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, with no abnormal density shadows seen in the brain parenchyma, and no significant abnormalities in FDG uptake.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The bilateral eyeballs had normal morphology and outlines, clear retrobulbar structures, and symmetrical optic nerves, with no abnormal FDG uptake.
Slight thickening of the mucosa in the right sphenoid sinus and bilateral ethmoid sinuses was observed, but the sinus walls were intact, and FDG uptake was absent.
No thickening was observed in the nasopharyngeal wall; there was no stenosis in the bilateral pharyngeal recesses or Eustachian tube openings; the infratemporal fossa and pterygopalatine fossa structures were normal; the bilateral parapharyngeal spaces were clear, and FDG uptake was normal.
FDG uptake in the oropharynx and laryngopharynx was physiological.
No abnormal contrast was observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with slightly uneven density, and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
Several small, solid nodules were observed in the apical-posterior segment of the left upper lobe, the right interlobar fissure, and the lateral basal segment of the right lower lobe.
These nodules were regular in shape, with clear borders, and a long diameter of approximately 0.3?.5 cm.
FDG uptake was normal.
A few linear and flocculent density shadows were also observed in both lungs, with no abnormal FDG uptake.
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.
The cardiac silhouette was normal.
The liver was slightly irregular in shape.
On plain CT scan, a slightly low-density nodule measuring approximately 2.9 cm 2.0 cm was observed in the lower segment of the right lobe of the liver.
The nodule had indistinct borders, increased FDG uptake (SUVmax = 16.3), and several small low-density nodules with smooth margins were observed within the liver parenchyma.
The largest nodule had a long diameter of approximately 0.7 cm and no FDG uptake.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder was absent post-cholecystectomy.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
A splenic nodule with a long diameter of approximately 2.5 cm was seen adjacent to the spleen, with no abnormalities in FDG uptake.
Both kidneys were normal in shape and size, with small low-density lesions in the renal parenchyma.
The renal pelvis, calyces, and ureters were not widened, and no obvious abnormalities in FDG uptake were observed.
The left adrenal gland was slightly enlarged, with slightly increased FDG uptake (SUVmax = 3.0); the right adrenal gland showed no obvious abnormalities on contrast.
The esophagus was not dilated, and the esophageal wall was not significantly thickened or swollen, with no increased FDG uptake.
The stomach was poorly distended, with slightly thickened gastric walls and slightly increased FDG uptake (SUVmax = 2.5).
The intestines were poorly distended, with increased FDG uptake in parts of the colon and rectum (SUVmax = 5.5).
The prostate gland appeared normal in shape and size, but contained a high-density lesion.
FDG uptake was normal.
The bladder was poorly filled, but no obvious positive stones were observed.
No enlarged lymph nodes were seen in the abdomen, pelvis, or retroperitoneum.
No significant fluid accumulation was observed in the abdomen or pelvis.
Some vertebral bodies showed marginal osteophyte formation.
Some nuchal ligaments showed calcification.
Schmorl's nodes were observed at the lower margins of the T7 and L4 vertebral bodies.
L4/5 and L5/S1 intervertebral disc bulges were observed, but FDG uptake was normal.

Impression

1. a. Slightly low-density nodules with increased FDG metabolism in the lower segment of the right lobe of the liver, suggestive of malignancy, such as cholangiocarcinoma or poorly differentiated hepatocellular carcinoma. Please confirm with pathology. b. Several small cysts in the liver.

2. Chronic inflammatory micronodules in both lungs. Please confirm with CT follow-up. A few post-inflammatory lesions in both lungs.

3. Absent after cholecystectomy. Accessory spleen. Mild hyperplasia of the left adrenal gland. Small cysts in both kidneys. Calcifications in the prostate.

4. Increased FDG metabolism in the stomach wall, colon, and part of the rectum, suggestive of physiological metabolism or chronic inflammatory changes. Please confirm with endoscopy follow-up.

5. Degenerative changes in the spine. Schmorl's nodes at the lower margins of the T7 and L4 vertebral bodies. L4/5 and L5/S1 intervertebral disc bulges.

6. No obvious abnormalities were found on cranial scintigraphy. A few inflammations in the right sphenoid sinus and bilateral ethmoid sinuses.

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.
