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 with both hands raised, extending from the top of the skull to the upper thigh.
The scan showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities were observed in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa; the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; no abnormalities were observed in FDG uptake; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally; and no abnormalities were observed in FDG uptake.
No abnormalities were observed in FDG uptake in the oropharynx and laryngopharynx.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density; and no abnormalities were observed in FDG uptake.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
Multiple solid nodules were observed in both lungs, with relatively clear borders; the largest nodule had a long diameter of approximately 0.3 cm; FDG uptake was normal.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac chamber density was slightly lower than that of the myocardium.
The liver margins were irregular, the hepatic fissure was widened, and the liver lobe proportions were disproportionate.
A large, slightly hypodense mass was observed within the liver, with indistinct borders, mostly located in the right lobe; FDG uptake was increased, measuring approximately 16.4 cm 16.2 cm, with an SUVmax of 9.1; both branches and the main trunk of the portal vein were involved.
The peritoneum in the abdominopelvic region showed increased density and mild FDG uptake; SUVmax was 1.4.
A small amount of fluid-density shadow was observed around the liver and spleen and within the pelvic cavity.
Multiple lymph nodes were observed in the hepatogastric space and retroperitoneum, the largest with a short diameter of approximately 0.6 cm, showing increased FDG uptake (SUVmax = 2.6).
The gallbladder wall was thickened and roughened, with increased density within the lumen; a short, high-density shadow with a long diameter of approximately 1.4 cm was visible, but FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma; the main pancreatic duct was not widened, and FDG uptake was normal.
The spleen was enlarged, with its lower pole extending beyond the lower border of the liver; FDG uptake was normal.
Small splenic nodules were observed around the spleen, but FDG uptake was normal.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma; the renal pelvis, calyces, and ureters were not widened, and FDG uptake was normal.
Bilateral adrenal glands showed no obvious abnormalities on contrast.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen; FDG uptake was normal.
The stomach was poorly filled, with slight thickening of the antral wall and increased FDG uptake (SUVmax = 3.3).
The intestines were poorly filled, but no obvious thickening or masses were observed in the intestinal wall; FDG uptake was physiological.
The prostate was of normal size and uniform density; FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
The spine showed slight scoliosis and osteophyte formation at the margins of some vertebrae; FDG uptake was not abnormal.
No abnormal FDG uptake was observed in any of the bones.

Impression

1. a. A large, slightly low-density mass in the liver with increased FDG metabolism, suggestive of hepatocellular carcinoma with invasion of the left and right branches and main trunk of the portal vein; multiple lymph node metastases in the hepatogastric space and retroperitoneum. b. Increased peritoneal density in the abdominopelvic region with mild FDG metabolism, metastasis to be ruled out; abdominopelvic effusion. c. Liver cirrhosis with splenomegaly.

2. Multiple chronic inflammatory micronodules in both lungs. Slight pleural thickening bilaterally. Mild anemia.

3. Chronic gastritis, endoscopic follow-up recommended.

4. Gallstones and chronic cholecystitis. Accessory spleen.

5. Slight scoliosis with osteophyte formation.

6. No obvious abnormalities seen on cranial imaging.

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.
