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: Multiple punctate low-density shadows in the bilateral basal ganglia, with no abnormal FDG metabolism.
Enlargement of the ventricles, sulci, fissures, and cisterns was observed, with symmetrical bilateral ventricles and no midline shift.
Bilateral eyeballs were symmetrical and without obvious abnormalities.
Thickening of the mucosa of the bilateral maxillary and ethmoid sinuses was observed, with intact sinus walls.
No thickening of the nasopharyngeal wall was observed, with no abnormal FDG uptake.
The bilateral pharyngeal recesses were symmetrical, with no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 4.03.71.8cm was seen in the anterior segment of the left upper lobe, adjacent to the mediastinum, with spiculated margins and increased FDG metabolism (SUVmax=10.7).
Patchwork shadows were seen distal to the lesion, with increased FDG metabolism (SUVmax=5.9).
Multiple scattered patchy ground-glass opacities, linear opacities, and cord-like opacities were seen in both lungs, with normal FDG metabolism.
Several small solid nodules were seen in both lungs, with a long diameter of approximately 0.2-0.5cm and clear borders; FDG metabolism was normal.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
The esophagus showed no dilation, thickening or masses in the esophageal wall, and no increased FDG uptake.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissures; multiple cystic lesions were observed within the liver, the largest being approximately 0.9 cm in length, with absent FDG uptake.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; several small punctate dense shadows were observed in both renal pelvises, with no obvious abnormalities in FDG uptake.
The left adrenal gland is slightly enlarged with increased FDG metabolism (SUVmax = 3.5); the right adrenal gland shows no obvious abnormalities on contrast imaging.
Partial thickening of the gastric body and antrum walls shows mildly increased FDG uptake (SUVmax = 2.3).
Intestinal distension is unsatisfactory; continuous FDG metabolism is increased in the sigmoid colon and rectum (SUVmax = 4.5).
The prostate is full in shape, approximately 6.0 cm in diameter, with punctate calcifications inside; no abnormal FDG metabolism is observed.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
Several punctate calcifications are seen beside both testes; FDG metabolism is normal.
The spinal alignment is normal, with some vertebral body margins showing osteophyte formation and calcification.
L4/5 and L5/S1 intervertebral disc bulge.
Mild compression and flattening of L1 disc.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Mass in the anterior segment of the left upper lobe, with increased FDG metabolism, suggestive of lung cancer, accompanied by surrounding inflammation. Please correlate with clinicopathology. b. Multiple scattered chronic inflammations in both lungs. Several small chronic inflammatory nodules (solid) in both lungs. Follow-up CT scan recommended. c. Calcification of some arterial walls. Please correlate with coronary CTA. d. Possible left adrenal hyperplasia. Follow-up CT scan recommended.

2. Multiple liver cysts. Small kidney stones in both kidneys.

3. Chronic gastritis. Continuous increased FDG metabolism in the sigmoid colon and rectum, likely due to inflammatory uptake. Colonoscopy recommended.

4. Benign prostatic hyperplasia with calcification; bilateral testicular capsule calcification.

5. Degenerative changes in the spine. Multiple intervertebral disc calcifications in the thoracic and lumbar spine. L4/5 and L5/S1 disc bulges. Mild compression and flattening of L1.

6. A few ischemic foci in the deep bilateral cerebral regions; age-related brain. Chronic inflammation of the bilateral maxillary and ethmoid sinuses.

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.
