pertechnetate rather than a right-to-left shunt. 20 – Free Tc-99m pertechnetate is also visualized in thyroid gland, salivary glands and gastric mucosa ○ Use reduced MAA particle count (100,000-200,000) in case of suspected shunt, pulmonary hypertension, pregnancy or pediatric patient ○ Can quantitate the degree of shunt if desired – Right-to-left shunt % = (total body counts - lung counts)/(total body counts x 100) DIAGNOSTIC CHECKLIST • Always scrutinize VQ scans for unexpected incidental

injection. The patient’s head can be restrained to avoid motion. F-18 FDG is a PET tracer that measures glucose metabolism in the brain and has largely surpassed SPECT for diagnosing an etiology for dementia. F-18 FDG requires patient preparation of fasting for 4-6 hours and no IV fluids that contain dextrose. Furthermore, patients need to be in a quiet, dark room with little noise in order to limit regional brain activation. When evaluating patterns of dementia on F-18 FDG PET/CT or SPECT, it is

metaphyses of long & tubular bones – Parallel striations to long axis of bones – Iliac bones may show fan-shaped striations – No significant uptake on bone scan Chondroblastoma – Well-defined, osteolytic lesion with thin sclerotic rim located in epiphysis or apophyses of long bone – Femur, tibia, humerus, patella, and tarsal bones – Skeletally immature patient – Bone scan shows focal increased uptake Osteochondroma – Most common benign bone tumor – Most commonly in long bones of upper & lower

(Fe/iron surrogate), may be helpful in chronic osteomyelitis – When compared with bone scan, Ga-67 uptake should be greater than bone scan uptake or show uptake of different size (larger or smaller) – Preferred over In-111 WBC for spinal discitis/osteomyelitis due to potential false (-) result ○ SPECT and SPECT/CT adds specificity to location of abnormal activity • Correlative imaging features ○ Plain film: Limited sensitivity and specificity – Normal initially; recognition may take 2-3 weeks
