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 in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma, and FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical and showed no obvious abnormalities.
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 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, with no abnormal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
The laryngopharynx showed no abnormalities in morphology or structure.
The bilateral parotid and submandibular glands showed no abnormal density shadows.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
Several small lymph nodes, approximately 0.2-0.6 cm in short diameter, were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG metabolism was normal.
Several solid micronodules, approximately 0.2-0.4 cm in long diameter, with clear borders, were observed in both lungs; FDG metabolism was normal.
A few linear and punctate lesions were also observed in both lungs; FDG metabolism was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was full.
Calcification was observed in some arterial walls (including the coronary arteries).
No esophageal dilatation, significant wall thickening, or mass was observed; FDG uptake was not increased.
Both breasts were normal; FDG metabolism was normal.
The liver has an irregular outline with linear dense shadows inside.
An irregular mass measuring approximately 5.9 4.9 cm is seen between the right anterior lobe and left medial lobe, with increased FDG metabolism (SUVmax = 13.7).
The adjacent right lobe bile duct is partially dilated, but FDG uptake is normal.
The main portal vein is not significantly widened.
Several slightly enlarged lymph nodes are seen at the porta hepatis, the largest with a short diameter of approximately 0.6 cm, showing mildly increased FDG metabolism (SUVmax = 6.2).
The gallbladder is normal in shape and size, with slightly thickened walls and nodular dense shadows within the lumen, approximately 1.2 cm in long diameter; FDG metabolism is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and 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 in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is normal.
Bilateral adrenal gland imaging showed no obvious abnormalities.
Gastric distension was poor, with no significant thickening of the gastric wall, and no obvious abnormalities in FDG uptake.
Intestinal distension was poor, with continuous FDG metabolism increased in the sigmoid colon and rectum, SUVmax=5.6.
The uterus was normal in shape, with no abnormal density shadows, and no abnormal FDG metabolism.
No abnormal FDG metabolism was observed in the bilateral adnexa.
The bladder was generally full, with no obvious positive stones.
An inferior vena cava filter was placed, and FDG metabolism was normal.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes, L3-S1 intervertebral disc bulging and pneumothorax, and partial calcification of the anterior longitudinal ligament, nuchal ligament, and supraspinous ligament, but no abnormalities in FDG uptake.
Focal FDG metabolism was observed in the right premandibular region, SUVmax=7.6.

Impression

1. A mass between the right anterior lobe and left medial lobe of the liver, with increased FDG metabolism, suggestive of malignancy, most likely cholangiocarcinoma. Metastasis to the hilar lymph nodes is also highly probable.

2. Schistosomiasis-related liver disease. Chronic cholecystitis. Gallstones. Post-inferior vena cava filter placement changes.

3. Several small, solid, chronic inflammatory nodules in both lungs. A few chronic inflammations and old lesions in both lungs. A full cardiac silhouette with partial calcification of the arterial walls (including the coronary arteries).

4. Continuous increased FDG metabolism in the sigmoid colon and rectum, suggestive of inflammatory or physiological uptake; colonoscopy follow-up is recommended.

5. Degenerative changes in the spine. L3-S1 intervertebral disc bulge and pneumatosis.

6. Inflammatory or physiological uptake in the right premandibular region; clinical correlation is recommended.

7. A few ischemic lesions in the deep bilateral cerebral regions, suggestive of age-related encephalopathy. Reactive hyperplasia of bilateral cervical lymph nodes.

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.
