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 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, with symmetrical bilateral ventricles and 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.
The laryngopharynx showed no abnormalities in morphology or structure.
The parotid and submandibular glands showed no abnormal density shadows bilaterally.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No enlarged lymph nodes were seen bilaterally in the neck, and FDG metabolism was normal.
The chest is asymmetrical.
An irregular mass measuring approximately 8.1 6.1 7.0 cm is seen in the lower lobe of the right lung, with elevated FDG metabolism (SUVmax = 13.9), surrounded by patchy shadows.
Stenosis and occlusion of the right lower lobe bronchus are also observed.
Multiple solid nodules, approximately 0.2-0.6 cm in long diameter, with clear borders, are seen in both other lungs, with normal FDG metabolism.
Several solid nodules are seen in the right interlobar pleura, the largest approximately 0.5 cm in long diameter, with normal FDG metabolism.
A few linear and punctate lesions are also seen in both lungs, with normal FDG metabolism.
A small amount of pleural effusion is present on the right side.
Multiple enlarged lymph nodes are seen in the right hilum, superior mediastinum, pretracheal space, aortic window, and below the carina, the largest approximately 1.2 cm in short diameter, with elevated FDG metabolism (SUVmax = 4.5).
Some arterial walls show calcification.
The esophagus showed no dilation, wall thickening, or mass; FDG uptake was not increased.
The liver had an irregular outline with multiple cystic lesions, the largest approximately 2.5 cm in length, and FDG uptake was absent.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
Several lymph nodes were seen in the right prediaphragmatic group, the largest approximately 0.8 cm in short diameter, with slightly increased FDG metabolism (SUVmax = 2.3).
The gallbladder was normal in shape and size, with no wall thickening and increased intraluminal density; 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; FDG uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with cystic low-density lesions in both kidneys, the largest approximately 1.1 cm in length; a small nodular dense shadow was also seen in the left renal parenchyma; FDG uptake was normal.
No widening of the renal pelvis, calyces, or ureter was observed, and FDG uptake showed no significant abnormalities.
Bilateral adrenal gland imaging showed no significant abnormalities.
Gastric distension was poor, but the gastric wall showed no significant thickening, and FDG uptake showed no significant abnormalities.
Intestinal distension was poor, but the intestinal wall showed no significant thickening or mass, and FDG uptake was physiological.
The prostate was of normal size and uniform density, and FDG uptake showed no abnormal increase.
The bladder was generally full, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism showed no abnormalities.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Mild anterior displacement of the L4 vertebral body was observed, along with scoliosis, osteophyte formation at some vertebral margins, and L4/5 and L5/S1 intervertebral disc bulging, but FDG uptake showed no abnormalities.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. A mass in the lower lobe of the right lung, with elevated FDG metabolism, suggestive of lung cancer with obstructive changes. Bilateral lung metastases. Extensive metastasis to the right interlobar pleura. Small amount of pleural effusion on the right side. b. Metastasis to lymph nodes in the right hilum and mediastinum. Possible metastasis to the right anterior diaphragmatic lymph nodes. c. Scattered chronic inflammation and old lesions in both lungs. Asymmetrical chest wall. Calcification of some arterial walls.

2. Multiple cysts in the liver. Contrast agent residue in the gallbladder. Bilateral renal cysts, calcification in the left kidney.

3. Mild anterior slippage of the L4 vertebral body. Scoliosis. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

4. A few ischemic lesions in the deep bilateral brain regions, age-related brain changes.

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.
