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.
Multiple ground-glass nodules with indistinct borders, measuring approximately 0.3?.7 cm in length, were observed in both lungs.
Scattered small solid nodules with clear borders, measuring approximately 0.2?.3 cm in length, were also observed in both lungs.
FDG uptake was normal in both lungs.
No pleural thickening or pleural effusion was observed bilaterally.
No significantly enlarged lymph nodes were observed in the hilum or mediastinum bilaterally.
Calcification of some arterial walls (including coronary arteries) was observed.
The cardiac silhouette was normal.
The esophagus was not dilated, and no significant thickening or mass was observed in the esophagus; FDG uptake was not increased.
The liver outline was not smooth, and the hepatic fissure was not widened.
A slightly low-density mass was observed in the right anterior lobe of the liver, with an irregular shape and indistinct borders, measuring 4.7 cm 3.9 cm 6.5 cm; FDG uptake was increased, with an SUVmax of 23.6.
Scattered slightly low-density nodules with indistinct borders were also observed in the right lobe of the liver, the largest measuring approximately 1.2 cm in length; FDG uptake was increased, with an SUVmax of 6.3.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was poorly visualized.
The pancreas was normal in shape, with scattered punctate dense shadows; the main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
The spleen's shape, size, density, and FDG uptake were normal.
Both kidneys were normal in shape and size, with no significant abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG uptake was not significantly abnormal.
Bilateral adrenal glands showed no significant abnormalities on visualization.
Gastric distension was poor, with slight thickening of the walls in parts of the gastric body and antrum, and mildly increased FDG uptake (SUVmax = 3.2).
Intestinal distension was unsatisfactory, with segmental increased FDG uptake in parts of the colon and rectum (SUVmax = 5.6).
The prostate was enlarged, with a transverse diameter of approximately 4.9 cm, and calcifications were observed internally; no abnormal FDG uptake was observed.
The bladder wall was not abnormally thickened, and no obvious positive stones were observed internally.
Several lymph nodes were observed in the hepatogastric space, the largest with a short diameter of approximately 0.8 cm.
FDG uptake was increased, with an SUVmax of 3.6.
A small amount of pelvic effusion was present.
Mild posterior displacement of the L1-3 vertebral bodies was observed, along with calcification of the nuchal ligament.
Osteophyte formation was present at the margins of some vertebral bodies.
Increased density was observed in the L1/2 and L5/S1 vertebral bodies, but FDG uptake was not abnormal.
L4/5 and L5/S1 intervertebral disc bulges were present.
Bone destruction was observed in the T10 vertebral body and the left pubic tubercle, with increased FDG uptake and an SUVmax of 8.7.

Impression

1. a. A slightly low-density mass in the right anterior lobe of the liver with increased FDG metabolism, suggestive of malignancy, with hepatocellular carcinoma being the primary consideration. Please correlate with clinicopathology. Multiple metastases or daughter lesions in the right lobe of the liver. Bone metastases in the T10 vertebral body and left pubic tubercle. b. Reactive hyperplasia of lymph nodes in the hepatogastric space, follow-up required.

2. Multiple ground-glass nodules in both lungs, FDG metabolism normal, suggestive of atypical adenomatous hyperplasia or chronic inflammatory nodules. Please correlate with CT scan. Scattered chronic inflammatory micronodules (solid) in both lungs. Calcification of some arterial walls (including coronary arteries).

3. Chronic gastritis; segmental increased FDG metabolism in some colon and rectum, suggestive of inflammatory changes or physiological metabolism. Follow-up gastroscopy and colonoscopy are recommended for the above.

4. Scattered punctate calcifications in the pancreas. Benign prostatic hyperplasia with calcification. Small amount of pelvic effusion.

5. Mild posterior slippage of the L1-3 vertebral bodies, degenerative changes in the spine. L1/2 and L5/S1 vertebral endplate inflammation. L4/5 and L5/S1 intervertebral disc bulge.

6. A few ischemic foci 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.
