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, from the top of the skull to the upper thigh: The brain morphology and structure were normal.
A small patch of low-density lesion with relatively clear borders was seen in the right cerebellum.
Multiple punctate and patchy low-density shadows were observed in the brain, with no significant abnormalities in FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical ventricles and no midline shift.
Both eyeballs were symmetrical and without significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, with no abnormalities in FDG uptake.
The pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal fossa and pterygopalatine fossa structures were normal, and the bilateral parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
Pharyngeal tonsils showed physiological uptake bilaterally.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland was normal in shape and size, with slightly uneven density, and no abnormalities in FDG uptake were observed.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Multiple small solid nodules were found in both lungs, with clear borders; the largest was approximately 0.8 cm in long diameter, with slightly increased FDG uptake (SUVmax = 1.5).
Multiple ground-glass opacities were found in both lungs, with clear borders, approximately 0.4?.6 cm in diameter, with normal FDG uptake.
Multiple patchy, calcified, linear, and cystic lucent shadows were observed in both lungs.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
Tracheal diverticulum was present.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
Calcification of the arterial walls was observed, indicating coronary artery stenting.
The cardiac silhouette was slightly enlarged.
No esophageal dilatation was observed, and no significant thickening or mass was observed in the esophageal wall; FDG uptake was not increased.
Bilateral gynecomastia was present.
The liver has an irregular shape and uneven borders.
The hepatic fissure is widened.
A slightly low-density lesion, approximately 2.9cm 2.3cm in size and with indistinct borders, is seen in the right anterior lobe.
FDG uptake is increased (SUVmax = 3.9).
A low-density lesion, approximately 0.9cm in long diameter, with clear borders and absent FDG uptake, is seen in the left lobe.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
The gallbladder has an irregular shape and contains dense nodular lesions, the largest approximately 0.5cm in diameter.
The gallbladder wall is not thickened, and 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, and FDG uptake is normal.
The spleen's shape, size, density, and FDG uptake are normal.
Both kidneys are atrophied.
Multiple low-density lesions, with clear borders and absent FDG uptake, are seen in both kidneys, the largest approximately 5.0cm in long diameter.
Multiple dense lesions are also seen in both kidneys, the largest approximately 1.2cm in length.
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 calcifications observed, but 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 abdominopelvic region or retroperitoneal area.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
Mild anterior displacement of the L3 vertebral body was observed, with some vertebral margin osteophyte formation, and pneumothorax in the L3/4 and L4/5 intervertebral discs.
FDG uptake of the entire bone was normal.

Impression

1. a. Slightly low-density lesion in the right anterior lobe of the liver with increased FDG metabolism, suggestive of malignancy, with hepatocellular carcinoma as the primary consideration. Please combine AFP and enhanced MRI for comprehensive analysis. Multiple solid nodules in both lungs, some with mildly increased FDG metabolism, some metastatic tumors are the primary consideration. Short-term follow-up CT is recommended for comparison. b. Mild cirrhosis, liver cysts.

2. Multiple ground-glass nodules in both lungs, no abnormal FDG uptake, suggestive of atypical adenomatous hyperplasia or chronic inflammatory nodules. Please follow up with CT. Emphysema, chronic inflammation and sequelae in both lungs. Tracheal diverticulum. Calcification of some arterial walls, post-coronary artery stenting. Slightly enlarged cardiac silhouette. Bilateral gynecomastia.

3. Chronic cholecystitis, gallstones. Bilateral renal atrophy, multiple renal cysts and stones. Prostatic calcification.

4. Mild anterior slippage of L3 vertebral body. Spinal osteophyte formation. Pneumodegenerative changes in L3/4 and L4/5 intervertebral discs.

5. Right cerebellar softening lesion, multiple ischemic lesions in the brain, age-related brain changes.

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.
