Comparative StudyWhole-body magnetic resonance imaging for detecting bone metastases: comparison with bone scintigraphy.
The aim of the study was to assess the reliability of whole-body magnetic resonance imaging (WB-MRI) in detecting skeletal metastasis and to compare the results with those of bone scintigraphy (BS). ⋯ WB-MRI is a reliable method for screening patients with suspected skeletal metastases, although BS still remains a useful tool. WB-MRI is also advantageous because it reveals extraskeletal and soft tissue metastases.

Comparative StudyFocal liver lesions in cirrhosis: value of contrast-enhanced ultrasonography compared with Doppler ultrasound and alpha-fetoprotein levels.
This study aimed to evaluate the diagnostic value of contrast-enhanced ultrasound (CEUS) in characterising focal liver lesions in cirrhosis and to validate its use in lesions discovered during surveillance for hepatocellular carcinoma (HCC). ⋯ CEUS can characterise focal liver lesions with 96.6% accuracy, a value higher than US, Doppler US, AFP levels, combined US and AFP levels and combined US and Doppler US. CEUS should therefore be used to characterise focal liver lesions detected during HCC surveillance of cirrhotic patients.

Comparative StudyCementoplasty in the management of painful extraspinal bone metastases: our experience.
The aim of this study was to demonstrate the effectiveness of interventional techniques in the palliative management of painful extraspinal bone metastases. ⋯ In our experience, cementoplasty alone for small lesions or combined with RF ablation in larger lesions is an effective and safe therapy in the palliative management of painful extraspinal bone metastases.

Comparative StudyHow much do GOLD stages reflect CT abnormalities in COPD patients?
Severity of chronic obstructive pulmonary disease (COPD) can be graded using the classification released in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) report. Such classification is essentially based on spirometry and does not recognise the role of other measures. The aim of this study was to assess whether the GOLD stages correlate with the extent of pulmonary emphysema and other ancillary computed tomography CT features in a population of smokers with stable COPD. ⋯ Although we found a significant correlation between CT emphysema extent and GOLD stages, different percentage of emphysema extent can be observed among each GOLD stage. The upper limit of 31.5% of emphysema extent may indicate a boundary for a clinically worsening status.

Editorial Historical ArticleNotes on the history of the radiological study of Egyptian mummies: from X-rays to new imaging techniques.
A few centuries after the practice of mummification was finally abolished in the seventh century A. D., mummies began to capture the collective imagination, exerting a mysterious fascination that continues to this day. From the beginning, the radiological study of Egyptian mummies permitted the collection not only of medical data but also of anthropological and archaeological evidence. ⋯ CT images can be used to obtain a three-dimensional reconstruction of the mummy that provides important new information, in part thanks to the virtual endoscopy technique known as "fly through". Moreover, starting from CT data and using sophisticated graphics software, one can reconstruct an image of the face of the mummified individual at the time of his or her death. The history of imaging, from its origins until now, from the simplest to the most sophisticated technique, allows us to appreciate why these studies have been, and still are, fundamental in the study of Egyptian mummies.
