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 brain regions; 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 significant abnormalities.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening; FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was not abnormal.
The palatine tonsils showed physiological uptake bilaterally.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was not abnormal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 4.2 3.6 2.6 cm was observed in the anterior segment of the left upper lobe, with lobulated and spiculated margins.
FDG metabolism was elevated, with an SUVmax of 13.9.
The distal bronchus in the anterior segment of the left upper lobe was obstructed, causing pleural traction.
Patchy high-density shadows were observed around the lesion.
Multiple solid nodules and plaque-like lesions were observed in both lungs, with long diameters of approximately 0.2?.5 cm and clear borders.
FDG metabolism was normal.
A few linear shadows and calcifications were observed in both lungs, with normal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the bilateral hilum, beside the left trachea in the superior mediastinum, at the aortic window, and beside the aortic arch.
The largest had a short diameter of approximately 2.0 cm.
FDG metabolism was elevated, with an SUVmax of 7.8.
Cardiac imaging: No abnormalities observed.
Calcification of some arterial walls (including coronary arteries).
Esophageal dilation, wall thickening, or masses were not observed; FDG uptake was not increased.
Liver morphology and size: No obvious abnormalities were observed; liver margins were smooth; hepatic fissures were not widened; no obvious abnormal density shadows were observed in the liver parenchyma on plain CT scan; FDG uptake was not abnormal.
Main portal vein showed no obvious widening; intrahepatic and extrahepatic bile ducts were not dilated.
Gallbladder morphology and size: No abnormalities were observed; gallbladder wall thickening was not observed; local FDG uptake was not abnormal.
Pancreas morphology: Normal; no obvious abnormal density shadows were observed in the parenchyma; main pancreatic duct was not widened; FDG uptake was not significantly abnormal.
Spleen morphology, size, density, and FDG uptake were not abnormal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly filled, with slight thickening of the walls in part of the gastric body and antrum, and slightly increased FDG uptake (SUVmax = 2.2).
The intestines are poorly filled, with continuous FDG metabolism increased in part of the colon and rectum (SUVmax = 4.5).
FDG metabolism is increased at the anus (SUVmax = 8.3).
The prostate is normal in shape and size, with punctate calcifications seen, but no abnormal FDG metabolism.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies, and L4/5 and L5/S1 intervertebral disc bulging.

Impression

1. a. A mass in the anterior segment of the left upper lobe, with increased FDG metabolism, suggestive of lung cancer, accompanied by surrounding obstructive changes. Please confirm with pathology. b. Multiple lymph node metastases in the left hilum and mediastinum; right hilar lymph node metastasis to be ruled out. c. Solid nodules and plaque-like lesions in both lungs, with normal FDG metabolism, highly suggestive of chronic inflammatory lesions. Annual CT scan recommended. Sequelae of pneumonia in both lungs. Calcification of some arterial walls (including coronary arteries).

2. Slight thickening of the walls in parts of the gastric body and antrum, with mildly increased FDG uptake, suggestive of chronic gastritis; continuous increased FDG metabolism in parts of the colon and rectum, suggestive of inflammatory or physiological uptake. Recommended follow-up gastroscopy and colonoscopy. Hemorrhoidal changes.

3. Benign prostatic hyperplasia with calcification.

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

5. A few ischemic lesions in the deep bilateral cerebral regions; age-related brain abnormalities.

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.
