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, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and no abnormalities in FDG uptake were observed.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
Two dense nodules were observed on the right palatine tonsil, with a long diameter of approximately 0.4 cm; both palatine tonsils showed physiological uptake.
No abnormal density shadows were observed 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, but its density is somewhat uneven.
FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
The lung markings are clear.
An irregular nodular or mass-like soft tissue density shadow is present in the anterior segment of the left upper lobe, with indistinct borders and uneven density.
The largest cross-sectional size is approximately 8.5*2.7cm.
FDG uptake is unevenly increased, with SUVmax=10.9.
Adjacent pleural thickening is present.
The bronchus in the anterior segment of the left upper lobe is truncated.
Several ground-glass nodules and solid nodules are present in both lungs, the largest being approximately 0.4cm in diameter.
FDG uptake is normal.
A few small punctate or linear lesions are present in both lungs, with normal FDG uptake.
Right pleural thickening is not seen.
There is no pleural effusion or pneumothorax bilaterally.
A cystic shadow containing air is seen at the right posterior margin of the upper trachea.
Multiple lymph nodes were observed in the pretracheal space, para-aortic arch, aortic window, and below the carina, the largest measuring approximately 0.8 cm in short diameter, with increased FDG uptake (SUVmax = 3.9).
The cardiac silhouette was normal.
Partial arteriosclerosis was observed.
The esophagus showed no dilation, wall thickening, or masses, and FDG uptake was normal.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Several cystic lesions were present within the liver, the largest approximately 2.6 cm in diameter, with normal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder was absent following cholecystectomy.
The pancreas was normal in shape, with no obvious 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 punctate dense shadows in the right renal calyx and a small cystic lesion in the left renal parenchyma, approximately 0.9 cm in diameter.
FDG metabolism was normal.
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 slight thickening of the antral wall and mildly increased FDG uptake (SUVmax = 2.1).
Intestinal distension was unsatisfactory, with physiological uptake.
The prostate was enlarged, with a long diameter of approximately 6.0 cm, containing dense nodules.
FDG uptake was not abnormally increased.
A small amount of hydrocele was observed in the left testis.
Bladder distension was poor, with no obvious positive stones.
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.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Focal FDG uptake was observed around the right ischial tuberosity, with an SUVmax of 3.0.
A subcutaneous fat density shadow measuring approximately 2.5*1.2cm was observed in the right anterior chest wall; FDG metabolism was normal.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. A mass in the anterior segment of the left upper lobe with increased FDG metabolism, suggestive of lung cancer with obstructive changes; please correlate with clinicopathology. Reactive hyperplasia of mediastinal lymph nodes is highly probable, but mixed metastasis needs to be ruled out. b. Chronic inflammatory micronodules or atypical adenomatous hyperplasia in both lungs; annual HRCT follow-up is recommended. A few post-inflammatory lesions in both lungs. Tracheal diverticulum. Calcification of some arterial walls (including coronary arteries).

2. Liver cyst. Post-cholecystectomy changes.

3. Right kidney stone. Small cyst in the left kidney. Benign prostatic hyperplasia with calcification. Small amount of hydrocele in the left testis.

4. Chronic inflammatory changes in the gastric antrum; please correlate with endoscopic follow-up.

5. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulges. Right ischial tuberosity inflammation. Lipoma on the right anterior chest wall.

6. No obvious abnormalities were found on cranial scintigraphy. Calcification lesion in the right palatine tonsil.

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.
