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.
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.
A solid micronodule, approximately 0.4 cm in diameter, was seen in the left upper lobe; FDG uptake was normal.
A linear opacity was seen in the right lung.
No pleural thickening was seen bilaterally; there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were seen in the bilateral hilar and mediastinal regions.
Several lymph nodes were seen in both axillae, the largest with a short diameter of approximately 0.5 cm; FDG metabolism was slightly increased, SUVmax = 3.5.
The cardiac silhouette was normal.
No esophageal dilation was seen; no significant thickening or mass was seen in the esophageal wall; FDG uptake was normal.
No significantly abnormal density was seen in either breast; FDG metabolism was normal.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
A mixed low-density mass, approximately 3.5*2.9cm in size, with clear borders and calcifications, was observed at the junction of the left and right lobes of the liver.
FDG metabolism was increased, with SUVmax=4.4.
Calcifications were also observed in the right lobe of the liver.
A low-density lesion, approximately 0.5cm in long diameter, with clear borders and absent FDG uptake, was also observed in the right lobe of the liver.
The main portal vein showed no obvious widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder showed no abnormalities in shape and size, with localized thickening of the gallbladder floor wall.
FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal glands show no obvious abnormalities on contrast imaging.
The stomach is poorly distended, with no obvious thickening of the stomach wall, and FDG uptake is not significantly abnormal.
The intestines are poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The uterus is normal in shape, with no abnormal density shadows, and FDG uptake is not abnormally increased.
No abnormal FDG metabolism is seen in the bilateral adnexa.
The bladder wall is not abnormally thickened, and no obvious positive stones are seen within it.
Several small lymph nodes are seen in the hepatogastric space and retroperitoneum, the largest with a short diameter of approximately 0.3 cm; FDG uptake is not abnormal.
No obvious effusion is seen in the abdominal or pelvic cavities.
Spinal alignment is normal, with some vertebral body margin osteophytes, and L3/4, L4/5, and L5/S1 intervertebral disc bulges.
Subcutaneous calcification is present in the left buttock.
Systemic bone FDG metabolism is normal.

Impression

1. a. A mass at the junction of the left and right lobes of the liver with increased FDG metabolism; malignancy is the primary consideration, hemangioma to be ruled out. Further analysis with enhanced MRI is recommended. Reactive hyperplasia of the hepatogastric space and retroperitoneal lymph nodes. b. Calcification in the right lobe of the liver. Cyst in the right lobe of the liver. Adenomyosis of the gallbladder to be ruled out; ultrasound follow-up is recommended.

2. Chronic inflammatory micronodules (solid) in the left upper lobe of the lung. Fibrous lesions in the right lung. Reactive hyperplasia of bilateral axillary lymph nodes.

3. Partial vertebral osteophyte formation. L3/4, L4/5, and L5/S1 intervertebral disc bulges. Subcutaneous calcification in the left buttock.

4. No significant abnormalities were found 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.
