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's long diameter was approximately 0.3 cm.
Scattered linear shadows were also observed in both lungs; FDG uptake was normal.
The bilateral pleura was slightly thickened, but there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
A few glandular density shadows were observed in the bilateral breast areas; FDG uptake was normal.
The liver margins were not smooth, and the liver lobes were disproportionate; the left lobe was slightly smaller, and a round mass with indistinct borders, heterogeneous internal density with necrosis and liquefaction was observed in the right lobe; FDG uptake was increased, with a size of approximately 11.7 cm 10.3 cm and an SUVmax of 10.6.
Multiple lymph nodes were observed in the pancreatic head region and the mesenteric region of the mid-abdomen; the largest nodule's short diameter was approximately 0.4 cm; some showed increased FDG uptake, with an SUVmax of 1.3.
The right branch of the portal vein is not clearly visible.
The gallbladder is of acceptable shape, with several small, round or irregular high-density shadows within the lumen, the largest being approximately 2.0cm 1.0cm.
A mound-like protrusion, approximately 0.9cm 0.7cm, is also seen at the base.
FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is normal.
The spleen is normal in shape, size, density, and FDG uptake.
Both kidneys are normal in shape and size, with a small, round, high-density shadow in each renal calyx, the larger one approximately 0.2cm in long diameter.
FDG uptake is normal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen.
FDG uptake is not increased.
The stomach is poorly distended, with no significant thickening of the gastric wall.
FDG uptake is normal.
The intestines are poorly distended, with no significant thickening or swollen intestinal wall.
FDG uptake is physiological.
The prostate is of acceptable morphology, with punctate calcifications visible internally; FDG uptake is not abnormally increased.
The bladder is generally full, with no obvious positive stones.
A linear density shadow is seen on the right side of the pelvis, with slightly increased density (CT value approximately 38 HU), and partially increased FDG uptake (SUVmax = 1.3).
The spinal alignment is normal, with some vertebral body margin osteophytes and L3/4 and L4/5 intervertebral disc bulging; FDG uptake is not abnormal.
No abnormal FDG uptake is observed in any of the bones.

Impression

1. a. A large mass with necrosis in the right lobe of the liver, with increased FDG metabolism, suggestive of hepatocellular carcinoma; please correlate with clinicopathology. b. A linear shadow in the right pelvic region, with some mild FDG metabolism, suggesting possible hematoma; implantation metastasis to be ruled out. c. Multiple reactive hyperplasia of lymph nodes in the pancreatic head region and mid-abdomen mesenteric region; follow-up is recommended. d. The right branch of the portal vein is not clearly visualized.

2. Multiple chronic inflammatory micronodules in both lungs, with a few post-inflammatory remnants in both lungs. Slight thickening of the pleura bilaterally. Bilateral gynecomastia.

3. Multiple gallstones and adenomyomatosis of the gallbladder. Small kidney stones bilaterally. Calcifications in the prostate.

4. Spinal osteophyte formation. L3/4 and L4/5 intervertebral disc bulge.

5. No obvious abnormalities were 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.
