Whole-body 18F-FDG PET/CT scan in a patient with Liver 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, and resting, a whole-body PET/CT scan was performed.
The whole-body scan showed: The brain morphology and structure were normal.
A slightly high-density nodule, approximately 2.1 cm in length, was seen under the right parietal cranial plate, with increased FDG uptake (SUVmax = 7.9).
Another slightly high-density nodule with punctate calcifications was seen in the right occipital lobe, approximately 1.7 cm in length, with increased FDG uptake (SUVmax = 6.6).
No widening of the ventricles, sulci, fissures, or cisterns was observed.
The ventricles were symmetrical, and there was no midline shift.
Both eyes were symmetrical, with no obvious abnormalities.
Thickening of the left maxillary sinus mucosa was observed, but the sinus wall was 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 fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was normal.
A solid nodule, approximately 0.3 cm in long diameter, with clear borders, was seen in the posterior segment of the right upper lobe and beside the oblique fissure of the left lower lobe; FDG metabolism was normal.
Punctate calcifications were seen in the right upper lobe; a few punctate and linear lesions were also seen in both lungs; FDG metabolism was normal.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
Multiple enlarged lymph nodes were seen in the right infracervical space, left hilum, and below the tracheal carina; the largest had a short diameter of approximately 1.5 cm; FDG metabolism was increased, with SUVmax = 11.3.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
No esophageal dilation was observed, and no significant thickening or mass was seen in the esophageal wall.
FDG uptake was not increased.
The liver outline was irregular.
A low-density mass measuring approximately 7.9 8.2 cm was seen in the right anterior lobe of the liver, with increased FDG metabolism (SUVmax = 8.8).
Mild dilation of the intrahepatic bile ducts was observed.
Multiple enlarged lymph nodes were seen in the porta hepatis, hepatogastric space, around the pancreatic head, and in the portal vena cava space, the largest with a short diameter of approximately 2.5 cm.
FDG metabolism was increased (SUVmax = 10.4).
An irregular mass measuring approximately 5.7 4.5 cm was seen in the left adrenal gland, with increased FDG metabolism (SUVmax = 8.7).
The gallbladder was normal 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.
The main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
Spleen morphology, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size.
Two cystic low-density lesions were seen at the edge of the left kidney, the larger one approximately 1.1 cm in long diameter.
FDG uptake was normal.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Stomach distension was poor, but the stomach wall was not significantly thickened.
FDG uptake was not significantly abnormal.
FDG metabolism was increased in some intestinal segments, SUVmax = 4.5.
The prostate was full in shape, approximately 5.0 cm in transverse diameter, with punctate calcifications inside.
No abnormal FDG metabolism was observed.
Bladder distension was normal, and no obvious positive stones were seen inside.
No significant fluid accumulation was seen in the abdomen or pelvis.
The spinal alignment is normal, with some vertebral body margin osteophytes, and calcification of parts of the anterior longitudinal ligament, nuchal ligament, and supraspinous ligament.
L4/5 and L5/S1 intervertebral disc bulges are present.
Systemic bone marrow FDG metabolism is normal.

Impression

1. A mass in the right anterior lobe of the liver, a mass in the left adrenal gland, and multiple enlarged lymph nodes in the abdominal cavity, retroperitoneum, left hilum, mediastinum, and right infracervical space, all with increased FDG metabolism. Malignancy is suspected, possibly a primary liver tumor with multiple metastases; lymphoma cannot be ruled out. A biopsy is recommended.

2. A slightly high-density nodule with increased FDG metabolism is seen under the right parietal cranial plate, suggesting a possible meningioma; a slightly high-density nodule with increased FDG uptake is seen in the right occipital lobe, suggesting a possible benign lesion. Further enhanced MRI is recommended.

3. Chronic inflammatory nodules in the posterior segment of the right upper lobe and beside the oblique fissure of the left lower lobe. Calcification in the right upper lobe. A few chronic inflammations and old lesions in both lungs. Calcification of some arterial walls.

4. Increased FDG metabolism in some intestinal segments, suggesting inflammatory or physiological uptake.

5. Left renal cyst. Benign prostatic hyperplasia with calcification.

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

7. Chronic inflammation of the left 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.
