first 100 years of existence and were subsequently able to be disseminated across its vast readership to become the standard of care across the nation and the world. These earlier techniques, such as pneumoencephalography as it applies to neuroimaging and neurosurgery; kymography, a predecessor of cardiac imaging; contrast agents such as Thorotrast; and miscellaneous cultural tools, such as the shoe-fitting fluoroscope, left lasting impressions on the current practice of radiology and reflect a small subset of the imaging examinations of our predecessors. Knowledge of historic radiologic examinations and procedures is important to understand how we have arrived at the current practice of radiology we embrace today and how our field can continue to evolve to improve our diagnostic and therapeutic abilities to fit the changing needs of our patients.

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.
