From: Blood perfusion in osteomyelitis studied with [15O]water PET in a juvenile porcine model
Example of scanning (pig no. 1). Top: CT image. Middle: Fusion of CT and [15O]water PET images (averaged over the 5 min scanning time). Bottom: Fusion of CT and parametric image of the K 1 parameter, i.e. the perfusion, with colour scale from 0 to 80 mL/min/100 cm3. In the images, a section is shown of the 3D VOIs drawn in the femoral medullar canal and in the thigh muscles. In this example, the positioning of the pig was very symmetric; in cases where pigs were slightly tilted to one side or had variation in how much the limbs were flexed, VOIs were drawn to correspond anatomically, not necessarily centred within the same slice
