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 images showed: Normal brain morphology and structure; symmetrical areas of decreased density were visible in the anterior horns of both ventricles, with no significant abnormalities in FDG uptake.
Slight widening of the sulci, fissures, and cisterns; symmetrical ventricles with no midline shift.
Symmetrical eyeballs with no significant abnormalities.
No thickening of the paranasal sinus mucosa; sinus walls intact.
No thickening of the nasopharyngeal wall; no abnormalities in FDG uptake; symmetrical pharyngeal recesses; no stenosis of the Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear parapharyngeal spaces with no abnormalities in FDG uptake.
Pharyngeal tonsils showed physiological uptake.
No abnormalities in the morphology and structure of the laryngopharynx.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
Physiological uptake was observed in both thyroid glands.
No significantly enlarged lymph nodes were seen in the bilateral deep cervical spaces, submandibular region, and submental region; FDG metabolism was normal.
Ground-glass nodules were observed in the left upper lobe and the posterior segment of the right lower lobe, the largest measuring approximately 0.6 cm in length.
Multiple solid nodules and calcifications were also seen in both lungs, the largest measuring approximately 0.4 cm in length.
FDG uptake was normal.
Multiple air-transparent shadows without lung markings were observed in both lungs, along with a few streaks.
FDG metabolism was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Calcifications were visible in the walls of the aorta and coronary arteries, but the cardiac silhouette was normal.
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
The liver has irregular edges, widened hepatic fissures, and disproportionate lobes.
Diffuse nodules, masses, or clumps are seen within the liver, some of which are confluent.
The largest cross-section measures approximately 18.2 8.9 cm.
FDG uptake is increased, with an SUVmax of 6.9, suggesting possible involvement of the left and right branches of the portal vein.
A small amount of fluid density shadow is seen around the liver.
Increased peritoneum density is observed in the abdominal and pelvic cavities, but FDG uptake is not significantly abnormal.
Fluid density shadows are also seen in the pelvic cavity.
The gallbladder is small in size with a thickened and rough wall, but FDG uptake is not abnormal.
The pancreas is normal in shape, with no significant abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen's shape, size, density, and FDG uptake are normal.
A small cystic lesion is visible in the right kidney, but FDG metabolism is not abnormal.
The left kidney is normal in shape and size, with no significant abnormal density shadows 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.
The stomach was poorly filled, with slight thickening of the antral wall and increased FDG uptake (SUVmax = 2.9).
The intestines were poorly filled, but no significant thickening or masses were observed in the intestinal wall; FDG uptake was physiological.
The prostate was of normal size and uniform density; no abnormal FDG uptake was observed.
The bladder was generally full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdominal cavity, pelvis, or retroperitoneal region; FDG metabolism was normal.
The spinal alignment was normal, with some vertebral margin osteophytes and L4/5 and L5/S1 intervertebral disc bulging; FDG uptake was normal.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. Liver cirrhosis; multiple intrahepatic lesions with increased FDG uptake, suggestive of malignancy, with a high probability of hepatocellular carcinoma with intrahepatic dissemination; portal vein tumor thrombus formation is also possible. Comprehensive analysis with contrast-enhanced MRI is recommended. b. Abdominal and pelvic effusion; peritoneal seeding metastasis to be ruled out, follow-up is recommended.

2. Slightly thickened gastric antrum wall, increased FDG metabolism, suggestive of inflammation; endoscopic follow-up is recommended to rule out other possibilities.

3. a. One ground-glass nodule each in the left upper lobe and right lower lobe posterior segment, FDG metabolism normal, suggestive of atypical adenomatous hyperplasia or inflammatory nodules; annual HRCT follow-up is recommended. b. Multiple chronic inflammatory nodules and calcifications in both lungs. Emphysema and fibrosis in both lungs. c. Partial calcification of the aorta and coronary artery walls.

4. Chronic cholecystitis. Small renal cyst in the right kidney.

5. Spinal osteophyte formation, L4/5 and L5/S1 intervertebral disc bulge.

6. White matter degeneration. Senile cerebral 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.
