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: a few punctate low-density shadows in the deep bilateral brain regions, with no significant abnormalities in FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical and showed 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 normal.
The bilateral 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 bilateral palatine tonsils showed physiological uptake.
The laryngopharynx showed no abnormalities in morphology or structure.
The bilateral parotid and submandibular glands showed no abnormal density shadows.
The thyroid gland was normal in shape and size, with slightly uneven density, and increased FDG uptake (SUVmax = 2.1).
A large mass, approximately 4.0 3.5 4.5 cm in size, was observed in the posterior segment of the right upper lobe, closely adhering to the oblique fissure.
FDG metabolism was elevated, with an SUVmax of 9.7.
Stenosis and occlusion of the posterior segment bronchus were also observed.
Several small solid nodules, approximately 0.2-0.3 cm in long diameter, with clear borders, were seen in both lungs; FDG metabolism was normal.
Scattered linear, punctate, and calcified lesions were also observed in both lungs; FDG metabolism was normal.
There was no pleural effusion or pneumothorax bilaterally.
Several lymph nodes were observed in the right hilum, aortic window, and below the carina, the largest approximately 1.2 cm in short diameter, with elevated FDG metabolism and an SUVmax of 4.5.
Some arterial walls showed calcification.
The cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; 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.
A cystic lesion, approximately 0.4 cm in length, was observed in the right posterior lobe of the liver, with no abnormal FDG metabolism.
No other abnormal density shadows or FDG uptake were observed in the remaining liver parenchyma.
The main portal vein showed no obvious widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
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.
An irregular mass, approximately 5.4 5.0 cm in size, was observed at the lower pole of the left kidney, with heterogeneous increased FDG metabolism (SUVmax = 6.2).
Another cystic lesion, approximately 2.7 cm in length, was observed in the left kidney, with absent FDG uptake.
Punctate calcifications were observed in the right renal parenchyma, with no obvious abnormal FDG uptake.
Bilateral adrenal gland enlargement, increased FDG metabolism, SUVmax=3.2.
Stomach poorly distended, antral wall slightly thickened, FDG uptake not significantly abnormal.
Air-filled cavity seen in descending duodenum, FDG metabolism not abnormal.
Intestinal poorly distended, no obvious intestinal mass seen.
Prostate normal size, no abnormal density shadows seen, FDG uptake not significantly increased.
Bladder generally distended, no obvious positive stones seen.
No enlarged lymph nodes seen in abdominal cavity, pelvic cavity, or retroperitoneal region, FDG metabolism not abnormal.
No obvious effusion seen in abdominal or pelvic cavities.
Bone destruction in multiple locations of the sternum, bilateral ribs, spine and appendages, sacrum, and bilateral upper femurs, increased FDG metabolism, SUVmax=8.7.
Spinal alignment normal, some vertebral body margin osteophytes, L4/5 and L5/S1 intervertebral disc bulge.

Impression

1. a. A mass in the posterior segment of the right upper lobe, with elevated FDG metabolism, suggestive of peripheral lung cancer. Multiple bone metastases throughout the body. Possible metastases to the right hilar and mediastinal lymph nodes. b. Several small chronic inflammatory nodules in both lungs are highly probable; follow-up CT scan is recommended to rule out other possibilities. A few chronic inflammations and old lesions in both lungs. Some arterial wall calcifications. c. Bilateral adrenal hyperplasia; follow-up CT scan is recommended to rule out metastasis.

2. An irregular mass in the lower pole of the left kidney, with heterogeneous elevated FDG metabolism, suggestive of malignancy, most likely renal cell carcinoma; please combine clinicopathological examination and contrast-enhanced MRI.

3. Small liver cyst. Left kidney cyst. Right kidney calcification.

4. Duodenal diverticulum. Chronic antral gastritis.

5. Spinal degeneration. L4/5, L5/S1 intervertebral disc bulge.

6. A few deep ischemic lesions in both lobes of the brain, suggestive of age-related brain disorders; follow-up MRI is recommended.

7. If the thyroid gland has uneven density and increased FDG uptake, ultrasound and thyroid function tests are 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.
