Kidney surveillance in the spotlight: contrast-induced acute kidney injury illuminated [PDF]

open access: yes, 2018
Acute kidney injury comprises a heterogeneous group of conditions characterized by a sudden decrease in renal function over hours to days. Contrast-induced acute kidney injury (CI-AKI) is caused by radiographic contrast agents used in diagnostic imaging.

Diethyl 3,3′-[(4-fluorophenyl)methylidene]bis(1H-indole-2-carboxylate)

open access: yesIUCrData, 2019
In the title compound, C29H25FN2O4, the mean planes of the indole ring systems (r.m.s. deviations = 0.0107 and 0.0158 Å) are approximately perpendicular to each other, subtending a dihedral angle of 87.43 (16)°. The 4-fluorophenyl ring is twisted by 77.6

Stable Thermally-Modulated Nanodroplet Ultrasound Contrast Agents

open access: yesNanomaterials, 2021
Liquid perfluorocarbon-based nanodroplets are stable enough to be used in extravascular imaging, but provide limited contrast enhancement due to their small size, incompressible core, and small acoustic impedance mismatch with biological fluids.

Functionalized multiwalled carbon nanotubes as ultrasound contrast agents [PDF]

open access: yes, 2012
Ultrasonography is a fundamental diagnostic imaging tool in everyday clinical practice. Here, we are unique in describing the use of functionalized multiwalled carbon nanotubes (MWCNTs) as hyperechogenic material, suggesting their potential application ...
