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 hands 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 eyeballs were normal in shape and outline, with clear retrobulbar structures and symmetrical optic nerves; no abnormal FDG uptake was observed.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; 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; 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.
Lung markings were clear bilaterally.
Multiple solid micronodules and calcifications were observed in both lungs, with regular shapes, clear borders, and a long diameter of approximately 0.2?.5 cm.
FDG uptake was normal.
A few linear and flocculent density shadows were also observed in both lungs, with no abnormal FDG uptake.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
The liver had an irregular shape, irregular borders, and widened fissures.
CT scan revealed irregular, slightly low-density nodules and masses in the right lobe of the liver, with uneven density, some protruding into the liver capsule, and indistinct borders.
The largest nodule measured approximately 13.3 cm 11.0 cm, with unevenly increased FDG uptake (SUVmax = 7.2).
A localized area of increased FDG uptake was observed in the right branch of the portal vein, with an uptake cross-section of approximately 5.0 cm 2.9 cm and an SUVmax of 7.8.
A linear area of increased FDG uptake was observed in the region from the inferior vena cava to the right atrium, with an SUVmax of 5.8 and an uptake cross-section of approximately 2.0 cm 1.7 cm.
Multiple lymph nodes were visualized in the hepatogastric space, hepatic hilum, and hilar space, the largest with a short diameter of approximately 1.2 cm, showing increased FDG uptake and an SUVmax of 3.1.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was 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.
The spleen was slightly enlarged, with no abnormal 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 no obvious abnormal FDG uptake was observed.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
Gastric distension was poor, with slight thickening of the gastric wall and a slightly increased FDG uptake (SUVmax = 2.4).
Intestinal distension was poor, with no significant thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate showed no abnormalities in morphology or size, and no significant abnormal density shadows in the parenchyma; FDG uptake was normal.
The bladder showed poor distension, with no obvious positive stones.
No significant fluid accumulation was observed in the abdomen or pelvis.
Some vertebral body margins showed osteophyte formation.
Some nuchal ligaments showed calcification, and L4/5 and L5/S1 intervertebral disc bulges were observed; FDG uptake was normal.

Impression

1. a. Irregular, slightly low-density nodules and masses in the right lobe of the liver, with increased FDG metabolism, suggestive of hepatocellular carcinoma (highly likely) with intrahepatic lesions or metastatic tumor formation. b. Tumor thrombus formation in the right branch of the portal vein and the inferior vena cava. Partial lymph node metastasis in the hepatogastric space, hepatic hilum, and hilar space needs to be ruled out; close observation is recommended. c. Liver cirrhosis. Slightly enlarged spleen.

2. Multiple chronic inflammatory micronodules and calcifications in both lungs; please follow up with CT to rule out mixed metastatic lesions. A few post-inflammatory lesions in both lungs. Partial arteriosclerosis.

3. Slightly increased FDG metabolism in the gastric wall, suggestive of physiological metabolism or chronic inflammatory changes; please follow up with endoscopy.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

5. No obvious abnormalities were found on cranial scintigraphy.

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.
