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 images showed: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Bilateral eyeballs were symmetrical with no obvious abnormalities.
A cystic shadow was seen in the right maxillary sinus; the mucosa of the remaining paranasal sinuses showed no thickening, and the sinus walls were intact.
The nasal septum was deviated; the nasopharyngeal wall was not thickened; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The bilateral parotid and submandibular glands were normal in morphology and density, with physiological FDG uptake.
The thyroid gland was normal in morphology and size, with slightly uneven density; multiple nodules were present in both lobes, the largest being approximately 0.9 cm in diameter; FDG uptake was normal.
No significantly enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings are clear.
A small solid nodule, approximately 0.3 cm in diameter, is present in the apical segment of the right upper lobe; no abnormal FDG uptake was observed.
Scattered linear lesions are present in both lungs; no abnormal FDG uptake was observed.
No pleural thickening or pleural effusion/pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were observed in the hilum or mediastinum bilaterally.
The cardiac silhouette is normal; the cardiac chamber density is slightly lower than that of the myocardium.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus is not dilated; no significant thickening or mass is observed in the esophageal wall; no increased FDG uptake was observed.
The liver is normal in shape and size; the liver margins are smooth; the hepatic fissure is not widened; diffuse low-density nodules and masses are present in the liver, some of which have coalesced into clumps; increased FDG uptake is observed (SUVmax = 15.5).
A cystic lesion, approximately 2.3 cm in long diameter, is present in the right posterior lobe of the liver; FDG uptake is absent.
Multiple lymph nodes were observed in the porta hepatis and retroperitoneum, the largest measuring approximately 1.8 cm in short diameter, with increased FDG uptake (SUVmax = 10.1).
The gallbladder was enlarged, containing a high-density lesion measuring approximately 6.5 x 4.6 cm.
The gallbladder wall showed irregular thickening with patchy areas of increased FDG uptake (SUVmax = 5.6).
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
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.
The left adrenal gland was slightly thickened, while the right adrenal gland showed no significant abnormalities on contrast.
The stomach was adequately distended, with slight thickening of the gastric wall in the antrum and mildly increased FDG uptake (SUVmax = 1.9).
The intestines were not adequately distended, with no local masses and no abnormal FDG uptake.
The prostate is enlarged with calcifications, and FDG metabolism is uneven.
The bladder is poorly filled, but no obvious positive stones are visible.
Multiple bone destructions are observed in the sternum, right clavicle, multiple ribs, multiple vertebral bodies and appendages of the spine, sacrum, right ilium, and left pubis, some accompanied by soft tissue masses.
The most significant destructions are located in the S2-3 vertebral bodies, with compression of the adjacent sacral foramen.
FDG uptake is increased, SUVmax = 8.3, and the L4 vertebral body is flattened.
Overall bone density is decreased, the spinal alignment is normal, but some vertebral bodies show marginal osteophyte formation.
Multiple intervertebral disc bulges with pneumoconiosis and degeneration are present.
Internal fixation of the left femur with metal is ongoing.

Impression

1. a. Multiple space-occupying lesions in the liver with increased FDG metabolism, suggestive of malignancy, possibly hepatocellular carcinoma with intrahepatic metastasis, metastatic tumors cannot be ruled out; multiple lymph node metastases in the hilar region and retroperitoneum. b. Multiple bone metastases throughout the body. Pathological fracture of the L4 vertebral body. c. Gallstones with chronic cholecystitis. Increased local FDG uptake in the gallbladder, gallbladder cancer to be ruled out, please combine with enhanced MRI for comprehensive analysis.

2. Benign prostatic hyperplasia with calcification, uneven FDG metabolism, please follow up with PSA and MRI.

3. Chronic inflammatory nodules in the upper lobe of the right lung. Scattered post-inflammatory lesions in both lungs. Anemia changes, calcification of some arterial walls (including coronary arteries).

4. Cyst in the right lobe of the liver. Adrenal hyperplasia on the left side.

5. Chronic inflammatory changes in the antrum of the stomach.

6. Osteoporosis, degenerative changes in the spine, multiple intervertebral disc bulges with pneumoconiosis. Postoperative changes in the left femur.

7. The thyroid gland has uneven density and multiple nodules in both lobes. FDG metabolism is normal, suggesting nodular goiter. Please confirm with ultrasound examination.

8. Elderly patient with deep lacunar infarcts. Please confirm with MRI examination. Right maxillary sinus submucosal cyst.

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.
