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 arms raised, from the top of the skull to the upper thigh.
The brain morphology and structure were normal, but white matter density was decreased, with multiple patchy low-density shadows in the deep brain regions and reduced FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical and showed no obvious abnormalities.
There was slight mucosal thickening in the right maxillary sinus, but the sinus wall was 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 bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in morphology and size, with slightly uneven density, and FDG uptake was normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Postoperative suture shadows were seen in the surgical area following right lung cancer surgery.
Multiple ground-glass nodules were observed in both lungs, with indistinct borders; the largest was located in the posterior segment of the left upper lobe, with a long diameter of approximately 2.0 cm.
FDG uptake was normal.
Multiple solid micronodules were observed in both lungs, with well-defined borders, approximately 0.2?.4 cm in diameter.
FDG uptake was normal.
Increased translucency was observed in both lungs, with scattered linear shadows.
FDG uptake was normal.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Calcification of some arterial walls was observed (including coronary arteries).
Increased FDG uptake was observed in a localized area of the left ventricle, measuring approximately 2.0 cm 1.0 cm, with an SUVmax of 8.2.
No esophageal dilatation, significant wall thickening, or mass was observed, and FDG uptake was normal.
The liver is irregular in shape with uneven borders and widened fissures.
A soft tissue mass is seen in the lower segment of the right lobe, with clear borders and uneven density, averaging approximately 42 HU in CT value, measuring approximately 10.7cm 8.0cm, showing increased FDG uptake (SUVmax = 4.1).
Multiple low-density lesions are present in the liver, with clear borders and absent FDG uptake; the largest is approximately 3.5cm in length.
No significant widening of the main portal vein or dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder is normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake.
The pancreas is normal in shape, with no significant abnormal density in the parenchyma, no widening of the main pancreatic duct, and no significant abnormal FDG uptake.
The spleen is normal in shape, size, density, and FDG uptake.
Multiple low-density lesions are present in both kidneys, with one slightly low-density lesion in the left kidney, with clear borders and absent FDG uptake; the largest is approximately 3.7cm in length.
Punctate dense shadows are seen in both renal calyces.
No widening of the renal pelvis, calyces, or ureter was observed, and FDG uptake was not significantly abnormal.
Bilateral adrenal gland imaging showed no significant abnormalities.
Gastric distension was poor, but the gastric wall showed no significant thickening, and FDG uptake was not significantly abnormal.
Intestinal distension was poor, but the intestinal wall showed no significant thickening or mass, and FDG uptake was physiological.
The prostate was normal in size and shape, with uniform density, and no abnormal FDG uptake was observed.
The bladder wall showed no abnormal thickening, and no obvious positive stones were observed.
No enlarged lymph nodes were observed in the abdominoperineal and retroperitoneal regions.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with calcification of the nuchal ligament.
Osteophyte formation was observed at the margins of some vertebral bodies, and pneumothorax was observed in the L4/5 and L5/S1 intervertebral discs.
A uniform dense nodule with clear borders was observed in the right iliac bone, and FDG uptake was not abnormal.
FDG uptake in the entire bone was not abnormal.

Impression

1. Soft tissue mass in the lower right lobe of the liver with increased FDG metabolism, suggestive of hepatocellular carcinoma. Liver cirrhosis. Multiple liver cysts.

2. Postoperative changes after right lung cancer surgery, no obvious signs of tumor recurrence in the surgical area. Multiple ground-glass nodules in both lungs, FDG metabolism normal, suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia. Multiple solid chronic inflammatory micronodules in both lungs. Emphysema, sequelae of pneumonia in both lungs.

3. Calcification of some arterial walls (including coronary arteries). Localized FDG metabolism increase in the left ventricle, physiological metabolism is the primary consideration, pathological changes to be ruled out, echocardiography/enhanced CT follow-up recommended.

4. Multiple cysts in both kidneys, complex cyst in the left kidney. Kidney stones in both kidneys.

5. Spinal degenerative changes. Pneumothorax and degeneration of the L4/5 and L5/S1 intervertebral discs. Bone island in the right iliac bone.

6. Multiple ischemic lesions in the brain, white matter degeneration, age-related brain changes, MRI follow-up recommended. Slight chronic inflammation of the right maxillary sinus.

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.
