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 not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious abnormalities.
The maxillary sinus mucosa was slightly thickened bilaterally, but the sinus walls were intact.
FDG metabolism was increased around the left maxillary dentition (SUVmax = 5.9).
The nasopharyngeal wall was not thickened, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were 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.
No abnormalities were observed in the morphology and structure of the laryngopharynx.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular solid mass measuring approximately 3.2 2.8 cm was observed in the apical segment of the right upper lobe, with lobulated and spiculated margins, locally adhered to the pleura, and showing increased FDG metabolism (SUVmax = 5.9).
Multiple scattered punctate lesions, patchy lesions, and flocculent opacities were observed in the anterior segment of the right upper lobe, with slightly increased FDG metabolism (SUVmax = 2.0).
A small ground-glass nodule was observed in the right middle lobe, with a CT value of approximately -590 HU, a long diameter of approximately 0.3 cm, relatively clear borders, and no abnormalities in FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Several small lymph nodes were seen in the right hilum, pretracheal space, and aortic window, the largest with a short diameter of approximately 0.8 cm.
FDG metabolism was increased, with SUVmax = 3.5.
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and 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's shape and size were normal, with slight thickening of the gallbladder wall and increased density in the cavity; FDG uptake was normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen's shape, size, density, and FDG uptake are normal.
Cystic lesions are seen in both kidneys, the largest being approximately 1.4 cm in long diameter, located in the left kidney.
FDG uptake is absent.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with continuous FDG metabolism increased in parts of the colon and rectum (SUVmax = 4.5).
The prostate is full in shape, approximately 5.1 cm in transverse diameter, with punctate calcifications inside; FDG metabolism is normal.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging.
Punctate bony dense shadows were observed in both iliac bones; FDG metabolism was normal.

Impression

1. a. Space-occupying lesion in the apical segment of the right upper lobe, with increased FDG metabolism, suggestive of lung cancer; please correlate with clinicopathology. b. Reactive hyperplasia of the right hilar and mediastinal lymph nodes; follow-up is recommended. c. Inflammation in the right upper lobe; ground-glass nodule in the right middle lobe, with normal FDG metabolism, suggestive of inflammatory nodules or atypical adenomatous hyperplasia; annual HRCT follow-up is recommended. d. Calcification of some arterial walls (including coronary arteries).

2. Chronic cholecystitis. Cholecystic stasis.

3. Bilateral renal cysts. Benign prostatic hyperplasia with calcification.

4. Continuous increased FDG metabolism in parts of the colon and rectum, suggestive of inflammatory or physiological uptake; colonoscopy follow-up is recommended.

5. Degenerative changes in the spine. L4/5 and L5/S1 disc bulges. Bilateral iliac bone islands.

6. A few deep cerebral ischemic lesions bilaterally, indicative of age-related cerebral insufficiency. Bilateral chronic maxillary sinusitis. Inflammation around the left maxillary dentition; specialist examination 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.
