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 the arms raised, from the top of the skull to the upper thigh.
The brain parenchyma appeared somewhat incomplete, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; midline shift was not observed.
Both eyes were symmetrical, with the right lens showing slightly blurred visualization; no other obvious abnormalities were observed.
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 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; FDG uptake was normal.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The oropharynx and laryngopharynx showed no abnormalities in morphology or structure.
The thyroid gland was normal in shape and size, with slightly uneven density; FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Increased lung markings were present bilaterally, with multiple solid nodules in both lungs, well-defined borders.
The largest nodule, approximately 0.9 cm in diameter, was located in the posterior segment of the right lower lobe, showing increased FDG uptake (SUVmax = 1.3).
Scattered patchy and linear lesions were observed bilaterally, but FDG uptake was not abnormal.
Bilateral pleural thickening was present, but there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette appeared normal.
Post-cardiac surgery, a metallic density shadow was observed in the surgical area, and some arterial walls showed calcification (including the coronary arteries).
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
The liver margins are not smooth, the hepatic fissure is widened, and a large, irregular soft tissue mass is present in the left lobe of the liver.
The mass has indistinct borders, measures approximately 12.0cm 9.8cm 9.9cm, and exhibits heterogeneous density with internal low-density lesions.
FDG uptake is unevenly increased (SUVmax = 7.8), and the mass protrudes beyond the liver outline.
The remaining liver tissue shows heterogeneous density with several slightly low-density lesions, most notably located in the right lobe near the diaphragm, measuring approximately 3.5cm 2.6cm.
FDG uptake is at background levels, and the portal vein is slightly widened.
The hilar and retroperitoneal lymph nodes are visible, the largest being approximately 0.6cm in short diameter, with no abnormal FDG uptake.
The gallbladder is normal in shape and size, with a thickened wall and dense nodules approximately 0.9cm in diameter within, but localized FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density lesions in the parenchyma, and the main pancreatic duct is not widened; FDG uptake is normal.
The spleen is normal in shape, size, density, and FDG uptake.
A few exudative shadows were observed around both kidneys.
A cystic lesion with a long diameter of approximately 3.1 cm was found at the upper pole of the left kidney, with absent FDG uptake.
No widening of the renal pelvis, calyces, or ureter was observed, and FDG uptake was not significantly abnormal.
The left adrenal gland was enlarged, with no abnormal FDG uptake.
No significant abnormalities were observed on the right adrenal gland.
The stomach was poorly distended, with a significant amount of residual contents.
No significant thickening of the gastric wall was observed, and FDG uptake was not significantly abnormal.
The intestines were poorly distended, with no obvious space-occupying lesions.
Continuous FDG uptake was observed in some sections of the intestine (SUVmax = 8.0).
The prostate was enlarged, with a transverse diameter of approximately 6.2 cm, containing patchy dense shadows, and no abnormally increased FDG uptake was observed.
The bladder was poorly distended, with no obvious positive stones.
Decreased bone density was observed throughout the body.
The spinal alignment was normal, with osteophyte formation at the margins of some vertebral bodies and multiple lumbar disc bulges with pneumoconiosis and degeneration.
FDG uptake in all bones was not abnormal.

Impression

1. a. A mass in the left lobe of the liver with increased FDG metabolism, suggestive of hepatocellular carcinoma; several slightly low-density lesions in the remaining liver, with FDG showing background metabolism, metastatic or daughter lesions are the primary consideration, please combine with enhanced MRI for comprehensive analysis. Reactive hyperplasia of the hilar and retroperitoneal lymph nodes. b. Multiple metastatic tumors in both lungs.

2. Chronic inflammation and sequelae in both lungs. Bilateral pleural thickening. Postoperative changes after cardiac surgery, calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis, gallstones. Left adrenal hyperplasia. Left renal cyst. Prostatic hyperplasia with calcification.

4. Chronic inflammatory changes or physiological metabolism in some intestinal segments, please combine with endoscopic follow-up.

5. Osteoporosis, degenerative changes in the spine. Multiple lumbar disc herniations with pneumothorax and degeneration.

6. Age-related brain changes, deep lacunar infarcts.

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.
