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: Uneven density in the right temporal lobe and left frontal lobe, with no abnormalities in FDG metabolism; a few punctate low-density shadows were seen in the deep bilateral brain regions, with no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormalities in 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 is normal in shape and size, with uniform density, and no abnormalities were observed in FDG uptake.
A soft tissue nodule measuring approximately 2.6 2.8 cm with smooth borders was observed near the hilum in the left lower lobe, showing increased FDG metabolism (SUVmax = 15.3).
Partial bronchial stenosis/occlusion was also observed in the left lower lobe.
Extensive thickening of the left pleura (including interlobar pleura) was observed, presenting as flocculent and nodular structures, with increased FDG metabolism (SUVmax = 3.6).
Left-sided pleural effusion was present, some of which was encapsulated.
Thin-walled, air-containing, lucid shadows were observed in the subpleural region of both upper lobes.
Multiple scattered punctate, patchy, and linear shadows were observed in the left lung, some with increased FDG metabolism (SUVmax = 2.9).
Multiple enlarged lymph nodes were observed in the left hilum, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal space, bilateral deep cervical spaces, bilateral supraclavicular fossa, bilateral internal mammary chains, bilateral posterior diaphragmatic crura, and para-aortic region.
The largest lymph node had a short diameter of approximately 1.3 cm, with increased FDG metabolism (SUVmax = 5.6).
Several slightly enlarged lymph nodes were observed in the left axilla, the largest having a short diameter of approximately 0.6 cm.
FDG metabolism was increased (SUVmax = 3.6).
The cardiac silhouette was normal.
Slight pericardial thickening was observed.
Calcification was present in some arterial walls (including the coronary arteries).
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
The liver's morphology and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
Gallbladder: No abnormalities in shape or size, no thickening of the gallbladder wall, and no abnormalities in local FDG uptake.
Pancreas: Normal shape, no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
Spleen: No abnormalities in shape, size, density, or FDG uptake.
Kidneys: Normal shape and size, no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormalities in FDG uptake.
Bilateral adrenal glands: No obvious abnormalities observed on contrast.
Stomach: Poor filling, no obvious thickening of the stomach wall, and no obvious abnormalities in FDG uptake.
Intestinal: Poor filling, no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
Prostate: Normal shape and size, uniform density, and no abnormal FDG metabolism.
Bladder: Moderate filling, and 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.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Increased bone density was observed in the left scapula and L2 vertebral body, with elevated FDG metabolism and an SUVmax of 3.9.

Impression

1. a. A mass near the hilum in the lower lobe of the left lung, with increased FDG metabolism, suggestive of lung cancer. b. Extensive metastasis to the left pleura. Multiple lymph node metastases in the left hilum, mediastinum, bilateral infracervical spaces, bilateral supraclavicular fossa, bilateral internal mammary chains, bilateral posterior diaphragmatic crura, and para-aortic region. Possible reactive hyperplasia of the left axillary lymph nodes, metastasis to be ruled out. c. Emphysema in the upper lobes of both lungs. Scattered inflammation in the left lung. d. Left pleural effusion, partly encapsulated. Slight pericardial thickening. Calcification of some arterial walls (including coronary arteries).

2. Increased local bone density in the left scapula and L2 vertebral body, with increased FDG metabolism, metastasis to be ruled out, close observation recommended.

3. Uneven density in the right temporal lobe and left frontal lobe; no abnormalities observed in FDG metabolism; metastasis needs further investigation. Please combine with contrast-enhanced MRI images from another hospital for comprehensive analysis. A few ischemic lesions in the deep bilateral brain regions.

4. Cervical, thoracic, and lumbar spondylosis. L4/5 and L5/S1 intervertebral disc bulges.

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.
