Ultrasound scanning as a screening technique for hydatidosis in developing countries.

This study presents new evidence as to the usefulness of ultrasound scanning in field conditions, to screen out hydatidosis in endemic areas, and to compare its detection capability with serological methods. It also intends to demonstrate that for an efficient rural ultrasound screening, neither an experienced ultra sonographer nor expensive and sophisticated equipment is necessary, it can be done by suitably trained personnel (eg, nurse, public health worker), using basic equipment, without public health installations or electricity, thus making it a feasible, simple, fast, and cheap screening method for hydatidosis.
