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; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The 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 not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 3.8 4.4 cm was observed in the apical segment of the right upper lobe, adjacent to the mediastinum, with lobulated and spiculated margins; FDG metabolism was increased, SUVmax = 8.5.
Multiple solid nodules of varying sizes were observed in the remaining lungs, with a long diameter of approximately 0.3?.4 cm; some showed increased FDG metabolism, SUVmax = 2.6.
Multiple scattered punctate and linear lesions were observed in the remaining lungs; FDG uptake was normal in all cases.
No pleural thickening was observed bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, para-aortic arch, aortic window, subcarinal region, and right supraclavicular fossa.
The largest lymph node had a short diameter of approximately 2.5 cm.
FDG metabolism was increased, with an SUVmax of 6.8.
A small amount of pericardial effusion was present.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, wall thickening, or masses, and FDG uptake was not increased.
The liver had an irregular outline, with diffuse nodules and masses of varying sizes, most of which were fused together.
FDG metabolism was increased, with an SUVmax of 9.9.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened.
Local FDG uptake was normal.
The pancreas had a normal shape, with no obvious abnormal density shadows 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.
A cystic lesion, approximately 3.0 cm in long diameter, was observed in the right kidney, with absent FDG uptake; the left kidney was normal in shape and size, with no obvious abnormal density shadows in the parenchyma, and no widening of the renal pelvis, calyces, or ureter, and no obvious abnormality in FDG uptake.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Stomach distension was poor, with no obvious thickening of the gastric wall, and no obvious abnormality in FDG uptake.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
The prostate was normal in shape and size, with uniform density, and no abnormal FDG metabolism was observed.
Bladder distension was normal, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No obvious effusion was observed 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 bulges.
There is bone destruction in multiple areas of the bilateral scapulae, bilateral multiple ribs, multiple vertebral bodies and appendages of the spine, sacrum, and pelvis.
FDG metabolism is increased, and SUVmax = 6.9.

Impression

1. a. Space-occupying lesion in the apical segment of the right upper lobe, with increased FDG metabolism, suggestive of lung cancer. b. Multiple lymph node metastases in the right hilum, mediastinum, and right supraclavicular fossa. Multiple metastatic tumors in both lungs. Diffuse liver metastases. Multiple bone metastases throughout the body. c. Small amount of pericardial effusion. Calcification of some arterial walls (including coronary arteries). d. Chronic inflammation and old lesions in the remaining lungs.

2. Right renal cyst.

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

4. No abnormalities found on cranial scintigraphy.

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.
