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:Patchy low-density shadows were visible in the deep brain regions bilaterally, with no abnormalities in FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal, and there was no midline shift.
No significant abnormalities were observed in the skull bone, and no increased FDG uptake was seen.
The morphology and contour of both eyeballs were normal, the retrobulbar structures were clear, the optic nerves were symmetrical bilaterally, and no abnormal FDG uptake was observed.
Thickening of the left maxillary sinus mucosa was observed, but the sinus wall was intact.
The nasal septum was slightly deviated, and the inferior turbinates were thickened bilaterally, with no abnormal FDG uptake.
No abnormal density shadows were seen in the nasopharynx and oropharynx, and FDG metabolism was normal.
The morphology and structure of the laryngopharynx were normal.
The size, shape, and density of the bilateral submandibular and parotid glands are normal, and FDG uptake is physiological.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No significantly enlarged lymph nodes are seen in the bilateral neck, submandibular, and submental regions, and FDG uptake is normal.
Scattered patchy, linear, and unevenly dense shadows and punctate foci are seen in both lungs, and FDG uptake is normal.
The pleura is thickened bilaterally.
The trachea is midline, and the trachea and segmental bronchi are patent, with no significant thickening of the tracheal walls or significant stenosis of the lumen.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions, and FDG uptake is not significantly increased.
The heart is within the normal size range, and myocardial FDG uptake is normal.
The pericardium is not thickened, and there is no effusion within the pericardium; the density of the cardiac chambers is lower than that of the myocardium.
Post-hepatocellular carcinoma surgery, the remaining liver has an irregular shape, widened hepatic fissures, and uneven liver density.
No abnormal FDG uptake was observed.
Small, roundish, cystic low-density shadows are also visible within the liver parenchyma, the largest being approximately 0.3 cm in diameter, with decreased FDG uptake.
Absent after cholecystectomy, local FDG uptake was normal.
The pancreas has a clear outline, normal shape and size, no obvious abnormal density shadows, no widening of the pancreatic duct, and no abnormal FDG uptake.
The spleen is slightly enlarged, with no abnormal density or FDG uptake.
Roundish, cystic low-density shadows are visible in both kidneys, the largest being approximately 1.0 cm in diameter, with decreased FDG uptake.
No abnormal density shadows are seen in the renal pelvis, calyces, and ureters bilaterally, and no obvious abnormalities in FDG uptake are observed.
The bilateral adrenal glands are slightly enlarged, with mildly increased FDG uptake, SUVmax=3.2.
Irregular thickening of the duodenal bulb wall with a mass formation, measuring approximately 5.4*5.9cm, with increased FDG uptake (SUVmax=5.2), and indistinct demarcation from the gastric antrum and adjacent liver.
A cystic shadow protrudes from the descending duodenum, with a long axis of approximately 1.2cm.
Continuous FDG uptake is observed in the remaining intestinal portion (SUVmax=7.4).
No esophageal dilation was observed, and no increased FDG uptake was observed in the local esophageal wall.
A significant amount of residual contents remained in the stomach, with partial gastric wall thickening accompanied by increased FDG uptake (SUVmax=3.3).
No significantly enlarged lymph nodes were observed in the abdominopelvic cavity, and FDG uptake was normal.
No intraperitoneal fluid was observed.
The prostate gland is full and protrudes into the bladder, with scattered punctate and patchy calcifications visible within; FDG uptake is essentially normal. "Post-bladder cancer surgery," bladder filling is adequate, and no obvious mass was observed locally.
A low-density shadow with coarse trabecular bone was visible in the T10 vertebral body; FDG uptake was not significantly abnormal.
Strip-like areas of increased FDG uptake were visible in the spinal canal at the T11-T12 vertebral body level (SUVmax = 2.6).
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and facet joints.
Mild posterior displacement of the L2 vertebral body was observed, along with multiple intervertebral disc bulges and pneumothorax.
Focal FDG uptake was present bilaterally around the shoulders (SUVmax = 8.2), more pronounced on the left side.

Impression

1. a. "Post-hepatocellular carcinoma surgery changes": No obvious space-occupying lesions were seen in the remaining liver; FDG metabolism was normal. Follow-up MRI is recommended. Liver cirrhosis, slightly enlarged spleen. b. Irregular thickening of the duodenal bulb wall with mass formation; increased FDG metabolism, consistent with metastatic tumor presentation based on medical history.

2. Scattered chronic inflammation and remnants in both lungs. Pleural thickening bilaterally. Anemia.

3. Small hepatic cysts. Post-cholecystectomy changes.

4. Bilateral renal cysts. Bilateral adrenal hyperplasia. Prostatic hyperplasia with calcification. "Post-bladder cancer surgery" changes; no signs of tumor recurrence were observed.

5. Chronic gastritis; continuous increased FDG uptake in the remaining intestinal tract, suggestive of chronic enteritis or physiological uptake. Duodenal diverticulum. 6.a. The previously observed increased FDG uptake lesions on the left side of the L5 vertebral body and the left erector spinae muscle were not visualized. Increased FDG uptake strips within the spinal canal at the T11-T12 vertebral body level are similar to the previous findings, suggesting a physiological change. b. T10 vertebral hemangioma. Degenerative changes in the spine. Mild posterior slippage of the L2 vertebral body. Multiple intervertebral disc bulges with pneumoconiosis and degeneration. Bilateral frozen shoulder.

6. Bilateral deep cerebral ischemic lesions, age-related brain changes. Chronic inflammation of the left maxillary sinus.

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.
