Computed Tomography Angiography in Peripheral Arterial Disease: Comparison of Three Image Acquisition Techniques to Optimize Vascular Enhancement-Randomized Controlled Trial.

To prospectively compare three image acquisition techniques in lower extremity CT angiography: the "standard" anterograde technique (SA), the adaptive anterograde technique (AA), and the retrograde acquisition technique (RA). Sixty consecutive patients were prospectively enrolled and randomized into three acquisition groups: 20 patients were evaluated with SA, 20 with AA as described by Qanadli et al., and 20 with caudocranial acquisition from the feet to the abdominal aorta (RA).

Survey of management of first-ever seizures in a hospital based community.

Background: Epidemiological studies focusing on first-ever seizures have been carried out mainly on community based populations. However, since hospital populations may display varying clinical features, we prospectively analysed patients with first-ever seizure in a hospital based community to evaluate prognosis and the role of complementary investigations in the decision to administer antiepileptic drugs (AED).

Methods: Over one year, we recruited 177 consecutive adult patients with a first seizure acutely evaluated in our hospital.
