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; 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.
The eyeballs were symmetrical and showed no significant abnormalities.
The maxillary sinus mucosa was slightly thickened bilaterally, but the sinus walls were intact.
The nasopharyngeal wall was not thickened; FDG uptake was normal; the pharyngeal recesses were symmetrical bilaterally; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake was normal.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the parotid and submandibular glands bilaterally.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
An enlarged lymph node, approximately 1.4 cm in diameter, was observed at the left cervical root region, with increased FDG metabolism (SUVmax = 5.6).
Increased translucency was observed in both lungs, with multiple small, round, radiolucent shadows lacking pulmonary markings.
Multiple small nodules, approximately 0.6 cm in diameter, were seen in the right middle lobe and both lower lobes.
A few linear shadows were observed in the right lower lobe.
FDG uptake was normal in all lungs.
No pleural thickening or pleural effusion/pneumothorax was observed bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilum.
The cardiac silhouette was normal.
Calcification was partially observed in the walls of the aorta and coronary arteries.
The esophagus was not dilated, and the walls were not significantly thickened or swollen; FDG uptake was normal.
The liver margins were irregular, with slight widening of the hepatic hilum and fissure.
A large low-density mass, approximately 10.1 8.5 cm in size, with indistinct borders and surrounding low-density nodules, was observed in the right lobe of the liver.
The right portal vein was thickened, with increased FDG uptake (SUVmax = 7.1).
Multiple enlarged lymph nodes were observed at the hepatic hilum, para-aortic region, left para-gastric cardia, bilateral posterior diaphragmatic crura, and right cardiophrenic angle, with a maximum diameter of approximately 1.9 cm.
FDG metabolism was elevated, with an SUVmax of 9.4.
The gallbladder showed no abnormalities in shape or size, with slight wall thickening and no abnormal local FDG uptake.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no significant abnormal FDG uptake.
Bilateral adrenal glands showed no significant abnormalities on contrast.
The stomach was poorly distended, with no obvious thickening of the gastric wall and no significant abnormal FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
A roughly round, low-density lesion measuring approximately 2.2 2.6 cm with relatively clear borders was observed in the middle of the seminal vesicle; FDG metabolism was normal.
The prostate was of normal size and homogeneous density; FDG uptake was not abnormally increased.
The bladder was generally full, and no obvious positive stones were observed.
No significant fluid accumulation was observed in the abdomen or pelvis.
The L3 vertebral body was slightly displaced posteriorly, with osteophyte formation at some vertebral margins; FDG uptake was normal.
Some intervertebral discs showed pneumodesis.
No abnormal FDG metabolism was observed in the entire skeletal system.

Impression

1. a. Liver cirrhosis with a large mass in the right lobe of the liver, elevated FDG metabolism, suggestive of primary liver cancer with intrahepatic dissemination and right portal vein thrombus formation. b. Multiple lymph node metastases in the hepatic hilum, para-aortic region, left para-gastric cardia, bilateral posterior diaphragmatic crura, right cardiophrenic angle, and left cervical root.

2. a. Multiple inflammatory nodules in the right middle lobe and both lower lobes are highly probable; follow-up is recommended to rule out mixed metastases. Bilateral emphysema. A few fibrotic lesions in the right lower lobe. b. Partial calcification of the aortic and coronary artery walls.

3. Chronic cholecystitis. Seminal vesicle cyst.

4. L3 vertebral instability. Spinal osteophyte formation. Partial intervertebral disc degeneration.

5. No obvious abnormalities seen on cranial imaging. Bilateral maxillary sinusitis.

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.
