Fundamental Concepts and ExamplesIn this first chapter, we present some basic definitions and concepts which will be of constant use in this course. We also discuss the main difficulties of the theory and briefly indicate the main results to be established in the forthcoming chapters.OREX 发表于 2025-3-22 05:30:38

Diagnostic ultrasound is non-invasive and harmless—important advantages in the woman with an unsuspected pregnancy. With ultrasonography (USG), the presence of an Intrauterine contraceptive device (IUD) in the uterus can be assessed and its position demonstrated (Cochrane and Thomas, 1972; Iannirub性学院 发表于 2025-3-22 14:51:46

The papers evaluate biologic interactions be tween intrauterine contraceptive devices and the host, examine the risks associated with the use of these devices and describe aspects of technical progress in the field.
