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 punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no obvious abnormalities.
Thickening of the left maxillary sinus mucosa was observed, but no thickening was seen in the mucosa of the other paranasal sinuses; the sinus walls were intact.
The nasal septum was deviated; the nasopharyngeal wall was not thickened, and 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 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, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
The lung markings are clear.
An irregular, patchy soft tissue density shadow with indistinct borders, measuring approximately 2.7*2.2*1.9cm, is present in the anterior segment of the right upper lobe near the hilum; FDG uptake is increased (SUVmax=16.1), and the adjacent bronchus is truncate.
A ground-glass nodule with indistinct borders, approximately 0.9cm in long diameter, with a maximum CT value of -592HU, is present in the posterior segment of the left upper lobe; FDG uptake is normal.
A few linear lesions are present in both lungs; FDG uptake is normal.
No pleural thickening or pleural effusion/pneumothorax is observed bilaterally.
Right hilar lymph nodes are visible; the largest has a short diameter of approximately 1.3cm; FDG uptake is increased (SUVmax=12.6).
No significantly enlarged lymph nodes were seen in the mediastinum.
Cardiac imaging: No abnormalities observed.
Calcification of some arterial walls (including coronary arteries).
Esophageal dilation: No significant thickening or mass observed in the esophagus; FDG uptake not increased.
Liver: No significant abnormalities in shape or size; smooth liver margins; no widening of the hepatic fissure; small cystic lesion in the right posterior lobe of the liver, approximately 0.7 cm in diameter; FDG uptake not abnormal.
Main portal vein: No significant widening; no dilation of intrahepatic or extrahepatic bile ducts.
Gallbladder: No abnormalities in shape or size; no thickening of the gallbladder wall; localized FDG uptake not abnormal.
Pancreas: Normal shape; no significant abnormal density shadows observed in the parenchyma; no widening of the main pancreatic duct; FDG uptake not significantly abnormal.
Spleen: No abnormalities in shape, size, density, or FDG uptake.
Soft tissue density nodule adjacent to the spleen, approximately 0.8 cm in diameter; FDG uptake not abnormal.
Both kidneys are normal in shape and size, with multiple cystic lesions in the renal parenchyma, the largest being approximately 1.7 cm in diameter.
FDG uptake is absent.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
Stomach distension is poor, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake is increased, SUVmax = 4.5.
Intestinal distension is unsatisfactory, but intestinal uptake is physiological.
The prostate is normal in size and density, with no abnormally increased FDG uptake.
Bladder distension is poor, and no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation is 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 localized decreased density in the left 6th rib, but FDG metabolism is normal.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass near the hilum in the anterior segment of the right upper lobe with increased FDG metabolism, suggestive of lung cancer. Right hilar lymph node metastasis. b. Ground-glass nodule in the apical-posterior segment of the left upper lobe, FDG metabolism normal, suggestive of inflammation or atypical adenomatous hyperplasia; CT follow-up recommended. A few post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

2. Small cyst in the right lobe of the liver. Accessory spleen. Bilateral renal cysts.

3. Chronic inflammatory changes in the gastric wall; please follow up with endoscopy.

4. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulges. Benign lesion in the left 6th rib is the primary consideration; follow-up to rule out metastasis is recommended.

5. Deep lacunar infarcts in the brain. Inflammation of the left maxillary sinus.

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.
