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
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.

To evaluate the accuracy of depth measurements on supine chest computed tomography (CT) for transthoracic needle biopsy (TNB). ⋯ Skin-lesion depths measured on prebiopsy supine chest CT scans were inaccurate for TNB in the prone position, particularly for nodules in the upper and middle lung zones.

Review Meta Analysis
The role of arterial embolization in controlling pelvic fracture haemorrhage: a systematic review of the literature.
To evaluate the efficacy of emergency transcatheter arterial embolization (TAE) in controlling retroperitoneal arterial haemorrhage associated with unstable pelvic fractures. ⋯ TAE is an efficient acute intervention for controlling severe arterial bleeding related to pelvic trauma with a low complication rate. Repeat of the procedure is occasionally necessary before the effective haemorrhage control.
