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.
The eyeballs were symmetrical, with no significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening; FDG uptake was normal; the pharyngeal recesses were symmetrical; there was no narrowing 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 parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
Thyroid gland is normal in shape and size, with uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
A soft tissue mass was seen in the basal segment of the left lower lobe, with spiculated and lobulated margins, pleural traction, and local bronchial obstruction.
CT value is approximately 37 HU, size approximately 6.2*5.7cm, FDG metabolism is increased, SUVmax=16.8.
Scattered linear and calcified lesions were seen in both lungs.
Multiple cystic lucent shadows were seen in both lungs.
No pleural thickening was seen bilaterally; no pleural effusion or pneumothorax was seen bilaterally.
Enlarged lymph nodes were seen in the left hilum and below the left carina, the largest with a short diameter of approximately 1.1cm, FDG metabolism is increased, SUVmax=6.4.
Post-coronary artery stenting.
Calcification of the aortic arch and abdominal aortic wall was observed.
No abnormalities were seen in the cardiac silhouette.
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 was observed in the intrahepatic or extrahepatic bile ducts.
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; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, or FDG uptake.
Scattered punctate calcifications were observed within the spleen.
Both kidneys are normal in shape and size.
A punctate dense shadow is seen in the right kidney, and multiple cystic lesions are seen in the left kidney, the largest being approximately 1.0 cm in diameter.
FDG uptake is normal.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is poorly distended, but the stomach wall is not significantly thickened, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with continuous FDG metabolism increased in parts of the colon and rectum (SUVmax = 5.9).
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is observed.
The bladder is generally full, 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 L5/S1 disc bulge with pneumothorax.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Mass in the lower lobe of the left lung, with increased FDG metabolism, suggestive of lung cancer; please confirm with pathology. b. High probability of metastasis to the left hilar and left subcarinal lymph nodes. c. Scattered chronic inflammation and sequelae in both lungs. Emphysema in both lungs.

2. Post-coronary artery stenting. Calcification of the aortic arch and abdominal aortic wall.

3. Scattered punctate calcifications in the spleen. Right kidney stone. Multiple cysts in the left kidney.

4. Continuous increased FDG metabolism in parts of the colon and rectum, likely due to inflammatory or physiological uptake; colonoscopy follow-up is recommended.

5. Partial vertebral osteophyte formation. L5/S1 intervertebral disc bulge with pneumothorax.

6. A few ischemic lesions deep in the brain. Age-related brain changes suggest an MRI scan.

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.
