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, and resting, a whole-body PET/CT scan was performed with both hands raised, extending from the top of the skull to the upper thigh.
The scan showed: Normal brain morphology and structure; a high-density nodule with relatively clear borders, approximately 1.1 cm in long diameter, was visible adjacent to the left parietal bone, with no significant abnormalities in FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
Both eyeballs were symmetrical and showed no significant abnormalities.
Thickening of the mucosa of the left maxillary and frontal sinuses was observed, but the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, and FDG uptake was normal.
The pharyngeal recesses were symmetrical, and there was no stenosis of the Eustachian tube openings.
The infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear, with no abnormalities in FDG uptake.
No abnormalities were observed in FDG uptake of the oropharynx and laryngopharynx.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in shape and size, with uniform density, and FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region; FDG uptake was normal.
Multiple solid nodules were observed in both lungs, with relatively clear borders; the largest nodule was approximately 0.8 cm in length, and some were calcified; FDG uptake was normal.
Scattered linear opacities were observed in both lungs; FDG uptake was normal.
The pleura was slightly thickened bilaterally, but there was no pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The walls of the aorta and coronary arteries were partially calcified.
The breasts were relatively dense bilaterally; FDG metabolism was normal.
The liver margins were not smooth, the hepatic fissures were widened, and the liver lobe proportions were disproportionate.
A slightly low-density mass was observed in the posterosuperior segment of the right lobe, with relatively clear borders, approximately 5.5 cm 5.1 cm; FDG uptake was increased, SUVmax = 4.0.
Multiple cystic lesions were also observed in the liver, with relatively clear borders; the largest nodule was approximately 0.7 cm in length; FDG uptake was normal.
The main portal vein showed no significant widening, and the intrahepatic and extrahepatic bile ducts were not dilated.
The gallbladder was normal in shape and size, with no thickening of the gallbladder wall and no abnormal FDG uptake in the affected area.
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 abnormal FDG uptake.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma, no widening of the renal pelvis, calyces, or ureters, and no obvious abnormal FDG uptake.
Bilateral adrenal glands showed no obvious abnormalities on contrast imaging.
The esophagus was not dilated, with no obvious thickening or mass in the esophageal wall, and no increased FDG uptake.
The stomach was poorly distended, with no obvious thickening of the gastric wall and no obvious abnormal FDG uptake.
The intestines were poorly distended, with no obvious thickening or mass in the intestinal wall, and FDG uptake was physiological.
The uterus was normal in shape, with no abnormal density shadows and no abnormally increased FDG uptake.
No abnormal FDG uptake was observed in the bilateral adnexa.
The bladder is generally full, and no obvious positive stones are seen within it.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region, and FDG uptake is normal.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes, and L3/4 and L4/5 intervertebral disc bulges, but FDG uptake is normal.
The right 7th rib cortex is discontinuous, with increased FDG uptake (SUVmax = 5.1).

Impression

1. a. A slightly low-density mass in the upper posterior segment of the right lobe of the liver, with increased FDG metabolism. Combined with our center's MRI, hepatocellular carcinoma is suspected. b. Liver cirrhosis, multiple intrahepatic cysts. c. Discontinuous right 7th rib with increased FDG metabolism, suggesting possible fracture; follow-up is recommended to rule out metastasis.

2. Multiple chronic inflammatory nodules and calcifications in both lungs, with a few post-inflammatory remnants in both lungs. Slight thickening of the pleura bilaterally. Calcification of some arterial walls (including coronary arteries).

3. Spinal osteophyte formation. L3/4 and L4/5 intervertebral disc bulge.

4. Possible left parietal meningioma; enhanced MRI follow-up is recommended. Inflammation of the left maxillary and frontal 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.
