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.
The whole-body scan showed: The brain morphology and structure were normal, with no abnormal density shadows in the brain parenchyma, and no abnormal FDG uptake.
No widening of the ventricles, sulci, fissures, or cisterns was observed, with no abnormalities in local density or FDG uptake, and no midline shift.
The bilateral eyeballs had normal morphology and outline, with clear retrobulbar structures and no abnormal FDG uptake.
Slight thickening of the ethmoid and maxillary sinus mucosa was observed bilaterally, while the mucosa of the remaining paranasal sinuses showed no thickening, and the sinus walls were intact.
No significant thickening of the soft tissue on both sides of the nasopharyngeal wall was observed, the bilateral pharyngeal recesses were symmetrical, and FDG uptake was normal.
FDG uptake in the bilateral palatine tonsils was physiological.
The laryngopharynx morphology and structure were normal, and the parapharyngeal spaces were clear.
The parotid and submandibular glands were normal in size, shape, and density, and FDG uptake was physiological.
The thyroid gland was normal in shape and size, with no obvious abnormal density shadows, and FDG uptake was normal.
Bilateral deep cervical spaces and submandibular lymph nodes were visualized; the largest was located in the right superior deep cervical space, measuring approximately 0.8 1.1 cm, with increased FDG uptake (SUVmax = 2.5).
Multiple ground-glass nodules and patchy lesions were seen in both lungs, predominantly in the right upper lobe.
Most had relatively clear borders; the largest was located in the apical segment of the right upper lobe, with a long diameter of approximately 0.6 cm and a maximum CT value of approximately -635 HU.
FDG uptake was normal.
Multiple small solid nodules were seen in the upper lobes of both lungs and the right middle lobe; the largest was located in the lateral segment of the right middle lobe, with a long diameter of approximately 0.5 cm.
FDG uptake was normal.
A few patchy and linear shadows were seen in both lungs, with FDG uptake normal.
Slight thickening of the pleura bilaterally, with no obvious pleural effusion.
Multiple small lymph nodes are visible bilaterally in the hilum, anterior and posterior to the vena cava, aortic window, and para-aortic arch, with high density; the largest has a short diameter of approximately 0.6 cm.
FDG uptake is increased, with SUVmax = 2.3.
The heart size is normal.
The esophagus is not dilated, and the wall is not significantly thickened or lumped; FDG uptake is not increased.
The stomach is well-filled, with slight thickening of the antral wall and increased FDG uptake on the posterior antral wall (SUVmax = 2.3).
Intestinal filling is unsatisfactory; no local masses are seen, and FDG uptake is normal.
The liver's shape and size are normal; the liver margin is irregular, and the hepatic fissure is not widened.
Multiple mixed-density nodules and masses were observed within the liver parenchyma, with indistinct borders.
Some contained patchy low-density lesions, while others contained punctate calcifications.
The largest nodule, measuring approximately 6.2 5.6 5.7 cm, was located in the lower segment of the right lobe of the liver.
It was predominantly isodense, with increased FDG uptake, some showing ring-like uptake (SUVmax = 3.9).
No dilation of intrahepatic or extrahepatic bile ducts was observed.
Multiple enlarged lymph nodes were observed in the porta hepatis, hilar space, and right cardiophrenic angle.
The largest, located in the hilar space, measured approximately 1.3 3.2 cm, with increased FDG uptake (SUVmax = 3.6).
No significantly enlarged lymph nodes were observed near the major blood vessels in the retroperitoneum, and their FDG uptake was normal.
No significant ascites was observed in the abdominopelvic cavity.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall, no positive stones or obvious masses, and normal FDG uptake in the gallbladder fossa.
The peripancreatic spaces are clear, with no obvious abnormal density shadows in the parenchyma.
The pancreatic duct is not widened, and FDG uptake is normal.
The spleen is of normal shape and size, with no abnormalities in density or FDG uptake.
Both adrenal glands are normal in shape, size, and density, with no abnormalities in local FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the renal parenchyma, and no obvious abnormalities in FDG uptake.
The renal pelvis, calyces, and ureters are not widened, and no positive stones are observed locally.
The prostate is normal in shape and size, with punctate calcifications observed internally, and no focal abnormal increases in FDG uptake are observed.
The bladder is poorly filled, and no positive stones are observed within the bladder cavity.
The spinal alignment is normal, with a small amount of bone hyperplasia at the edges of some vertebral bodies, and L4/5 intervertebral disc bulging.
No abnormal uptake was observed in FDG.

Impression

1. a. Multiple mixed-density lesions in the liver with increased FDG metabolism, highly suggestive of hepatic malignancy with intrahepatic dissemination, with possible metastasis to the hilar region, hilar space, and right cardiophrenic angle lymph nodes. Please combine enhanced MRI and tumor markers for comprehensive judgment. b. Trend towards cirrhosis. Reactive hyperplasia of mediastinal and bilateral hilar lymph nodes.

2. Slight thickening of the gastric wall in the antrum with locally increased FDG metabolism in the posterior wall, highly suggestive of chronic inflammation. A follow-up gastroscopy is recommended to rule out other possibilities.

3. a. Multiple ground-glass opacities in both lungs with no increased FDG metabolism, mostly suggestive of chronic inflammatory nodules, some of which may be atypical adenomatous hyperplasia. Please have a follow-up HRCT 3 months after initial discovery or after regular anti-inflammatory treatment. b. Multiple solid nodules in both lungs with no increased FDG metabolism, suggestive of chronic inflammatory nodules.? c. Minor chronic inflammation and sequelae in both lungs.

4. Prostatic calcification.

5. Partial vertebral osteophyte formation. L4/5 intervertebral disc bulge.

6. No obvious abnormalities seen on cranial scintigraphy. Minor chronic inflammation in both ethmoid and maxillary sinuses. 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.
