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.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were 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 and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
Both palatine tonsils showed physiological uptake.
A small nodule in the deep lobe of the left parotid gland, approximately 1.0 cm in diameter, showed increased FDG uptake (SUVmax = 2.9).
No abnormal density shadows were observed in the right parotid and submandibular glands.
The morphology and structure of the laryngopharynx are normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
The lung markings are clear bilaterally; multiple solid nodules are present in both lungs, the largest approximately 0.3 cm in diameter; FDG uptake is normal.
Multiple air-filled cavities and a few linear lesions are present in both lungs; FDG uptake is normal.
The pleura is slightly thickened bilaterally; there is no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
The cardiac silhouette is normal.
The cardiac chamber density is lower than that of the myocardium; some arteriosclerosis is present.
The esophagus is not dilated; the esophageal wall is not significantly thickened or swollen; FDG uptake is normal.
Following liver cancer treatment, the liver margins were not smooth, the left and right lobes were disproportionate, the hepatic fissures were widened, and multiple nodules and patchy low-density lesions were observed in the liver, some of which were fused together with indistinct borders, most prominent in the right lobe.
The largest cross-section measured approximately 10.8*7.9cm, with uneven density and increased uneven FDG uptake (SUVmax=4.6).
Small cystic lesions were found within the liver, approximately 0.5cm in diameter, with no abnormalities in FDG metabolism.
Increased FDG uptake in the portal vein was observed (SUVmax=3.7), and the portal vein was widened, with a long diameter of approximately 2.0cm.
Multiple varices were observed in the lower esophagus and retroperitoneum.
Lymph nodes in the hepatogastric space and retroperitoneum were visualized, the largest with a short diameter of approximately 0.8cm, showing slightly increased FDG uptake (SUVmax=1.9).
A left supradiaphragmatic lymph node, approximately 1.5*0.6cm in size, was visualized, showing increased FDG uptake (SUVmax=2.7).
Significant ascites was present in the abdominal and pelvic cavities, and the fat spaces within the abdominal and pelvic cavities were poorly visualized.
Gallbladder: No abnormalities in shape or size; no thickening of the gallbladder wall; increased density within the gallbladder; no abnormal local FDG uptake.
Pancreas: Normal shape; no obvious abnormal density shadows seen in the parenchyma; no widening of the main pancreatic duct; no obvious abnormal FDG uptake.
Splenomegaly; nodular and patchy low-density lesions seen within the spleen; absent FDG uptake.
Kidneys: Normal shape and size; no obvious abnormal density shadows seen in the parenchyma; no widening of the renal pelvis, calyces, or ureters; no obvious abnormal FDG uptake.
Bilateral adrenal glands: No obvious abnormalities seen on contrast.
Stomach: Poor distension; partial thickening of the gastric wall; increased FDG uptake; SUVmax = 3.6.
Intestinal distension: Insufficient; physiological uptake observed.
Prostate: Normal size; punctate dense shadows seen within; no abnormally increased FDG uptake.
The bladder was not fully filled, but no obvious stones were observed.
The spinal alignment was normal, with mild osteophyte formation at the margins of some vertebrae.
Overall bone density was normal, and calcification of the nuchal ligament was present.
Systemic bone marrow FDG metabolism was normal.

Impression

1. a. After liver cancer treatment, multiple space-occupying lesions in the liver with increased FDG metabolism suggest the tumor may still be active. Portal vein tumor thrombus formation is also possible; please confirm with an MRI. Slightly increased FDG metabolism is observed in the hepatogastric space, retroperitoneum, and left supradiaphragmatic lymph nodes, suggesting reactive hyperplasia. Metastasis is not ruled out; follow-up is recommended. b. Liver cirrhosis, splenomegaly, portal hypertension with collateral circulation formation. Large amount of effusion in the abdominopelvic cavity.

2. Chronic inflammatory micronodules in both lungs. Emphysema in both lungs, a few post-inflammatory remnants in both lungs. Slight thickening of the pleura bilaterally. Anemic changes, partial arteriosclerosis.

3. Small hepatic cysts. Concentrated bile or sludge-like stones in the gallbladder. Splenic infarction. Prostatic calcification.

4. Partial chronic inflammatory changes in the gastric wall; please confirm with endoscopic follow-up.

5. Mild vertebral osteophyte formation. Nuchal ligament calcification.

6. Small nodule in the left parotid gland with increased FDG metabolism, suggestive of lymphoma; please combine with contrast-enhanced MRI for comprehensive analysis.

7. No obvious abnormalities were found on cranial scintigraphy.

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.
