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 scan showed: The brain morphology and structure were normal.
Patchy low-density shadows were seen in the right frontal lobe, and small punctate low-density shadows were seen in the left basal ganglia.
Symmetrical decreased density shadows were seen around the lateral ventricles.
FDG uptake was not significantly abnormal.
The ventricular system was slightly enlarged, with slight widening of the sulci, fissures, and cisterns.
The ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, 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, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal fossa and pterygopalatine fossa structures were normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No significantly enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG metabolism was normal.
Scattered focal air-containing cystic cavities were seen in both lungs, some of which merged to form bullae.
Scattered linear and flocculent density shadows were seen in both lungs, and FDG uptake was normal.
An irregular soft tissue mass with surrounding air-containing cystic cavities was seen in the apical segment of the right upper lobe, with a cross-sectional area of approximately 5.7 3.8 cm.
Vague flocculent density shadows and spiculations were seen around the lesion.
The solid component showed increased FDG metabolism, with SUVmax = 8.7.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
Multiple small lymph nodes were seen in the mediastinum, the largest with a short diameter of approximately 0.5 cm, showing mild FDG uptake, with SUVmax = 3.2.
Partial calcification of the aorta and coronary artery walls.
No esophageal dilation, thickening, or mass was observed in the esophagus; FDG uptake was not increased.
The liver showed no significant abnormalities in shape or size; the liver margins were smooth; the hepatic fissures were not widened; no significant abnormal density shadows were observed in the liver parenchyma on plain CT scan; FDG uptake was normal.
The main portal vein showed no significant widening; no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size; the gallbladder wall was not thickened; local FDG uptake was normal.
The pancreas was normal in shape; no significant abnormal density shadows were observed in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size; no significant abnormal density shadows were observed in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
The right adrenal gland showed no obvious abnormalities on contrast imaging.
The left adrenal gland was full in shape, with increased FDG metabolism (SUVmax = 3.4).
The stomach was poorly distended, with no obvious thickening of the stomach wall and no obvious abnormalities in FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
The prostate was full in shape, with punctate high-density shadows inside, and no abnormally increased FDG uptake.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneal region, and FDG metabolism was normal.
A small amount of fluid-density shadow was seen in the tunica vaginalis of both testes.
Scoliosis was present, with osteophyte formation at the margins of some vertebral bodies, calcification of the nuchal ligament, and L3/4 and L4/5 intervertebral disc bulging, but FDG uptake was normal.
A low-density nodule with sclerosis at the margins is visible anterolaterally to the right femoral head; FDG metabolism is normal.
No abnormal density shadows or abnormal FDG metabolism are observed in either foot.

Impression

1. a. A mass in the apical segment of the right upper lobe, with increased FDG metabolism in the solid component, strongly suggestive of lung cancer; please correlate with clinicopathology. b. Bilateral emphysema with bullae, a few post-inflammatory lesions in both lungs. Reactive hyperplasia of mediastinal lymph nodes. Partial calcification of the aorta and coronary artery walls.

2. Possible left adrenal hyperplasia, adenoma to be ruled out; MRI follow-up recommended. Prostatic calcification. Small amount of hydrocele in both testes.

3. Scoliosis with degenerative changes. L3/4 and L4/5 intervertebral disc bulge. Right femoral head herniation.

4. Small softening lesion in the right frontal lobe, ischemic lesion in the left basal ganglia, white matter degeneration, age-related brain changes; MRI follow-up recommended.

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.
