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 calcifications, approximately 1.9 cm in length, were observed in the right cerebellum; FDG metabolism was normal.
No abnormal density shadows were observed in the remaining brain parenchyma, and 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.
Both eyeballs were symmetrical, with no obvious abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; 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 bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were observed 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 uniform density, and no abnormal FDG uptake.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Multiple nodules of varying sizes were observed in the right lung and subpleural region, predominantly in the lateral basal segment of the right lower lobe and the right middle lobe, measuring approximately 2.8 2.3 cm and 2.1 2.0 cm respectively, with lobulated and spiculated margins.
FDG metabolism was increased in all nodules, with SUVmax = 8.9, and some were adherent to the adjacent pleura.
Multiple solid micronodules were also observed in both lungs, with a long diameter of approximately 0.2?.4 cm and clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also observed in both lungs, with no abnormal FDG metabolism.
Extensive thickening of the right pleura and interlobar pleura with multiple nodular shadows was observed, some with increased FDG metabolism (SUVmax = 3.4); moderate pleural effusion was observed in the right side.
Several enlarged lymph nodes were observed in the right hilum, pretracheal space, and below the carina, the largest with a short diameter of approximately 1.0 cm.
FDG metabolism was increased, with SUVmax = 4.5.
The cardiac silhouette was normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissure, and no significant abnormal density shadows in the liver parenchyma on plain CT scan.
FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
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 was poorly distended, with no obvious thickening of the stomach wall, and FDG uptake was not significantly abnormal.
Intestinal distended, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
Prostate morphology and size were normal, with uniform density, and no abnormal FDG metabolism was observed.
Bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation 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 T9 vertebral body, increased FDG metabolism, and SUVmax = 11.4.

Impression

1. a. Multiple lesions in the right lung and subpleural region, with elevated FDG metabolism, suggestive of lung cancer with metastases. The nodule in the lateral basal segment of the right lower lobe is most likely the primary lesion; please correlate with clinicopathology. b. Multiple small nodules in both lungs, suggestive of metastases. Multiple lymph node metastases in the right hilum and mediastinum. Right pleural metastasis. T9 vertebral body bone metastasis. c. Moderate pleural effusion on the right side.

2. Right cerebellar calcification.

3. Cervical, thoracic, and lumbar vertebral osteophytes. L4/5 and L5/S1 intervertebral disc bulges.

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.
