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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging was performed with arms raised, from the top of the skull to the upper thighs: Brain morphology and structure were normal, with calcification of the falx cerebri.
No abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
The cisterna magna was widened, but other ventricles, sulci, fissures, and cisterns were not widened.
The ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
The right maxillary sinus mucosa was thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, 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.
Bilateral palatine tonsil regions showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in morphology and size, with slightly uneven density, and FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A small solid nodule with clear borders, approximately 0.5 cm in length, was seen in the left main bronchus.
Scattered small solid nodules with clear borders, approximately 0.2?.4 cm in diameter, were observed in both lungs; FDG uptake was normal in all cases.
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.
No esophageal dilation, significant wall thickening, or mass was observed; FDG uptake was normal.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A slightly low-density nodule with indistinct borders, approximately 2.9 cm 2.4 cm in size, was seen in the posterolower segment of the right lobe of the liver; FDG uptake was increased, with SUVmax = 3.4.
A slightly low-density nodule with clear borders, approximately 1.0 cm in length, was seen in the upper segment of the left lateral lobe of the liver; FDG uptake was normal.
The main portal vein is widened, but no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is normal in shape and size, with increased density within the gallbladder, but no thickening of the gallbladder wall, and no abnormal 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.
The spleen is slightly enlarged, but its density and FDG uptake are normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no widening of the renal pelvis, calyces, or ureters; no obvious abnormal FDG uptake is observed.
Bilateral adrenal gland imaging is normal.
The stomach is poorly distended, with slight thickening of the gastric wall at the cardia and slightly increased FDG uptake (SUVmax = 2.8).
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The prostate is normal in shape and size, with uniform density, and no abnormal FDG uptake is observed.
The bladder wall is not abnormally thickened, and no obvious positive stones are observed within it.
No enlarged lymph nodes were observed in the abdominopelvic region or retroperitoneal area.
A small amount of pelvic effusion was present.
The spinal alignment was normal, with calcification of the nuchal ligament.
Some vertebral bodies showed marginal osteophyte formation.
Systemic FDG uptake of bone was normal.

Impression

1. a. Slightly low-density nodule with increased FDG metabolism in the lower right lobe of the liver, suggestive of hepatocellular carcinoma. b. Hemangioma in the upper left lateral lobe of the liver. Widening of the main portal vein. Slightly enlarged spleen. Cholestasis in the gallbladder.

2. a. Small nodule in the left main bronchus, FDG metabolism normal, currently considered benign, follow-up CT recommended. b. Scattered chronic inflammatory micronodules (solid) in both lungs.

3. Physiological changes or inflammatory lesions in the gastric cardia, follow-up gastroscopy recommended. Small amount of pelvic effusion.

4. Degenerative changes in the spine.

5. Calcification of the falx cerebri, cisterna magna and occipital region. Right maxillary sinusitis.

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.
