    9. 9. <ul><li>HISTORY A 47-year-old male with recurrent colorectal cancer. Patient had a resection of part of his colon 8 months prior to his initial PET scan. </li></ul><ul><li>ORIGINAL DIAGNOSIS CT scans at both 5 and 8 months post-resection were reported as normal. The patient still complained of abdominal pain, and at the patient’s request, a PET scan was ordered. </li></ul><ul><li>PET FINDINGS The whole-body FDG PET scan at 8 months post-resection revealed extensive lesions in both the liver and bowel. </li></ul><ul><li>CHANGE IN TREATMENT Based on the findings of the PET scan, the patient underwent chemotherapy and returned five months after the initial PET scan for a follow-up PET scan. The follow-up scan showed remission in all known tumor sites. </li></ul>PRE-THERAPY POST-THERAPY Colorectal Cancer Courtesy of University of Kansas Medical Center • Kansas City, Kansas

There is increased uptake in a retroperitoneal node at the T11-12 level. In addition, focus of abnormal uptake is present superior to the left kidney. Another large focus of abnormal activity is present between the anterior pole of the left kidney in the left lobe of the liver. Small focus of abnormal activity is present just posterior to the superior left lobe of the liver. </li></ul><ul><li>CHANGE IN TREATMENT </li></ul><ul><li>PET enabled the physician to diagnosis the disease and begin treatment immediately. </li></ul>Non-Hodgkin‘s Lymphoma Courtesy of the University of Colorado, Gloria Cook PET Center, Denver, Colorado

    12. 12. <ul><li>HISTORY </li></ul><ul><li>A 3-year-old male epilepsy </li></ul><ul><li>ORIGINAL DIAGNOSIS Patient suffered from intractable drop seizures since the age of 18 months. MRI showed no abnormalities. Interictal scalp EEG demonstrated epileptiform activity emanating from the right parietal region . </li></ul><ul><li>PET FINDINGS </li></ul><ul><li>The PET abnormality guided the subdural grid placement with very good correlation. </li></ul><ul><li>CHANGE IN TREATMENT </li></ul><ul><li>The patient was submitted to surgery and is seizure-free . </li></ul><ul><li>Courtesy of Children’s Hospital, Detroit, Michigan </li></ul>Epilepsy
    13. 13. <ul><li>HISTORY </li></ul><ul><li>An 86-year-old male with history of suspected Alzheimer’s . </li></ul><ul><li>PET FINDINGS PET shows hypo-metabolism temporoparietal and reduced glucose uptake in cranial portion of both frontal lobes consistent with Alzheimer’s disease </li></ul><ul><li>CHANGE IN TREATMENT Conventional treatment would be watchful waiting and annual imaging, clinical, and behavior tests for up to five years before diagnosis is confirmed. </li></ul><ul><li>Institut für Medizin Forschungszentrum Jülich, Germany </li></ul>Alzheimer’s Disease

After PET, coronary artery bypass graft was performed resulting in improved cardiac function. Patient had significant improvement in quality of life. </li></ul>Myocardial Viability Courtesy of Rush-Presbyterian-St. Luke's Medical Center, Chicago, Illinois SHORT AXIS H LONG AXIS V LONG AXIS
