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: Normal brain morphology and structure; low-density fluid and slightly high-density shadows were seen in the subcranial region of the right frontal lobe; punctate slightly low-density shadows were seen in the deep brain; FDG metabolism was normal.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Bilateral eyeballs were symmetrical and without obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed; the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The bilateral parotid and submandibular glands were normal in morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
Both lungs show clear lung markings.
An irregular mass is observed in the posterior segment of the left upper lobe, with a maximum cross-section of approximately 3.0*1.9cm.
FDG uptake is increased (SUVmax=10.7), and the boundary with the adjacent enlarged hilar lymph nodes is indistinct.
Several small solid nodules are present in the upper lobes of both lungs and the left lower lobe, the largest being approximately 0.5cm in diameter in the posterior segment of the left upper lobe, with slightly increased FDG uptake (SUVmax=2.4).
Multiple air-filled cavitation shadows are present in the subpleural region of both upper lobes.
Scattered linear lesions are present in both lungs, with normal FDG uptake.
Multiple enlarged lymph nodes are visible in the left hilum, pretracheal vena cava, aortic window, and para-aortic arch, some of which are fused.
The largest is located in the aortic window, with a short diameter of approximately 4.3cm, and increased FDG uptake (SUVmax=11.1).
The left pleura is slightly thickened.
The cardiac silhouette is normal.
Calcification of some arterial walls (including coronary arteries) is present.
Bilateral carotid artery stenting has been performed.
The esophagus showed no dilation, thickening, or mass in the esophageal wall, and no increased FDG uptake.
The liver was normal in shape and size, with smooth borders, no widening of the hepatic fissure, and no abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was absent, but a dense nodule with a long diameter of approximately 1.0 cm was observed in the common bile duct.
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 was normal in shape, size, density, and FDG uptake.
A soft tissue density nodule adjacent to the spleen, approximately 1.5 cm in diameter, was observed; FDG uptake was normal.
Both kidneys were normal in shape and size; several cystic lesions were observed in the parenchyma of the left kidney, the largest approximately 1.2 cm in diameter; a cystic lesion was observed in the right renal pelvis, approximately 1.9 cm in long diameter; FDG uptake was absent; no widening was observed in the renal pelvis, calyces, or ureter; FDG uptake was normal.
The left adrenal gland is enlarged with increased FDG uptake (SUVmax = 3.0).
The right adrenal gland showed no obvious abnormalities on contrast imaging.
The stomach is adequately filled, with slight thickening of the gastric wall in the antrum and increased FDG uptake (SUVmax = 4.4).
The intestines are not adequately filled; no masses were observed, and FDG uptake was normal.
The prostate is of normal size, with punctate dense shadows inside; FDG uptake was not abnormally increased.
There is a small amount of hydrocele in both testes, with calcification on the left.
The bladder is poorly filled, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneum.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies; L3/4, L4/5, and L5/S1 intervertebral disc bulges with pneumodegenerative changes.
A high-density nodule, approximately 1.1 cm in diameter, is present in the medullary canal of the right upper humerus, with increased FDG uptake (SUVmax = 3.5).

Impression

1. a. A mass in the posterior segment of the left upper lobe with elevated FDG metabolism, suggestive of lung cancer, most likely small cell lung cancer; multiple lymph node metastases in the left hilum and mediastinum. b. Some solid nodules in the left upper lobe with mildly elevated FDG metabolism, suggestive of metastatic tumors; chronic inflammatory nodules in the right upper lobe and left lower lobe are more likely. Follow-up with CT is recommended. c. Metastatic tumor in the upper right humerus.

2. Emphysema with bullae in both upper lobes. Scattered post-inflammatory lesions in both lungs. Slight thickening of the left pleura. Calcification of some arterial walls (including coronary arteries). Post-bilateral carotid artery stenting.

3. Post-cholecystectomy with common bile duct stones.

4. Left adrenal hyperplasia. Cysts in the left and right renal pelvis. Calcifications in the prostate. Small amount of hydrocele in both testes, with calcification on the left.

5. Chronic inflammatory changes in the gastric antrum.

6. Degenerative changes in the spine, with L3/4, L4/5, and L5/S1 intervertebral disc bulging accompanied by pneumoconiosis and degeneration.

7. Age-related brain abnormalities, with chronic sublaminal effusion and hemorrhage on the right frontoparietal side, and deep lacunar ischemic lesions in the brain; follow-up 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.
