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: Brain morphology and structure were normal, with punctate, slightly low-density shadows in the deep brain regions; FDG metabolism was normal.
The ventricles, sulci, fissures, and cisterns were widened, but local density and FDG uptake were normal; there was no midline shift.
Both eyes were symmetrical with no obvious abnormalities.
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 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 seen in the bilateral parotid and submandibular glands.
The laryngopharynx showed no abnormalities in morphology and structure.
Thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes were seen in the bilateral deep cervical spaces or submandibular region.
Lung markings are clear bilaterally; multiple solid nodules are present in both lungs, the largest being located in the anterior segment of the right upper lobe, approximately 0.8 cm in diameter; FDG uptake is normal.
Multiple patchy, calcified, and linear lesions are present in both lungs; FDG uptake is normal.
Bilateral pleural effusion (partially loculated on the left).
Lymph nodes are visible in the bilateral hilar, pretracheal, para-aortic arch, aortic window, and subcarinal regions; the largest has a short diameter of approximately 0.8 cm; FDG uptake is increased, SUVmax = 3.0.
Cardiac silhouette is normal; pericardial thickening is present; cardiac chamber density is slightly lower than myocardial density.
Calcification of some arterial walls (including coronary arteries) is present.
Bilateral mammary glands are dense, with no abnormal density shadows observed; FDG metabolism is normal.
The esophagus is not dilated, and the wall is not significantly thickened or swollen; FDG uptake is not increased.
The liver is full, with relatively smooth edges; the hepatic fissure is not widened; diffusely distributed slightly low-density nodules and masses are present within the liver, the largest of which is located in the left lobe and adjacent right anterior lobe, with indistinct borders, uneven density, and low-density necrotic areas, measuring approximately 20.3*11.6*10.9cm.
FDG uptake is unevenly increased, with SUVmax=9.5.
No significant dilation of intrahepatic or extrahepatic bile ducts is observed.
Multiple lymph nodes were observed in the porta hepatis, hepatogastric space, retroperitoneum, and right cardiophrenic angle, the largest with a short diameter of approximately 2.0 cm.
FDG uptake was increased, with an SUVmax of 8.2.
Increased density was also observed in the greater omentum and mesentery, with multiple nodules and flocculent shadows.
FDG uptake was slightly increased, with an SUVmax of 2.0.
Abdominal and pelvic effusion was present.
The gallbladder was absent post-cholecystectomy.
The pancreatic head was full with uneven density; the main pancreatic duct was not widened, and FDG uptake was not significantly abnormal.
The spleen's morphology and size were normal, with calcification of the splenic capsule.
FDG uptake was normal.
A soft tissue density nodule approximately 1.0 cm in diameter was observed adjacent to the spleen, with no abnormal FDG uptake.
Both kidneys are normal in shape and size, with several punctate dense shadows in the renal calyces and several cystic lesions in the renal parenchyma, the largest being approximately 2.3 cm in diameter.
FDG uptake is absent.
No widening of the renal pelvis, calyces, or ureters is observed, and FDG uptake is not significantly abnormal.
The left adrenal gland is slightly enlarged with increased FDG uptake (SUVmax = 2.5), while the right adrenal gland shows no significant abnormalities on contrast imaging.
The stomach is poorly distended, with thickening of the gastric wall in the antrum accompanied by increased FDG uptake (SUVmax = 3.7).
There is a considerable amount of residual intestinal contents, with slight thickening of some intestinal walls and increased FDG uptake (SUVmax = 3.2).
The uterus is small, with no abnormal density shadows and no abnormal FDG uptake.
No significant abnormalities are observed in the bilateral adnexa.
The bladder is poorly distended, with no obvious positive stones observed.
Decreased bone density throughout the body, normal spinal alignment, osteophyte formation at the margins of some vertebral bodies, L4/5 and L5/S1 disc herniation with pneumoconiosis and degeneration.
Subcutaneous edema in the abdomen and buttocks.
No abnormalities were observed in FDG metabolism of the entire bone marrow.

Impression

1. a. Multiple space-occupying lesions in the liver with increased FDG metabolism suggest malignancy, possibly metastatic tumors. Please combine tumor markers and enhanced MRI for comprehensive analysis. b. Multiple lymph node metastases in the hepatic hilum, hepatogastric space, retroperitoneum, and right cardiophrenic angle; increased density in the greater omentum and mesentery, multiple nodules and flocculent shadows, slightly increased FDG metabolism, suggesting possible implantation metastasis; abdominopelvic effusion.

2. Thickening of the gastric wall in the antrum with increased FDG metabolism suggests inflammation. Please combine gastroscopy to rule out tumors. Chronic inflammation or physiological uptake of some intestinal segments is possible; please follow up with colonoscopy.

3. a. Chronic inflammatory nodules in both lungs are highly probable; CT follow-up is recommended. Chronic inflammation and post-inflammatory remnants in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Bilateral pleural effusion (partially loculated on the left). b. Pericardial thickening, mild anemia changes, partial arterial wall calcification (including coronary arteries). Bilateral breast hyperplasia.

4. Post-cholecystectomy changes, splenic capsule calcification, accessory spleen. Left adrenal hyperplasia. Bilateral renal calculi, bilateral renal cysts.

5. Osteoporosis, degenerative changes in the spine, L4/5, L5/S1 intervertebral disc herniation with pneumothorax and degeneration. Subcutaneous edema in the abdomen and buttocks.

6. Senile brain, deep lacunar infarcts.

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.
