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, 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.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical and without significant abnormalities.
Post-operatively, no abnormal FDG metabolism was observed in the surgical area of the right palate tumor.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and no abnormal FDG uptake was observed.
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.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Multiple solid nodules and masses of varying sizes were seen in both lungs, the largest being approximately 3.1 1.7 cm in the lateral basal segment of the right lower lobe, with increased FDG metabolism (SUVmax = 5.9).
A few scattered patchy and linear lesions were also seen in both lungs, with no abnormal FDG uptake in these areas.
No pleural thickening was seen bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
Some arterial walls showed calcification (including the coronary arteries).
The middle and lower esophageal walls were slightly thickened, with increased FDG metabolism (SUVmax = 5.6).
Both breasts were normal, with no abnormal FDG metabolism.
The liver is enlarged with a depressed liver capsule and irregular outline.
Multiple low-density masses and nodules are seen within the liver, the largest being located in the right lobe, measuring approximately 17.2 11.9 cm.
FDG metabolism is increased, with an SUVmax of 11.3.
The adjacent right kidney, right adrenal gland, and pancreas are compressed.
Several cystic low-density lesions are also seen within the liver, the largest being approximately 1.2 cm in long diameter, with absent FDG uptake.
No dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
A cystic lesion measuring approximately 6.0 5.3 cm is seen within the left kidney, with absent FDG uptake.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
No significant abnormalities are observed on contrast imaging of the left adrenal gland.
Stomach distension is poor, with no obvious thickening of the stomach wall, and no significant abnormalities in FDG uptake.
Continuous FDG metabolism in the colon and rectum is increased, SUVmax=5.9.
Uterine atrophy, with no abnormal FDG metabolism.
No abnormal FDG metabolism in the bilateral adnexa.
Bladder distension is normal, 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.
Spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Multiple lesions in the liver with increased FDG metabolism, suggestive of malignancy. The larger lesion in the right lobe of the liver is likely primary. Please combine tumor markers and enhanced MRI for comprehensive analysis. b. Multiple metastatic tumors in both lungs. c. Postoperative right palatal tumor, no signs of tumor recurrence observed in the surgical area.

2. Continuous increased FDG metabolism in the colon and rectum, likely due to inflammatory uptake. Colonoscopy is recommended to rule out tumors.

3. A few chronic inflammations and old lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

4. Inflammatory uptake in the middle and lower esophagus. Liver cyst. Left renal cyst.

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

6. Age-related brain changes.

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.
