General Electric Company (NYSE: GE)'s Healthcare segment is worth between $18.5 billion and $23.0 billion down 30% at the low end from the July value of $24.1 billion and $59.1 billion, according to my calculations.

GE Healthcare manufactures, sells and services medical equipment including equipment for magnetic resonance (MR), computed tomography (CT), positron emission tomography (PET) imaging, x-ray, patient monitoring, diagnostic cardiology, nuclear imaging, ultrasound, bone densitometry, anesthesiology and oxygen therapy, neonatal and critical care, and therapy.

GE Healthcare had a fair 2007. Its revenues rose 3% to $17.0 billion in 2007 as the effects of the weaker U.S. dollar ($0.5 billion) and higher volume ($0.4 billion) more than offset lower prices ($0.5 billion). Increased sales in the international diagnostic imaging, clinical systems and life sciences businesses were partially offset by price pressures on U.S. equipment sales and lower sales of surgical imaging equipment resulting from regulatory suspensions of equipment shipments.
