Although photoacoustic computed tomography (PACT) operates with high spatial
resolution in biological tissues deeper than other optical modalities, light
scattering is a limiting factor. The use of longer near infrared wavelengths
reduces scattering. Recently, the rational design of a stable phosphorus
phthalocyanine (P-Pc) with a long wavelength absorption band beyond 1000 nm has
been reported. Here, we show that when dissolved in liquid surfactants, P-Pc can
give rise to formulations with absorbance of greater than 1000 (calculated for a
1 cm path length) at wavelengths beyond 1000 nm. Using the broadly accessible
Nd:YAG pulse laser emission output of 1064 nm, P-Pc could be imaged through 11.6
cm of chicken breast with PACT. P-Pc accumulated passively in tumors following
intravenous injection in mice as observed by PACT. Following oral administration,
P-Pc passed through the intestine harmlessly, and PACT could be used to
non-invasively observe intestine function. When the contrast agent placed under
the arm of a healthy adult human, a PACT transducer on the top of the arm could
readily detect P-Pc through the entire 5 cm limb. Thus, the approach of using
contrast media with extreme absorption at 1064 nm readily enables high quality
optical imaging in vitro and in vivo in humans at exceptional depths.
