We sought to determine the current and anticipated future status of anatomy education in medical schools in North America, with particular emphasis on the role of radiologists and imaging in the curriculum. ⋯ The role of radiologists will probably increase in future teaching of anatomy.

Comparative Study Clinical Trial
Low-dose gadobenate dimeglumine versus standard-dose gadopentate dimeglumine for delayed contrast-enhanced cardiac magnetic resonance imaging.
The purpose of our study was to compare gadopentate dimeglumine (Gd-DTPA) and gadobenate dimeglumine (Gd-BOPTA) for the evaluation of myocardial infarction (MI) and in the grading transmural extent on late-contrast enhanced cardiac magnetic resonance imaging. ⋯ According to our data, the diagnostic efficacy of 0.1 mmol/kg dose Gd-BOPTA is equivalent to that of 0.2 mmol/kg Gd-DTPA for the assessment of MI on delayed enhanced magnetic resonance images.

Controlled Clinical Trial
Contrast/Noise ratio on conventional MRI and choline/creatine ratio on proton MRI spectroscopy accurately discriminate low-grade from high-grade cerebral gliomas.
Histopathology is the gold standard to establish the grade of brain tumors but biopsy and/or surgery are not always possible. The aim of this study is to determine whether histological grade of tumors may be predicted by means of conventional gadolinium-enhanced MRI and proton magnetic resonance spectroscopy (MRS). ⋯ The intensity of contrast enhancement measured with the CNR, the choline/creatine ratio, and the presence of lactate were the most powerful variables to predict malignancy in brain tumors. The CNR is a simple, objective, and useful tool in the initial assessment of gliomas and metastases.

The aim of the study is to evaluate the effectiveness of an Emergency Radiology (ER) Core Curriculum training module and a Digital Imaging and Communications in Medicine (DICOM)-based interactive examination system to prepare first-year (postgraduate year 2 [PGY-2]) radiology residents and assess their readiness for taking overnight radiology call. ⋯ First-year radiology residents who underwent 6 months of formal radiology training followed by an intensive ER lecture series before taking overnight call had scores similar to upper-level colleagues on an interactive computer-based ER simulation module.

The imaging systems and protocols used during ventilation-perfusion lung (V-P) scintigraphy and computed tomographic (CT) pulmonary angiography (CTPA) can affect diagnostic performance. We investigated the level of awareness of these factors among US clinicians who refer patients for imaging for suspected acute pulmonary embolism. ⋯ Although state-of-the-art equipment is important to them, clinicians practicing in the United States have limited knowledge of the equipment being used during CTPA and V-P scintigraphy scanning in their communities. Radiologists should intensify efforts to familiarize their clinical colleagues with the equipment they use.
