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: The brain morphology and structure were normal; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and without significant 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 not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
Thyroid gland: Normal in shape and size, with slightly uneven density; FDG uptake not abnormal.
Multiple small lymph nodes in bilateral deep cervical spaces and bilateral submandibular regions, the largest with a short diameter of approximately 0.5 cm; FDG metabolism slightly increased, SUVmax = 2.1.
Multiple irregular soft tissue shadows in the right hilum, containing multiple calcifications; stenosis of the posterior segmental bronchus of the lower lobe and part of the basal segmental bronchus; compression changes in the middle lobe bronchus; lesion range approximately 5.7*2.8*7.8 cm; CT value approximately 43 HU; FDG metabolism increased, SUVmax = 11.9.
Multiple punctate, patchy, nodular, and linear shadows in the right lung; FDG metabolism slightly increased, SUVmax = 1.4.
Thickening of the right oblique fissure pleura.
Small amount of right pleural effusion.
Multiple lymph nodes were observed in the right hilum, right supraclavicular fossa, anterior to the superior vena cava, pretracheal space, aortic window, and below the carina, the largest being approximately 0.8 cm in short diameter.
FDG metabolism was increased, with SUVmax = 6.8.
The cardiac silhouette was normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed decreased liver parenchymal density (CT value approximately 39 HU), and no abnormal FDG uptake.
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 no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with multiple low-density lesions in both kidneys, well-defined borders, and absent FDG uptake; the largest lesion was located in the right kidney, approximately 2.2 cm in diameter.
No widening of the renal pelvis, calyces, or ureters was observed, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
Stomach distension was poor, with no significant thickening of the gastric wall, and FDG uptake was not significantly abnormal.
Intestinal distension was poor, with no significant thickening or mass in the intestinal wall; FDG uptake was physiological.
Prostate morphology and size were normal, with a cystic low-density lesion approximately 0.5 cm in long diameter inside; no abnormal FDG metabolism was observed.
Bladder distension was normal, with no obvious positive stones.
Bilateral hydrocele was present.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdomen or pelvis.
Pelvic calcifications were present.
Nuchal ligament calcification was also present.
The spinal alignment was normal, with some vertebral body margin osteophytes.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass in the right hilum with elevated FDG metabolism, stenosis of the posterior segment of the lower lobe bronchus and part of the basal segment bronchus, strongly suggestive of lung cancer, atypical infection to be ruled out; b. High probability of metastasis to the right hilar, mediastinal, and right supraclavicular fossa lymph nodes; inflammatory lymph nodes to be ruled out. Reactive hyperplasia of bilateral deep cervical spaces and bilateral submandibular lymph nodes. c. Obstructive pneumonia in the right lung. Thickening of the right oblique fissure pleura. Small amount of pleural effusion in the right pleural cavity.

2. Fatty liver. Bilateral renal cysts. Pelvic calcifications. Prostatic cysts. Bilateral hydrocele.

3. Spinal degenerative changes.

4. No obvious abnormalities seen on cranial scintigraphy.

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.
