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: A few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
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 normal.
The pharyngeal recesses were symmetrical bilaterally, 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.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology or 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.
Increased translucency in both lungs, with multiple air-filled cavities; an irregular mass measuring approximately 6.1 5.4 cm is seen in the right hilum, with increased FDG metabolism (SUVmax = 15.8), stenosis/occlusion of the middle and lower lobe bronchi, and obstructive changes distal to the mass; patchy and linear lesions are seen in the remaining lungs, with normal FDG uptake in all cases; extensive thickening of the right pleura, with increased FDG metabolism (SUVmax = 10.9).
Located pleural effusion in the right side and a small amount of pleural effusion in the left side.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and right supraclavicular fossa.
The largest lymph node had a short diameter of approximately 2.2 cm.
FDG metabolism was increased, with an SUVmax of 12.2.
Some arterial walls showed calcification.
The esophagus was not dilated, and the wall showed no significant thickening or mass.
FDG uptake was not increased.
The cardiac chamber density was lower than that of the myocardium.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Multiple cystic lesions were observed within the liver, the largest with a long diameter of approximately 1.2 cm, showing absent FDG uptake.
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, and the gallbladder wall showed no thickening.
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, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show nodular thickening, more pronounced on the left, with a long diameter of approximately 1.0 cm.
FDG metabolism is increased, with SUVmax = 8.9.
The stomach is poorly filled, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly filled, 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 observed.
The bladder is generally full, with no obvious positive stones.
Irregular thickening of the greater omentum, mesentery, liver capsule, and vesicorectal pouch, presenting as multiple flocculent or nodular lesions; elevated FDG metabolism; SUVmax = 4.5.
Significant fluid accumulation in the abdomen and pelvis.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies; L4/5 and L5/S1 intervertebral disc bulges.
Bone destruction was observed in the right scapula, right humeral head, left clavicle, multiple ribs bilaterally, multiple vertebrae and their appendages in the spine, sacrum, multiple areas of the pelvis, and the upper segments of both femurs.
FDG metabolism was increased, with SUVmax=27.9.
Decreased muscle density was observed in multiple areas of the bilateral gluteal muscles, left vastus lateralis, left vastus intermedius, right pectineus, bilateral psoas major, bilateral erector spinae, right infraspinatus, bilateral upper arm muscles, and right forearm muscles.
FDG metabolism was increased, with SUVmax=21.2.

Impression

1. a. Right hilar mass with elevated FDG metabolism, suggestive of central lung cancer with obstructive changes. b. Multiple lymph node metastases in the right hilum, mediastinum, and right supraclavicular fossa. c. Extensive right pleural metastasis. Located pleural effusion on the right side, small amount of pleural effusion on the left side. d. Peritoneal seeding metastasis. Multiple bone metastases throughout the body. Multiple muscle metastases throughout the body. Large amounts of abdominal and pelvic effusions. e. Possible bilateral adrenal metastases.

2. Bilateral emphysema with bullae. Scattered chronic inflammation in the remaining lungs. Calcification of some arterial walls. Anemia.

3. Multiple liver cysts.

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

5. A few ischemic lesions in the deep bilateral brain regions, indicative of age-related brain disorders.

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.
