Review Meta AnalysisDiagnostic value of whole-body magnetic resonance imaging for bone metastases: a systematic review and meta-analysis.
To assess the overall diagnostic accuracy of whole-body magnetic resonance imaging (WB-MRI) in detecting bone metastases with a meta-analysis. ⋯ WB-MRI was an accurate, cost-effective tool in detecting bone metastases. WB-MRI without DWI may improve the specificity of detecting bone metastases. DWI seems to be a sensitive but rather unspecific modality for the detection of bone metastatic disease. High-quality prospective studies regarding WB-MRI in detecting bone metastases still need to be conducted.

ReviewComputed tomography and magnetic resonance imaging in cystic fibrosis lung disease.
Computed tomography (CT) is the current "gold standard" for assessment of lung morphology and is so far the most reliable imaging modality for monitoring cystic fibrosis (CF) lung disease. CT has a much higher radiation exposure than chest x-ray. The cumulative radiation dose for life-long repeated CT scans has limited its use for CF patients as their life expectancy increases. ⋯ It is thought to be less sensitive to detect small airway disease. At the same time, MRI is superior to CT when it comes to the assessment of functional changes such as altered pulmonary perfusion. The recommendation is to further reduce radiation dose related to the use of CT and to use MRI in the follow-up of morphological changes where possible.

ReviewRecent technological and application developments in computed tomography and magnetic resonance imaging for improved pulmonary nodule detection and lung cancer staging.
This review compares the emerging technologies and approaches in the application of magnetic resonance (MR) and computed tomography (CT) imaging for the assessment of pulmonary nodules and staging of malignant findings. Included in this review is a brief definition of pulmonary nodules and an introduction to the challenges faced. We have highlighted the current status of both MR and CT for the early detection of lung nodules. ⋯ Recent advancements linking in vivo imaging to corresponding histological pathology are also highlighted. In vivo imaging plays a pivotal role in the clinical staging of pulmonary nodules through TNM assessment. While CT and positron emission tomography (PET)/CT are currently the most commonly clinically employed modalities for pulmonary nodule staging, studies are presented that highlight the augmentative potential of MR.

ReviewCommon data elements in radiologic imaging of traumatic brain injury.
Traumatic brain injury (TBI) has a poorly understood pathology. Patients suffer from a variety of physical and cognitive effects that worsen as the type of trauma worsens. ⋯ Technical details regarding state-of-the-art protocols for both MRI and CT are also presented with the hope of guiding current and future research efforts as to what is possible in the field. Stress was also placed on the potential to create a database of CDEs as a means to best record information from a given patient from the reading of the images.
