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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
The maxillary sinus mucosa was thickened bilaterally, but the sinus walls were intact.
The nasopharyngeal wall was not thickened; FDG uptake was normal; the pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A soft tissue mass measuring approximately 5.6*4.5*9.0cm is seen near the hilum of the left lower lobe, adjacent to the spine, with local bronchial obstruction.
FDG metabolism is elevated, with an SUVmax of 6.0.
Multiple reticular opacities are seen in both lungs, with mildly elevated FDG metabolism and an SUVmax of 1.8.
Bullae are present in both lower lobes.
Pleural thickening is present bilaterally, but there is no pleural effusion or pneumothorax.
Multiple lymph nodes are seen in the right hilum, paratracheal region, aortic arch, and below the carina, the largest being approximately 0.8cm in short diameter.
Some have elevated FDG metabolism, with an SUVmax of 5.1.
Multiple calcifications are present in the right hilum.
Some arterial walls are calcified.
The cardiac silhouette is normal.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
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 a punctate dense shadow seen in the right kidney.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no obvious thickening of the stomach wall and no obvious abnormal FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
The prostate was normal in size and density, with no abnormally increased FDG uptake.
The bladder is generally full, with no obvious positive stones.
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.
Calcification of the nuchal ligament was observed.
The spinal alignment was normal, with some vertebral body margin osteophytes.
No abnormal FDG metabolism was observed in the entire skeleton.

Impression

1. a. Mass in the lower lobe of the left lung, with increased FDG metabolism, consistent with lung cancer. b. Multiple lymph nodes in the right hilum and mediastinum with some showing increased FDG metabolism, suggesting possible reactive lymph node hyperplasia; partial metastasis is pending. Please compare with previous scans for follow-up. c. Interstitial lung inflammation in both lungs. Bullae in the lower lobes of both lungs. Pleural thickening bilaterally. Multiple calcifications in the right hilum. Calcification of some arterial walls.

2. Small kidney stone in the right kidney.

3. Degenerative changes in the spine.

4. No obvious abnormalities seen on cranial scintigraphy. Bilateral maxillary sinusitis.

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.
