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 right cerebellopontine angle showed uneven density, but FDG metabolism was normal.
No abnormal density shadows were seen in the brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no obvious abnormalities.
The right maxillary sinus mucosa was thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, 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 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 enlarged lymph nodes were observed bilaterally in the neck, and FDG metabolism was normal.
A large mass measuring approximately 7.5 6.8 cm was observed in the lower lobe of the left lung, with lobulated and spiculated margins, and increased FDG metabolism (SUVmax = 8.6).
Diffuse solid nodules of varying sizes were observed bilaterally, with a long diameter of approximately 0.3-1.0 cm, and increased FDG metabolism (SUVmax = 5.9).
A few linear shadows were also observed bilaterally, with normal FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Multiple enlarged lymph nodes were observed bilaterally in the supraclavicular fossa, bilateral hila, pretracheal space, para-aortic arch, aortopulmonary window, and below the carina, with the largest having a short diameter of approximately 1.5 cm, and increased FDG metabolism (SUVmax = 4.9).
The cardiac silhouette was normal.
Calcification of some arterial walls was observed (including the coronary arteries).
No esophageal dilation was observed, and no significant thickening or mass was observed in the esophagus; FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious widening, and the intrahepatic and extrahepatic bile ducts were not dilated.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
A nodular dense shadow with a long diameter of approximately 0.6 cm was seen in the upper segment of the left ureter, with mild dilation and hydronephrosis of the proximal ureter and renal pelvis; FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no obvious thickening of the gastric wall and no obvious abnormal FDG uptake.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate was of normal size and uniform density; FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
No significant fluid accumulation was seen 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.
Bone destruction was observed in the L3 and L5 vertebral bodies; FDG metabolism was increased, with SUVmax = 5.9.

Impression

1. a. Large mass in the lower lobe of the left lung, with increased FDG metabolism, suggestive of lung cancer. b. Multiple lymph node metastases in the bilateral hilar, mediastinal, and bilateral supraclavicular fossa. c. Diffuse metastases in both lungs. L3 and L5 vertebral metastases.

2. Uneven density in the right cerebellopontine angle, no abnormalities in FDG metabolism; please repeat with contrast-enhanced MRI.

3. Scattered chronic inflammation and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

4. Stone in the upper segment of the left ureter, mild hydronephrosis and dilation of the proximal ureter and renal pelvis.

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

6. Chronic inflammation of the right maxillary sinus.

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.
