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, 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 and without significant abnormalities.
Thickening of the mucosa of the bilateral maxillary and ethmoid sinuses was observed, but the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The bilateral 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 bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed 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.
Several solid micronodules were observed in both lungs, with a long diameter of approximately 0.2-0.3 cm and clear borders; FDG metabolism was normal.
A few punctate foci, calcifications, and linear foci were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally; a small amount of pleural effusion was observed in the left pleural cavity.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The density of the cardiac chambers was lower than that of the myocardium.
No esophageal dilatation was observed; no significant thickening or mass was seen in the esophageal wall, and FDG uptake was not increased.
The liver has an irregular outline, disproportionate lobes, widened fissures, and wavy edges.
Multiple masses and nodules of varying sizes are seen within the liver, mostly located in the left lobe.
FDG metabolism is increased, with SUVmax = 6.5.
The portal vein is thickened.
Punctate calcifications are seen in the right lobe of the liver.
The greater omentum and mesentery show flocculent thickening, but FDG metabolism is normal.
Tortuous blood vessels are seen near the gastric fundus and splenic hilum.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen is enlarged, but FDG uptake is normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly filled, with slight thickening of the walls in parts of the gastric body and antrum, and slightly increased FDG uptake (SUVmax = 2.3).
The intestines are poorly filled, with continuous FDG metabolism increased in parts of the colon and rectum (SUVmax = 4.5).
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is seen.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
There is fluid accumulation in the abdominal and pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
No abnormalities were observed in systemic bone marrow FDG metabolism.

Impression

1. a. Multiple lesions in the liver, increased FDG metabolism, highly suggestive of liver cancer; please correlate with clinicopathology. b. Possible portal vein tumor thrombus; cirrhosis; splenomegaly; portal hypertension. Liver calcifications. Abdominal and pelvic effusions. Flocculent thickening of the greater omentum and mesentery, FDG metabolism normal; please follow up.

2. Several small chronic inflammatory nodules (solid) in both lungs. A small amount of chronic inflammation and old lesions in both lungs. Small amount of pleural effusion on the left side. Anemia.

3. Chronic gastritis; increased FDG metabolism in some intestinal segments, considered inflammatory or physiological uptake. Follow-up gastroscopy and colonoscopy are recommended.

4. Degenerative changes in the spine. L4/5, L5/S1 intervertebral disc bulge.

5. No abnormalities found on cranial scintigraphy. Chronic inflammation of both maxillary sinuses and both ethmoid sinuses.

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.
