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, a whole-body PET/CT scan was performed.
The whole-body scan showed: Patchy low-density shadows in the right cerebellum and bilateral basal ganglia, with no significant abnormalities in FDG uptake.
Enlargement of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles with no midline shift.
Symmetrical bilateral eyeballs with no significant abnormalities.
Thickening of the bilateral maxillary sinus mucosa, with intact sinus walls.
No thickening of the nasopharyngeal wall, with no abnormalities in FDG uptake; symmetrical bilateral pharyngeal recesses; no stenosis of the Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces with no abnormalities in FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
A soft tissue nodule measuring approximately 1.0 0.9 cm was found in the left parotid gland, with increased FDG metabolism (SUVmax = 6.5); no abnormal density shadows were seen in the right parotid and submandibular glands.
No abnormalities were observed in the morphology and structure of the laryngopharynx.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Increased translucency was observed in both lungs, accompanied by multiple air-filled cavities; an irregular mass measuring approximately 7.8 5.6 3.6 cm was observed in the posterior basal segment of the right lower lobe, closely adhering to the subpleural region, with spiculated margins; FDG metabolism was increased, SUVmax = 8.4; multiple scattered punctate lesions, calcifications, and linear lesions were also observed in both lungs; FDG metabolism was normal.
A small amount of pleural effusion was observed bilaterally.
Multiple lymph nodes were observed in the right hilum, pretracheal space, para-aortic arch, aortopulmonary window, and subcarinal region; the largest was located in the right hilum, with a short diameter of approximately 1.8 cm; FDG metabolism was increased, SUVmax = 15.4.
No abnormalities were observed in the cardiac silhouette.
Calcification of some arterial walls (including coronary arteries).
Esophageal dilatation, no significant thickening or mass in the esophagus, and no increased FDG uptake.
Poor gastric filling, no significant thickening of the gastric wall, and no significant abnormality in FDG uptake.
Poor intestinal filling, no significant thickening or mass in the intestinal wall, and physiological FDG uptake.
Liver morphology and size are normal, liver margins are smooth, liver fissures are not widened, and no significant abnormal density shadows are seen in the liver parenchyma on plain CT scan; FDG uptake is normal.
The main portal vein is not significantly widened, and no dilatation of intrahepatic or extrahepatic bile ducts is observed.
Gallbladder morphology and size are normal, gallbladder wall is not thickened, and local FDG uptake is normal.
Pancreas morphology is normal, no significant abnormal density shadows are seen in the parenchyma, the main pancreatic duct is not widened, and FDG uptake is normal.
Spleen morphology, size, density, and FDG uptake were normal.
A cystic lesion was seen in the left kidney, approximately 1.7 cm in long diameter, with absent FDG uptake.
The right kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
Punctate dense shadows were seen in the right renal calyces; the renal pelvis, calyces, and ureter were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland contrast was normal.
The prostate was normal in shape and size, with uniform density, and no abnormal FDG metabolism was observed.
A small amount of fluid was observed in the tunica vaginalis of both testes.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneal region.
No significant fluid accumulation was seen in the abdomen or pelvic cavity.
Decreased bone density in all bones; spinal alignment normal, with marginal osteophyte formation in some vertebral bodies, and L4/5 and L5/S1 disc bulging.
Multiple vertebral wedging deformities in the thoracic and lumbar spine, most notably T7 and L5; FDG metabolism normal.
Systemic bone marrow FDG metabolism normal.

Impression

1. a. Space-occupying lesion in the posterior basal segment of the right lower lobe, with increased FDG metabolism, consistent with lung cancer. b. Right hilar lymph node metastasis. Reactive hyperplasia of mediastinal lymph nodes. Small amount of pleural effusion bilaterally. c. Scattered chronic inflammation and old lesions in both lungs. Emphysema with bullae in both lungs. Calcification of some arterial walls (including coronary arteries).

2. Softening lesions in the right cerebellum and bilateral basal ganglia, age-related brain changes. Chronic inflammation of bilateral maxillary sinuses.

3. Left renal cyst. Right renal calculus. Small amount of hydrocephalus bilaterally.

4. Degenerative changes in the spine. L4/5, L5/S1 intervertebral disc bulge. Multiple old compression fractures of the thoracic and lumbar vertebrae, most notably T7 and L5. Osteoporosis.

5. Soft tissue nodule in the left parotid gland with increased FDG metabolism, suggestive of adenolymphoma, MRI follow-up recommended.

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.
