Comparative effectiveness research: alternatives to "traditional" computed tomography use in the acute care setting.
The goal was to seek consensus in identifying and prioritizing research questions and themes that involve the comparative effectiveness of "traditional" computed tomography use versus alternative diagnostic strategies in the acute care setting. A modified Delphi technique was used that included input from emergency physicians, emergency radiologists, medical physicists, and an industry expert to achieve this.

Comprehensive appraisal of magnetic resonance imaging findings in sustained rheumatoid arthritis remission: a substudy.
This study evaluated the effect of sustained American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) Boolean remission on residual joint inflammation assessed by magnetic resonance imaging (MRI) and to secondarily
evaluate other clinical definitions of remission, within an early seropositive rheumatoid arthritis (RA) cohort. It found that total MRI inflammatory scores (tenosynovitis, synovitis, osteitis) were lower among patients in clinical remission. Lower MRI scores were correlated with longer duration of Clinical Disease Activity Index (CDAI) remission.

Imaging techniques for the diagnosis of hepatocellular carcinoma: a systematic review and meta-analysis.
This review evaluated the test performance of ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) in the detection of hepatocellular carcinoma (HCC). It concluded that CT and MRI are associated with higher sensitivity than ultrasonography without contrast for detection of HCC. For detection of focal liver lesions, the sensitivities of all three techniques are similar.

Comparative effectiveness of imaging modalities to determine metastatic breast cancer treatment response.
This literature review evaluates studies regarding the effectiveness of different imaging modalities in evaluating treatment response among metastatic breast cancer patients. The review of the literature demonstrates a current paucity of evidence regarding the use of imaging for treatment evaluation of metastatic lesions among breast cancer patients.
