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 few punctate low-density shadows were observed in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 3.4 2.9 cm was seen in the posterior basal segment of the right lower lobe, with deeply lobulated margins; FDG metabolism was increased, SUVmax = 13.9; diffuse reticular shadows were seen in both lungs; FDG metabolism was increased, SUVmax = 3.6.
The pleura was slightly thickened bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were seen in the right hilum, pretracheal space, aortic window, subcarinal region, and right supraclavicular fossa; the largest was located in the right hilum, with a short diameter of approximately 2.4 cm; FDG metabolism was increased, SUVmax = 16.0.
The cardiac silhouette was normal.
Calcification of some arterial walls was observed (including the coronary arteries).
No esophageal dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
No obvious abnormalities were observed in the shape and size of the liver; the liver margins were smooth, and the hepatic fissures were not widened.
A low-density nodule was observed in the left lateral lobe and right posterior lobe of the liver; the former was slightly larger, approximately 1.7 1.5 cm, with clear borders and increased FDG metabolism (SUVmax = 9.5).
Multiple cystic lesions were observed within the liver, the largest with a long diameter of approximately 0.8 cm, and FDG uptake was absent.
No significant widening of the main portal vein was observed, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
No abnormalities were observed in the shape and size of the gallbladder; the gallbladder wall was not thickened, and local FDG uptake was not abnormal.
The pancreas was normal in shape; no obvious abnormal density shadows were observed in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
Spleen morphology, size, density, and FDG uptake were normal.
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 not significantly abnormal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
Stomach distension was poor, with no obvious thickening of the stomach wall, and FDG uptake was not significantly abnormal.
Continuous FDG metabolism was increased in parts of the colon and rectum, SUVmax=5.6.
The prostate was normal in shape and size, with uniform density, and no abnormal FDG metabolism was observed.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious effusion was seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
Nuchal ligament calcification is present.
Bone destruction is observed in the T2 spinous process, with increased FDG metabolism and an SUVmax of 5.8.

Impression

1. a. Space-occupying lesion in the posterior basal segment of the right lower lobe, with increased FDG metabolism, suggestive of peripheral lung cancer. Multiple lymph node metastases in the right hilum, mediastinum, and right supraclavicular fossa. Liver metastases. T2 spinous process metastases. b. Interstitial pneumonia in both lungs. Slight pleural thickening bilaterally. Calcification of some arterial walls (including coronary arteries).

2. A few ischemic lesions in the deep bilateral brain.

3. Multiple liver cysts.

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

5. Spinal degenerative changes. L4/5 and L5/S1 intervertebral disc bulges.

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.
