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: Brain morphology and structure were normal, with a few patchy low-density shadows in the deep brain regions; FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no obvious abnormalities.
The right ethmoid and maxillary sinuses showed mucosal thickening, but the sinus walls were intact.
The nasopharyngeal wall was not thickened; FDG uptake was normal.
The pharyngeal recesses were symmetrical; 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 laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size.
A low-density nodule measuring approximately 1.0 0.8 cm is seen in the left lobe, with no abnormal FDG uptake.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
A soft tissue mass measuring approximately 4.9 4.2 cm is seen in the right upper lobe, adjacent to the mediastinum, with spiculated and lobulated margins, traction on the pleura.
FDG metabolism is increased, SUVmax = 9.5.
Multiple solid small nodules are present in both lungs, with clear borders.
The largest is located in the lateral basal segment of the left lower lobe, with a long diameter of approximately 0.7 cm.
FDG uptake is normal.
A few cystic lucent shadows and linear shadows are seen in both lungs.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
Enlarged lymph nodes are seen in the pretracheal space of the mediastinum and at the aortopulmonary window, the largest with a short diameter of approximately 1.2 cm.
FDG metabolism is increased, SUVmax = 5.6.
Calcification of some arterial walls (including coronary arteries).
Cardiac imaging normal.
Esophageal dilation, wall thickening, or masses were not observed; FDG uptake was not increased.
Liver morphology and size were normal; liver margins were smooth; hepatic fissures were not widened; plain CT scan showed no abnormal density shadows in the liver parenchyma; FDG uptake was normal.
The main portal vein was not significantly widened; intrahepatic and extrahepatic bile ducts were not dilated.
Gallbladder morphology and size were normal; gallbladder wall thickening was not observed; local FDG uptake was normal.
Pancreas morphology was normal; parenchyma showed no abnormal density shadows; the main pancreatic duct was not widened; FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is seen.
The bladder wall is not abnormally thickened, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdominopelvic region or retroperitoneal area.
No obvious effusion is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L2-S1 intervertebral disc bulging.
Systemic bone FDG metabolism is normal.

Impression

1. a. Right upper lobe lung mass, elevated FDG metabolism, suggestive of peripheral lung cancer. b. Mediastinal lymph node metastasis. c. Multiple solid nodules in both lungs, normal FDG metabolism, suggestive of chronic inflammatory nodules, some metastasis to be ruled out; regular CT scans for comparison are recommended. d. Minor emphysema and remnants of chronic inflammation in both lungs. Some arterial wall calcification (including coronary arteries).

2. Minor ischemic lesions deep in the brain. Age-related brain changes; MRI is recommended.

3. Chronic inflammation of the right ethmoid and maxillary sinuses.

4. Partial vertebral osteophyte formation. L2-S1 intervertebral disc bulge.

5. Low-density nodule in the left lobe of the thyroid gland, normal FDG metabolism, suggestive of adenoma; ultrasound is 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.
