To test the reliability of potentially new computed tomographic (CT) indicators of pulmonary hypertension (PH) and to establish whether a combination of CT and echocardiographic measurements was more predictive of PH than either test alone. ⋯ A combination of CT and echocardiographic markers of PH is more closely related to mPAP than either test in isolation.

To evaluate the relationship between nonalcoholic fatty liver disease (NAFLD) and coronary artery disease (CAD) and to define determinants of CAD in patients with or without metabolic syndrome. ⋯ Patients with NAFLD, even without metabolic syndrome, are at high risk for atherosclerosis. Assessment of NAFLD may be helpful for cardiovascular risk stratification.
-
To evaluate a technique to perform fluoroscopically directed thoracic transforaminal epidural injections. ⋯ This study evaluated an innovative technique to perform fluoroscopically directed thoracic intraforaminal nerve blocks that showed few complications and anatomically avoided transgression of structures in the posterior mediastinum.
-
To investigate whether an adaptive statistical iterative reconstruction (ASIR) algorithm improves the image quality at low-tube-voltage (80-kVp), high-tube-current (675-mA) multidetector abdominal computed tomography (CT) during the late hepatic arterial phase. ⋯ Compared with standard FBP reconstruction, an ASIR algorithm improves image quality and has the potential to decrease radiation dose at low-tube-voltage, high-tube-current multidetector abdominal CT during the late hepatic arterial phase.

Comparative Study
Accelerated two- and three-dimensional cine MR imaging of the heart by using a 32-channel coil.
To compare accelerated real-time two-dimensional (2D) and segmented three-dimensional (3D) cine steady-state free precession magnetic resonance (MR) imaging techniques by using a 32-channel coil with a conventional 2D cine imaging approach for imaging the heart and to evaluate any difference caused by free breathing and breath holding for real-time imaging. ⋯ Accelerated real-time 2D and segmented 3D cine techniques are comparable to the standard clinical protocol in assessment of left ventricular global and regional parameters in substantially shorter image times.
