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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging was performed with arms raised, from the top of the skull to the upper thighs: Brain morphology and structure were normal, with a few punctate low-density shadows in the deep brain regions; FDG uptake showed no significant abnormalities.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical bilaterally, 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.
The nasopharyngeal wall was not thickened; FDG uptake showed no abnormalities.
The pharyngeal recesses were symmetrical bilaterally, and the Eustachian tube openings were not narrowed.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear; FDG uptake showed no abnormalities.
Bilateral palatine tonsil regions 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 was normal in shape and size, with slightly uneven density; FDG uptake showed no abnormalities.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
A small solid nodule with clear borders, approximately 0.8 cm in diameter, was observed in the right middle lobe of the lung.
FDG uptake was slightly elevated, with an SUVmax of 1.6.
Multiple small solid nodules with clear borders, approximately 0.2?.5 cm in diameter, were observed in the remaining lungs.
FDG uptake was normal.
A few linear opacities were observed in the right lower lobe.
A cystic lucent opacity was observed in the left lower lobe.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Calcification of some arterial walls (including the coronary arteries) was observed.
The cardiac silhouette was normal.
No esophageal dilation, significant wall thickening, or mass was observed, and FDG uptake was normal.
The liver was enlarged.
A large, slightly hypodense mass, approximately 14.0 cm 12.0 cm in size, was observed in the right lobe of the liver.
FDG uptake was elevated, with an SUVmax of 10.7.
Multiple slightly low-density nodules and masses were observed in the liver, the largest measuring approximately 2.8 cm in long diameter, with increased FDG uptake (SUVmax = 7.8).
Slightly enlarged lymph nodes were seen near the porta hepatis and in the hilar space, the largest measuring approximately 0.8 cm in short diameter, with slightly increased FDG uptake (SUVmax = 2.9).
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened; FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, and the main pancreatic duct was not widened; FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size; a low-density lesion with a long diameter of approximately 1.0 cm was seen in the left kidney, with clear borders and slight calcification at the edges; FDG uptake was absent.
The renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The stomach was poorly distended; the gastric wall was not significantly thickened; FDG uptake was normal.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate was enlarged, approximately 4.5 cm in diameter, with calcifications visible.
Mildly increased FDG uptake was observed in the right peripheral zone (SUVmax = 3.2).
The bladder wall showed no abnormal thickening, and no obvious positive stones were seen.
No significant fluid accumulation was observed in the abdomen or pelvis.
Multiple bone destructions were observed in the left scapula, left 6th rib, T8, T10, T11 vertebrae, and sacrum; soft tissue shadows were present in the left scapula; FDG uptake was increased (SUVmax = 10.3).
The spinal alignment was normal, with calcification of the nuchal ligament.
Osteophyte formation was observed at the margins of some vertebral bodies.

Impression

1. a. A large, slightly low-density mass in the right lobe of the liver with increased FDG metabolism; multiple slightly low-density nodules and masses within the liver with increased FDG metabolism, suggestive of hepatocellular carcinoma with multiple intrahepatic lesions. Metastasis to the perihepatic and hilar lymph nodes is possible. b. Metastatic tumor in the right middle lobe of the lung. Multiple solid micronodules in the remaining two lungs, with normal FDG metabolism; chronic inflammatory nodules are the primary consideration, but some metastases cannot be ruled out. Please review with a CT scan for comparison. c. Multiple bone metastases.

2. A few remnants of chronic inflammation in the right lower lobe. A bulla in the left lower lobe. Calcification of some arterial walls (including coronary arteries).

3. Possible left renal cyst; please review with an MRI.

4. Benign prostatic hyperplasia with calcification; mildly increased FDG metabolism in the right peripheral zone; inflammatory lesions are the primary consideration; please review with a PSA test to rule out other possibilities.

5. Spinal degenerative changes.

6. A few ischemic lesions deep in the brain, 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.
