Comparative StudyMean bronchial wall attenuation value in chronic obstructive pulmonary disease: comparison with standard bronchial parameters and correlation with function.
The objective of our study was to evaluate bronchial wall attenuation values quantified using CT in patients with chronic obstructive pulmonary disease (COPD). ⋯ The bronchial wall attenuation value is a powerful index for assessing tobacco-related bronchial wall changes in patients with COPD.

Comparative StudyIntraindividual comparison of gadobutrol and gadopentetate dimeglumine for detection of myocardial late enhancement in cardiac MRI.
Gadobutrol is an extracellular macrocyclic gadolinium chelate recently introduced in MRI, and it has already been used for cardiac late enhancement imaging; however, until now it has never been compared with gadopentetate dimeglumine. The purpose of our study was to compare 0.1 mmol/kg gadobutrol to 0.2 mmol/kg gadopentetate dimeglumine for the detection of myocardial late enhancement in the same group of patients. ⋯ A single dose of gadobutrol seems to be as effective as a double dose of gadopentetate dimeglumine for the detection of late enhancement.

Inadvertent ingestion of wire bristles from a grill cleaning brush: radiologic detection of unsuspected foreign bodies.
We report acute onset of either odynophagia or abdominal pain immediately after ingestion of grilled meat in six patients presenting between May 1, 2009, and November 18, 2010. In all six patients, radiologic studies revealed a linear metallic foreign body. Careful history revealed cleaning of the grill with a metallic brush immediately before cooking in all six cases. ⋯ Physicians should be aware of this potential hazard to facilitate accurate and timely diagnosis.

The objective of our study was to identify the significance of lung nodules reported on abdominal CT. ⋯ Lung nodules incidentally detected on abdominal CT were rarely malignant and were seen only in the setting of an underlying abdominal malignancy. Knowledge of such history is of critical importance to both the clinician and the radiologist. Dedicated chest CT is most useful when assessing pulmonary nodules in patients with localized malignancy.
