Co-registered maximum intensity projection SPECT and CT images at 40-min post-injection from representative animals from the low (0.8 mL) volume (a), low volume plus percussive wrap (b), high (2.4 mL) volume (c), or high volume plus percussive wrap (d) treatment groups. The ^99mTc-DTPA tracer incorporated into the dosing solution appears as bright areas within the spinal and cranial areas. SPECT images are scaled from 0 to 1% injected dose/g indicated by the color scale bar. Bright artefacts seen on the images are pulse oximeter sensors placed on the ear
