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.
Both eyeballs were symmetrical, with no significant abnormalities.
The right ethmoid and maxillary sinus mucosa showed slight thickening, but the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The 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 palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
The lung markings are clear.
A ground-glass nodule in the apical segment of the right upper lobe, approximately 0.6 cm in long diameter, with a maximum CT value of -565 HU, was observed; FDG uptake was normal.
Several solid nodules were present in both lungs, the largest approximately 0.4 cm in diameter; FDG uptake was normal.
A few round or oval air-filled cavities were present in the upper lobes of both lungs.
Calcifications were present in the lower lobes of both lungs.
A few scattered linear lesions were present in both lungs; FDG uptake was normal.
No pleural thickening was observed bilaterally.
There was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
The cardiac chamber density was slightly lower than that of the myocardium; some arterial walls (including the coronary arteries) showed calcification.
No esophageal dilation, no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver margins are not smooth, and multiple irregular mixed-density nodules and masses are present within the liver.
The two largest nodules are located at the top of the diaphragm and the right posterior lobe, respectively, with indistinct borders, measuring approximately 6.5*7.5cm and 5.2*5.6cm, respectively.
Patchy high-density shadows are seen within these nodules, and FDG uptake is unevenly increased, with SUVmax=4.5 and 5.8.
Lymph nodes in the hepatic hilum, hepatogastric space, and parapancreatic head are visible, the largest with a short diameter of approximately 2.1cm, showing increased FDG uptake, with SUVmax=3.5.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall, and no abnormal local FDG uptake.
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 abnormal FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
A few exudative shadows were observed around both kidneys.
A small cystic lesion, approximately 0.7 cm in diameter, was observed in the left renal parenchyma.
FDG metabolism was not increased.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
Stomach distension was poor.
Thickening of the gastric wall on the lesser curvature of the gastric body was accompanied by increased FDG metabolism.
SUVmax = 3.0, with the thickest part approximately 1.7 cm.
Intestinal distension was unsatisfactory, with physiological uptake.
The prostate was of normal size, with patchy dense shadows inside.
FDG uptake was not abnormally increased.
Bladder distension was poor, with no obvious positive stones.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and L3/4 and L4/5 intervertebral disc bulging.
Patchy FDG uptake was observed bilaterally around the shoulders, with SUVmax = 3.9.
No abnormalities were found in systemic bone marrow FDG metabolism.

Impression

1. a. Multiple space-occupying lesions in the liver with elevated FDG metabolism, suggestive of malignancy, with a high probability of metastasis. Primary intrahepatic tumor with intrahepatic metastasis needs further investigation. Please combine tumor markers and enhanced MRI for comprehensive analysis. Metastasis to the hilar lymph nodes, hepatogastric space, and pancreatic head. b. Thickening of the gastric wall on the lesser curvature of the gastric body with elevated FDG metabolism, suggestive of gastric cancer. Further gastroscopy is recommended.

2. a. Ground-glass nodule in the apical segment of the right upper lobe, with normal FDG metabolism, suggestive of inflammation or atypical adenomatous hyperplasia. Follow-up is recommended. b. Chronic inflammatory micronodules (solid) in both lungs. Mild emphysema in the upper lobes of both lungs. Scattered post-inflammatory lesions in both lungs. Anemia changes, partial arterial wall calcification (including coronary arteries).

3. Small cyst in the left kidney. Calcification lesions in the prostate.

4. Degenerative changes in the spine, L3/4 and L4/5 disc bulge. Bilateral frozen shoulder.

5. Cranial scintigraphy showed no obvious abnormalities. Minor chronic inflammation of the right ethmoid and maxillary 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.
