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 revealed: Normal brain morphology and structure, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
Widening of the ventricles, sulci, fissures, and cisterns was observed, but local density and FDG uptake were normal; midline shift was not observed.
Bilateral eyeballs were symmetrical, with no obvious abnormalities.
Thickening of the right ethmoid sinus mucosa was observed, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
Slight thickening of the left nasopharyngeal wall was observed, with increased FDG uptake (SUVmax = 2.6); the left pharyngeal recess was shallower; the Eustachian tube opening was not narrowed; the infratemporal and pterygopalatine fossae were structurally normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
Bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; multiple solid nodules and plaque-like lesions are present in both lungs, the largest being approximately 0.6 cm in diameter; FDG uptake is normal.
Multiple air-filled cavities and scattered linear lesions are present bilaterally; FDG uptake is normal.
No pleural thickening was observed bilaterally; no pleural effusion or pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Cardiac findings are normal.
Calcification of some arterial walls (including coronary arteries) is present.
No esophageal dilatation was observed; FDG uptake in the lower esophageal wall is increased, SUVmax = 2.8.
The liver margins are not smooth.
An irregular soft tissue mass is present in the left lobe of the liver, with indistinct borders and uneven density, measuring approximately 7.5*6.7*6.3cm.
FDG uptake is unevenly increased, with an SUVmax of 10.8.
Several slightly low-density nodules and masses are present in the remaining liver, the largest being located in the right posterior lobe near the top of the diaphragm, measuring approximately 3.9*3.7cm, with increased FDG uptake (SUVmax = 11.2).
Lymph nodes in the hepatogastric space and retroperitoneal region are visible, the largest having a short diameter of approximately 0.9cm; FDG uptake is normal.
The gallbladder is normal in shape and size, with thickened walls; localized 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; FDG uptake is normal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly filled, with slight thickening of the antral wall and mildly increased FDG uptake (SUVmax = 2.0).
Intestinal filling is unsatisfactory, with physiological uptake.
The prostate is full, with calcifications visible, and FDG uptake is not abnormally increased.
The bladder is poorly filled, with no obvious positive stones.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies.
The L5 vertebral body shows bilateral pars interarticularis fracture with slight anterior slippage.
L4/5 intervertebral disc herniation is present.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Multiple space-occupying lesions in the liver with elevated FDG metabolism, suggestive of malignancy, with hepatocellular carcinoma being a strong possibility. Please combine tumor markers for comprehensive analysis. b. Changes associated with cirrhosis. Reactive hyperplasia of lymph nodes in the hepatogastric space and retroperitoneum; follow-up is recommended.

2. Chronic inflammatory nodules in both lungs. Emphysema in both lungs, scattered post-inflammatory lesions in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Chronic cholecystitis. Benign prostatic hyperplasia with calcification.

4. Chronic inflammatory changes in the lower esophagus and gastric antrum; please follow up with endoscopy.

5. Degenerative changes in the spine, bilateral isthmic fracture of the L5 vertebral body with slight anterior slippage of the vertebral body. L4/5 disc herniation.

6. Age-related brain abnormalities, deep lacunar infarcts; please include MRI. Chronic inflammation of the left nasopharyngeal wall and right ethmoid 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.
