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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: a nodular high-density shadow measuring approximately 0.9*0.6cm in the sellar region, with no significant abnormalities in FDG uptake.
A few punctate low-density shadows were observed in the deep bilateral cerebral regions.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both 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 normal.
The bilateral pharyngeal recesses were symmetrical, 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 bilateral palatine tonsils showed physiological uptake.
The laryngopharynx showed no abnormalities in morphology or structure.
The bilateral parotid and submandibular glands showed no abnormal density shadows.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No enlarged lymph nodes were observed bilaterally in the neck, and FDG metabolism was normal.
An irregular nodule measuring approximately 2.9 1.6 cm was observed in the anterior segment of the right upper lobe, with lobulated and spiculated margins, and increased FDG metabolism (SUVmax = 9.0).
Multiple solid small nodules were observed in both lungs, the largest being approximately 0.8 cm in long diameter in the lateral basal segment of the left lower lobe, with clear borders and normal FDG metabolism.
Reticular hazy shadows were observed in both lower lobes, and FDG metabolism was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Several lymph nodes were observed in the right hilum, below the tracheal carina, and bilateral axillae, the largest being approximately 1.0 cm in short diameter, with increased FDG metabolism (SUVmax = 3.6).
The cardiac silhouette was normal.
Calcification of some arterial walls (including coronary arteries) was observed.
No esophageal dilation was observed, and no significant thickening or mass was observed in the esophagus; FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissures.
Calcifications were observed in the left lobe of the liver, and FDG uptake was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape and size, with a slightly roughened wall and increased density within the gallbladder; local 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, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Accessory splenic nodules were observed around the spleen.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no obvious thickening of the gastric wall; FDG uptake was normal.
The intestinal tract was not sufficiently full, with continuous FDG metabolism elevated in the ascending colon, descending colon, sigmoid colon, and rectum (SUVmax = 6.2).
FDG metabolism was also elevated at the anal orifice (SUVmax = 9.3).
The prostate was well-formed with punctate calcifications, but FDG uptake was not abnormally elevated.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region, and FDG metabolism was normal.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The L3 and L5 vertebral bodies were slightly displaced posteriorly, with some vertebral margin osteophytes, L3/5 intervertebral disc bulging, and L2/3 and L4/5 intervertebral disc accretion.
Calcification of the nuchal ligament was present.
Multiple areas of elevated FDG metabolism were observed around the left elbow, both knees, both ankles, and the small joints of both hands and feet (SUVmax = 6.4).

Impression

1. a. Irregular nodules in the anterior segment of the right upper lobe, with increased FDG metabolism, suggestive of lung cancer; please correlate with clinicopathology. b. Right hilar and subcarinal lymph node metastasis to be ruled out; bilateral axillary lymph node reactive hyperplasia is highly probable; close follow-up is recommended. c. Multiple solid nodules in both lungs with normal FDG metabolism, highly probable as chronic inflammatory nodules; regular CT scans are recommended to rule out other complications. Interstitial inflammation in the lower lobes of both lungs. Calcification of some arterial walls (including coronary arteries).

2. Liver calcifications. Chronic cholecystitis, cholestasis or sludge-like stones in the gallbladder. Benign prostatic hyperplasia.

3. Continuous increased FDG metabolism in the ascending colon, descending colon, sigmoid colon, and rectum, suggestive of inflammatory lesions; colonoscopy is recommended. Hemorrhoidal changes.

4. Degenerative changes in the spine. Lumbar instability. L3/5 disc bulge, L2/3 and L4/5 disc pneumatosis and degeneration.

5. Increased FDG metabolism around the left elbow, both knees, both ankles, and small joints of both hands and feet, suggesting inflammatory changes. A mass in the sellar region is suspected, possibly a pituitary tumor. There are a few ischemic lesions in the deep bilateral brain regions, indicative of age-related brain conditions. Further enhanced 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.
