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, and resting, a whole-body PET/CT scan was performed.
The whole-body tomographic images showed:The brain morphology and structure were normal, with a small patchy low-density shadow in the right basal ganglia region; FDG uptake was not significantly abnormal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake was normal; the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was normal.
Enlarged lymph nodes in the left deep cervical space, the largest measuring approximately 1.6 cm in short diameter, with increased FDG uptake (SUVmax = 13.6).
Both lungs show clear lung markings.
Two irregular soft tissue masses with well-defined borders and lobulated edges are seen in the posterior segment of the right upper lobe, measuring 3.4*2.4 cm and 3.2*2.6 cm respectively, with increased FDG uptake (SUVmax = 23.3 and 13.5), and adjacent bronchial truncation.
Several solid nodules with well-defined borders are present in the remaining lungs, the largest approximately 0.3 cm in diameter, with no abnormal FDG uptake.
A few linear lesions are present in the right lung, with no abnormal FDG uptake.
Right pleural thickening is present, but there is no pleural effusion or pneumothorax on either side.
Multiple enlarged lymph nodes were observed in the right hilum, pretracheal space, aortic window, and below the carina.
Some were fused into clusters, the largest measuring approximately 7.2*6.1cm, located in the right anterior superior mediastinal vascular space, encircling the superior vena cava.
FDG uptake was increased, with SUVmax = 22.5.
The cardiac silhouette was normal.
Calcification of some arterial walls (including the coronary arteries) was observed.
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver showed no significant abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
Multiple cystic lesions were observed in the liver, the largest located in the left medial lobe, approximately 2.2cm in diameter, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in localized FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The stomach is poorly filled, with slight thickening of the walls of the cardia, part of the gastric body, and antrum.
FDG uptake is increased, with SUVmax = 6.9.
The intestines are poorly filled, with no obvious space-occupying lesions and exhibiting physiological uptake.
Anal canal FDG uptake is increased, with SUVmax = 7.8.
The prostate is normal in size and density, with no abnormally increased FDG uptake.
The bladder is poorly filled, with no obvious positive stones observed.
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.
Multiple bone destructions with increased FDG uptake were observed in the C1 vertebral body, T1 spinous process, T10 vertebral body, right scapula, right 12th posterior rib, and right acetabulum, with SUVmax = 14.9.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies, and L5/S1 intervertebral disc bulging with pneumoconiosis and degeneration.

Impression

1. a. A mass in the posterior segment of the right upper lobe with elevated FDG metabolism, suggestive of lung cancer; please confirm with pathology. Multiple lymph node metastases in the right hilum, mediastinum, and left deep cervical space. b. Multiple bone metastases throughout the body (see description for details).

2. Small patchy low-density lesions in the right basal ganglia region, with normal FDG metabolism, suggestive of ischemic lesions; further MRI is recommended to rule out metastases.

3. Chronic inflammatory micronodules in both lungs; follow-up with CT is recommended. A few post-inflammatory remnants in the right lung. Right pleural thickening. Calcification of some arterial walls (including coronary arteries).

4. Multiple cysts in the liver.

5. Chronic inflammatory changes or physiological changes in part of the gastric wall, resembling hemorrhoids; please confirm with endoscopy.

6. Degenerative changes in the spine, L5/S1 disc bulge with pneumoconiosis and degeneration.

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.
