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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, and no significant abnormalities were observed.
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 not abnormal.
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 seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Lymph nodes are visible in the right deep cervical space and right supraclavicular fossa; the largest has a short diameter of approximately 1.0 cm, with slightly increased FDG uptake (SUVmax = 2.5).
An irregular patchy nodule is visible in the anterior segment of the left upper lobe, adjacent to the mediastinum, with indistinct borders and spiculated edges, partially tractioning the adjacent pleura; it measures approximately 2.8*1.7*2.3 cm, with increased FDG uptake (SUVmax = 2.8).
The interlobular septa are thickened bilaterally; multiple blurred patchy and linear lesions are present in both lungs; patchy shadows are seen in the lower lobes of both lungs; FDG uptake is increased (SUVmax = 2.6).
Multiple solid nodules are also seen in both lungs; the largest is located in the inferior lingular segment of the left upper lobe, approximately 0.9 cm in diameter; FDG uptake is normal.
Multiple air-filled cavities are present in the upper lobes of both lungs; calcification is present in the apical-posterior segment of the left upper lobe.
Minimal pleural effusion bilaterally.
Multiple lymph nodes were observed in the bilateral hilar regions, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and right axilla.
The largest, located subcarinal region, had a short diameter of approximately 1.3 cm.
FDG uptake was increased, with an SUVmax of 4.0.
Cardiac findings were normal.
Partial arteriosclerosis was observed.
Esophageal dilation was not observed, and the esophageal wall showed no significant thickening or mass.
FDG uptake was not increased.
Liver morphology and size were normal, with smooth liver margins and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no significant widening, and intrahepatic and extrahepatic bile ducts were not dilated.
Gallbladder morphology and size were normal, with punctate dense shadows within the gallbladder.
The gallbladder wall showed no thickening, and local 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 not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size.
Multiple dense nodules are present in the right renal pelvis and calyces, the largest measuring approximately 2.3 cm in long diameter.
There is hydronephrosis in the right renal pelvis.
The left renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is poorly filled, with thickening of the antral wall and slightly increased FDG uptake (SUVmax = 1.2).
The intestines are poorly filled, exhibiting physiological uptake.
The prostate is full and homogeneous in density, with punctate dense shadows and uneven FDG uptake.
The bladder is poorly filled, with no obvious positive stones.
Multiple lymph nodes were observed in the hepatogastric space and retroperitoneum, the largest with a short diameter of approximately 0.9 cm, showing increased FDG uptake (SUVmax = 3.2).
Localized osteolytic bone destruction was observed in the C7 vertebral body and the right sacrum, accompanied by increased FDG uptake (SUVmax = 4.9).
Patchy high-density lesions were present within the T5 vertebral body, showing increased FDG uptake (SUVmax = 2.6).
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 intervertebral disc bulges.

Impression

1. a. Irregular plaque-like lesions with increased FDG metabolism in the anterior segment of the left upper lobe, adjacent to the mediastinum, lung cancer is the primary consideration; suspected space-occupying lesions in both lower lobes; signs of lung cancer-related lymphangitis in both lungs. The above should be compared with older scans and closely monitored. b. Multiple lymph nodes in the bilateral hilar, mediastinal, right axilla, right supraclavicular fossa, right deep cervical space, hepatogastric space, and retroperitoneal region showing increased FDG metabolism, some suggestive of metastases. c. Metastases in the C7 vertebral body and right sacral region. T5 vertebral metastasis to be ruled out.

2. Chronic inflammatory nodules in both lungs; CT follow-up is recommended to rule out partial metastases. Emphysema in both upper lobes; calcification in the left upper lobe. Micropleural effusion in both pleural cavities. Partial arteriosclerosis.

3. Benign prostatic hyperplasia with calcification and uneven FDG metabolism; PSA testing is recommended.

4. Gallstones. Right kidney stones with hydronephrosis.

5. Chronic inflammatory changes in the gastric antrum; please follow up with endoscopy.

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

7. No obvious abnormalities were found on cranial scintigraphy.

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.
