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 images showed: Normal brain morphology and structure; no abnormal density shadows were seen in the brain parenchyma; no significant abnormalities in FDG uptake were observed.
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 left ethmoid sinus mucosa was observed.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical, and FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology and structure.
The parotid and submandibular glands showed normal morphology and density, and physiological FDG uptake was observed.
The thyroid glands showed normal morphology and size, uniform density, and no abnormalities in FDG uptake.
Bilateral deep cervical spaces, submandibular, and submental lymph nodes were observed; the largest was located in the right deep cervical space, with a short diameter of approximately 0.6 cm, and showed increased FDG uptake (SUVmax = 4.0).
The lung markings are clear, with multiple solid nodules in both lungs, predominantly subpleural, the largest approximately 0.3 cm in diameter.
FDG uptake is normal.
Multiple air-filled cavities are present in the upper lobes of both lungs, along with a few linear lesions.
FDG uptake is normal.
There is no pleural thickening, and no pleural effusion or pneumothorax.
Numerous small lymph nodes are visible in the mediastinum, the largest approximately 0.6 cm in short diameter.
FDG uptake is normal.
The cardiac silhouette is normal.
The esophagus is not dilated, and the wall is not significantly thickened or swollen.
FDG uptake is normal.
The liver margins are not smooth.
A low-density mass is seen at the top of the diaphragm in the right lobe, with indistinct borders, heterogeneous density, and containing fatty components, measuring approximately 7.3*5.1*6.8 cm.
FDG uptake is unevenly increased, with SUVmax = 4.3.
A small cystic lesion, approximately 0.7 cm in diameter, is seen in the left lateral lobe of the liver.
FDG metabolism is normal.
The main portal vein is not significantly widened.
Small lymph nodes in the porta hepatis and retroperitoneum are visible, the largest being approximately 0.6 cm in short diameter, with no abnormal FDG uptake.
No effusion is seen in the abdominopelvic cavity.
The gallbladder is enlarged, with multiple dense nodules within the gallbladder and the upper segment of the common bile duct, approximately 0.9 cm in diameter.
The gallbladder wall is thickened with increased FDG uptake, SUVmax=4.1.
The pancreas is normal in morphology, with no obvious abnormal density shadows in the parenchyma, and the main pancreatic duct is not widened; FDG uptake is not significantly abnormal.
The spleen is normal in morphology, size, density, and FDG uptake.
A soft tissue density nodule adjacent to the spleen, approximately 1.0 cm in diameter, is present; FDG uptake is not abnormal.
There are a few exudative shadows around both kidneys, and several small cystic lesions in the renal parenchyma, the largest approximately 1.2 cm in diameter, with no abnormal FDG metabolism.
The renal pelvis, calyces, and ureters are not widened; FDG uptake is not significantly abnormal.
The left adrenal gland is thickened; FDG metabolism is not abnormal.
The right adrenal gland shows no obvious abnormalities on contrast.
The stomach is adequately full, with slight thickening of the gastric wall in the antrum and a slightly elevated FDG uptake (SUVmax = 2.8).
Intestinal fullness is unsatisfactory; no masses are observed locally, but continuous FDG uptake is seen in some intestinal segments (SUVmax = 3.2).
The prostate is full, with calcifications visible.
A high-density lesion measuring approximately 2.6*2.3cm is seen in the right peripheral zone of the prostate, with elevated FDG uptake (SUVmax = 3.8).
The bladder is poorly full, with no obvious positive stones.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
No abnormalities were observed in the FDG uptake of the entire skeleton.

Impression

1. a. A low-density mass with increased FDG metabolism at the top of the diaphragm in the right lobe of the liver, highly suggestive of hepatocellular carcinoma. Please combine clinical findings with enhanced MRI for comprehensive analysis. Liver cyst. b. Possible reactive hyperplasia of the hilar and retroperitoneal lymph nodes. Please follow up to rule out mixed metastases.

2. Benign prostatic hyperplasia with calcification, a space-occupying lesion on the right side of the prostate with increased FDG metabolism, neoplastic lesion to be ruled out. Please combine PSA and enhanced MRI examinations, and perform a biopsy if necessary to confirm the diagnosis.

3. Chronic inflammatory nodules in both lungs, CT follow-up is recommended. Emphysema in the upper lobes of both lungs, a few post-inflammatory remnants in both lungs. Reactive hyperplasia of mediastinal lymph nodes.

4. Gallbladder and upper common bile duct stones, cholecystitis. Accessory spleen. Left adrenal hyperplasia. Bilateral renal cysts.

5. Chronic inflammatory changes in the antrum of the stomach and part of the intestine. Please follow up with endoscopy.

6. Degenerative changes in the spine, L4/5 and L5/S1 intervertebral disc bulges.

7. Cranial scintigraphy showed no obvious abnormalities. Chronic inflammation of the left ethmoid sinus. Reactive hyperplasia of bilateral cervical lymph nodes.

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.
