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, with no obvious abnormalities.
The mucosa of the bilateral maxillary and ethmoid sinuses was thickened, but the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, 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 bilateral palatine tonsils showed physiological uptake.
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 uniform density, and no abnormalities were observed in FDG uptake.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Increased translucency of both lungs, accompanied by multiple air-filled cavities; an irregular mass measuring approximately 3.1 2.0 cm was observed in the posterior segment of the right lower lobe, with increased FDG metabolism (SUVmax = 10.5); several solid micronodules were observed in both lungs, with a long diameter of approximately 0.2?.3 cm, clear borders, and no abnormalities in FDG metabolism.
Reticular hazy shadows were observed in the subpleural region of both lower lobes, with no abnormalities in FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Several lymph nodes were observed in the bilateral hilar regions, pretracheal spaces, para-aortic arch, aortopulmonary window, and subcarinal region, the largest with a short diameter of approximately 0.8 cm, showing increased FDG metabolism (SUVmax = 3.2).
Calcification of some arterial walls (including coronary arteries).
No esophageal dilation, wall thickening, or masses were observed; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth, and the hepatic fissures were not widened.
Multiple cystic lesions were observed within the liver, the largest being approximately 1.0 cm in length, with absent FDG uptake.
The main portal vein showed no significant widening; no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size; the gallbladder wall was not thickened; localized FDG uptake was normal.
The pancreas was normal in shape; no significant abnormal density shadows were observed in the parenchyma; the main pancreatic duct was not widened; FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
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 not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly filled, with slight thickening of the walls in part of the gastric body and antrum, and slightly increased FDG uptake (SUVmax = 2.5).
The intestines are poorly filled, with increased FDG metabolism in some parts of the intestines (SUVmax = 4.2).
The prostate is full in shape, with a transverse diameter of approximately 5.0 cm, and punctate calcifications are seen 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, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass in the posterior segment of the right lower lobe, with increased FDG metabolism, strongly suggestive of lung cancer; please correlate with clinicopathology. b. Several small, solid, chronic inflammatory nodules in both lungs are highly probable; follow-up CT scan is recommended. Interstitial inflammation and old lesions in both lower lobes. Alveolar emphysema and bullous formation in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes is highly probable; follow-up examination is recommended. Calcification of some arterial walls (including coronary arteries).

2. Multiple cysts in the liver.

3. Slight thickening of the walls of part of the gastric body and antrum, with mildly increased FDG uptake, suggestive of chronic gastritis; increased FDG metabolism in part of the intestines, suggestive of inflammatory or physiological uptake. Follow-up gastroscopy and colonoscopy are recommended for all of the above.

4. Benign prostatic hyperplasia with calcification.

5. Cervical, thoracic, and lumbar spondylosis; L4/5 and L5/S1 intervertebral disc bulge.

6. A few ischemic lesions in the deep bilateral cerebral regions; senile encephalopathy. 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.
