<unk> ning typically uses a gamma camera to obtain SPECT images, with an injection followed by an initial<unk>  after 5 minutes, and a second<unk>  after 3 hours. Images are often scored using the "Perugini system" whereby: * Grade 0 – no cardiac uptake and normal bone uptake * Grade 1 – cardiac uptake which is less intense than the bone signal * Grade 2 – cardiac uptake with intensity similar or greater than bone signal * Grade 3 – cardiac uptake with much attenuated or absent bone signal
