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, with punctate, slightly low-density shadows in the deep brain regions; no abnormalities were observed in FDG metabolism.
Slight widening of the ventricles, sulci, fissures, and cisterns was observed; the ventricles were symmetrical bilaterally, and there was no midline shift.
The eyeballs were symmetrical bilaterally, with no obvious abnormalities.
Thickening of the left maxillary sinus mucosa was observed, while the mucosa of the other paranasal sinuses was not thickened, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed; the palatine tonsils were symmetrical bilaterally, and FDG uptake was physiological.
The laryngopharynx was normal in morphology and structure.
The parotid and submandibular glands were normal in morphology and density, and FDG uptake was physiological.
The thyroid gland was normal in morphology and size, with uniform density; FDG uptake was normal.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
The lung markings are clear.
A ground-glass nodule in the apical segment of the right upper lobe, approximately 0.4 cm in long diameter, with a maximum CT value of -651 HU, was observed with normal FDG uptake.
Small solid nodules were present in the posterior segment of the right upper lobe and the apical-posterior segment of the left upper lobe, the largest approximately 0.3 cm in diameter, with normal FDG uptake.
Calcification was present in the right upper lobe, with multiple air-filled cavities in both upper lobes and scattered linear lesions in both lungs, all with normal FDG uptake.
Slight pleural thickening was observed bilaterally, without pleural effusion or pneumothorax.
No significantly enlarged lymph nodes were seen in the hilum or mediastinum.
The cardiac silhouette was normal.
The cardiac chamber density was lower than that of the myocardium, with partial calcification of the arterial walls (including the coronary arteries).
The esophagus was not dilated, and the esophageal wall showed no significant thickening or mass; FDG uptake was not increased.
The liver margins are not smooth.
An irregular low-density mass is present in the right lobe, with indistinct borders, measuring approximately 11.0*8.1*14.6cm, exhibiting heterogeneous density and increased heterogeneous FDG uptake (SUVmax=4.3).
Several other low-density nodules and masses are observed in the remaining liver, some containing slightly higher-density shadows.
The largest, located under the capsule of the left medial lobe, measures approximately 4.5*3.0cm, with increased FDG uptake (SUVmax=11.9).
Another cystic lesion, approximately 1.0cm in diameter, is seen in the right lobe, with absent FDG uptake.
The portal vein is dilated, and multiple varices are present in the lower esophagus and gastric fundus.
Hilar and retroperitoneal lymph nodes are visible, the largest with a short diameter of approximately 1.1cm, showing increased FDG uptake (SUVmax=3.1).
A small amount of ascites is present.
The gallbladder is enlarged, but the gallbladder wall is not thickened, and local FDG uptake is normal.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen is enlarged, but its density and FDG uptake are normal.
Both kidneys are normal in shape and size, with several cystic lesions in each kidney.
The largest lesion is located in the middle of the left kidney, with a long diameter of approximately 2.8 cm.
FDG uptake is absent in these lesions.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging is normal.
The stomach is adequately filled, with slight thickening of the gastric wall in the cardia and antrum.
FDG uptake is increased, with SUVmax = 3.9.
Intestinal filling is unsatisfactory, with a considerable amount of residual contents in the intestinal lumen.
No masses are observed in the intestinal tract, and FDG uptake is increased in some intestinal segments, with SUVmax = 2.9.
The prostate is normal in size, with calcifications observed within it.
FDG uptake is not abnormally increased.
The bladder is poorly filled, with no obvious positive stones observed.
The spinal alignment was normal, with some vertebral body margin osteophytes, and mild posterior displacement of the L1, L2, and L3 vertebral bodies.
Multiple thoracolumbar intervertebral disc bulges with pneumoconiosis and degeneration were observed.
FDG uptake of the whole skeleton showed no abnormalities.

Impression

1. a. Multiple intrahepatic lesions, some with increased FDG metabolism, suggesting possible hepatocellular carcinoma with multiple subfocal formation or intrahepatic metastasis. Some lesions show internal bleeding; please analyze in conjunction with MRI images from other hospitals. b. Changes consistent with cirrhosis, splenomegaly, portal hypertension with collateral circulation, and a cyst in the right lobe of the liver. Metastasis to some lymph nodes in the porta hepatis and retroperitoneum needs further investigation. Small amount of ascites.

2. a. Ground-glass nodule in the apical segment of the right upper lobe, with normal FDG metabolism, suggesting inflammation or atypical adenomatous hyperplasia; follow-up CT is recommended. b. Chronic inflammatory micronodules in the upper lobes of both lungs. Emphysema in both lungs, calcification in the right upper lobe, and scattered post-inflammatory remnants in both lungs. c. Slight thickening of the pleura bilaterally. Anemia changes, and calcification of some arterial walls (including coronary arteries).

3. Enlarged gallbladder. Bilateral renal cysts. Prostatic calcification.

4. Chronic inflammatory changes or physiological uptake in the cardia, antrum of the stomach, and part of the intestine.

5. Degenerative changes in the spine, with mild posterior slippage of the L1, L2, and L3 vertebral bodies, and multiple thoracolumbar disc bulges with pneumoconiosis and degeneration.

6. Deep lacunar ischemic lesions in the brain, with mild age-related brain changes. Chronic inflammation of the left maxillary sinus.

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.
