Whole-body 18F-FDG PET/CT scan in a patient with Lung 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, and resting, 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.
The eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, 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 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 glands.
The laryngopharynx morphology and structure were normal.
The bilateral submandibular glands were full in shape, with increased FDG metabolism (SUVmax = 6.3).
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 mass measuring approximately 3.6 2.8 cm was seen in the posterior segment of the right upper lobe, containing irregular air-filled cavities with lobulated and spiculated margins; FDG metabolism was increased (SUVmax = 6.8).
The bronchus in the posterior segment of the right upper lobe was obstructed; linear and patchy high-density shadows were seen distal to the lesion.
Multiple scattered patchy ground-glass opacities were seen in both lungs.
Localized increased FDG uptake was seen in the bronchial region of the posterior basal segment of the right lower lobe (SUVmax = 4.3), with slightly thickened local bronchial walls and an uptake length of approximately 1.5 cm.
Multiple punctate, calcified, and linear lesions were seen in both lungs; scattered air-filled cavities were seen in both lungs, with some bullae forming; FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
A slightly enlarged lymph node was observed in the right hilum, with a short diameter of approximately 1.0 cm, showing increased FDG metabolism (SUVmax = 4.8).
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (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's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
A low-density nodule, approximately 2.0 cm in long diameter, with indistinct borders, was observed in the left medial lobe of the liver, with no abnormal FDG metabolism.
Several small cystic lesions were also observed in the liver parenchyma, the largest being approximately 0.5 cm in long diameter in the left lobe.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal, 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.
The main pancreatic duct is not widened, and FDG uptake is normal.
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.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly filled, with slight thickening of the gastric body wall in some areas.
FDG metabolism is increased, with SUVmax = 7.7.
The intestines are poorly filled, with increased FDG metabolism in some areas, with SUVmax = 4.5.
FDG metabolism at the anus is increased, with SUVmax = 5.3.
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is observed.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The L2 and L3 vertebral bodies were slightly displaced posteriorly, and the L1 and L2 vertebral bodies showed slight flattening.
Osteophyte formation was observed at the margins of some vertebral bodies.
The L4/5 and L5/S1 intervertebral discs bulged, and the L1-3 intervertebral discs contained pneumothorax.
Calcification of the nuchal ligament was present.
The cortical bone of the left 5th and 6th ribs was incomplete, and FDG metabolism was normal.

Impression

1. a. A mass in the posterior segment of the right upper lobe, with increased FDG metabolism, suggestive of lung cancer, accompanied by distal obstructive changes. Possible right hilar lymph node metastasis. b. Scattered inflammation and remnants in both lungs; CT follow-up is recommended after anti-inflammatory treatment. Emphysema, bullae. Calcification of some arterial walls (including coronary arteries).

2. Slight thickening of part of the gastric body wall, with increased FDG metabolism, suggestive of gastritis; gastroscopy is recommended to rule out other possibilities.

3. A low-density nodule in the left inner lobe of the liver, with normal FDG metabolism, suggestive of hemangioma; contrast-enhanced MRI is recommended. Liver cyst.

4. Increased FDG metabolism in part of the intestinal tract, likely due to inflammatory uptake; hemorrhoidal changes.

5. Degenerative changes in the spine; lumbar vertebral instability, mild wedging of the L1 and L2 vertebral bodies. L4/5 and L5/S1 intervertebral disc bulges; L1-3 intervertebral disc pneumoconiosis and degeneration. Post-fracture changes of the left 5th and 6th ribs.

6. Cranial scintigraphy showed no abnormalities. Bilateral submandibular gland physiological uptake is highly probable.

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.
