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.
Symmetrical FDG metabolism was increased in the bilateral lateral pterygoid muscles, SUVmax=5.3.
The thyroid gland was normal in shape and size, with slightly heterogeneous density; FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 4.23.9cm was observed in the right middle lobe of the lung, with lobulated margins; FDG metabolism was increased, SUVmax=8.1.
Several solid micronodules, approximately 0.2-0.4cm in long diameter, with clear borders, were observed in both lungs; FDG metabolism was normal.
A few punctate and linear lesions were also observed in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the bilateral hilar regions, pretracheal spaces, aortic windows, and below the carina; the largest was located in the right hilum, with a short diameter of approximately 1.1cm; FDG metabolism was increased, SUVmax=4.5.
Cardiac imaging: No abnormalities observed.
Calcification of some arterial walls (including coronary arteries).
Esophageal dilation, wall thickening, or masses were not observed; FDG uptake was not increased.
Liver morphology and size: No obvious abnormalities were observed; liver margins were smooth; hepatic fissures were not widened; no obvious abnormal density shadows were observed in the liver parenchyma on plain CT scan; FDG uptake was not abnormal.
Main portal vein showed no obvious widening; intrahepatic and extrahepatic bile ducts were not dilated.
Gallbladder morphology and size: No abnormalities were observed; gallbladder wall thickening was not observed; local FDG uptake was not abnormal.
Pancreas morphology: Normal; no obvious abnormal density shadows were observed in the parenchyma; main pancreatic duct was not widened; FDG uptake was not significantly abnormal.
Spleen morphology, size, density, and FDG uptake were not abnormal.
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 normal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly filled, with no obvious thickening of the stomach wall, and FDG uptake is normal.
The intestines are poorly filled, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
The prostate is normal in shape and size, with uniform density, and no abnormal FDG metabolism is seen.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious effusion is seen in the abdominal or pelvic cavities.
The L4 vertebral body is slightly displaced anteriorly, and the L5 vertebral body is slightly displaced posteriorly.
Osteophyte formation is present at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulges are observed.
Multiple areas showed decreased density in the muscles of the left upper arm, left erector spinae, right gluteal muscles, right pectineus, left obturator internus, multiple muscles of the right calf, and muscles between the 1st and 2nd metacarpal bones of both hands, with increased FDG metabolism (SUVmax=3.3); and increased FDG metabolism in the strip-like areas of the right sole (SUVmax=2.5).

Impression

1. a. A mass in the right middle lobe of the lung with increased FDG metabolism, suggestive of lung cancer. b. Multiple muscle metastases throughout the body (see description for details); linear FDG increase in the right plantar fossa, suggesting possible tonic uptake; please correlate with clinical findings and follow up. c. Right hilar lymph node metastasis. Left hilar and mediastinal lymph node metastasis to be ruled out.

2. Symmetrical increased FDG metabolism in the bilateral lateral pterygoid muscles, suggestive of tonic uptake.

3. Several small, solid, chronic inflammatory nodules in both lungs. Minor chronic inflammation and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

4. Mild anterior slippage of the L4 vertebral body and mild posterior slippage of the L5 vertebral body. 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.
