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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: A few punctate low-density shadows were observed in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
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.
An irregular mass measuring approximately 4.8 3.0 cm was observed in the posterior segment of the left upper lobe, adjacent to the mediastinum, with lobulated and spiculated margins; FDG metabolism was elevated (SUVmax = 12.3), and the corresponding bronchus was obstructed.
Multiple solid nodules were observed in the pleura of the left oblique fissure, the larger ones fused into a mass, with a long diameter of approximately 1.3 cm; FDG metabolism was elevated (SUVmax = 4.9).
A linear FDG metabolism was observed in the pleura of the left chest wall (SUVmax = 4.3); a small amount of pleural effusion was observed in the left side.
Several small solid nodules were observed in both lungs, with a long diameter of approximately 0.2?.3 cm and clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also observed in both lungs; FDG metabolism was normal.
Multiple enlarged lymph nodes were observed in the bilateral hilar regions, below the tracheal carina, and in the left internal mammary chain, with the largest measuring approximately 1.5 cm in short diameter.
FDG metabolism was increased, with an SUVmax of 4.4.
The cardiac silhouette appeared normal.
Some arterial walls showed calcification.
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissures.
Multiple cystic lesions were observed within the liver, the largest measuring approximately 0.8 cm in long diameter, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder's shape and size were normal, with no thickening of the wall, but nodular dense shadows were observed within, and localized FDG uptake was normal.
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.
A 1.1cm cystic low-density lesion is seen at the upper pole of the left kidney.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is normal.
The right adrenal gland shows nodular thickening of the internal and external branches, with a long diameter of approximately 1.1cm.
FDG metabolism is increased, with SUVmax=5.6.
The left adrenal gland shows no obvious abnormalities on contrast.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is normal.
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 metabolism is observed.
The bladder is generally full, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulges.
Multiple ribs bilaterally, multiple vertebral bodies and appendages of the spine, the sacrum, and the right iliac bone show bone destruction.
FDG metabolism is increased, with SUVmax = 5.9.

Impression

1. a. Mass in the posterior segment of the left upper lobe, with increased FDG metabolism, suggestive of lung cancer. b. Metastasis to the left hilar, subcarinal, and left internal mammary chain lymph nodes. Reactive hyperplasia of the right hilar lymph nodes. c. Left pleural metastasis. Small amount of pleural effusion on the left side. d. Multiple bone metastases throughout the body. Right adrenal gland metastasis.

2. Several small (solid) chronic inflammatory nodules in both lungs are possible; CT follow-up is recommended to rule out metastasis. A few chronic inflammations and old lesions in both lungs. Some arterial wall calcification.

3. Multiple liver cysts. Gallstones. Left renal cyst.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

5. A few ischemic lesions in the deep bilateral brain regions.

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.
