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, and 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, and no obvious abnormalities were seen.
A cystic lesion was seen in the left maxillary sinus; there was slight mucosal thickening in the bilateral ethmoid sinuses and the right maxillary sinus, but the sinus walls were intact.
No thickening was seen in the nasopharyngeal wall; FDG uptake was normal; the bilateral pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
FDG metabolism was increased in the bilateral palatine tonsils and oropharynx, with SUVmax = 5.9.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size, with uniform density; FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 3.6 2.7 cm is seen in the right middle lobe of the lung, with lobulated and spiculated margins; FDG metabolism is increased, SUVmax = 13.7.
Several solid nodules, approximately 0.2?.5 cm in long diameter, with clear borders, are seen in both lungs; FDG metabolism is normal.
A few speckled and linear lesions are also seen in both lungs; FDG metabolism is normal.
No pleural thickening is seen bilaterally; there is no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
Some arterial walls show calcification.
The esophagus is not dilated; the esophageal wall is not significantly thickened or swollen; FDG uptake is normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormal 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 abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
The left adrenal gland was slightly enlarged, but FDG metabolism was normal.
The right adrenal gland showed no obvious abnormalities on contrast.
Stomach distension is poor, with no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal distension is poor, with increased FDG metabolism in some intestinal segments, SUVmax=4.3 (considered physiological uptake).
Prostate shape and size are normal, with punctate calcifications seen, and no abnormal FDG metabolism.
Bladder distension is normal, with no obvious positive stones seen.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.
Post-cervical internal fixation surgery, no abnormal FDG metabolism was seen in the surgical area.
Localized increased bone density in the right 6th rib, with no abnormalities in FDG metabolism.

Impression

1. a. Right middle lobe lung mass with elevated FDG metabolism, suggestive of lung cancer; please correlate with clinicopathology. b. Several small, solid, chronic inflammatory nodules in both lungs are highly probable; annual CT scan recommended. Minor chronic inflammation and old lesions in both lungs. Some arterial wall calcification. c. Left adrenal hyperplasia is highly probable; follow-up CT scan recommended to rule out metastasis.

2. Prostatic calcification.

3. Cervical, thoracic, and lumbar spondylosis. L4/5 and L5/S1 intervertebral disc bulge. Post-cervical spine surgery changes.

4. Minor ischemic lesions in the deep bilateral brain, age-related encephalopathy. Chronic inflammation of bilateral palatine tonsils and oropharynx. Submucosal cyst of the left maxillary sinus. Minor chronic inflammation of bilateral ethmoid sinuses and the right maxillary sinus.

5. Benign osteopathy of the 6th rib on the right side.

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.
