Perfusionstest
Perfusionstest, or perfusion testing, refers to a group of diagnostic procedures that measure the passage of blood through tissue or organs. The goal is to assess tissue perfusion, evaluate blood flow, and determine tissue viability or function. Perfusion tests can be noninvasive imaging studies, involve contrast or radioactive tracers, or use invasive techniques in specialized centers.
Common applications include brain, heart, and lungs, though perfusion assessment can be extended to other organs.
In cardiology, myocardial perfusion imaging (MPI) with SPECT or PET evaluates blood flow to the heart muscle
In pulmonology, ventilation-perfusion (V/Q) scintigraphy combines ventilation assessment with perfusion imaging to identify pulmonary embolism or
Non-imaging methods, such as Doppler ultrasound, can provide indirect information about tissue and organ perfusion by
