Whole-body 18F-FDG PET/CT scan in a patient with Pancreatic Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; the palatine tonsils were symmetrical bilaterally, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings are clear.
Ground-glass nodules are present in the apical segment of the right upper lobe, the posterior basal segment of the left lower lobe, and the lateral basal segment of the right lower lobe, the largest being approximately 0.5 cm in long diameter, with a maximum CT value of -728 HU.
No abnormal FDG uptake was observed.
Calcification lesions are present in the right upper lobe, and a few linear lesions are present in both lungs.
FDG uptake is normal.
No pleural thickening is observed bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen.
FDG uptake is not increased.
Following radiofrequency ablation for liver metastases, the liver showed no significant abnormalities in morphology or size, with smooth liver margins and no widening of the liver fissures.
Multiple low-density nodules and masses were observed in the liver, the largest located in the right posterior lobe, with a long diameter of approximately 3.7 cm.
FDG uptake was absent, and no increase in FDG metabolism was observed after delayed contrast administration.
No significant FDG metabolism was observed in the remaining liver areas.
Several cystic lesions were present in the liver, the largest approximately 1.0 cm in diameter, with no abnormalities in FDG metabolism.
No significant widening of the main portal vein was observed, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in morphology or size, and the gallbladder wall showed no thickening; local FDG uptake was normal.
Following chemotherapy for pancreatic cancer, a soft tissue mass in the pancreatic body, approximately 4.0*2.4 cm in size, was observed, with increased FDG uptake (SUVmax=3.4).
The pancreatic tail was atrophied, and the pancreatic duct was dilated.
Peripancreatic lymph nodes were observed, the largest approximately 0.7 cm in short diameter, with increased FDG uptake (SUVmax=2.8).
The spleen showed no abnormalities in morphology, size, density, or FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
FDG uptake is normal, and no foci of increased FDG metabolism are seen after delayed contrast administration.
The renal pelvis, calyces, and ureters are not widened.
Bilateral adrenal glands show no obvious abnormalities on contrast administration.
The stomach is adequately filled, with no thickening of the gastric wall, and FDG uptake is normal.
Intestinal filling is unsatisfactory, with no local masses, and FDG uptake is normal.
The prostate is normal in size and uniform in density, with no abnormally increased FDG uptake.
The bladder is poorly filled, with no obvious positive stones.
A dense nodule of approximately 0.4 cm is seen in the right inguinal canal.
Multiple nodules and flocculent shadows are present in the mid-abdominal mesenteric region, with no abnormal FDG metabolism.
No ascites is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
The cortical margins of the 7th-10th posterior ribs on the left side are discontinuous with increased FDG uptake, SUVmax=3.1, and callus formation is visible.

Impression

1. a. After chemotherapy for pancreatic cancer, a soft tissue mass in the pancreatic body with increased FDG metabolism suggests continued tumor activity; peripancreatic lymph nodes show slightly increased FDG metabolism. It is recommended to compare these findings with pre-treatment imaging data and follow up. b. After radiofrequency ablation of liver metastases, multiple low-density nodules and masses were observed in the liver. The lesion in the right lobe showed loss of FDG uptake, but no significant increase in FDG metabolism, suggesting suppressed tumor activity after treatment. c. No space-occupying lesions were observed in either kidney, and FDG metabolism was normal. Enhanced MRI follow-up is recommended.

2. a. Ground-glass nodules in the apical segment of the right upper lobe, the posterior basal segment of the left lower lobe, and the lateral basal segment of the right lower lobe, with normal FDG metabolism, suggest inflammatory nodules or atypical adenomatous hyperplasia. Annual HRCT follow-up is recommended. b. Calcification in the right upper lobe, and a few post-inflammatory remnants in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Multiple liver cysts. Calcification in the right inguinal canal.

4. Degenerative changes in the spine, with L4/5 and L5/S1 intervertebral disc bulges. Post-fracture changes of the left 7th-10th ribs.

5. No obvious abnormalities were found on cranial scintigraphy.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
