Indocyanine green (ICG) is a cyanine dye used in medical diagnostics. It is used for determining cardiac output, hepatic function, and liver blood flow, and for ophthalmic angiography. It has a peak spectral absorption at about 800 nm. These infrared frequencies penetrate retinal layers, allowing ICG angiography to image deeper patterns of circulation than fluorescein angiography.
Rate of interest R = I / PT, where I is the interest, P is the principal amount, T is the interest period, and R is the rate of interest. Rate of interest can be annual, half yearly, or quarterly according to the deal made.
Interest rates refers to the rate set by a country's Central bank and is the % of money commercial banks are allowed to hold or lend at one time. If Interest rates are down then a commercial bank can lend more money out at one time, and vise versa for high interest rates.
