[Assessment of cardiac function by magnetic resonance and multislice spiral computed tomography]. / Evaluation de la fonction cardiaque en imagerie par résonance magnétique et scanner hélicoïdal multicoupe.

Magnetic resonance imaging and multislice spiral computed tomography are ideal techniques for assessing cardiac function. The main objectives of this article are to describe the different aspects, global and regional systolic left ventricular function, diastolic left ventricular function and right ventricular function, and to introduce the agreed parameters for this evaluation.

[Myometrium diseases]. / Pathologie myométriale.

Leiomyoma and adenomyosis are the most frequent myometrial disorders, followed by cystic and vascular disorders. After an update on the anatomy, physiology and histology of the myometrium, the authors will describe the normal sonographic and MRI aspects of the uterus. The pathology of leiomyoma will be recalled, and the various forms of myoma encountered during Doppler US, hysterography, hysterosonography, MRI and computed tomography will be described. The therapeutic use of pelvic arteriography with arterial embolization will be discussed. Adenomyosis is the second most frequent essential myometrial disorder, and is often associated with leiomyoma. After giving a histopathologic definition, the authors will examine in some detail the diagnostic value and limitations of transabdominal, pelvic and endovaginal sonography and MRI. Intramyometrial cystic disorders (cystic adenomyosis, myoma with cystic degeneration and vestigial cysts) and vascular disorders (intramyometrial and parametrial vascular malformations) are rare, but a sound knowledge is required to optimize their management, which is based on surgery and interventional vascular techniques.
