To investigate high resolution computed tomography (HRCT) and pulmonary function indices (PFTs) for determining prognosis in patients with chronic fibrotic hypersensitivity pneumonitis (CHP). ⋯ • HRCT is increasingly used to assess chronic fibrotic hypersensitivity pneumonitis. • HRCT patterns are superior to pulmonary function tests for predicting mortality. • Extensive traction bronchiectasis strongly predicts poor survival in chronic hypersensitivity pneumonitis.

To investigate the diagnostic accuracy, through quantitative analysis, of contrast-enhanced ultrasound (CEUS), using a microbubble contrast agent, in the differentiation of thyroid nodules. ⋯ • Contrast-enhanced ultrasound (CEUS) helps differentiate between benign and malignant thyroid nodules. • Quantitative CEUS analysis yields sensitivity of 76.9% and specificity of 84.8%. • CEUS may be a potentially useful adjunct in assessing thyroid nodules.

This study evaluated patients with multiple sclerosis using diffusion tensor imaging (DTI) to obtain fractional anisotropy (FA) and mean diffusivity (MD) values. ⋯ Magnetic resonance imaging is widely performed in multiple sclerosis (MS) patients Diffusion tensor imaging (DTI) can be implemented using a 3T magnet DTI provides quantitative parameters as mean diffusivity (MD) and fractional anisotropy (FA) MD and, especially, FA can help evaluate the lesion load in MS patients and also assess variation in normal appearing white matter (NAWM) in MS.

Multicenter Study
Impact of 64-slice coronary CT on the management of patients presenting with acute chest pain: results of a prospective two-centre study.
Our two-centre prospective study evaluates the usefulness of 64-slice coronary computed tomography (CCT) to rule out significant coronary artery stenosis in patients admitted in emergency departments (ED) for acute coronary syndromes (ACS) with low-to-intermediate risk score. ⋯ • 64-slice coronary computed tomography (CCT) offers a critical role in acute chest pain. • 64-slice CCT allows differentiation between significant and non-significant coronary artery stenosis. • Normal 64-slice CCT allows rapid discharge of patients with ACP. • 64-slice CCT helps make appropriate therapeutic decision in patients with ACP.

Comparative Study
Time-resolved MR angiography of the intracranial venous system: an alternative MR venography technique.
To compare time-resolved imaging of contrast kinetics (TRICKS) magnetic resonance angiography (MRA) with two-dimensional time-of-flight (TOF) magnetic resonance venography (MRV), and three-dimensional contrast-enhanced (CE) MRV in the visualisation of normal cerebral veins and dural venous sinuses. ⋯ • Time resolved magnetic resonance angiography can image the intracranial venous system dynamically • It seems comparable to contrast-enhanced MRV techniques in venous visualisation • The optimal phase for venous structures can be chosen from the dynamic data set • The diagnostic performance in venous thrombosis requires further research.
