[Cardiac effects of dermatomyositis. A case report].

The cardiac effects of dermatomyositis and polymyositis are found frequently at autopsy, even though the clinical manifestations are rare. We report the observation of a patient with dermatomyositis, in whom ventricular tachycardia, and dilated hypokinetic cardiomyopathy were in the foreground of the cardiac anomalies. This rhythm disturbance responds to treatment, as opposed to the associated dilated cardiomyopathy.

[Fetal thoracic MR imaging].

Ultrasonography is the method of choice for prenatal malformation screening, but it does not always provide sufficient informations to allow a correct diagnosis or an adequate abnormality evaluation. Fetal MRImaging (MRI) indications are increasing in order to complete sonographic findings. It has been initially used for evaluation of cerebral abnormalities, but it is more and more applied to other fetal areas.

[Magnetic resonance imaging applications in obstetrics].

Purpose: To review the main indications and results of magnetic resonance imaging in the pregnant women.

Material And Method: We reviewed MRI practice during the pregnancy based on our own experience in a prenatal diagnostic center and data in the literature. Rapid improvement in MRI technology has allowed more extensive use, giving a good contrast-to-noise ratio and multiplanar imaging.
