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; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and without significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
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.
An irregular nodule measuring approximately 2.0 1.2 1.3 cm was seen at the opening of the posterior basal segment of the right lower lobe, with lobulated and spiculated margins; FDG metabolism was increased, SUVmax = 3.0, and the corresponding bronchus was compressed; several solid micronodules, approximately 0.2?.3 cm in long diameter, with clear borders, were seen in both lungs; FDG metabolism was normal.
An air-filled cavity was seen in the right upper lobe; a few speckled and linear foci were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was seen 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.
Some arterial walls showed calcification (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver outline was irregular, with smooth borders and widened hepatic fissures; an irregular low-density mass measuring approximately 4.6 4.0 cm was observed in the lower segment of the right anterior lobe of the liver, with unevenly increased FDG metabolism (SUVmax = 2.5).
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and linear dense shadows within the gallbladder wall; FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma; a linear dense shadow is seen in the upper segment of the right ureter, with a long diameter of approximately 1.0 cm, and mild hydronephrosis of the proximal ureter and renal pelvis, with no obvious abnormalities in FDG uptake.
No obvious abnormalities were seen in bilateral adrenal glands.
The stomach is poorly distended, with no obvious thickening of the stomach 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 shape and size, with uniform density, and no abnormal FDG metabolism was observed.
The bladder is generally full, with no obvious positive stones seen.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious effusion was seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Bone mineral density is decreased in all bones; systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass in the lower segment of the right anterior lobe of the liver, with unevenly increased FDG metabolism, suggesting possible hepatocellular carcinoma. Please combine with enhanced MRI for comprehensive analysis. b. Cirrhosis.

2. a. An irregular nodule at the opening of the posterior basal segment of the right lower lobe, with increased FDG metabolism, suggesting possible lung cancer. Inflammatory lesions need to be ruled out. Please compare with old films and have a follow-up HRCT in 3 months. b. Several small chronic inflammatory nodules (solid) in both lungs are highly likely. Follow-up CT is recommended. The upper lobe of the right lung contains a pneumocystic cavity. A few chronic inflammations and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Gallstones.

4. Stone in the upper segment of the right ureter, with mild hydronephrosis of the proximal ureter and renal pelvis.

5. Osteoporosis. Osteophytes in the cervical, thoracic, and lumbar vertebrae. L4/5 and L5/S1 intervertebral disc bulges.

6. Cranial scintigraphy showed no abnormalities.

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.
