[Applications of diffusion techniques in magnetic resonance imaging of musculoskeletal tumors].

Magnetic resonance imaging (MRI) is the technique of choice in the diagnosis, staging, and follow-up of musculoskeletal tumors. Diffusion imaging is a new functional MRI technique that provides information that is complementary to that obtained in conventional MRI sequences. Diffusion imaging has proven useful in different clinical situations like the characterization of disease involving the bone marrow (bone metastases, benign fractures, or hematological disease), the evaluation of tumors of the bones and soft tissues, and the monitoring of the response to treatment in patients with tumors.

[Chest trauma: spectrum of lesions].

Blunt chest trauma typically occurs as part of polytrauma, usually secondary to motor vehicle accidents, sports related injuries or defenestration in Western Europe. Each chest compartment may be responsible for immediate and/or delayed complications, thus requiring a dedicated systematic and comprehensive analysis. The use of image post-processing is mandatory in order to not overlook a potentially severe injury.

Spontaneous regression of intracranial arteriovenous malformations. A report of two cases.

Spontaneous and complete regression of cerebral arteriovenous malformations has rarely been reported in the literature. We describe two new cases with a literature review.
