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: A few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious 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 normal.
The pharyngeal recesses were symmetrical bilaterally, 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.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Several small lymph nodes are seen in the bilateral deep cervical spaces and submandibular region, with a short diameter of approximately 0.2-0.6 cm; FDG metabolism is normal.
A large, irregular mass is seen in the posterior segment of the left lower lobe, measuring approximately 8.99.67.2 cm, with lobulated and spiculated margins; FDG metabolism is increased (SUVmax=10.6), with corresponding bronchial obstruction and multiple patchy and flocculent shadows around it; several solid micronodules are seen in both lungs, with a long diameter of approximately 0.2-0.4 cm and clear borders; FDG metabolism is normal.
A few punctate and linear lesions are also seen in both lungs; FDG metabolism is normal.
The pleura is slightly thickened bilaterally; there is no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the left hilum, pretracheal space, para-aortic arch, aortic window, and below the carina, the largest measuring approximately 2.0 cm in short diameter.
FDG metabolism was increased, with SUVmax = 6.6.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Several cystic lesions were observed within the liver, the largest approximately 0.5 cm in long diameter, with absent FDG uptake.
The main portal vein was not significantly widened, and intrahepatic and extrahepatic bile ducts were not dilated.
The gallbladder's shape and size were normal, the wall was not thickened, and local FDG uptake was normal.
Fatty infiltration was observed in the pancreas, but the main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
Stomach distension was poor, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal distension was unsatisfactory, with increased FDG metabolism in some intestinal segments (SUVmax = 5.1).
The prostate was normal in shape and size, with uniform density, and no abnormal FDG metabolism was observed.
Bladder distension was normal, with no obvious positive stones.
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.
There is bone destruction in the T7 vertebral body, increased FDG metabolism, and SUVmax = 7.2.

Impression

1. a. A large mass in the posterior segment of the left lower lobe, with increased FDG metabolism, suggestive of lung cancer with surrounding inflammation. Multiple lymph node metastases in the left hilum and mediastinum. T7 vertebral metastasis is highly probable. b. Several small chronic inflammatory nodules (solid) in both lungs are highly probable; CT scan for comparison is recommended. A few chronic inflammations and old lesions in both lungs. Some arterial wall calcification.

2. A few ischemic lesions in the deep bilateral brain; age-related brain, MRI is recommended.

3. Small liver cysts. Fatty infiltration of the pancreas.

4. Increased FDG metabolism in some intestinal segments, suggestive of inflammatory or physiological uptake.

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

6. Reactive hyperplasia of bilateral cervical lymph nodes.

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.
