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 arms 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; local density and FDG uptake were normal, and there was no midline shift.
The bilateral eyeballs had normal morphology and contours, clear retrobulbar structures, symmetrical optic nerves, and no significant abnormalities in FDG uptake.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; there was no stenosis of the bilateral pharyngeal recesses or Eustachian tube openings; the bilateral 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.
Increased FDG uptake was observed in the left mandibular alveolar bone, with SUVmax = 4.8.
The thyroid gland is normal in shape and size, with uniform density, and FDG uptake is normal.
No enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region, and FDG uptake was normal.
Multiple solid nodules were observed in both lungs, with a long diameter of approximately 0.2-0.5 cm, and clear borders; FDG uptake was normal.
Scattered linear shadows and small patchy hazy shadows were observed in both lungs, and calcification was observed in the right lower lobe; FDG uptake was normal.
No pleural thickening was observed bilaterally, and no significant pleural effusion was observed bilaterally.
No enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions, and FDG uptake was normal.
The cardiac silhouette was normal, and myocardial FDG uptake was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
No significant thickening or mass was observed in the esophageal wall, and FDG uptake was normal.
The liver lobe proportions were disproportionate, the liver margins were not smooth, and the hepatic fissure was widened.
An irregular, mixed low-density lesion measuring approximately 6.8cm 4.7cm 4.2cm was observed near the top of the diaphragm in the right lobe of the liver.
The lesion had indistinct borders and partially protruded beyond the liver contour.
FDG uptake was increased, with an SUVmax of 7.3.
No significant widening of the main portal vein or dilation of intrahepatic or extrahepatic bile ducts was observed.
Small lymph nodes were seen at the porta hepatis, the largest with a short diameter of approximately 0.4cm; FDG uptake was normal.
A small amount of fluid was observed around the liver.
The gallbladder wall was slightly rough, but no positive stones or obvious masses were observed; FDG uptake was normal.
The pancreas appeared normal in morphology, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened; FDG uptake was normal.
The spleen was enlarged, but its density and FDG uptake were normal.
The left kidney was atrophied.
The right kidney appeared normal in morphology and size, with no obvious abnormal density shadows in the right renal parenchyma; FDG uptake was normal.
The right renal pelvis, calyces, and ureter were not widened, and no positive stones were observed.
Bilateral adrenal glands showed no abnormalities in morphology or density, and FDG uptake was normal.
Gastric distension was poor, with increased FDG uptake in parts of the gastric wall (SUVmax = 2.5).
Bowel preparation was poor; no obvious masses were seen in the intestinal wall, but increased FDG uptake was observed in parts of the intestine and anus (SUVmax = 3.5).
The prostate showed no abnormalities in morphology or size, with a transverse diameter of approximately 3.7 cm; calcifications were observed in the prostate, and FDG uptake was normal.
The bladder was adequately distended, and no obvious positive stones were observed.
Scoliosis was present, with osteophyte formation at the margins of some vertebral bodies, L2/3 and L3/4 disc bulging, and L4/5 and L5/S1 disc herniation.
Bone interruption was observed in the right 11th rib, and the right transverse processes of L1 and L2, with increased FDG uptake (SUVmax = 3.6).

Impression

  1. a. Irregular mixed low-density lesion near the diaphragm in the right lobe of the liver, with increased FDG metabolism, hepatocellular carcinoma is the primary consideration; please correlate with pathology. b. Cirrhosis, splenomegaly. Reactive hyperplasia of the hilar lymph nodes; please follow up to rule out other possibilities. Microhepatic effusion.

  2. Chronic inflammatory micronodules in both lungs, chronic inflammation and sequelae (including calcifications) in both lungs; please follow up with CT scans. Partial arteriosclerosis (including coronary arteries).

  3. Chronic cholecystitis. Left renal atrophy. Prostatic calcifications.

  4. Increased FDG metabolism in parts of the stomach wall and intestines, considered physiological uptake or chronic inflammation, hemorrhoidal changes; please follow up with endoscopy.

  5. Scoliosis with degenerative changes. L2/3, L3/4 intervertebral disc bulge, L4/5 and L5/S1 intervertebral disc herniation. Post-fracture changes of the right 11th rib, L1 and L2 transverse processes.

  6. No obvious abnormalities were found on cranial scintigraphy. Inflammation of the alveolar bone in the left mandible.

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.
