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, with no abnormal density shadows in the brain parenchyma, and 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 bilaterally, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
The nasal septum was deviated, the nasopharyngeal wall was not thickened, and the palatine tonsils were symmetrical bilaterally; FDG uptake was physiological.
The laryngopharynx morphology and structure were normal.
The parotid and submandibular glands bilaterally had normal morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
An irregular soft tissue mass in the subpleural segment of the right lower lobe, with indistinct borders and internal cavitation, measures approximately 4.6*3.8*3.8cm, with increased FDG uptake (SUVmax=10.0).
An irregular soft tissue mass in the right hilum, with indistinct borders, measures approximately 6.6*5.0*5.9cm, with increased FDG uptake (SUVmax=11.1).
There is bronchial obstruction in the right lower lobe, with multiple patchy shadows distal to it.
Bilateral pulmonary markings are disordered with interlobular septal thickening, multiple air-filled cavities in both lungs, and scattered patchy and linear lesions in both lungs, with normal FDG uptake.
Bilateral pleural thickening is present.
Lymph nodes are visualized in the right hilum, pretracheal vena cava, aortic window, para-aortic arch, and subcarinal region, the largest measuring approximately 3.0cm in short diameter, with increased FDG uptake (SUVmax=7.3).
Cardiac findings are normal.
Calcification of some arterial walls (including coronary arteries).
No esophageal dilation, thickening or masses in the esophagus, or increased FDG uptake were observed.
The liver showed no significant abnormalities in shape or size, with smooth borders, no widening of the hepatic fissures, and no abnormal density shadows in the liver parenchyma on plain CT scan; FDG uptake was normal.
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 abnormal local FDG uptake.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
The left adrenal gland is enlarged, with no abnormalities in FDG metabolism.
The right adrenal gland shows no obvious abnormalities on contrast imaging.
The stomach is adequately full, with a metallic shadow at the cardia and slight thickening of the gastric wall in the antrum.
FDG uptake is slightly increased, with SUVmax = 2.5.
Intestinal fullness is unsatisfactory, with no local masses and no abnormalities in FDG uptake.
The prostate is of normal size and uniform density, with no abnormally increased FDG uptake.
Bilateral testicular tunica vaginalis calcifications are present.
The bladder is poorly full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
FDG uptake of the entire skeleton is normal.

Impression

1. a. Masses in the right lower lobe and right hilum with increased FDG metabolism, suggestive of lung cancer with obstructive changes; multiple lymph node metastases in the right hilum and mediastinum. b. Bilateral emphysema, bilateral interstitial pneumonia. Bilateral pleural thickening. Calcification of some arterial walls (including coronary arteries).

2. Left adrenal hyperplasia. Bilateral calcifications of the tunica vaginalis.

3. Chronic inflammatory changes in the gastric antrum; please follow up with endoscopy.

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

5. No obvious abnormalities seen 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.
