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: A few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no obvious abnormalities.
The mucosa of the bilateral maxillary and ethmoid sinuses was thickened, but the sinus walls were intact.
The nasal septum was deviated.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Multiple solid nodules were observed in both lungs, with a long diameter of approximately 0.2-0.4 cm and clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
No esophageal dilation was observed, and no significant thickening or mass was seen in the esophageal wall; FDG uptake was not increased.
The liver has an irregular outline.
Two slightly low-density lesions are seen in the left lateral lobe of the liver, the larger one measuring approximately 1.5 cm in long diameter, with increased FDG metabolism (SUVmax = 12.3).
Multiple cystic lesions are seen within the liver, measuring approximately 4.6 4.3 cm, with absent FDG uptake.
No significant widening of the main portal vein is observed, and no dilation of intrahepatic or extrahepatic bile ducts is seen.
The gallbladder appears normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
A dense mass is seen in the body of the pancreas, with indistinct boundaries from adjacent vessels, a CT value of approximately 30 HU, measuring approximately 3.6 2.5 cm, with increased FDG metabolism (SUVmax = 13.2).
The surrounding fat space is blurred, accompanied by several slightly enlarged lymph nodes, the largest measuring approximately 0.5 cm in short diameter, with increased FDG metabolism (SUVmax = 3.6).
The tail of the pancreas is atrophied.
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, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
Stomach distension was poor, with no obvious thickening of the stomach wall, and FDG uptake was not significantly abnormal.
Continuous FDG metabolism in the sigmoid colon and rectum was increased, SUVmax=5.3.
The prostate was normal in shape and size, with uniform density, and no abnormal FDG metabolism was observed.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious effusion was 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.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass in the body of the pancreas, with indistinct borders with adjacent vessels and elevated FDG metabolism, suggestive of pancreatic malignancy. Pathological examination is required for confirmation. b. Blurred fat spaces surrounding the lesion, accompanied by several slightly enlarged lymph nodes with elevated FDG metabolism, suggesting a high probability of metastasis. c. Two nodules metastasized to the left lateral lobe of the liver. Multiple hepatic cysts.

2. Multiple small, solid, chronic inflammatory nodules in both lungs are highly probable; CT scan is recommended. A small amount of chronic inflammation and old lesions in both lungs. Calcification of some arterial walls.

3. Continuous elevated FDG metabolism in the sigmoid colon and rectum, suggestive of inflammatory or physiological uptake; colonoscopy is recommended.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

5. A few ischemic foci in the deep cerebral regions bilaterally; age-related brain. Minor chronic inflammation of the bilateral maxillary and ethmoid sinuses. Nasal septum deviation.

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.
