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 scan showed: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; midline shift was not observed.
Both eyes were symmetrical, with no obvious abnormalities.
The maxillary sinus mucosa was thickened bilaterally, but the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened; FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear; FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; multiple solid nodules are present in both lungs, the largest being approximately 0.5 cm in diameter; FDG uptake is normal.
Lung translucency is increased bilaterally, with multiple air-filled cavities and a few scattered linear lesions; FDG uptake is normal.
No pleural thickening is seen bilaterally; there is no pleural effusion or pneumothorax.
Lymph nodes are visualized in the bilateral hilar, pretracheal, para-aortic arch, aortopulmonary window, and subcarinal lymph nodes; the largest has a short diameter of approximately 0.6 cm; FDG uptake is increased, SUVmax = 3.3.
Cardiac silhouette is normal.
Some arterial walls are calcified (including coronary arteries).
A right clavicular port has been inserted.
No esophageal dilation, no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
No obvious abnormalities in liver morphology and size, smooth liver margins, no widening of the liver fissure, a cystic lesion in the left inner lobe of the liver, approximately 1.6 cm in diameter, with no abnormal FDG uptake.
No obvious space-occupying lesions were observed in the remaining liver area, no abnormal FDG uptake was observed, no obvious widening of the main portal vein, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder is poorly visualized.
Following chemotherapy for pancreatic cancer, a pelvic drainage tube was inserted.
An irregular soft tissue density shadow was observed in the pancreatic body, with indistinct borders and calcifications measuring approximately 2.9*1.9 cm.
FDG uptake was slightly increased, SUVmax=2.3, with indistinct demarcation from the adjacent gastric wall.
No obvious dilation of the pancreatic duct was observed, and the pancreatic tail was atrophied.
Peripancreatic and retroperitoneal small lymph nodes were observed, the largest with a short diameter of approximately 0.6 cm; FDG metabolism was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
The left adrenal gland was enlarged; FDG metabolism was normal.
The right adrenal gland showed no obvious abnormalities on contrast.
Stomach distension was poor; the walls of the cardia, part of the gastric body, and antrum were slightly thickened; FDG uptake was increased, SUVmax = 4.5.
Intestinal distension was unsatisfactory; FDG uptake was increased in some parts of the intestine, SUVmax = 7.2.
The prostate was normal in size and uniform in density; FDG uptake was not abnormally increased.
Bladder distension was poor; no obvious positive stones were observed.
Decreased bone density throughout the body, normal spinal alignment, osteophyte formation at the margins of some vertebral bodies, and L5/S1 disc bulge.
No abnormalities were observed in systemic bone marrow FDG metabolism.

Impression

1. After chemotherapy for pancreatic cancer, irregular soft tissue density shadows were observed in the pancreatic body, with slightly increased FDG metabolism; small lymph nodes around the pancreas and in the retroperitoneum showed no abnormalities in FDG metabolism. This suggests that most tumor activity is suppressed after treatment; comparison with previous imaging data and follow-up are recommended.

2. Chronic inflammatory nodules in both lungs; CT follow-up is recommended. Bilateral emphysema. A few post-inflammatory remnants in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Calcification of some arterial walls (including coronary arteries). A port-a-cath has been placed in the right clavicular region.

3. Cyst in the left lobe of the liver; no other obvious space-occupying lesions were seen in the liver, and FDG metabolism was normal. MRI is recommended.

4. Left adrenal hyperplasia.

5. Chronic inflammatory changes in part of the gastric wall and intestinal tract; endoscopic follow-up is recommended.

6. Osteoporosis, degenerative changes in the spine, L5/S1 disc bulge.

7. Age-related brain abnormalities, deep lacunar infarcts; please include MRI.

8. Bilateral chronic maxillary sinusitis.

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.
