Whole-body 18F-FDG PET/CT scan in a patient with Liver 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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened, and 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, with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The 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.
The lung markings are clear bilaterally.
Small solid nodules are present in the posterior basal segment of the lower lobes of both lungs; the right nodule is larger, with clear borders, and approximately 0.4 cm in diameter.
FDG uptake is normal.
A few linear lesions are present in both lungs; FDG uptake is normal.
No pleural thickening or pleural effusion/pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
The cardiac chamber density is slightly lower than that of the myocardium.
The esophagus is not dilated; the esophageal wall is not significantly thickened or lumped; FDG uptake is normal.
The liver margins are not smooth, the proportions of the left and right lobes are disproportionate, the hepatic fissure is slightly widened, and multiple nodules and masses of slightly low density shadows are present in the liver with indistinct borders.
FDG uptake is increased, SUVmax=5.2, with the most significant increase located in the right anterior lobe of the liver.
Focal FDG uptake in the portal vein is increased, SUVmax=4.1.
The intrahepatic bile ducts are slightly widened, and the portal vein is widened, with focal FDG uptake also visible, SUVmax=4.5.
Multiple varices are present in the lower esophagus and gastric fundus.
The hilar and retroperitoneal lymph nodes are visible, the largest being approximately 0.9 cm in diameter, with slightly increased FDG uptake, SUVmax=2.1.
Abdominal and pelvic effusion is present.
The gallbladder is normal in shape and size, with thickened gallbladder walls and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
Spleen slightly enlarged, density and FDG uptake normal.
Both kidneys normal in shape and size, several punctate dense shadows in both renal calyces, no widening of renal pelvis, calyces, or ureters, no significant abnormality in FDG uptake.
Left adrenal gland thickened, FDG metabolism normal.
Right adrenal gland no significant abnormality on contrast.
Poor gastric filling, slight thickening of the cardia, part of the gastric body, and antrum walls, increased FDG uptake, SUVmax=3.4.
Intestinal filling unsatisfactory, increased FDG metabolism in part of the intestinal tract, SUVmax=5.7.
Prostate normal in size, punctate dense shadows seen inside, no abnormally increased FDG uptake.
Bladder poorly filled, no obvious positive stones seen inside.
Spinal alignment normal, mild osteophyte formation at the margins of some vertebral bodies.
Increased density at both sacroiliac joint surfaces, with no abnormal FDG uptake observed.
No abnormalities were found in systemic bone marrow FDG metabolism.

Impression

1. a. Multiple space-occupying lesions in the liver with increased FDG metabolism, highly suggestive of primary liver cancer with portal vein tumor thrombus formation. Please combine clinical findings with enhanced MRI for comprehensive analysis. b. Changes in liver cirrhosis, slightly enlarged spleen, portal hypertension with collateral circulation formation; possible reactive hyperplasia of the hilar and retroperitoneal lymph nodes, follow-up recommended; ascites and pelvic effusion.

2. Small solid nodules in the lower lobes of both lungs, FDG metabolism normal, suggestive of inflammatory nodules, CT follow-up recommended to rule out other possibilities. A few post-inflammatory lesions in both lungs. Mild anemia.

3. Chronic cholecystitis. Left adrenal hyperplasia. Bilateral renal calculi. Prostatic calcification.

4. Possible chronic inflammatory changes in part of the gastric wall and intestinal tract, please combine endoscopic follow-up.

5. Mild vertebral osteophyte formation. Bilateral sacroiliac joint condensing osteitis.

6. Cranial scintigraphy showed no obvious abnormalities.

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.
