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 bilaterally, with no obvious abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, 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 palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A soft tissue mass measuring approximately 3.6*2.3*5.1cm was observed in the posterior segment of the left lower lobe, closely adjacent to the descending aorta; FDG metabolism was increased, with SUVmax = 8.9.
Mixed ground-glass nodules with clear borders were observed in the apical-posterior segment, anterior segment of the left upper lobe, and posterior segment of the left lower lobe; their long diameters were approximately 0.8cm, 0.5cm, and 0.7cm, respectively; FDG uptake was normal.
Multiple solid nodules with clear borders were observed in the right lower lobe and left lung; their long diameters were approximately 0.3-0.8cm; FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Several lymph nodes were observed in the left hilum, the largest being approximately 1.0 cm in short diameter, with increased FDG metabolism and an SUVmax of 3.5.
The cardiac silhouette appeared normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissures.
FDG metabolism in the liver parenchyma was somewhat uneven.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder's shape and size were normal, with multiple punctate and annular dense shadows within it, the largest being approximately 1.6 cm in long diameter.
The gallbladder wall showed no thickening, and localized FDG uptake was normal.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size.
A low-density lesion of approximately 0.6 cm in diameter was seen in the right kidney, with clear borders and absent FDG uptake.
The renal pelvis, calyces, and ureter were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
Stomach distension was poor, but the stomach wall was not significantly thickened, and FDG uptake was not significantly abnormal.
Intestinal distension was poor, but the intestinal wall was not significantly thickened or lumped, and FDG uptake was physiological.
The prostate was normal in shape and size, with uniform density, and no abnormal FDG metabolism was observed.
The bladder was generally full, and no obvious positive stones were seen.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
Nuchal ligament calcification was observed.
The spinal alignment is normal, with a dense shadow seen within the L1 vertebral body.
Osteophyte formation is present at the marginal borders of some vertebral bodies.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass located adjacent to the descending aorta in the posterior segment of the left lower lobe, with increased FDG metabolism, consistent with lung cancer. Left hilar lymph node metastasis is possible; please correlate with clinicopathology. b. Mixed ground-glass nodules in the apical and posterior segments of the left upper lobe and the posterior segment of the left lower lobe, with normal FDG uptake, suggest atypical adenomatous hyperplasia or chronic inflammatory nodules; please monitor with CT. c. Multiple solid nodules in the right lower lobe and left lung, with normal FDG uptake, highly suggestive of chronic inflammatory nodules; metastasis needs to be ruled out; please monitor with CT. d. Calcification of some arterial walls (including coronary arteries).

2. Uneven FDG metabolism in the liver parenchyma; contrast-enhanced MRI is recommended to rule out metastasis.

3. Multiple gallstones. Small cyst in the right kidney.

4. Spinal degenerative changes. Postoperative changes following L1 vertebral fracture.

5. A few ischemic lesions in the deep bilateral brain regions; age-related brain damage. MRI is recommended.

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.
