Introducing Online Continuing Education in Radiology for General Practitioners.

The aim of this study was to determine whether e-learning as a new teaching methodology was acceptable for general practitioners in continuous education courses of radiology. Generally, these courses are face-to-face with the corresponding time and place limitations. To overcome these limitations, we transformed one of these courses to an online one evaluating its acceptance.

Prevalence and incidence of Q-wave unrecognized myocardial infarction in general population: Diagnostic value of the electrocardiogram. The REGICOR study.

Background: Diagnosis of unrecognized myocardial infarction (UMI) remains an open question in epidemiological and clinical studies, inhibiting effective secondary prevention of myocardial infarction. We aimed to determine the prevalence and incidence of Q-wave UMI in asymptomatic individuals aged 35 to 74years, and to ascertain the positive predictive value (PPV) of asymptomatic Q-wave to diagnose UMI.

Methods: Two population-based cross-sectional studies were conducted, in 2000 (with 10-year follow-up) and in 2005.

A diagnostic approach to the mediastinal masses.

Background: Multiple different types of mediastinal masses may be encountered on imaging techniques in symptomatic or asymptomatic patients. The location and composition of these lesions are critical to narrowing the differential diagnosis.

Methods: Radiological compartmentalisation of the mediastinum helps in focusing the diagnosis of masses on the basis of their site.

Multislice CT in congenital heart disease: Partial anomalous pulmonary venous connection.

Computed Tomography (CT) is increasingly becoming an imaging technique for congenital heart diseases, particularly for the diagnosis of partially anomalous pulmonary venous connections. When echocardiography cannot provide the diagnosis, multislice CT offers some advantages in comparison with RMN and angiography.

Second malignancies in pediatric patients: imaging findings and differential diagnosis.

Therapeutic advances in the treatment of pediatric neoplasms have improved the prognosis but have also increased the risk of developing rare second malignant neoplasms (SMNs). Primary neoplasms that are often associated with SMNs include lymphoma, retinoblastoma, medulloblastoma, neuroblastoma, and leukemia. The most common SMNs are central nervous system (CNS) tumors, sarcomas, thyroid and parotid gland carcinomas, and leukemia, particularly acute myeloblastic leukemia.
