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 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, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
The left maxillary sinus mucosa was thickened, but the sinus wall was intact.
The nasopharyngeal wall was not thickened, and FDG uptake showed no abnormalities.
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; FDG uptake showed no abnormalities.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen 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 seen in the bilateral deep cervical spaces or submandibular region.
Multiple punctate, patchy, and linear opacities were observed in both lungs, with normal FDG uptake in all cases.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Multiple small mediastinal lymph nodes were present, the largest with a short diameter of approximately 0.5 cm; some showed slightly increased FDG uptake (SUVmax = 4.0).
Calcification of some arterial walls was observed (including the coronary arteries).
The cardiac silhouette appeared normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
No significant abnormal density was observed in either breast, and FDG uptake was normal.
The liver had an irregular shape, irregular borders, and widened hepatic fissures.
A slightly low-density mass, approximately 5.3 cm 4.9 cm in size, with clear borders, was observed in the left medial lobe of the liver, showing increased FDG uptake (SUVmax = 4.4).
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
This patient had undergone cholecystectomy.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
Accessory splenic nodules are visible.
Both kidneys are normal in shape and size; a punctate dense shadow is seen in the left renal calyx; the renal pelvis, calyces, and ureter are not widened, and FDG uptake is not obvious.
Bilateral adrenal glands show no obvious abnormalities on contrast imaging.
The stomach is poorly distended, with no obvious thickening of the gastric wall, and no obvious abnormalities in FDG uptake.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The uterus is normal in shape, with no abnormal density shadows, and no abnormally increased FDG uptake.
No abnormal FDG uptake is seen in the bilateral adnexa.
The bladder wall is not abnormally thickened, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdominopelvic region or retroperitoneal region.
No obvious effusion is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes, and L4/5 and L5/S1 intervertebral disc bulges.
Increased FDG uptake around both shoulder joints, SUVmax = 3.6.
Right iliac bone island.

Impression

1. a. A slightly low-density mass in the left inner lobe of the liver with increased FDG metabolism, strongly suggestive of hepatocellular carcinoma; please confirm with pathology. b. Liver cirrhosis. Accessory spleen. Post-cholecystectomy.

2. Multiple chronic inflammatory lesions and sequelae in both lungs. Reactive hyperplasia of mediastinal lymph nodes. Calcification of some arterial walls (including coronary arteries).

3. Left renal calculi.

4. Spinal osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge. Bilateral frozen shoulder. Right iliac bone island.

5. A few ischemic lesions deep in the brain. Senile cerebral changes. Left maxillary sinusitis.

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.
