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: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
The right maxillary sinus mucosa showed slight thickening, while the mucosa of the other paranasal sinuses showed no thickening, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was normal.
The 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 palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Right deep cervical lymph node is slightly enlarged, with a short diameter of approximately 1.4 cm; FDG uptake is increased, SUVmax=4.2.
Lung markings are clear; multiple solid nodules are present in both lungs with well-defined borders; the largest is located in the left posterior basal segment, with a long diameter of approximately 1.2 cm; FDG uptake is increased, SUVmax=4.5.
Patchy shadows are present in the right lower lobe; FDG uptake is normal.
Nodular thickening of the right pleura is accompanied by increased FDG uptake, SUVmax=4.1; no significantly enlarged lymph nodes are seen in the bilateral hilar and mediastinal regions.
Cardiac silhouette is normal; cardiac chamber density is lower than myocardial density.
Bilateral breast tissue is dense; no abnormal density shadows are seen; FDG metabolism is normal.
No esophageal dilation, wall thickening, or mass was observed; FDG uptake was not increased.
Post-hepatocellular carcinoma surgery, patchy FDG uptake was observed around the right abdominal wall incision (SUVmax = 4.5); the right lobe of the liver was partially absent, and the gallbladder was absent; multiple low-density nodules and masses of varying sizes were observed within the liver, the largest being approximately 6.7*5.6cm located beside the right lobe incision margin, with unevenly increased FDG uptake (SUVmax = 11.8); the right branch and main trunk of the portal vein were significantly widened, containing high-density shadows, with a long diameter of approximately 1.5cm, and increased FDG uptake (SUVmax = 4.9); multiple soft tissue nodules were observed on the right side of the abdominal cavity, the largest being approximately 2.6cm in diameter, with increased FDG uptake (SUVmax = 6.0); peritoneal thickening was accompanied by multiple patchy and flocculent shadows, with increased FDG uptake (SUVmax = 6.0); a small amount of effusion was observed in the abdominopelvic cavity.
The hilar and retroperitoneal lymph nodes showed increased FDG uptake (SUVmax = 7.0), with the largest measuring approximately 1.2 cm in short diameter.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with punctate dense shadows in the right renal calyx.
The renal pelvis, calyces, and ureter were not widened, and no obvious abnormalities in FDG uptake were observed.
Bilateral adrenal glands showed no obvious abnormalities.
The stomach was poorly filled, with no obvious thickening of the gastric wall, and no obvious abnormalities in FDG uptake.
The intestines were poorly filled, with a significant amount of residual contents in the intestinal lumen, and some intestinal segments showed increased FDG metabolism (SUVmax = 5.4).
The uterus was normal in shape and size, with no abnormal density shadows, and no abnormalities in FDG uptake.
No obvious abnormalities were found in the bilateral adnexal regions.
Bladder distension was poor, and no obvious positive stones were observed.
Multiple bone lesions with increased FDG uptake were observed in the left adnexa of T4, the T9 vertebral body, the left portion of the sacrum, the right ilium, and the right pubis, with SUVmax = 15.6, the most significant site being the left portion of the sacrum.

Impression

1. a. Postoperative changes in the abdominal wall after liver cancer surgery; multiple space-occupying lesions in the liver with increased FDG metabolism, suggestive of tumor recurrence and metastasis, portal vein tumor thrombus formation. b. Peritoneal seeding metastasis, abdominopelvic effusion; multiple lymph node metastases in the hepatic hilum and retroperitoneum. c. Multiple lung metastases, right pleural metastasis, right pleural effusion. d. Multiple bone metastases throughout the body (see description for details).

2. Chronic inflammation in the lower lobe of the right lung. Anemia.

3. Small kidney stone in the right kidney.

4. Chronic inflammatory changes or physiological uptake in some intestinal segments; please follow up with endoscopy.

5. No obvious abnormalities were found on cranial scintigraphy. Chronic inflammation of the right maxillary sinus. Large inflammatory lymph nodes in the right deep cervical space.

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.
