Mechanical index

The mechanical index (MI) is an attempt to measure part of an ultrasound beam's bioeffects. The MI is found on most ultrasound display screens, along with the thermal index. Mechanical index is proportional to an ultrasound beam's peak negative pressure (or peak rarefaction pressure). It is al...

Thermal index

The thermal index (TI) is intended as a measure of an ultrasound beam's thermal bioeffects. It is often displayed on ultrasound screens (along with the mechanical index). Absorption of sound waves may cause heating in tissue. The thermal index depends on: a measure of time-averaged acoustic po...

Contrast media and breast feeding

Contrast media and breastfeeding is an area of imaging safety that has been investigated for both CT and MRI contrast agents. The current guidelines do not support the cessation of breastfeeding or any special precautions after CT and MRI intravenous contrast media administration. CT contrast a...
