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 the arms raised, from the top of the skull to the upper thighs: The brain morphology and structure were normal, with a few punctate low-density shadows in the deep brain regions; FDG uptake showed no significant abnormalities.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
A small amount of mucosal thickening was observed in the right maxillary sinus, but the sinus wall was intact.
The nasopharyngeal wall showed no thickening; FDG uptake showed no abnormalities.
The bilateral 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; FDG uptake showed no abnormalities.
Bilateral palatine tonsil regions showed physiological uptake.
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; FDG uptake showed no abnormalities.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces or submandibular region.
Multiple solid nodules in both lungs, with clear borders, the largest measuring approximately 0.6 cm in length, showing slightly increased FDG uptake (SUVmax = 1.1).
Scattered cystic lucent shadows in both lungs.
A few linear shadows in both lungs, with clear borders.
No pleural thickening or pleural effusion/pneumothorax observed bilaterally.
No significantly enlarged lymph nodes in the hilum or mediastinum bilaterally.
Tracheal diverticulum.
Cardiac enlargement.
No esophageal dilatation, no significant thickening or mass in the esophageal wall, and no increased FDG uptake.
Irregularly shaped liver, with a significantly reduced left lobe and an irregular low-density mass in the right lobe surrounded by multiple small low-density shadows, with indistinct borders, measuring approximately 6.6 cm 5.8 cm, showing increased FDG uptake (SUVmax = 6.3).
Multiple low-density lesions in the liver, with clear borders and absent FDG uptake, the largest measuring approximately 3.8 cm in length.
No significant widening of the main portal vein, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape or size, and the gallbladder wall was not thickened; FDG uptake was normal.
The pancreas showed mild fatty infiltration; the main pancreatic duct was not widened; FDG uptake was not significantly abnormal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size; a low-density lesion with a long diameter of approximately 1.3 cm was seen in the left kidney, with clear borders and absent FDG uptake.
The renal pelvis, calyces, and ureter were not widened; FDG uptake was not significantly abnormal.
An irregular mass measuring approximately 3.4 cm 1.6 cm was present in the left adrenal gland; FDG uptake was increased, with SUVmax = 5.4.
The stomach was poorly distended; the stomach wall was not significantly thickened; FDG uptake was not significantly abnormal.
The intestines were poorly distended; the intestinal wall was not significantly thickened or lumped; FDG uptake was physiological.
The prostate was normal in shape and size, with calcifications present; no abnormal FDG uptake was observed.
The bladder wall showed no abnormal thickening; 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.
The spinal alignment was normal, with calcification of the nuchal ligament.
Osteophyte formation was observed at the margins of some vertebral bodies, with pneumothorax in the L2/3 intervertebral disc and bulging in the L3/4 and L4/5 intervertebral discs.
Following right hip replacement surgery, bone destruction was observed in the proximal segment of the right femur, accompanied by the formation of a soft tissue mass.
The mass was irregular in shape, with indistinct borders, and measured approximately 8.7cm 8.2cm 10.6cm.
FDG uptake was increased, with SUVmax = 8.7.

Impression

1. a. Low-density mass in the right lobe of the liver with increased FDG metabolism, suggestive of hepatocellular carcinoma with intrahepatic metastasis. b. Multiple metastatic tumors in both lungs. Left adrenal metastasis. Right upper femoral metastasis.

2. Mild emphysema in both lungs, a few fibrotic lesions in both lungs. Tracheal diverticulum. Cardiomegaly.

3. Cirrhosis, liver cysts. Left renal cyst. Mild fatty infiltration of the pancreas. Prostatic calcification.

4. Degenerative changes in the spine. L2/3 intervertebral disc pneumothorax. L3/4 and L4/5 intervertebral disc bulges.

5. A few ischemic lesions deep in the brain, age-related brain changes. A few chronic inflammations 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.
