Dear Mr. Welton,
Below is PET/CT scan result. All looks favorable. Please let me know if you have additional questions.
Nathalie T. Nguyen, M.D.
** HISTORY **:
61-year-old man with a history of locally advanced squamous cell carcinoma (head and neck) status post chemoradiation completed October 2008.
** FINDINGS **:
DOSE: 14.3 mCi FDG (2-fluorine-18-fluoro-2-deoxy-D-glucose) ADM: IV
Comparison is made with 06/15/2008. The fasting blood glucose was 119 mg/dl.
Approximately one hour after injection of the radiopharmaceutical, the patient was imaged from the top of the brain to just beyond the inguinal region in 7 bed positions. For each bed position, a
four-minute emission scan was acquired. A CT scan of the same regions was performed. Please note that the CT portion of this study is a relatively low dose multi-slice scan without IV
contrast, intended only for attenuation correction and anatomic correlation of PET data. It is not an independent diagnostic study with respect to the clinical indications. Data were analyzed as a
whole body rendering using cinematic display and in the transaxial, sagittal, and coronal planes for slice-by-slice review.
Physiologic FDG distribution is seen within the brain. The two intensely hypermetabolic lesions in the left tonsil and the left superior jugular lymph node seen on the comparison PET scan are no longer identified. There is asymmetric low grade increased FDG activity about the left side of the neck, characteristic of chronic post radiation inflammatory changes rather than neoplastic disease. Distribution of FDG within the remainder of the head is unremarkable.
There are no suspicious hypermetabolic foci within the axillae, the thorax, abdomen, pelvis, with visualized portion of the musculoskeletal system. Normal FDG excretion is seen within the
** IMPRESSION **:
Foci of abnormal FDG activity are not identified that would suggest residual squamous cell carcinoma. Minor chronic post radiation inflammatory changes are suggested in the left side of
