Meta Analysis Comparative Study18 FDG PET and PET-CT for the detection of bone metastases in patients with head and neck cancer. A meta-analysis.
We performed a meta-analysis to evaluate (18) FDG PET/PET-CT for the detection of bone metastases in patients with head and neck cancer. ⋯ (18) FDG PET and PET-CT have high sensitivity and accuracy for the detection of bone metastasis in patients with head and neck cancer.

Cost analysis of intracranial aneurysmal repair by endovascular coiling versus flow diversion: at what size should we use which method?
Flow diverters enable intracranial aneurysmal repair without the need to enter the aneurysm sac. Concerns, however, have been raised regarding the cost compared with coiling techniques. The aim of this study was to evaluate the relative costs for different aneurysm sizes to ascertain if different sizes are more cost-effectively treated by a particular method. ⋯ Given the price parity threshold crossed for aneurysms >12 mm requiring stent assistance and the relative ease of the flow diverter technique, we suggest that flow diversion should be considered the first-line treatment for aneurysms in this category.

Five-year analysis of magnetic resonance imaging as a screening tool in women at hereditary risk of breast cancer.
Women at very high risk of breast cancer are recommended to undertake enhanced surveillance with annual MRI in addition to mammography. We aimed to review the performance of breast MRI as a screening modality over its first 5 years at our institution. ⋯ Breast MRI as a screening modality for malignant lesions in women with high hereditary risk is valuable. The recall rate, especially in the prevalent round, improved with radiologist experience.

Ultrashort time-to-echo MRI of the cartilaginous endplate: technique and association with intervertebral disc degeneration.
The purpose of this study was to report the feasibility of the ultrashort time-to-echo (UTE) MRI technique to assess cartilaginous endplate (CEP) defects in humans in vivo and to assess their relationship with intervertebral disc (IVD) degeneration. ⋯ Our study demonstrates the feasibility of using UTE MRI in humans in vivo to assess the integrity of the CEP. A statistically significant association was found to exist between the presence of CEP defects and IVD degeneration. In the lower lumbar region, more severe degeneration was found to occur in the IVDs with CEP defects than in those without defects.

Comparative Study Controlled Clinical TrialSupplemental value of diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) technique to whole-body magnetic resonance imaging in detection of bone metastases from thyroid cancer.
We compared the efficacy of whole-body MRI (WBMRI) with and without diffusion-weighted whole-body imaging with background body signal suppression (DWIBS) using a 3.0-T MR scanner to [18F] fluoro-2-D-glucose positron emission tomography with CT (integrated FDG-PET/CT) for the detection of bone metastases in patients with differentiated thyroid carcinoma (DTC). ⋯ Adding DWIBS improved the sensitivity and the overall accuracy of WBMRI using 3.0-T MRI for the detection of bone metastases in patients with DTC. There was no statistically significant difference in diagnostic accuracy between MRI with DWIBS and integrated FDG-PET/CT.
