Scanning techniques in obstetrics and gynecology

Using the appropriate scanning techniques and knowing the advantages and disadvantages of ultrasound equipment, the clinically useful pictures that enable better care of the obstetric and gynecologic patient can be generated. The extra advantage of applying the best possible scanning technique may enable the clinician or the imaging specialist to arrive at the correct diagnosis, despite problems created by anatomic circumstances, such as body habitus. The widespread use of ultrasound in general and transvaginal sonography in particular substantially has changed obstetric and gynecologic practice. High frequency transducer probes enable the creation of a crisp detailed picture that facilitates a more accurate and faster diagnostic procedure. Transvaginal sonography should be considered the first choice laboratory tool in the diagnosis of an increasing number of obstetric and gynecologic entities.
