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 with both hands raised, from the top of the skull to the upper thigh.
The brain morphology and structure were normal, with no abnormal density shadows seen 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.
The left maxillary sinus mucosa was slightly thickened, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
The nasal septum was slightly deviated, but the nasopharyngeal wall was not thickened, 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 abnormalities in FDG uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx were normal in morphology and structure.
The thyroid gland was normal in shape and size, with slightly uneven density, and FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Lung markings were clear bilaterally, with multiple solid nodules of well-defined borders, the largest approximately 0.9 cm in diameter, showing slightly increased FDG uptake (SUVmax = 1.0).
Scattered linear lesions were observed bilaterally, with normal FDG uptake.
Small amounts of pleural effusion were present bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette appeared normal.
Partial arteriosclerosis was observed.
The esophagus showed no dilation, significant wall thickening, or mass, and no increased FDG uptake.
The liver margins were irregular, with disproportionate left and right lobes.
A large, irregular mass was observed in the right lobe and adjacent left medial lobe, with indistinct borders, the largest cross-section measuring approximately 19.0 cm 14.5 cm, exhibiting heterogeneous density with low-density shadows, and heterogeneously increased FDG uptake (SUVmax = 4.3).
The remaining liver shows uneven density.
Focal FDG uptake is observed in the left lobe, with an SUVmax of 3.0.
The largest FDG uptake, approximately 1.3 cm in diameter, is located under the capsule of the left lobe.
FDG uptake is also increased in the left and right branches and main trunk of the portal vein, with an SUVmax of 2.6.
Hilar and retroperitoneal lymph nodes are visible, the largest being approximately 0.9 cm in diameter, with slightly increased FDG uptake (SUVmax of 2.1).
The abdominal and pelvic fat spaces are poorly visualized, and there is significant fluid accumulation in the abdominal and pelvic cavities.
The gallbladder appears normal in shape and size, containing several dense nodules approximately 0.5 cm in diameter.
The gallbladder wall is not thickened, and local FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen is enlarged, but no abnormal density shadows or FDG uptake are observed within the spleen.
Both kidneys are normal in shape and size.
A cystic lesion, approximately 3.5 cm in diameter, is present in the right kidney, with absent FDG uptake.
No widening of the renal pelvis, calyces, or ureter is observed, and FDG uptake is not significantly abnormal.
The left adrenal gland is enlarged with increased FDG uptake (SUVmax = 1.6).
No significant abnormalities are observed on contrast imaging of the right adrenal gland.
Gastric distension is poor, with slight thickening of the cardia, part of the gastric body, and antrum walls, and mildly increased FDG uptake (SUVmax = 1.8).
Intestinal distension is unsatisfactory; several metallic clips are visible in the colon, with continuous increased FDG uptake in some sections (SUVmax = 1.5).
The prostate is full, containing dense nodules approximately 0.5 cm in diameter, with no abnormally increased FDG uptake.
The bladder is poorly distended, with no obvious positive stones.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging.
FDG uptake in all bones is normal.

Impression

1. a. A large, irregular mass in the right lobe of the liver and adjacent left medial lobe with increased FDG metabolism, suggestive of hepatocellular carcinoma; focal FDG metabolism increase in the left lobe of the liver suggests metastasis or daughter lesions; portal vein tumor thrombosis is the primary consideration. Please analyze the above in conjunction with enhanced MRI images. b. Liver cirrhosis, splenomegaly. Reactive hyperplasia of the hilar and retroperitoneal lymph nodes; follow-up is recommended to rule out other possibilities. Abdominal and pelvic effusion. c. Multiple metastatic tumors in both lungs.

2. Scattered fibrotic lesions in both lungs. Small amount of pleural effusion bilaterally. Partial arteriosclerosis.

3. Gallstones. Left adrenal hyperplasia. Right renal cyst. Prostatic hyperplasia with calcification.

4. Postoperative changes after colon polypectomy, some chronic inflammatory changes or physiological metabolic changes in the gastric wall and intestinal tract; please follow up with endoscopy.

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

6. No obvious abnormalities were found on cranial scintigraphy. 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.
