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 with both arms raised, from the top of the skull to the upper thigh.
The brain morphology and structure were normal, with no abnormal density shadows seen in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The bilateral eyeballs had normal morphology and outlines, clear retrobulbar structures, and symmetrical optic nerves, with no abnormal FDG uptake.
The left maxillary sinus mucosa was slightly thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened; there was no stenosis in the bilateral pharyngeal recesses or Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear, and no abnormalities in FDG uptake were observed.
FDG uptake in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with slightly uneven density, and no abnormalities in FDG uptake were observed.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
A mixed ground-glass opacity was observed in the anterior segment of the right upper lobe, measuring approximately 2.3cm 1.6cm 0.9cm, with a mean CT value of -418 HU.
The borders were relatively clear, and FDG uptake was slightly increased (SUVmax = 2.7).
Multiple scattered solid and subsolid nodules, approximately 0.2cm?.6cm in length, were observed in both lungs; some had slightly indistinct margins, and FDG uptake was normal.
A few scattered mixed ground-glass opacities and linear areas of increased density were observed in the remaining lungs; FDG uptake was normal.
Partial pleural thickening was observed bilaterally; there was no pleural effusion or pneumothorax bilaterally.
A sac-like low-density lesion was observed near the trachea in the right upper mediastinum; FDG uptake was absent.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions; FDG uptake was normal.
Cardiac abnormalities were observed in part of the wall of the left coronary artery.
The esophagus was not dilated, and the wall was not significantly thickened or swollen.
FDG uptake was not increased.
The right lobe of the liver was enlarged and full, with irregular borders and widened fissures.
Large, slightly low-density masses were seen in the right lobe and left inner lobe of the liver, with some sections showing nodular fusion.
The largest mass measured approximately 18.6cm 13.9cm 24.4cm, with uneven density, an average CT value of 38 HU, and indistinct borders.
FDG uptake was unevenly increased, with SUVmax = 8.4.
The right branch and main trunk of the portal vein were slightly thickened, with increased FDG uptake, SUVmax = 5.9.
No dilation of intrahepatic or extrahepatic bile ducts was observed.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneum, and FDG uptake was normal.
Fluid accumulation was seen around the liver and spleen, in the bilateral paracolic gutter, and in the pelvic cavity.
The gallbladder was slightly full, with increased density within the gallbladder.
The gallbladder wall was not thickened, and local FDG uptake was normal.
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 abnormalities in FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormalities in FDG uptake.
The right adrenal gland is poorly visualized, while the left adrenal gland is slightly enlarged, with slightly increased FDG uptake (SUVmax = 1.7).
The stomach is not distended, with no obvious thickening of the gastric wall, and no obvious abnormalities in FDG uptake.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is normal in size and density, with no abnormally increased FDG uptake.
The bladder is poorly distended, with no obvious positive stones.
FDG uptake of the bones in the collection field is not abnormally increased.
The spinal alignment was normal, with some vertebral body margins showing osteophyte formation and calcification of the nuchal ligament; L4/5 and L5/S1 intervertebral disc herniation, the latter partially calcified with a small amount of air accumulation, and FDG uptake was normal.

Impression

1. a. Large, slightly low-density masses in the right lobe and left inner lobe of the liver (partially nodular fusion-like changes) with increased FDG metabolism, suggestive of hepatocellular carcinoma with intrahepatic metastasis. b. Slight thickening of the right branch and main trunk of the portal vein with increased FDG metabolism, suggestive of tumor thrombus formation. c. Liver cirrhosis. Cholestasis of the gallbladder. Abdominal and pelvic effusions.

2. a. Mixed ground-glass opacities in the anterior segment of the right upper lobe of the lung, with mildly increased FDG metabolism, suggestive of inflammatory lesions, atypical lung cancer to be ruled out, CT scan recommended in 1-3 months. b. Scattered chronic inflammatory nodules in both lungs are the primary consideration, scattered inflammation in both lungs (partially chronic inflammation and sequelae), CT scan recommended after anti-inflammatory treatment. c. Mild thickening of the pleura on both sides. Tracheal diverticulum. Calcification of the wall of part of the left branch of the coronary artery.

3. The right adrenal gland is poorly visualized, and the left adrenal gland shows mild hyperplasia.

4. Degenerative changes in the spine. L4/5 and L5/S1 disc herniation, the latter with partial calcification and pneumoconiosis.

5. Cranial scintigraphy showed no obvious abnormalities. Minor 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.
