1. Treatment response of gastroesophageal junction region primary tumor,
hepatic metastases and upper retroperitoneal lymph node metastases identified on
PET/CT December 2017
2. Interval development of mediastinal lymph node metastases
PET/CT Skull Base to Mid Thigh
62 years old, male; Re-staging for gastric cancer
PET images were acquired from the skull base to the mid thighs following the
intravenous administration of 13.2 MCi of 18F-FDG. CT images were concurrently
obtained for attenuation correction. The CT examination is associated with an
estimated DLP of 498 mGy-cm. Blood glucose level at the time of scanning was 152
PT – PET-CT TUMOR IMAGE SKULL THIGH SUB 2017-12-30
PET images demonstrate elevated metabolic activity within mediastinal lymph
nodes, such as on axial image 78 left paratracheal lymph node with 6.8 SUV.
Borderline sized lymph node in the subcarinal space on axial image 87
demonstrates elevated metabolic activity up to 7.6 SUV. The previously noted
elevated metabolic activity within the gastroesophageal junction region, within
focal lesions of the liver and within upper retroperitoneal lymph nodes have
PET images demonstrate a generalized pattern of elevated metabolic activity
within abdominal wall musculature, nonspecific cause but unlikely to be related
to malignant disease.
CT attenuation correction images demonstrate a right jugular central venous
catheter. Additional benign findings included atherosclerotic calcifications,
colonic diverticula and perinephric infiltration.
