Subcontractor Agreement Basics. Whether you're a subcontractor or just hiring one, a subcontractor agreement helps protect both your interests.

Other important clauses include insurance, default, change orders, and indemnification.

Ultrasound may not always detect RS, but can show a poorly defined hypoechoic area, or an irregular hypoechoic mass with ill-defined, spiculated margins and varying degrees of posterior shadowing. The mass parenchyma was homogenic and hypoechoic and was determined to have an increased blood flow by Doppler assessment.
