Review Meta Analysis
A meta-analysis of ¹⁸FDG-PET-CT, ¹⁸FDG-PET, MRI and bone scintigraphy for diagnosis of bone metastases in patients with lung cancer.
Lung cancer is the most common cause of cancer related death among both men and women worldwide. The skeleton is the most common site of cancer metastasis. Early detection is crucial for prognosis. To evaluate and compare the capability for bone metastasis assessment of [(18)F] fluoro-2-d-glucose positron emission tomography with computed tomography ((18)FDG-PET-CT), [(18)F] fluoro-2-d-glucose positron emission tomography ((18)FDG-PET), magnetic resonance imaging (MRI) and bone scintigraphy (BS) in lung cancer patients, a meta-analysis is preformed. ⋯ The results showed that both (18)FDG-PET-CT and (18)FDG-PET were better imaging methods for diagnosing bone metastasis from lung cancer than MRI and BS. (18)FDG-PET-CT has higher diagnostic value (sensitivity, specificity and DORs) for diagnosing bone metastasis from lung cancer than any other imaging methods.

Comparative Study
Analysis of eighty-one cases with breast lesions using automated breast volume scanner and comparison with handheld ultrasound.
This study aims to evaluate the clinical utility of automated breast volume scanner (ABVS) against handheld ultrasound in detecting and diagnosing breast lesions. ⋯ Automated breast volume scanner provides advantages of high diagnostic accuracy, better lesion size prediction, operator-independence and visualization of the whole breast. It is a promising modality in breast imaging.

Comparative Study
Comparison of capability of dynamic O₂-enhanced MRI and quantitative thin-section MDCT to assess COPD in smokers.
The purpose of this study was to directly and prospectively compare the capability of dynamic O(2)-enhanced MRI and quantitatively assessed thin-section MDCT to assess smokers' COPD in a large prospective cohort. ⋯ Dynamic O(2)-enhanced MRI for assessment of COPD in smokers is potentially as efficacious as quantitatively assessed thin-section MDCT.

There is a potential risk of aneurysm rupture after parent artery revascularization because of increased blood flow. The purpose of this study is to assess the efficacy and safety of Wingspan stent-assisted coil embolization in the treatment of intracranial aneurysms with symptomatic parent artery stenosis. ⋯ We found that the Wingspan stent-assisted coil embolization was helpful in the treatment of intracranial aneurysms with parent artery stenosis.

The aim of this study was to explore the relationship of scanning parameters (clinical protocols), reconstruction kernels and slice thickness with image quality and radiation dose in a DSCT. ⋯ The clinical protocol, reconstruction kernel, slice thickness and phantom diameter or the density of material it contains directly affects the image quality. Dual energy protocol shows the lowest dose-length-product compared to all other protocols examined, the fused image shows excellent image quality and the noise is same as that of single or high-pitch mode protocol images. Advanced CT technology improves image quality and considerably reduces radiation dose.
