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.
The whole-body scan showed: A few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no obvious abnormalities.
The maxillary sinus mucosa was thickened bilaterally, but the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with normal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen 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.
Several solid micronodules were observed in the right lung, approximately 0.2-0.3 cm in long diameter, with clear borders; FDG metabolism was normal.
Multiple scattered punctate and linear lesions were also seen in both lungs; FDG metabolism was 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 enlargement was observed.
Calcification of some arterial walls (including coronary arteries) was observed.
An air-filled cavity was seen beside the right trachea.
No esophageal dilation was observed; no significant thickening or mass was seen in the esophageal wall; FDG uptake was normal.
Both breasts were normal; FDG metabolism was normal.
The liver has an irregular outline, an enlarged caudate lobe, and diffuse low-density nodules and masses of varying sizes within the liver, some of which have coalesced into clusters.
FDG metabolism is increased, with SUVmax = 14.5.
The gallbladder is absent post-operatively.
The pancreas is normal in shape, with no obvious abnormal density shadows seen in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen shows no abnormalities in shape, size, density, or FDG uptake.
A cystic lesion is seen in the left kidney, with a long diameter of approximately 3.0 cm, and FDG uptake is absent.
The right kidney is normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
The kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureter are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
Stomach distension is poor, with no obvious thickening of the stomach wall and no obvious abnormalities in FDG uptake.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall; FDG uptake is physiological.
Uterine atrophy, with no abnormal FDG metabolism.
No abnormal FDG metabolism in the bilateral adnexa.
Bladder distension is normal, with no obvious positive stones.
Slightly enlarged lymph node is seen beside the right aorta, with a short diameter of approximately 1.0 cm, increased FDG metabolism, and SUVmax = 2.2.
No obvious effusion is seen in the abdominopelvic cavity.
Kyphosis of the spine, osteophyte formation at the margins of some vertebral bodies, L4/5 and L5/S1 intervertebral disc bulging, and increased density of the L5/S1 articular surfaces.
Decreased bone density in all bones.

Impression

1. a. Diffuse mass in the liver, elevated FDG metabolism, suggestive of malignancy, possibly liver cancer with intrahepatic metastasis; metastatic tumors cannot be ruled out. Please correlate with clinical findings and tumor markers. b. Slightly enlarged lymph nodes beside the right aorta, mildly elevated FDG metabolism, suggestive of reactive lymph node hyperplasia; metastasis to be ruled out.

2. Several small chronic inflammatory nodules in the right lung. Scattered chronic inflammation and old lesions in both lungs. Tracheal diverticulum.

3. Enlarged cardiac silhouette. Calcification of some arterial walls (including coronary arteries).

4. Left renal cyst. Uterus in elderly patients.

5. Degenerative changes in the spine. L5/S1 vertebral endplate inflammation. Osteoporosis. L4/5, L5/S1 intervertebral disc bulge.

6. A few ischemic foci in the deep cerebral regions bilaterally; age-related brain. Chronic inflammation of the bilateral maxillary sinuses.

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.
