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.
A low-density mass, approximately 4.7*2.9cm in size, was observed in the right lateral ventricle trigone and frontoparietal lobe, with relatively clear borders.
FDG uptake was absent, and there was edema in the surrounding brain parenchyma.
The adjacent right ventricle was compressed.
No widening was observed in the ventricles, sulci, fissures, or cisterns.
The ventricles were symmetrical, with a slight leftward deviation of the midline.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was deviated, but the nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal fossa and pterygopalatine fossa structures were normal, and the parapharyngeal spaces were clear bilaterally, with no abnormal FDG uptake.
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 was normal in shape and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
The lung markings were clear.
An irregular soft tissue nodule, approximately 1.6*1.1cm in size, with lobulated, spiculated margins, was observed in the posterior segment of the left upper lobe.
FDG metabolism was increased, with SUVmax=7.8, and some traction was observed on the adjacent pleura.
Multiple solid nodules, approximately 0.2-0.3cm in diameter, were present in both lungs.
FDG uptake was normal.
Increased lung translucency was observed bilaterally, with multiple air-filled cavities.
Scattered calcifications and linear foci were present in both lungs; FDG uptake was normal.
Partial thickening of the left pleura was observed.
There was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were observed in the bilateral pulmonary hila, pretracheal vena cava, right upper trachea, aortic arch, pulmonary artery window, and below the carina.
The largest lymph node had a short diameter of approximately 1.1 cm.
FDG metabolism was increased, with an SUVmax of 6.7.
The cardiac silhouette appeared normal, with cardiac chamber density lower than myocardial density.
Linear dense shadows were observed along the coronary artery course, with some arteriosclerosis.
The esophagus showed no dilation, wall thickening, or mass; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma; FDG uptake was normal.
The main portal vein showed no significant widening; intrahepatic and extrahepatic bile ducts were not dilated.
The gallbladder showed no abnormalities in shape or size, wall thickening, and localized FDG uptake was normal.
The pancreas is normal in morphology, with a cystic lesion in the head region, approximately 1.1 cm in long diameter.
FDG metabolism is normal.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen's morphology, size, density, and FDG uptake are normal.
Both kidneys are irregular in shape, with no widening of the renal pelvis, calyces, or ureters.
FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is poorly filled, with slight thickening of the cardia, part of the gastric body, and antrum walls.
FDG uptake is slightly increased, with SUVmax = 3.3.
The intestines are poorly filled, with a considerable amount of residual contents in the lumen; intestinal uptake is physiological.
The prostate is enlarged, approximately 5.3 cm in long diameter, with no abnormally increased FDG uptake.
The bladder is poorly filled, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and multiple lumbar intervertebral disc bulges.
Small patches of increased FDG uptake were observed bilaterally around the hips, with SUVmax = 3.8.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. Irregular soft tissue nodules with increased FDG metabolism in the apical-posterior segment of the left upper lobe, highly suggestive of lung cancer; please correlate with clinicopathology. Possible metastasis to the right upper tracheal lymph nodes; reactive hyperplasia of the hilar and remaining mediastinal lymph nodes is highly likely, pending further investigation of mixed metastases. b. Chronic inflammatory micronodules in the remaining two lungs; CT follow-up is recommended to rule out other mixed metastases. Emphysema in both lungs. Scattered post-inflammatory lesions in both lungs. Anemia changes, post-coronary stent placement changes, partial arteriosclerosis.

2. Low-density masses in the right lateral ventricle trigone and frontoparietal lobe, with absent FDG uptake, suggestive of malignancy; metastasis is highly probable.

3. Cystic mass in the head of the pancreas, possibly a cyst; MRI with contrast enhancement is recommended for comprehensive analysis. Irregular kidney shape in both kidneys. Benign prostatic hyperplasia.

4. Chronic inflammatory changes or physiological uptake in some intestinal segments; endoscopic follow-up is recommended.

5. Degenerative changes in the spine, multiple bulging lumbar intervertebral discs. Bilateral hip periarthritis.

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.
