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; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and without 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 and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 4.3 2.9 3.7 cm was observed in the upper lobe of the right lung, with lobulated and spiculated margins, and increased FDG metabolism (SUVmax = 10.1).
Multiple solid nodules of varying sizes were observed in both lungs and the right interlobar pleura, predominantly in the right lung, with a long diameter of approximately 0.3?.0 cm.
Larger nodules showed increased FDG metabolism (SUVmax = 3.9).
A few linear lesions were also observed in both lungs, with normal FDG uptake.
A band-like air-containing lucent shadow was observed in the right pleural cavity.
A small amount of pleural effusion was observed in the right pleural cavity.
Air effusion was observed in the subcutaneous tissue of the right axilla and right chest wall.
Several slightly enlarged lymph nodes were observed in the right hilum, pretracheal space, aortic window, and below the carina.
The largest was located in the right hilum, with a short diameter of approximately 1.0 cm.
FDG metabolism was increased, with SUVmax = 4.2.
The cardiac silhouette was normal.
The esophagus was not dilated, and the wall was not significantly thickened or lumped.
FDG uptake was not increased.
Both breasts were normal, and FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
A slightly low-density nodule was observed in the right lobe, with a long diameter of approximately 0.8 cm.
FDG uptake was normal.
A cystic lesion with a long diameter of approximately 1.0 cm was observed in the left lobe of the liver, with absent FDG uptake.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows seen in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
The left adrenal gland is relatively full and thickened, with a long diameter of approximately 0.8 cm.
FDG metabolism is not abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly distended, with slight thickening of part of the gastric body wall.
FDG metabolism is increased, with SUVmax=3.9.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall.
FDG uptake is physiological.
Postoperative changes to the uterus: A cystic lesion is seen in the cervical region, with a long diameter of approximately 0.8 cm.
FDG uptake is absent.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with minor osteophyte formation at the margins of some vertebral bodies and L4/5 and L5/S1 intervertebral disc bulging.
No abnormalities were observed in systemic bone marrow FDG metabolism.

Impression

1. a. A mass in the upper lobe of the right lung, with increased FDG metabolism, suggestive of lung cancer. Multiple metastatic tumors in both lungs and the right interlobar pleura. b. Metastasis to the right hilar and some mediastinal lymph nodes. Small amount of pleural effusion on the right side. c. A few old lesions in both lungs. Right pneumothorax (15% lung compression). Subcutaneous pneumothorax in the right axilla and right chest wall. d. Left adrenal hyperplasia is highly probable; follow-up CT scan is recommended to rule out metastasis.

2. A slightly low-density nodule in the right lobe of the liver, with normal FDG uptake, suggestive of a cyst or hemangioma; ultrasound follow-up is recommended. Cyst in the left lobe of the liver.

3. Postoperative changes after uterine surgery, cyst in the cervical region.

4. Chronic gastritis.

5. Mild osteophyte formation in the cervical, thoracic, and lumbar spine. L4/5 and L5/S1 intervertebral disc bulge.

6. Cranial scintigraphy showed no abnormalities.

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.
