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; no abnormal density shadows were seen in the brain parenchyma, and FDG uptake was not significantly abnormal.
The ventricles, sulci, fissures, and cisterns were not widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, and no significant abnormalities were observed.
The paranasal sinuses showed no thickening of the mucosa, and the sinus walls were intact.
The nasopharyngeal wall showed no thickening, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the parapharyngeal spaces were clear with no abnormal FDG uptake.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland is normal in shape and size, with low-density nodules in both lobes.
The larger nodule is located in the left lobe, with a long diameter of approximately 1.4 cm.
FDG uptake is normal.
A lymph node is seen in the left deep cervical space, with a short diameter of approximately 0.5 cm.
FDG metabolism is increased, SUVmax = 5.3.
A ground-glass nodule with clear borders is seen in the anterior segment of the left upper lobe, measuring approximately 1.2*0.7 cm.
FDG uptake is normal.
Multiple high-density patchy shadows are seen in the right lower lobe.
Scattered punctate, calcified, and linear shadows are seen in the remaining two lungs.
FDG uptake is normal in all these areas.
Right pleural thickening is present, but there is no pleural effusion or pneumothorax on either side.
No significantly enlarged lymph nodes are seen in the bilateral hilum and mediastinum.
A high-density nodule is seen in the trachea, with a long diameter of approximately 1.0 cm.
FDG uptake is normal.
Calcification of some arterial walls (including coronary arteries) is present.
A small amount of pericardial effusion is present.
The heart is slightly enlarged.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver is irregular in shape, with uneven borders and widened fissures.
CT scan of the right lobe shows a heterogeneous, slightly low-density mass containing slightly high-density shadows with indistinct borders; the CT value is approximately 26 HU, and the long axis is approximately 6.0 cm; FDG metabolism is slightly lower than background levels.
The remaining liver parenchyma has decreased density, with a CT value of approximately 45 HU; FDG uptake is normal.
Ascites is present.
Multiple tortuous and widened blood vessels are visible in the abdominal cavity.
The gallbladder is blurred, with thickened walls and multiple dense nodules measuring approximately 2.8*1.5 cm; FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density in the parenchyma; the main pancreatic duct is not widened; FDG uptake is normal.
Spleen enlarged, density and FDG uptake normal.
Both kidneys normal in shape and size, multiple low-density lesions in both kidneys, the largest located in the right kidney, approximately 3.3 cm in diameter, with clear borders, and absent FDG uptake.
No widening of the renal pelvis, calyces, or ureters, and no significant abnormality in FDG uptake.
No significant abnormality in bilateral adrenal gland imaging.
Poor gastric distension, no significant thickening of the gastric wall, and no significant abnormality in FDG uptake.
Poor intestinal distension, no significant thickening or mass in the intestinal wall, and FDG uptake is physiological.
Prostate normal in shape and size, with calcifications, and no abnormal FDG metabolism.
No abnormal thickening of the bladder wall, and no obvious positive stones.
Bilateral hydrocele.
No enlarged lymph nodes in the abdominopelvic region or retroperitoneal area.
Pelvic effusion.
Nuchal ligament calcification.
Spinal alignment normal, with marginal osteophyte formation at some vertebral bodies, L4/5 and L5/S1 disc bulging and pneumothorax.
Increased subcutaneous fat density in the abdomen and lower extremities, with no abnormal FDG uptake.
Systemic bone FDG metabolism normal.

Impression

1. a. Right lobe of liver lesion, FDG uptake slightly reduced compared to background levels, liver cancer suspected based on medical history. Cirrhosis, splenomegaly, fatty liver. b. Portal hypertension with open collateral circulation, ascites/pelvic effusion.

2. a. High-density nodular shadow in the trachea, FDG uptake normal, sputum plug possible, neoplastic lesion to be ruled out, follow-up recommended. b. Ground-glass nodule in the anterior segment of the left upper lobe, FDG uptake normal, chronic inflammatory nodule suspected, follow-up with CT scan recommended. c. Chronic inflammation in the right lower lobe. Scattered post-inflammatory lesions in the remaining lungs. Right pleural thickening. d. Small amount of pericardial effusion. Slightly enlarged cardiac silhouette. Calcification of some arterial walls (including coronary arteries).

3. Low-density thyroid nodule, FDG uptake normal, suggestive of nodular goiter, please repeat ultrasound examination. Reactive hyperplasia of left deep cervical lymph nodes.

4. Cholecystitis, gallstones. Bilateral renal cysts. Prostatic calcification. Bilateral hydrocele.

5. Spinal degenerative changes. L4/5, L5/S1 intervertebral disc bulge, pneumothorax. Subcutaneous edema of abdomen and lower extremities.

6. No obvious abnormalities seen on cranial FDG 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.
