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 not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
The ethmoid sinus mucosa was thickened bilaterally, but the sinus walls were intact.
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 structurally normal, and the bilateral parapharyngeal spaces were clear, with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
Several slightly high-density nodules were seen bilaterally in the parotid glands, the largest with a short diameter of approximately 1.0 cm, showing increased FDG metabolism (SUVmax = 15.5).
No abnormal density shadows were seen in the bilateral submandibular glands.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes are seen bilaterally in the neck, and FDG metabolism is normal.
An irregular mass measuring approximately 5.6 3.5 cm is seen in the right middle lobe, closely adhering to the horizontal fissure, with lobulated and spiculated margins, and increased FDG metabolism (SUVmax = 17.7).
The lesion involves the right upper lobe.
Several solid micronodules, approximately 0.2-0.3 cm in long diameter, with clear borders, are seen in both lungs, and FDG metabolism is normal.
A few linear and punctate lesions are also seen in both lungs, and FDG metabolism is normal.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax bilaterally.
A slightly enlarged lymph node, approximately 1.0 cm in short diameter, is seen in the right hilum, with increased FDG metabolism (SUVmax = 3.2).
The cardiomegaly is present.
After atrial fibrillation ablation, a dense metallic shadow is seen within the cardiomegaly, and FDG metabolism is normal.
Calcification is present in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, thickening or masses in the esophageal wall, and no increased FDG uptake.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissures; multiple cystic lesions were observed within the liver, the largest being approximately 1.0 cm in length, with absent FDG uptake.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with slight thickening of the antral wall, and no abnormal FDG metabolism was observed.
The intestinal tract was not sufficiently full, with increased continuous FDG metabolism in the descending colon, sigmoid colon, and rectum (SUVmax = 14.1).
An air-filled cavity was observed in the descending duodenum, but FDG metabolism was normal.
The prostate was of normal size and uniform density, with no abnormally increased FDG uptake.
The bladder was adequately full, with no obvious positive stones.
There was a large amount of fluid in the tunica vaginalis of the right testis.
No enlarged lymph nodes were seen 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 spinal alignment was normal, with some vertebral margin osteophyte formation and L4/5 and L5/S1 intervertebral disc bulging, but FDG uptake was normal.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. A mass in the right middle lobe of the lung, involving the right upper lobe, with increased FDG metabolism, suggestive of lung cancer. Possible right hilar lymph node metastasis. b. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammations and old lesions in both lungs. c. Post-ablation changes after atrial fibrillation; enlarged cardiac silhouette. Calcification of some arterial walls (including coronary arteries).

2. Multiple liver cysts. A small diverticulum in the descending duodenum.

3. Continuous increased FDG metabolism in the descending colon, sigmoid colon, and rectum, suggestive of inflammatory or physiological uptake.

4. Large amount of hydrocele in the right testis.

5. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

6. A few ischemic lesions in the deep bilateral brain regions, suggestive of age-related brain changes. Chronic inflammation of both ethmoid sinuses.

7. Several slightly high-density nodules in both parotid glands, with increased FDG metabolism, suggestive of adenolymphoma; 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.
