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 slightly high-density nodule, approximately 1.0 1.2 cm in size, was seen in the left centrum semiovale, surrounded by edema.
FDG metabolism was increased, with SUVmax = 7.2.
No widening of the ventricles, sulci, fissures, or cisterns was observed.
The ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
Cystic lesions were seen in both maxillary sinuses, with intact sinus walls.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, and there was 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.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen 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 slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass, approximately 7.5 5.3 cm in size, was seen near the hilum of the left upper lobe, fused with a left hilar lymph node; the margins showed lobulation and spiculation; FDG metabolism was increased (SUVmax = 12.3).
A bronchial stenosis/occlusion was observed in the left upper lobe, surrounded by patchy and flocculent areas of increased density; FDG metabolism was increased (SUVmax = 3.5).
Several small solid nodules were observed in both lungs, approximately 0.2?.4 cm in long diameter, with clear borders; FDG metabolism was normal.
A few punctate and linear lesions were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally; there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the mediastinum.
The cardiac silhouette was normal.
The esophagus showed no dilation, and the esophageal wall was not significantly thickened or swollen.
FDG uptake was not increased.
The liver showed no obvious abnormalities in shape or size, with smooth borders and no widening of the hepatic fissures.
Punctate calcifications were observed in the right lobe of the liver; no other abnormal density shadows were seen in the liver parenchyma, and 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, and the gallbladder wall was not thickened.
Local FDG uptake was normal.
The pancreas was normal in shape, with no obvious 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, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor, with no obvious thickening of the gastric wall and no obvious abnormalities in FDG uptake.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate was normal in size and shape, with punctate calcifications and no abnormal FDG metabolism.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No obvious fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass near the hilum of the left upper lobe, fused with the left hilar lymph node, with increased FDG metabolism, suggestive of central lung cancer with hilar lymph node metastasis and obstructive inflammation of the left upper lobe. b. A slightly high-density nodule in the left centrum semiovale, surrounded by edema, with increased FDG metabolism, suggestive of brain metastasis.

2. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammations and old lesions in both lungs.

3. Calcifications in the liver.

4. Calcifications in the prostate.

5. Osteophyte formation in the cervical, thoracic, and lumbar vertebrae; L4/5 and L5/S1 intervertebral disc bulges.

6. Small submucosal cysts in both maxillary 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.
